Diesel Emissions Hazard
DANGER
DIESEL EMISSION HAZARD!
Prolong exposure to diesel emissions will increase the risk of death or

severe health effects.
Only operate and maintain the equipment according to all applicable

instructions, procedures, laws, and regulations.
Study diesel exposure controls and implement solutions that are most
feasible for your case based on your site-specific risk assessment. Always
wear approved personal protective equipment.
International Agency for Research on Cancer has classified diesel exhaust as a carcinogen to humans.
Diesel exhaust includes gases, vapors and particles made up primarily of carbon, ash, metallic abrasion
particles, sulfates and silicates. In addition to severe long term health effects, diesel emissions cause short
term effects such as eye and respiratory irritation.
All mines and construction sites with diesel powered equipment must have documented diesel emission
control plans and monitoring programs to ensure that human exposure is reduced as low as practicable.
Risks must be assessed and control measures implemented according to the hierarchy of controls. All areas
where people may be exposed must be considered; work force and incidental exposure included.
All mines and construction sites with diesel powered equipment must follow and comply with all applicable
legislation and industry requirements relating to controlling and limiting worker exposure to diesel emissions.
Locally applicable information is available from various sources, including but not limited to legislation,
standards, guidelines, rules, safety bulletins, strategies, best practices, instructions and position papers.
The following equipment related control measures must be taken to control diesel emissions and related
exposure:
• Operate and maintain the equipment according to instructions, especially according to the engine
supplier’s instructions.
• Ensure equipment users are trained on how operator behavior affects emissions.
• Monitor the information provided by the control systems as well as the indicator lights. If any warning or
alarm appears, take corrective actions immediately.
• Avoid unnecessary idling of engine. Keep engine revolutions as steady as possible.
• If the equipment has a closed cabin, keep the cabin clean and in good condition. Keep windows closed.
Pay special attention to the air conditioning unit, filtration components and door and window seals;
ensure they are constantly maintained and in intended condition. Make sure that instructions provided
in pre-start inspection and maintenance checklists are followed.
• Ensure that maintenance personnel are trained on servicing cabins in order to effectively manage the
risk of exposure to airborne contaminants.

Practices outlined in the front of this manual.
xii
While we believe that we have properly identified several potential hazards that could result in property
damage or personnel injury, there are certain hazards which may be present that we have not contemplated.
Bad weather conditions as they relate to this topic include lightning, thunderstorms and severe rainfall.
Management’s Responsibilities
High winds, rainfall and cloud cover are often precursors to actual cloud to ground strikes notifying
individuals to take action. Many reported lightning accidents occur with sun, clear skies and no rain present
at the beginning as the storm approaches because; people ignore these precursors. Generally the lightning
threat diminishes with time after the last sound of thunder, but may persist for more than 30 minutes.
It is the responsibility of management to:
• Be aware of daily weather conditions within a 161 km (100 mile) radius of the mine property.
• Determine a plan of action relating to expected bad or unexpected weather conditions.
• Notify equipment operators of impending storms. Communication to equipment operators may be given
via two way radio and/or in person.
• Consider that drill operators need ample time to:
- Retrieve drill pipe from blastholes and well bottom.
- Lower masts to a horizontal position or position feed rails into feed supports.
- Give the drill engine an adequate cool down period prior to shutting machine down.
- Leave machine cabin or operator platform and transport to central meeting location.
• Give equipment operators an all clear signal after the storm has cleared the area.
NOTE: Supervisors! Recognize that equipment operators should be given adequate time to prepare the machine
to move to specific locations for safe keeping. Crawler mounted drill machines have a maximum travel
speed not exceeding 4.2 kph (2.6 mph).
Rainfall And Flooding

When notified of an impending storm, machine operators should:
• Move the drill machine to higher ground conditions. Never leave a drill machine at the lowest floor posi-
tion of a mine or quarry or in a low lying ditch that could trap water runoff.
• Move the drill machine to stable ground and away from unstable crests or the face. Never leave a drill
machine on the front face of the drill pattern while rain and severe weather pose a threat of loose ground
falls or washouts.
• When operating machines in a construction application, equipment operators shall move the drill
machine to higher stable ground. Never leave a drill machine in any construction zone roadway, river bed
or drainage ditch.
• Move the drill machine to stable ground away from high walls and any threat where rock or water erosion
may allow unstable ground to fall or slide.
Thunderstorms And Lightning

A publication written in MSHA Holmes Safety Association Bulletin April 2001 gives a simple flash bang
formula to calculate lightning proximity.
The FLASH BANG method is determined by counting the seconds between the visible lightning and the
sound of thunder. This delay in seconds when divided by 5 will give an approximate value in miles as to how
close the active lightning is to your worksite.
Safe Operating Practices for Drillers xiii

Example: when you see lightning and it takes (10) ten seconds to hear the thunder divide by (5) five. The
approximate distance of lightning proximity is 3.2 km (2 miles).
If the flash bang measurement is 30 seconds or less seek shelter immediately and remain indoors, away
from electrical devices, water and metal components.
Supervisors must notify equipment operators in a timely manner. This is to allow the drill operator adequate
time to perform the required operation principals needed and secure the machine in a safe manner.
• Equipment operators shall retrieve drill pipe from blastholes, secure drilling tools and lower mast to a hor-
izontal position into the mast rest supports. Understand that the mast in a vertical position with drill pipe in
the ground is capable of attracting high voltage lightning.
NOTE: If the operator and machine are inside or near a blast area follow procedures written in USA Federal
Metal and Nonmetal Mine Safety Standards 30CFR 56/57/58 manual.
• Equipment operators shall move the machine to secure ground as noted in the rainfall and flooding
description.
• Equipment operators shall give adequate engine cool down period prior to shutting machine down. Ade-
quate engine cool down periods range between 3 to 5 minutes. Follow engine manufacture specifications
as a standard.
• Equipment operators shall secure the machine, close doors and windows, leave the machine cabin and
dismount the machine in a proper 3 point contact with the boarding ladder.
• Equipment operators shall drive or be transported to a central meeting location away from bad weather
and storm conditions.
There are exceptions to the rules when bad weather develops and time does not permit adequate machine
preparation - shutdown principals.
Exceptions
If you do get caught in an electrical storm and have little or no time to prepare, remember that, no place is
absolutely safe from the lightning threat, however, some places are safer than others.
When operators are inside an enclosed stable structure such as a machine cabin or the truck cab it is
recommended that:
• all windows are closed

• all doors closed
• do not touch metal parts
• do not use two way radio communication
NOTE: Wait inside the enclosed cab as long as it takes for the storm or lightning to subside. Do not attempt to
dismount the machine when lightning is in your immediate work area.
• If lightning is present within a 32 km (20 mile) radius of your location be aware of your surroundings when
outdoors. Seek adequate shelter immediately.
• If lightning is present within the 32 km (20 mile) radius, and a decision is made to dismount the machine,
use a standard 3 point contact down the boarding ladder to dismount the machine.
• Move away from the machine quickly and into a enclosed vehicle or adequate shelter. Maintain a dis-
tance greater than 92 m (100 yards) to prevent electrical draw in the event lightning did strike the mining
equipment.
• Static interference on AM radio channels is another indicator as to lightning proximity.
• Lightning detectors are available aftermarket as a measuring instrument to determine lightning proximity.
Blasting crews are aware of lightning hazards and may have a lightning detector on site.
xiv
• If you are caught in the open with lightning nearby and shelter is not available the safest position to be in
is to be crouched down on the balls of your feet. Keep your feet as close to one another as possible.
• Do not allow your hands (or other body parts) to touch the ground. Use your hands to cover your ears and
brace for a loud thunderous bang.
• Lightning struck victims carry no electrical charge and should be given first aid treatment immediately!
Machine Maintenance
If lightning does strike a drill machine parked in any position (mast up or down), expect major component
failures. A total machine inspection is in order.
Electrical charge should dissipate immediately after impact.
Prior to climbing on board a machine known to have been struck by lightning use the back side of either hand
(knuckle side) to lightly touch the boarding ladder.

Tramming Disable Foot Switch

The tramming disable foot switch located on the cab floor, is designed to stop the drill during in an
emergency situation. During tramming the foot switch must remain depressed at all times. If the operator
releases the foot switch, hydraulic pressure supply to the final drives will stop, locking the final drive brakes.
Hydraulic Pressure Release

Hydraulic circuits maintain pressure after the machine is shutdown. If maintenance to a hydraulic component
or hose is to be done, relieve the pressure in the hydraulic system.
xvi
Prior to opening a valve hose fitting or removal of a valve assembly note the following:
• Gloves and PPE are worn.

• Release the hydraulic pressure at the hydraulic tank.
• Do not check for leaks with hands.
• The technician must release the hydraulic hose fittings slowly at first to minimize potential high pressure
hydraulic oil or PSO pressure squirting out through the hose fitting. Oil will drain out the loosened hose fit-
ting.
• With the hose fitting slightly loose, manually rock the hose from side to side.
• Slowly open the hydraulic hose fitting and alternate the hose fitting to release residual hydraulic oil pres-
sure while maintaining a barrier between the hydraulic fitting and technician.
WARNING
FALLING LOAD HAZARD
Breaking a supporting cylinder hydraulic line may allow the supported load
to fall causing personnel injury or death.
When working with cylinders and any apparent loads they may hold, ME-
CHANICALLY SUPPORT AND SECURE the load prior to performing any re-
pair work.
NEVER attempt to work on hydraulic cylinders without adequate safety train-
ing. Refer to bulletin SB243A for more information.
Hydraulic pressures may be trapped in the hydraulic system by design. For example the residual pressure
may be holding a load. A cylinder with attached components such as the rotary head and drill pipe weight,
require some means of residual pressure to hold the oil in check thus holding the load. Removing the
pressure may lead to a falling load and a potential safety condition.
1. Determine if mast is vertical or horizontal.

• If vertical, lock and support the rotary head in position so that it cannot fall.
• If horizontal, lock the rotary head into position so it does not move.
2. Disconnect the pilot line to the valve.
3. Connect a portable hydraulic pump to the pilot line input on the valve.
4. Pump the portable hydraulic pump to achieve sufficient pressure to open the holding valve and discharge
pressure between the holding valve and the cylinder.
5. After pressure has been released, disconnect hose slowly and drain off any residual oil and pressure.
Have a pan beneath the valve to catch spilled oil.
Contact your Sandvik representative for a copy of service bulletin SB243A for more information on releasing
stored hydraulic circuit pressures.

• Check all machine ignition points (engine block, exhaust manifolds, mufflers, turbo-chargers, etc.) to
make sure they are not in contact with any hoses.
• Keep the batteries secured in their compartment and covered.
• Never inject ether or other starting aids into the engine and compressor intake filter(s). Ether or other aids
drawn into the compressor can cause an explosion.
• Do not store flammable fluids on or in the immediate vicinity of the machine.
xviii
• Engine oil, hydraulic fluid and compressor oil are flammable. Do not operate a machine with leaking or
worn hoses or lines.
• Do not clean washable filter elements with flammable solvents, diesel fuel, kerosene, or gasoline.
• Do not attempt to perform welding repairs until all flammable materials including oil and fuel spills oily
rags, and rock and coal dust, have been isolated or removed from the machine.
• Disconnect the battery cables before welding on the machine.
• Keep tools away from exposed live electrical parts such as terminals, to avoid arching.
• If charging the batteries, always turn the charger off before making or breaking connections to the battery.
• The compound (ethyl ether) used in the engine starting aid system is extremely flammable. Changing the
cylinders and servicing this system should be done in a well ventilated area. Do not store or install the cyl-
inders in temperatures above 71° C (160° F).
• The anti-freeze compound (methanol) used in the air line anti-ice systems is flammable. Refill the system
with compound only in well ventilated areas, away from heat, open flames and sparks. Do not store or
expose this system or the compound to temperatures above 65° C (150° F), or in direct sunlight.
Fire Suppression
IN CASE OF FIRE
When a fire starts, the way you react is very important. As soon as you become aware of a fire, do the
following four things:
1. Turn the machine off.

2. Quickly actuate the fire suppression system by pulling
the safety ring pin and pushing down the plunger on the
actuator.
3. Get away from the machine. Take a hand portable extin-
guisher along if you can.
4. Stand by with the hand portable extinguisher.
RESULTS
• If you leave the machine running, it may add fuel to the fire or restart the fire with sparks.
• React quickly so the fire is caught before it grows too large.
• By leaving the immediate fire area, you protect yourself from windblown flames, explosions or other dan-
gers created by the fire.
• Heat remaining from the fire could cause re-ignition after the fire suppression system has discharged.
Because of this, it is important that someone stand by, at a safe distance, with a hand portable extin-
guisher. This standby should be maintained until all possibility of re-ignition is past.
• Read the attached documents concerning the fire suppression system specific to your drill. Exposure to
the fire suppression chemical use during a fire may be a hazard to your health.

3.4. Track Components
3.4.1. Idler Group (BH00008086)

The Idler Group track tensioning wheel sliding supports is lubricated with oil for life. The fork or the
cross member supports the front guide wheel and the other components. The spring unit acts as
protection for the complete undercarriage against overloads due to outside factors such (as dirt).
All the spring units must be bolted, fitted or secured on the fork of the front guide wheel for easy
fitting and removal. The grease filled cylinder of the tensioner unit (4) is used to correctly adjust the
track tension.

DANGER
STORED ENERGY HAZARD!
The spring unit is preloaded and hence dangerous. Breakage or tampering
may be dangerous to the operators!
Any kind of repair on the preloaded spring unit must be carried out by
qualified persons only and in specialized workshops that can guarantee the
necessary safety measures.
3.4.2. Idler (BH00009534)

The track tensioning unit (Idler or Idler Group) performs the following functions:
• Flexing action simultaneously guiding the track.
• Position adjustment by means of the sliding supports to adjust track pretensioning and to
guide the track during springing actions.
The track tensioning wheel is fitted in the frame in the respective guides and its sliding supports
allow it to move longitudinally.
The friction surfaces of the track tensioning wheel and the guides in the frame are greased at the
factory during initial assembly to reduce wear to a minimum.

3.4.3. Spring Unit

The function of the spring is to protect the complete undercarriage against overloads. An overload
may be caused by outside factors (dirt build-up) which cause increased track tension. In these
circumstances, the spring element reduces the load on all the components. The spring is perfectly
operational as long as there is no excessive debris on it.
There are various spring unit configurations that can be used depending on the specific application
and the load requirements. In compressed condition, the spring unit requires unloading to allow the
tie-rod to protrude with respect to the support surface.
TENSIONER UNIT GREASE

FITTING
3.4.4. Tensioner Unit (Idler Adjustment)
The track is held under the necessary tension by
means of a tensioner cylinder. If the undercarriage
components are worn or the terrain conditions
change, the track tension needs to be adjusted by
increasing or decreasing it. TENSIONING
CYLINDER
The tensioning cylinder is a standard design and
operates with grease. To tension or slacken the
track, the grease is applied through a special
grease valve on the cylinder, or the grease level
can be discharged by unscrewing the fitting by half
a turn. The grease-operated tensioning unit is
accessed through the holes positioned on the sides
of the steel frame
The access hole (1) to the tensioning unit is
3
covered with a plate (2) and fastened with bolts (3).
The tensioner unit operates by changing the 2
hydraulic pressure on the cylinder to adjust the
track tension. Grease is applied through a special
grease valve to increase the pressure on the cylinder to tighten the track or grease can be
discharged by unscrewing the valve by half a turn to decrease the track tension.

023501-002
Regularly check track wear to prevent damage to the track tensioner. Retensioning is not permitted
after the track has reached its wear limit. This would result in excessive stress on the undercarriage
components over the permitted limits and the safety conditions against breaking forces would no
longer be given.
3.4.5. Installing and Removing the Track Tensioning Unit (Idler Group)
DANGER
In any circumstances where you work on the track tensioning wheel unit,
you need to follow the appropriate steps to ensure that the machine cannot
move or be started.
Take caution when installing or removing a tensioning wheel unit.

An undercarriage not connected to the track by means of the sprocket is not locked by the parking
brake and could hence be subject to movements. The undercarriage must therefore be secured
using other means.
DANGER
There is a risk you run when working on or with shock absorbing elements.
Also bear in mind the risks you run when working on or with shock absorbing elements. If a
tensioning bar (tie-rod) is damaged or broken, there is a risk that a helical spring does not stay in the
preload position but causes the front guide wheel to slip out of the frame following sudden
slackening after the track has been removed. This possible risk condition is detectable when the
track stays under tension even after having discharged the pretensioning pressure from the grease-
operated tensioner.
NOTE: When working on track tensioners, make sure that any overflow of oil or grease is
collected and disposed of in such a way as to have the lowest possible environmental
impact. Before fitting or remove the guide wheel unit, you need to open the track.

3.4.8. Roller Assembly (Upper and Lower

Double Support)
The load-bearing rollers/support guides are
supplied as a complete unit. The complete unit must be replaced in the event of damage, repairs, or
when the wear limits have been reached.
The load-bearing rollers guide the track in the upper section and support the track in such a way as
to minimize its bulging and prevent damage to the adjacent components.
The sliding surface of the upper rollers has been hardened (not in the case of the support guides) to
prevent wear. They mount special screw ring units that allow perfect seal and prevent dirt from
penetrating, and they are permanently lubricated.
Upper rollers with double support (identical to the lower rollers).
UPPER ROLLER
LOWER ROLLER
The support guides are available in hard-wearing

steel configurations or in some cases in special
polyurethane.
Track Roller Assembly (BH00012912)
To replace the upper rollers, undo the mounting

bolts and remove it. Install the new roller using new
bolts and reconnect the track.

023501-002
The rollers are supplied as a complete unit. The complete roller unit must be replaced in the event of
damage or when the wear limits have been reached.
The lower rollers function as a guide for the track that transfer machine load to the ground. The
surface of the rollers have been hardened to reduce wear. It has “screw” seals to prevent
penetration of dirt and oil leaks.
To replace a roller, slacken the track and remove

the locking devices. Raise the undercarriage to
remove a lower roller.
Undo the bolts from the defective track roller,

remove and replace it. Should track guide be
installed, they must first be removed also. Install a
new roller with new bolts and tighten until it seats.
Reconnect the track as described in the following
chapter.
3.4.9. Covers (BH00012917 & BH00015017)

MOTOR
The covers shown in the illustration below are GUARD
provided with all the standard undercarriages (not COVER
all the covers are provided with all the
undercarriages).
Additional covers not shown in the illustration may
be provided with the undercarriages. The most
common covers are those for the hydraulic or for
the manual access hole to the grease valve of the VALVE
tensioning unit. COVER
Be careful when handling the cover plates as they

may be heavy depending on their size and hence be a source of injury.
The covers are made of sheet metal and have the following function:
• Close hydraulic units and lines
• Provide protection against dirt and contamination
• Protect against personal injury.

023501-002
3.5. Track Chain and Pad Assembly (BH00012902)
The track chain consists of right-hand and left-hand

BUSHING CHAIN
links. The chains link together with bushings and
pins pressed together to make up different lengths.
The tracks have been induction-hardened making PAD
them extremely hard-wearing.
The pads are bolted onto the chain and form a
complete unit in compliance with the project
specifications. Pads general have one or two
grousers, some have three. PIN
The chains and pads recover the loads caused by
the machine and transmit power to move the
machine. The pads are hardened to reduce wear.
3.5.1. Track Chain and Pad Replacement

These instructions describe the correct method to
secure the pads to the chain. Incorrect fitting is the
most common cause of detachment between the
pad and the track.
It is often underestimated how important it is to
correctly carry out the pad replacement procedure.
Incorrect installation can cause bolt skimming or in 3 GROUSER
the worst case damage the track links. During 2 GROUSER
replacement of pads, the following is 1 GROUSER
recommended:
PIN SIDE of LINK
• Always use new bolts and nuts when installing
pads. Used bolts may be deformed and no
longer deliver the required tightening force.
• Position the pads with the front edge on the pin
side of the track link.
• Apply a thin layer of oil to the threading and the
contact surfaces under the bolt heads. FRONT EDGE of PAD
• Fit the bolts in the holes and tighten them in the
nuts several turns.
• Make sure that the flat part of the nut rests on its seat in the link (the rounded side of the nut
must face the sliding surface of the link).
• Fully tighten the bolts without applying particular force.
• Remove any form of materials or foreign bodies from the contact surfaces of the links, which
may wedge in between the pads and the bolts (e.g. paint, primer, rust, dirt, etc.) by brushing or
grinding the surface if required to clean the surface.
• Clean the contact surfaces and the seats of the track link nuts.

023501-002
WARNING
Fitting or removing hardened chain bolts by hammering poses a serious risk
to the operators because of projecting broken chips of material. Wear
appropriate personal protective equipment to prevent injury (e.g. wear
protective goggles, gloves).
Select the proper tightening procedure (see below) and determine the required torque from the
Torque Table. Tighten the bolts crosswise.
NOTE: Do not apply an excessive tightening torque to the bolts!
The bolts torques must be rechecked after 50 hours of initial operation. Further checks must be
carried out at regular intervals based on operator experience or manufacturer’s recommendations.
3.5.2. Tightening Procedure for Track Bolts

The tightening torque for each single bolt is obtained with two different tightening procedures:
dynamometric procedure and angular method. The angular method is used to exclude the incidence
of friction factors as much as possible. This is why this method is preferable to the dynamometric
tightening procedure. The tightening torque levels are specified based on the ISO strength classes
11.9 and 12.9, and 13.9 for special bolts.
• Angular Tightening Procedure:

In this procedure, preferable for on-site working conditions, the bolts are first tightened crosswise, to
an established torque value indicated in the Torque Table. The bolts are then pre-tightened by a
further 1/3 turn of the wrench (120°). With this procedure, a certain plastic deformation of the bolts
occurs in order to reach the maximum tightening value for each single bolt.
• Dynamometric Tightening Procedure:

Tighten the bolts to the torque value indicated above. The torque level should be reached using a
torque wrench applying a uniform rotary movement. Sudden actions generate torque peaks
producing incorrect results. Stop tightening as soon as you reach the pre-established tightening
torque.
NOTE: In both cases, excessively tightening the bolts over the values specified may damage
them beyond the yield point associated with an over tolerance plastic deformation with
the consequent risk of premature failure of the bolt.

3.5.3. Installing the Track on the Undercarriage
Spread out the track as shown so that it is as

straight and flat as possible.

023501-002
Position a wooden wedge under the end of the

track (front guide wheel side, bushing side of the
free track facing up).
Position the assembled frame on the track.
NOTE: It is important to position the frame so that

the forward drive of the machine is in the
same direction as the chain.
When the track is correctly aligned, pull it over the

final drive unit in the direction of the front guide
wheel above the side section. Make sure that the
chain bushings lock into the compartments of the
sprocket.
Position the ends of the track on the front track

tensioning wheel.

023501-002
Grease two shims and fit them in the bores of the

track links (also use sealing washers if necessary).
Align the track segments. Grease the tips of the

master pins and fit them in the holes. Push them
inside using a mallet if the tracks are small. If the
chain needs it, put the blocking pin in position to
guide the master pin inside the master links. Follow
the safety instructions. Fitting and removing the
pins with a mallet may cause dangerous projection
of materials.
NOTE: Wear personal protective equipment

(e.g. goggles, gloves, etc.).
For large tracks, fit the pins in place using a

hydraulic pin driver. If the chain has a small pin to
fix in position of the master pin, put it on.
3.5.4. Tensioning Track
When all the track components are in the correct

position, use a grease gun to tension the track. Fit
the grease hose connector on the valve of the
grease-operated tensioner.
Keep the grease gun under pressure during the
track tensioning.

023501-002
Important! When setting the track tension, there
L
must be a sagging (F) in the track of 2-3 cm for a F
track length (L) of 1-1.5 m. This is measured
linearly for a length (L) between 1 and 1.5 meters
(at least 4 track elements).
Check the sagging (F) using a straight-edge and
ruler to measuring the distance (F) from the top
edge of the pad to the straight-edge.
TOO LOOSE
NOTE: If the track is to slack, it may slip off the
roller flanges, the sprocket and the front
guide wheel and considerably increase
track wear. If the track is too taut, the
tracks increase wear on the front guide
wheel and the bearings and results in a
high degree of wear on the track TOO TIGHT
bushings and pins. It also requires
greater motive power during driving with
consequent increased fuel consumption
Detach the grease gun connector when the track
tension is correct. Move the undercarriage forward
and backward for one complete turn of the
sprocket and make adjustments as required.
Check the track position on the front guide wheel and on the sprocket.
Depending on the configuration, on some models there might not be any sagging in the upper
section of the track. In this case, the track tension can be adjusted by measuring the hydraulic
pressure of the tensioning device or lifting the undercarriage. The sag measurement in the upper
section in this case is the same rules as above where the distances L and F apply.
3.5.5. Rock Guards (BH00012909, BH00012910, BH00012911)

The rock guards or track guides go into action each time track flexures occurs when the
undercarriage needs to surmount an obstacle that may cause the track to slip off the track roller
flanges. There are various types of track guide. The main difference lies in welded and bolted
configurations. There are main three configurations of track guides:
• Track guide in the configuration with welded

segments where the undercarriage must be lifted
for fitting or removal.

023501-002
• Track guide in the configuration with bolted

segments where the undercarriage does not need
to be lifted for fitting or removal. These type are
without joining cross member.
• Track guide in the configuration bolted on the

entire length of the side frame where the
undercarriage does not need to be lifted for fitting
or removal.
3.5.6. Track Guard Installation

In the case of a welded configuration, the undercarriage must be lifted in order to fit the track guide,
since it cannot be fitted on the side. After lifting the undercarriage, the track guide must be fastened
to the undercarriage with bolts. For removal, work in reverse of fitting order.
In the case of a bolted configuration, the track guide can be installed without having to lift the
undercarriage, since the guide is made up of several separate parts. In this case, one side of the
track guide is bolted onto the undercarriage. The cross member is then connected to the first side of
the track guide. The second side of the guide is bolted to the cross member then bolted to the
undercarriage. For removal, work in reverse order to fitting. Make sure that there is no contact
between the guide and the track roller body and that there is adequate clearance between the guide
and the track (protrusion of the track pin).
3.6. Final Drive (BH00013681)
The complete final drive unit is made up of the following components:

• Sprocket (BH00012919)
• Final Drive/Motor Assembly or reduction unit (BH00013681) consisting of:
• Final Drive (BH00015021)
• Hydraulic Drive Motor (BH00010627)
• Integrated brake/Release mechanism (multi-disc brake)

To turn gearboxes upside down it is necessary to

use the hanging points provided for lifting
operations, and in accordance with the rules which
have been previously defined.
Wear ever gloves to provide appropriate
mechanical protection to the hands.
The upside down operations must be carried out by
keeping the gearbox as close as possible to a table
top; it is important to pay attention to its center of
gravity so that its weight does not get unbalanced
during this handling process.
Gearbox must be made secure so that the hooks
do not come out of the hanging points and cannot
move or cause risks of falling loads; this is very
important when the upside down turning operation
is carried out by means of ropes or lifting bands
which are more subject to displacement risks from
loads hanging points.
WARNING
Remove any dirt from the parts and the fastening elements. Use a hoist to
prevent the final drive from dropping while removing the bolts from the

3.6.9. Parking Brake Description

The multi-disc parking brake is integrated in the final drive unit on the motor side and is lubricated
with the final drive oil. The brake does not require any maintenance and only needs to be checked
at the time of general service of the complete final drive unit.

023501-002
The multi-disc brake parking brake is kept closed by thrust springs. If repairs are required, it must be
removed from the final drive and replaced as a complete unit. This configuration protects all the
individual parts, such as the discs, springs, and sealing parts from outside influences. Any repair
operation should be carried out exclusively by a specialized workshop.
NOTE: The brake circuit must be bled after any work on the unit or on the hydraulic couplings.
WARNING
Be careful when filling the final drive with hydraulic oil. There is sufficient
pressure in the feed circuit to cause the brake to release and may allow the
machine to move unexpectedly.
3.6.10. Parking Brake Release

Undercarriages with a transmission unit equipped with a parking brake cannot be moved if the
hydraulic system is not operational. For this reason, a release mechanism can be fitted on the
undercarriage. This mechanism allows the undercarriage to be towed when the diesel or electric
motors are off.
As shown below, the release device is positioned on the outside of the transmission and is held in
place by bolts. To release the parking brake, remove the bolts and screw the toothed key. Make
sure that you put the release device back to its original position before returning to normal
operation. Be very careful, as manually releasing the brake poses a risk of the machine
unexpectedly starting.
3.6.11. Final Drive Disassembly Preparation

If a repair of the final drive becomes necessary it must be removed from the machine. This is not
required for normal maintenance procedures. Only experienced repair personnel should perform
this procedure.
This procedure must be performed in a workshop that has adequately tools. Special tools that are
required can be ordered from the Sandvik Service Department or fabricated on site. To be able to
fabricate this equipment, drawings are provided at the end of this manual.
The procedures for disassembling and assembling the gear motor given below must be strictly
adhere to.
Proceed with these operations using the following safety measures:

023501-002
1. Cover all the hydraulic system connections on the gear motor to avoid the introduction of
any foreign parts in the circuit and the gear motor.
2. Protect all coupling surfaces to prevent damage to seals and threads.
3. Handle components to ensure that there are no risks for human safety and to guarantee
the reliability of the gear motor.
4. Prepare a work area that is clean and meets workplace safety guidelines.
NOTE: Follow the steps below during these operations. The numbers in brackets with the text
correspond to the component references in the exploded view.

The motor maintenance requires only periodic
visual inspections for any seepage.
During motor repair or replacement, insure that the
hydraulic delivery and return lines are correctly
connected or the drive controls will reverse the
machine direction. MOTOR
3.7.1. Installing the Motor
NOTICE
Under no circumstance remove the plastic lid from the power supply ports
of the hydraulic motor; this will help avoid the accidental introduction of
foreign bodies into the motor, until the hoses are assembled.
In case of hydraulic motor installation, the following precautions must be observed:
• Do not force the coupling and do not use inappropriate tools during assembly. Take care not to
damage the flat/cylindrical coupling surfaces.
• Do not force the rotary coupling mechanisms with heavy overhung or thrust loads.
• To facilitate assembly and avoid the rotary coupling mechanisms wear, use a lubricating
synthetic oil paste (e.g. Klüberpaste 46 MR 401 or Tecnolube WRL 115).
• Install the O-ring seal in its seat in the hydraulic motor and assemble it to the gearbox being
careful not to damage the seal already fitted.
• Use a torque wrench to tighten the bolts to install the motor to the correct torque.

Complete the following steps when replacing the final drive motor:
FINAL DRIVE
DRAIN
1. Fill the motor housing with the correct PORT
hydraulic oil through the drain port.
2. Bleed air from every part of the hydraulic
circuit and add hydraulic fluid in the tank if
necessary.
3. Start the final drive at a low speed and
gradually increase it after having verified
that it functions correctly without any
noises or vibrations. MOTOR
NOTE: The presence of residual air in the hydraulic circuit will manifest itself with the presence
of foam in the tank and will lead to a jerking of the motor as well as excessive noise
coming from the motor and the valves.
4. Start the final drive at a low speed and gradually increase it after having verified that it
functions correctly without any noises or vibrations.
NOTE: Do not reach maximum pressure unless the entire system has been filtered to
eliminate any particles of dirt that may be present.
5. Once the motor is operating, check the correct revolution and direction of rotation.
6. Make sure that the motor is functioning without any excessive noises or vibrations and that
the oil temperature does not exceed 85-90°C.
7. After the initial operation, check for oil leakages and verify the level of lubricating oil in the
motor.
8. Verify the functioning of the brake system by opening and closing them.

• Do not smoke in the presents of combustible liquids.
• Use caution in the presence of fire or combustion type heaters. Not only fuel but also other
commonly used substances may have a low flash point and easily ignite.
• Use lubricants must be disposed of properly to lessen environmental impact.
3.8.3. Lubricant Requirements
NOTICE
When using synthetic lubrication, use only oils with PAO base.
Do not mix together oils of different brands or characteristics.
Use only recommended products in order to insure brake performances.
Oil temperature should not exceed 90oC (200oF) during operation.
In operating conditions from +10° to + 30°C (50° to 85°F), use the recommended lubricants that
meet the viscosity requirements for final drive lubrication. Observe the degree of viscosity marked
on the data plate that shows the viscosity necessary (SAE 80W/90 mineral and SAE 75W/90
synthetic) for these operating conditions.
In extreme operating conditions for - 30° to + 50°C (25° to 120°F), it is recommended to use final
drive oils with an adequate viscosity or use 100% synthetic lubricant.
For lower operating conditions from -20° to + 30°C (-4° to 85°F), use an oil with a lower viscosity
(SAE 80W/90) and for higher temperatures from +10° to + 45°C (50° to 115°F), use an oil with a
higher viscosity (SAE 85W/140 mineral and SAE 75W/140 or SAE 80W/140 synthetic).

(001022-000)
GENERAL
The following procedures are for driveshafts
manufactured by Spicer as the 1550 series.
The following topics are discussed; safety,
inspection, lubrication, and problem analysis.
SAFETY PRECAUTIONS
3. Check the slip spline for excessive radial
movement. Radial looseness between the slip
yoke and the tube shaft should not exceed .17
! WARNING mm (.007 inch).
Rotating driveshafts can be dangerous. You

can snag clothes, skin, hair, hands, etc.
This can cause serious injury or death.
Do not work on driveshaft (with or without a

guard) when machinery is operating.
If driveshaft is still exposed after installa-

tion, install a guard.
4. Check the shaft for damaged, bent tubing

1. Apply grease gun pressure to the lube fit-

hole in the plug at the slip yoke end of the
spline.
2. Now cover the pressure relief hole with

your finger and continue to apply pressure until
grease appears at the slip yoke seal.
1. Use the proper lubricant to purge all four

seals of each U-joint. This flushes abrasive
contaminants from each bearing assembly and
assures all four are filled. Pop the seals. Spicer

Engine and Compressor Specifications Page 3
Engine and compressor packages are compati-
ble for specific drilling applications. Climactic
conditions and operating conditions such as
altitude, are factors in selecting the proper
power group components to fit the overall drill-
ing needs.
When selecting a compressor size and drilling

tools, use the following altitude correction chart
as shown.
ALTITUDE ALTITUDE CORRECTION

FEET METERS FACTOR
4000 1200 .86

12000 3700 .63

14000 4300 .58
Use the altitude correction table;
• For drilling applications above 4000 feet

(1200 meters).
• When determining actual compressor output

or standard cubic feet per minute (SCFM).
• In selecting the correct drill pipe and drill bit

dimensions for adequate up hole velocity.
Example:
900 CFM (25.5 m³) @ 5000 feet (1500 meters).

compressor output = 900 x.82 = 738 SCFM
1600 CFM (45.3 m³) @ 8000 feet (2400

compressor output = 1600 x.73 = 1168 SCFM

inlet orifice, the spring end is open to atmosphere through a vent muffler. The inlet control cylinder
extends with receiver air pressure passing through a normal open air control regulator. A .09375
(2.381 mm) orifice inside the inlet manifold plate draws air from the control signal hoses when the
low pressure regulator closes. The spring return cylinder closes the butterfly inlet plate.
Proper inlet adjustment is critical for machine start-up and receiver air pressures. The inlet cylinder

Calibrating Regulators
Perform air pressure regulator calibration with the machine shut down and receiver air pressure is
zero.
Pressure regulator may be calibrated in place on the machine with standard hand tools. It is advis-
able to install a 500 psi (35 bar) pressure guage and hose to the test port provided at the air/oil sep-
erator indicator.
1. Start the machine.
2. Operate the machine at low engine idle speed to warm fluids and air. Warm compressor oil and
air temperature is recommended prior to regulator calibration.
3. Operate machine to specific rated high engine idle speed.
4. Check air pressure guage for actual air receiver tank air pressure.
5. Adjust low pressure regulator adjustment screw in to increase air pressure to acheive 100 psi
(6.9 bar) unload air pressure.
Note:
If air pressure over runs the value reduce the regulator setting and slowly adjust the regulator to the
rated pressure value.
6. Check air pressure guage for actual air receiver tank air pressure.
7. Lower engine idle speed allow adequate engine cool down period prior to stopping machine.
8. Stop the machine per standard operating principals.
9. Allow approximately two to three minutes for the air pressure in the receiver tank to empty to
atmosphere. Air will blow to atmosphere through a frame mounted vent muffler.
10. Check receiver air pressure on test gauge for a zero indication prior to service.
11. Remove test pressure gauge from air/oil separator indicator location and cap test port adapter.
Final note:
The compressor lubrication system is dependant on operating air pressures. Compressor system
air and oil components are subject to system air pressures.
When testing oil coolers, test pressures are relative to air regulated pressures. With the exception of
lubrication component pressure drops test pressures will be air receiver tank pressure.
Blowdown Valves
Two valves mounted to the air control manifold enable air receiver tank pressure to vent to atmo-
sphere. As air vents to atmosphere it is silenced with a muffler mounted on the machine frame.

• The shutdown blowdown valve pilots closed for machine run mode and opens upon machine
shutdown to empty the air receiver tank
• The running blowdown valve pilots closed during compressor loading or drilling conditions and
opens upon compressor unload conditions to maintain a stable air receiver tank pressure.

PRESSURE REDUCING REGULATOR TO OPEN POPPET VALVE
With the receiver tank pressure at 100 psi (6.9 bar) the subtractive pilot valve outlet pressure setting
is approximately 5 psi (.34 bar) less than the pressure reducing valve outlet pressure.
When adjustments are made to the subtractive pilot valve increase or decrease values, a similar
adjustment is mandatory for the pressure reducing valve.
For best results make pressure adjustment with an external air source. Shop or service truck supply
air is recommended as long as the supply pressure is above desired subtractive pilot valve require-
ment.
• Attach supply air to the valve inlet port with 300 psi (20 bar) pressure gauge.
• Attach 150 psi (10 bar) pressure gauge to outlet port, the outlet side has to be in a dead head

• Utilize all safe operating principals when servicing air regulation parts. Discharge any un-
used air from hoses or adapter ports prior to component removal.

RESERVOIR
PILOT
SIGNAL
POPPET V1 PORT
These valves are supplied as normal closed pistons and require a separate pilot signal to open the
piston to vent air from the inlet to outlet port.
During machine run mode the final blow down valve is spring set closed to maintain air pressure
inside the air receiver tank. The pilot end is connected to the compressor inlet cavity which is a vac-
uum during compressor operation. The absence of pressure at the final blow down valve pilot port
allows this valve to maintain a closed position during machine operation.
When the machine is shut down, available receiver air pressure is inside the compressor. The com-
pressor inlet that was a vacuum during operation becomes pressurized at shutdown. Air pressure
from the system opens the final blow down valve according to a flow control setting. Air pressure
shall vent to atmosphere through a vent muffler positioned on the final blow down outlet port.
One adjustable flow control valve is positioned on the pilot port of the final blow down valve. This
flow control valve shall be set 1/4 turn open and locked in this position. Refer to figure six for details.
During machine run mode the running blow down (purge) valve is spring set closed until a pilot sig-
nal is received at the valves pilot port. When receiver air pressure opens the subtractive pilot valve,
a pilot signal is directed to open the running blow down valve. Compressed air recirculates from the
receiver tank to the poppet inlet control valve (V1) vacuum port.
Maintenance of these valves is limited to seals and orings, no adjustments required.

START MODE
The poppet valve is held closed with reduced air pressure passing through the bypass solenoid,
along with spring force in the P1 cavity.
The expected air pressure for start-up mode is approximately 10 to 15 psi during starting and the
bypass solenoid is energized with the bypass switch. The low air pressure is a low load for the com-
pressor and engine during the critical start-up mode. The 10 to 15 psi contained in the air receiver
tank pushes the oil through the oil lubrication parts to the single stage air end.
When the engine is running smooth at the rated low idle speed the bypass switch may be disen-
gaged.

With air pressure inside the air receiver tank at the rated subtractive pilot valve setting it is desired
to close the intake.
Subtractive pilot valve air is directed to the P1 cavity to close the intake. Spring force assists the
closing (add air pressure and 5 psi spring force).
Air pressure present from the pressure reducing valve is forced to the intake through a.090 orifice
located inside the poppet valve on the P2 port.
When adjusting maximum air pressure for receiver tank air it is necessary to adjust both regulating
valves in steps. If the subtractive pilot valve is adjusted for 5 psi more available air pressure inside
the air receiver tank then the pressure reducing valve requires the same increase of air pressure.
This step type adjustment is necessary for proper intake valve opening and closing sequences.

DROPS BELOW VALVE SETTING
When air receiver tank pressure drops below the subtractive pilot valve setting a pressure difference
occurs at the subtractive pilot valve inlet and outlet ports.
With inlet control pressure below the spring force the subtractive pilot valve will close air to the outlet
port. The outlet connection to orifice at P1 and a external vent on the valve, air pressure is vented
quickly. The poppet valve will open with air pressure in the P2 cavity.
A minimum pressure of 60 psi (4 bar) is maintained in the air receiver tank for adequate oil circula-
tion and lubrication. During the drilling cycle typical air receiver tank pressure is 60 to 75 psi. Pres-
sures may become higher due to drilling conditions.
Bit air or working air for drilling depends on what restrictions are in the drill string and what type of
drilling tools are being utilized. Working air pressure is typically 10 to 20 psi (.7 to 1.4 bar) lower than
air receiver tank air pressure.

SHUT DOWN MODE
Pressure inside the air receiver tank is available in all directions upon shut down. With the discharge
check valve removed air pressure can flow through the V1 port to a flow control valve. When this
flow control is set 1/4 turn open air under pressure will be trapped between the flow control and the
pilot port. This trapped air will pilot the final blow down valve to a open position enabling air pressure
to drain from the air receiver tank after shut down.
! WARNING
Depending on the flow control setting, air pressure may be present inside the air receiver tank for
long periods even after shut down. If the flow control valve is too far open or the adjustment is not
locked in place caution should be observed when servicing the air receiver tank or compressor oil
filters.

Troubleshooting Single Poppet Valve Inlet Control Systems
Low pressure compressor systems that require fieldmechanical adjustments most often have either
been tampered with or have worn components.
Subtractive pilot valves
When calibrating a subtractive pilot valve small turns on the set screw make sufficient changes to
the outlet air pressure. Turning the set screw in will decrease the outlet supply air value, which in
turn will not let the poppet valve respond and close efficiently. The outcome will be over run of air
pressure to a point of safety valve discharge air. Factory specs recommend setting the subtractive
pilot valve with shop air only per views shown on page 28 of this manual.
Pressure reducing valve
When calibrating a pressure reducing valve small turns on the set screw change the outlet air pres-
sure. Turning the set screw in will increase the outlet supply air value. It may be necessary to modify
the factory pressure reducing valve setting of 50 psi to achieve a full piston opening sequence.
Pressure reducing valve settings will affect vacuum readings.
Vacuum check
When testing the low pressure poppet intake system it may be necessary to connect a vacuum
gauge to the compressor throat. Components shall include a ball valve, short length of hose and
vacuum gauge. Close the ball valve for machine start-up and shut down modes.

Check the poppet valve oil level often. When the oil level is low the piston responds slower and
receiver air pressure may overrun the regulated value. If oil levels are continually low, requiring con-
stant refill a seal may be leaking the oil out of the piston valve chamber. This condition may give
symptoms of air regulation problems as well.
During cold weather conditions ice build-up inside the poppet valve may lead to operational prob-
lems. It may become necessary to install one 022462-001 coalescing filter to the main air line. This
filter is used to remove unwanted condensation that typically collects in the air components.

ROTARY DRILLING
GENERAL
Drill bits are consumable items attached to a drill string and utilized to advance the drill string into
earth formations for the purpose of making a blasthole or well hole. Many brand names exist in the
market. It is the users choice to purchase the best bit to optimize drill production in the mine specific
ground conditions.
DESCRIPTION
Principals of rotary drilling are quite simple. There are three main elements, air delivery, rotation
speed and torque and lastly feed force otherwise known as pulldown. The volume of air and the
operating pressures are essential for a successful blasthole.
DRILL BITS
The three most common rotary drill bits are the 3 and 4 wing drag bit, the roller or tri cone bit and the
claw type drill bits.

Each application drill bit type by manufacture is designed with limitations. The limitations could be
rotation speed, feed force and air flushing. Bit manufactures design variations to with stand and per-
form in differing strata.
Air Delivery
Optimum drill cutting removal is based on proper drill pipe diameter in relation to drill bit diameter
(hole size). Annular area is the difference of area between the drill bit and drill pipe diameters.

Inspecting Drill Bits
Inspect drill bits at the beginning of each shift and as needed according to rock strata. Replace worn
or damaged drill bits. Besided lost production damaged drill bits can affect rotation system compo-
nents and stress the hydraulic system.
In relation to air systems the main factors are air volume and uphole velocity and working air pres-

Nozzle selection is a machine specific and site specific requirement.
Nozzle Selection
Nozzles are designed to regulate high energy air at the intersection of adjacent cones to ensure
removal of loose rock cuttings and direct air to the bearings for cooling and dust removal.
Careful consideration must be given as to the correct nozzle size to ensure correct operation of the
drill bit.
Should the nozzle size be too large in diameter the pressure drop across the drill bit will be too
small. This will result in a larger proportion of air flow being directed through the nozzles and a small
proportion being directed to the bearings for cooling. Cutting material can be forced into the bearing
area reducing the service life of the bearings.
Page 72
1160 CFM

TO THE BEARINGS
If the nozzle sizes are too small in diameter the air pressure inside the drill bit will be too high caus-
ing the compressor to frequently unload resulting in poor flushing and drill performance.
Air Pressure Differential
1. Blow air to atmosphere through drill pipe and bit with nozzles. Check working air pressure
gauge.
2. Blow air to atmosphere through the rotary head top sub without drill pipe and bit. Check working
air pressure gauge.
Consult your local bit supplier for recommended nozzle sizes.
Adjust nozzles sizes accordingly.
Remove And Replace Nozzles
1. Clean the area around the spring pins and nozzles.
2. Drive the spring out using a 3/16 (5 mm) punch.
3. Remove nozzle from housing
4. Clean nozzle housing
5. Insert new nozzle into housing ensuring that the groove on the nozzle is aligned with the pin
hole.
6. Replace spring pin ensuring that the head of the spring pin is flush with the bit surface.

Drill/Propel Applications
The Gator, D25KS and D245S feed systems

use a Denison piston pump for propel/rotation
and propel/feed systems. Pump mounted mani-
folds require special torque discussed in the
supplemental pump component section of this
manual.
Each pump port manifold uses pilot assisted

directional control valves to switch pump port
flow to the dedicated system.

bar) enters manifold port V1 from a remote

DOUBLE PILOT CHECK

VALVE (001316-000
The double pilot check valve shown above is

used as a cylinder ‘locking device’ to hold
certain drill components in its last controlled
position. Some of the components you will
find this check valve on includes the holding
wrench and the drill pipe loader. As an
example, when the loader swing control lever
is returned to the ‘neutral’ position, the barrel
loader is ‘locked’ and will not vibrate or drift in
either direction until pressure is applied
through the control valve.
CHECK VALVE
If the cylinder does vibrate or drift out of its (USUALLY LOCATED
last controlled position, the check valve IN HYDRAULIC CABINET)
should be removed, thoroughly cleaned and
inspected. As replacement of component
parts are not recommended, the entire
check valve should be replaced if cleaning
the valve does not completely restore
‘locking’ of the component it is used with.

Safety
NOTICE
Make sure that the highest level of system operating pressure does not exceed the lowest
pressure rating of any component within the system. Remember: The 80% rule: It is safer to
use high pressure tools at 80% of their maximum rating instead of 100%.
The following general instructions and guides will be helpful to determine if your system components
are properly connected:
1. Be sure all hydraulic connections, hoses, fittings are rated for the highest pressure your system
is capable of generating. Always use hoses and tubing recommended by the manufacturer.
2. Be sure all hydraulic connections are fully tightened. Seal all pipe connections with a high-
grade pipe sealer or Teflon® tape.
NOTICE
Teflon® tape is an excellent thread sealer; however, if the improperly applied, pieces may
enter the hydraulic system causing malfunctions and damage. Use 1 ½” wraps of tape on
each thread. Cut off all loss tape ends.
3. DO NOT over-tighten any connections. All connections should be snug and leak free. Exces-
sive tightening will cause strain on the threads and casting which could cause fitting failure at pres-
sures below rated capacity.
4. Fully tighten hydraulic couplers (avoid excessive force). Loose couplers will act as a partial or
complete line restriction causing little or no oil flow and resulting in equipment damage or failure.
5. Be sure all hydraulic hoses and fittings are connected to the correct INLET and OUTLET ports
of the pump, cylinder, valves and other system components.
! WARNING
Do not exceed equipment ratings. Never attempt to lift a load weighing more than the
capacity of the cylinder. Overloading causes equipment failure and possible personal injury.
The cylinders are designed for a maximum pressure of 700 bar [10,000 psi]. Do not connect
a jack or cylinder to a pump with a higher pressure rating.
Never set the relief valve to a higher pressure than the maximum rated pressure of the pump.
Higher settings may result in equipment damage and/or personal injury.
Recommendations
• USE HYDRAULIC GAUGES WHICH INDICATE SAFE OPERATION LOADS IN EACH

HYDRAULIC SYSTEM - Gauges are available for use with all hydraulic components (some
Copyright © Sandvik Mining and Construction 1

gauges have a colored band to indicate rages for each cylinder). DO NOT exceed the safe limit
of the lowest rated component used within your system.
• DO NOT DROP HEAVY OBJECTS ON HOSE - A sharp impact may cause bends or breaks to
internal hose wire strands. Applying pressure to the damaged hose will cause the internal flex-
ing which will eventually break the hose strands causing the hose to rupture.
• DO NOT USE THE HYDRAULIC HOSE TO CARRY HYDRAULIC SYSTEM - (i.e. pumps, cyl-
inders and valves).
• DO NOT OVERLOAD CYLINDER - Never attempt to lift a load which exceeds the capacity of a
cylinder or jack. Overloading causes equipment failure and possible personal injury.
• DO NOT OVEREXTEND CYLINDER - The cylinder will take full load on the plunder top ring.
However, using the full stroke does not supply power and only adds unnecessary stain to the
cylinder.
• AVOID OFF-CENTER LOADS - Avoid situations where loads are not directly centered on the
cylinder plunger. Off centered loads produce considerable stain on cylinder plungers and may
slip or fall causing potentially dangerous results. Avoid point loading. Distribute the load evenly
across the entire saddle surface.
• PROVIDE ADAQUATE CLEARANCE - Always provide clearance for hoses and couplers to
avoid moving objects, abrasion or sharp objects.
• AVOID SHARP BENDS OR KINKS IN HOSE - Avoid sharp bends and kinks when routing
hydraulic hoses. If pressure is applied to a bent or kinked hose, the oil flow will be restricted
causing sever backpressure. Also the sharp bends and kinks will internal damage the hose
leading to premature failure.
• KEEP HYDRUALIC EQUIPMENT AWAY FROM OPEN FLAMES AND HEAT - Excessive heat
(above 66° C (150° F)) will soften packing and seals, resulting in fluid leaks. Heat also weak-
ens hose materials and packings. For optimum performance DO NOT expose equipment to
temperatures of 66° C (150° F) or higher.
• EXAMINE YOUR WORK AREA BEFORE PRESSURIZING THE HYDRAULIC SYSTEM -

Look for ways to protect yourself and others, and ways to protect your equipment and other
property. Keep the components clean at all times.
• KEEP THE PUMP AND COUPLINGS AS FREE FROM DUST AND DIRT AS POSSIBLE -
Uses only approved hydraulic fluid and change the hydraulic fluid often if used in extreme con-
ditions.
• NEVER STORE SYSTEM IN DIRECT SUNLIGHT OR NEAR A HEAT SOURCE - Store sys-
tem in an area where temperatures are between 10-24° C (50-75° F).
• PERFORM A VISUAL INSPECTION of all components prior to using equipment.
• REPLACE WORN COMPONENTS with “like-kind” equipment that is rated for the maximum
hydraulic system pressures.
• DO NOT move the hydraulic system by pulling or lifting on the couplings or hose.

• BEFORE LONG TERM STORAGE, fully extend and retract the plunger once. Then, store the
cylinder upside-down. This will help protect the cylinder from corrosion.
Hydraulic System Assembly

The components described below are connected together to form the hydraulic system as shown.
1. Make hydraulic connections as shown.
NOTE: NPT connections require thread sealant.

Leave first thread bare to prevent sealant or tape from
entering the hydraulic system.
2. Fully hand-tighten all couplers. Loose coupler

connections will block the flow of oil between the
pump and the cylinder.
NOTE: For easy make/break connections, install a

coupler in the gauge adapter port, then use a hose
with a coupler end instead of a threaded end.
3. Position the cylinder so that the plunger is pointed down and the cylinder is lower than the
pump. Fully extend and retract the cylinder several times, until operation is smooth. To remove air
from the cylinder, refer to “Removing Air From The Hydraulic System” section.
4. Install adapters and attachments as

required. (See diagram)

Before Using The Hydraulic System

• Check hoses and couplers. Hose should have a straight run and be free of tangles or kinks.
Coupler connections must be fully tightened.
• Check that all connections are tight and leak free. It is especially important to check all coupler
connections because, after the system has been pressurized, you will not be able to tighten the
couplers by hand and using tools will damage the couplers.
• Remove air from system. (See instructions below)
• Check oil level in pump reservoir. (See instructions below)
• Never get under a load.
• Use cribbing or blocking for load holding for long periods.
• Do not use hose to lift or pull the Hydraulic System.

Pump Operation
1. To advance cylinder plunger, turn pump release valve clockwise and close finger tight.
NOTICE
To avoid release valve damage, do not use tools to tighten valve.
2. Operate the pump handle to advance the plunger.
3. To retract the plunger, turn the release valve counterclockwise.
4. Pump can be operated from a horizontal or vertical orientation, as long as the hose end is
down.
Removing Air From The Hydraulic System
How To Tell If There Is Air In The Hydraulic System

Hydraulic system operation should be instant and smooth. For every pump stroke, the cylinder
should rise evenly. If the cylinder movement is erratic or jerky, there may be air in the system.
How To Remove Air From The Hydraulic System

INVERT CYLINDER
Air will always go to the highest point in the hydraulic
system. This includes the inside of the cylinder
plunger. To remove air from the system, invert the
cylinder and elevate the hand pump with the handle
end and vent at the highest point as illustrated in the
diagram.
ELEVATE PUMP VENT
After all hydraulic system components are connected
to the hand pump, check the reservoir oil level. Replace the cap and be sure it is closed (not in the
vent position). To purge air from the hydraulic system follow the steps below.
1. Turn the pump release valve to closed position. Operate hand pump until cylinder plunger is
completed extended.
2. Invert cylinder (plunger end down). Open the pump release valve, as the plunger retracts, the
air in the system will be forced into the pump reservoir and replaced by oil. Close the release valve.
3. Turn the cylinder upright. Operate the pump to cycle the cylinder plunger. If air is out of the
system, the plunger will advance and retract smoothly. If the plunger is erratic repeat steps 1
through 4.
4. Open the pump fill cap and check the oil level. Fill to the indicator mark on the end cap.

Maintenance
How To Check The Hydraulic System Oil Level
1. To check oil level in the pump, open pump release valve to allow the oil in the cylinder to return
to the pump.
2. Remove the fill cap.
3. Add hydraulic oil until level with mark on the rear cap. DO NOT overfill.
• To function properly all hand pumps require air in the reservoir.
• If oil level is too high the pump will not operate. Fill only to level indicated on the pump.
• Over-filling the reservoir may cause the pump to malfunction.
• Fill the reservoir only when all cylinders have been retracted. If you add oil when the cylinder is
extended, the reservoir will overflow or be pressurized when you retract the cylinder.
4. If hydraulic system is used under extremely dirty conditions, frequently drain pump completely
and refill with clean hydraulic oil.

1. Keep the components clean at all times.
2. Keep the pump and couplings as free from dust and dirt as possible. Uses only approved
hydraulic fluid and change the hydraulic fluid often if used in extreme conditions.
3. Store system in an area where temperatures are between 10-24° C (50-75° F). Never store
system in direct sunlight or near a heat source.
4. Perform a visual inspection of all components prior to using equipment.
5. Replace worn components with “like-kind” equipment that is rated for the maximum hydraulic
system pressures.
6. DO NOT move the hydraulic system by pulling or lifting on the couplings or hose.
7. Before long term storage, fully extend and retract the plunger once. Then, store the cylinder
upside-down. This will help protect the cylinder from corrosion.

FEED & HOIST CHAINS and SPROCKETS - (20238-000)
General
This topic applies to roller chains with the following part number prefixes: 20238, 21522, 22470,
22737, 22738, and 22739.
A chain is a reliable machine component, which transmits power by means of tensile forces and is
used primarily for power transmission or conveyance systems.
New chain is vacuum lubricated during manufacturing. Lubrication increases chain life by reducing
wear and helping to prevent corrosion damage, primarily to the pins. Regular application of a pene-
trating oil will restore internal lubrication and drive out moisture. Heavy oil or grease provides a bar-
rier to dirt and moisture. The benefits of lubrication outweigh the wear that may occur from abrasion
resulting from dirt picked up by the oil on the chain.
Most samples of chain examined after failure show signs of corrosion on the pins and link plates.
The pitting that results from corrosion establishes points on the pin surface where cracks and
breaks will occur from shock loads or high tensile loads. Lubrication will help prevent corrosion and
premature chain failure.
General Safety Recommendations
Safety for operators and ground personnel is of prime concern. Always take the necessary
precautions to ensure safety to others as well as yourself. To ensure safety, this equipment must be
operated with care and concern by the operator for the equipment and a thorough knowledge of the
machine's performance capabilities. The following recommendations are offered as a general safety
guide. Local rules and regulations will also apply.

tension. The holes for press-fit or bushings are
accurately punched to maintain uniform pitch.
PIN BUSHING
ROLLER
The pin is subject to shearing and bending forces
transmitted by the plate. At the same time, it forms a PIN
load-bearing part, together with the bushing, when the chain flexes during sprocket engagement.
Therefore, the pin needs high tensile and shear strength, resistance to bending, and also must have
sufficient endurance against shock and wear.

Maintenance
Sandvik recommends the following chain and sprocket care procedures:
! DANGER
WARNING
1.When using compressed air to blow chains clean, reduce pressure to 2 bar (30 psi)
and wear a face shield.
2.“Lock-out/tag-out all equipment prior to performing any chain inspection or chain

maintenance procedures
3. Personnel working at heights of greater than 1.83 meters (6 feet) are required to wear a safety
harness and tie off lanyard to prevent an accidental fall.
4. Clean the chains at regularly scheduled intervals. Blow or brush to clean. We do not recom-
mend direct pressure or steam washing because this will remove necessary lubrication.
5. Using a light penetrating oil such as WD-40, brush or spray the cleaned chains. A spray appli-
cation will more effectively penetrate between the rollers and pins.
6. Brush heavy oil on all surfaces after applying the penetrating oil. A 40 weight oil or heavier is
recommended, grease can also be used.
7. Inspect sprocket teeth for wear at regular intervals.
8. Sprocket shafts must be greased regularly. At regular intervals check to verify that sprockets
are receiving proper lubrication and turning freely.
Service Intervals
Ideally, chain maintenance should be done every 100 hours of operation. A 250 hour service interval
is the longest recommended. More frequent service intervals may be required depending on local
conditions, such as dust, rain, etc. Chain tension should be visually checked daily by the operator.
Chain Inspections
Visual Chain Tension Inspection
Visual inspection of the chain tension should be conduct when the mast is lowered. The distance
between the mast chord and the top of the chain should be observed. The operator should determine
if the chain tension needs to be measured and adjusted.
8-2 Copyright © Sandvik Mining and Construction

Physical Chain Tension Inspection
Inspections to the feed system chains is accomplished as follows:
1. Raise the rotary head to the top of the mast.
2. Unlock and lower the mast to the mast rest (horizontal position).
3. Tag-out the cab to inform others of the servicing in progress.
4. Measurements of the feed chain sag must be made midway between mast table and rotary
head, and from the bottom edge of the mast chord to the top of the feed chain as shown.
5. If the chain tension is not set to proper specifications, perform chain adjustments as per O&M
manual instructions.
ROTARY HEAD AT
MAST MAST TOP OF STROKE
TABLE CHORD ‘B’ ‘A’ ‘B’
MEASURING FEED CHAIN SAG
The general rule for chain sag measurement is as follows. The chain sag should be adjusted to
within 1% of the distance from the sprocket to the rotary head. Example: If the distance from the
sprocket to rotary head (at the top of the mast) is 13.7 meters (45 feet), then the sag measurement
distance calculation is as follows.
13.7 meters (45 feet) x 0.01 = 13.7 cm (5.4 in.)

A = 13.7 cm (5.4 in.) sag at center of mast when not equipped with a drill pipe stabilizer assembly.
B = 6.85 mm (2.7") sag at 1/3 length from table and 1/3 length from crown of mast when equipped
with a drill pipe stabilizer assembly.

Chain Wear Inspection
Inspect the chain for cracks, broken, deformed, or corroded parts; and for
tight joints or turned pins. If any are found, find and correct the cause of
the damage, and REPLACE THE ENTIRE CHAIN. Even though the rest
of the chain appears to be in good condition, it has been damaged and
more failures are likely to occur. The upper diagram to the right shows a
link plate with shaded areas indicating areas where stress occurs and the
lower diagram an example of crack in a link plate.
In most roller chain drives, the chain is considered worn out when it has
reached 3% wear elongation. With 3% wear, the chain does not engage
the sprocket properly and can cause sprocket damage or chain breakage.
On drives with large sprockets (more than 66 teeth), allowable wear is limited to 200/N (N = no. of
teeth on largest sprocket) and may be substantially less than 3%. On fixed-center, nonadjustable
drives, allowable wear elongation is limited to about one-half of one chain pitch.
Measure a representative section of chain and if wear elongation exceeds 3% or the functional
limit, REPLACE THE ENTIRE CHAIN. Do not connect a new section of chain to a worn section.
Sprocket Inspection
Inspect sprockets for chipped, broken, or deformed teeth. If any are found, find and correct the
cause of the damage and REPLACE THE SPROCKET. Sprockets normally are stronger and less
sensitive to damage than chains, but running a worn chain on new sprockets can ruin the sprockets
in a short time. This is because a worn chain rides very high on the sprocket teeth and wears the
sprocket teeth in an abnormal pattern.
The bottom sprockets are particularly susceptible to wear because drilling dirt can accumulate
around them. When the bottom radius between the teeth wears and deepens, the teeth actually
form a wedge that can put tremendous force on the pins and rollers as they travel over the sprocket
under load. Sprockets should be inspected and if worn, replaced when the chain is replaced.
A worn sprocket is not nearly as well defined as a worn chain. However, there are some sprocket
characteristics that indicate when a sprocket should be replaced. Check for roughness or binding
when a new chain engages or disengages the sprocket. Inspect for reduced tooth thickness and
hooked tooth tips. If any of these conditions are present, the sprocket teeth are excessively worn
and the sprocket should be replaced.
As the sprocket turns and roller progress from surface “A” to “B”,
power is transmitted to the roller, advancing the chain. When the
roller reaches “C”, the sprocket is no longer transmitting power,
but is guiding the chain. If the sprocket material from “A” to “C” is
worn or broken then sprocket must be replaced.

The diagram to the right depicts a sprocket with shaded areas

indicating “wear patterns”. Wear slightly above the tooth trough
at “A” indicates normal wear with proper chain tension. If the
chain tension is slack, wear indication will be observed at “B”.
Do not run new chain on worn out sprockets because it can

WORN SPROCKET
cause the chain to wear rapidly. The pitch of the new chain is MATERIAL
much shorter than the effective pitch of the worn sprocket, so
the total chain load is concentrated on the final sprocket tooth
before disengagement. Then, when the chain disengages from
the sprocket, the roller is jerked out of the hooked portion of the
sprocket tooth and that results in a shock load on the chain as
the load is transferred from one tooth to the next.

WATER INJECTION PUMP - 002168-001
Safety
! WARNING
Many accidents occur every year through careless use of mechanical
equipment. You can avoid hazards associated with high pressure
equipment by always following the safety precautions listed below.
• SHUT DOWN OR DISENGAGE the pump and all accessory equipment before attempting any
type of service. Failure to do this could cause electrical shock or injury from moving pump parts
or components under high pressure. Always adhere to “Lock Out” and “Tag Out” procedures.
For mobile equipment, be sure engines and hydraulics cannot be accidentally started.
• BLEED OFF ALL PRESSURE to the pump and piping before performing any maintenance on
the pump. Failure to do so may spray water at high pressure or high temperature onto service
personnel.
• NEVER OPERATE THE PUMP WITHOUT A PRESSURE RELIEF VALVE, rupture disc, or
other type of properly sized over pressure safety device installed.
• ALWAYS USE A PRESSURE GAGE when operating the pump. The pressure must never
exceed the maximum pressure rating of the pump or damage may occur. This damage can
cause leakage or structural damage resulting in injury to personnel.
• ENSURE THAT NO VALVES ARE PLACED BETWEEN THE PUMP AND PRESSURE
RELIEF VALVE. If the pump is started with a closed or restricted valve in line before the pres-
sure relief valve, the pump may exceed the rated or design pressure limits and rupture causing
injury to personnel.
• ALWAYS USE GUARDS on all belt drives, couplings, and shafts. Guards can prevent person-
nel from becoming entangled and injured by rotating and reciprocating parts.
• USE EXTREME CAUTION WITH SOLVENTS used to clean or degrease equipment. Most sol-
vents are highly flammable and toxic. Observe all safety instructions on packaging.
• FOLLOW NORMAL ENVIRONMENTAL GUIDELINES WHEN fluids, lubricants, or solvents are

disposed of or spilled.
• NEVER MODIFY THE PUMP to perform beyond its rated specifications without proper authori-
zation in writing.

Storage
Short Term Storage

If the pump is stored in an indoor, temperature controlled
environment for less than six (6) months, no special steps are
required to prepare it for storage. As a general rule for pumps in
corrosive fluid applications, the fluid end should be drained,
flushed with water or other non-corrosive cleanser and
compressed air used to blow dry whenever idle.
Short Term Storage for Severe Environments

If the pump has been in service, drain any fluid from pump fluid
end, flush the fluid end with water to clean out any of the
remaining pumpage and blow dry with compressed air. Pour 1/4
cup of internal rust inhibitor oil described in the Recommended
Lubricant Chart, into the suction and discharge ports of fluid end,
and then install pipe plugs in openings. Drain the power end
(crankcase) oil and remove the oil fill pipe plug. Pour 1/4 to 1/2 cup of internal rust inhibitor oil
described in the Recommended Lubricant Chart, into the oil fill hole and then install the filler pipe
plug.
Coat all exposed, unpainted metal surfaces (for example, Drive shaft) with preservative oil. Replace
the oil fill cap, and then cover the entire pump with a weather resistant covering such as a canvas
or plastic tarp or bag.
Returning a Stored Pump to Operation

Before operating a pump that has been prepared for storage, drain the preservative and
lubricating oil mixture from the power end (crankcase). Reinstall the drain plug, filler pipe plug, and
any other components that were removed for storage. Once these steps have been completed,
follow the normal pump start up procedures outlined in this manual.
Precautions during Freezing Weather

Freezing weather can cause problems for equipment when pumping water-based fluids that expand
in volume when changing from a liquid to a frozen solid state. When water is left in a pump fluid end
and exposed to freezing temperatures, the expansion of the water as it freezes can rupture the fluid
cylinder or ceramic cylinders of the pump and cause equipment damage. Injury may result when
starting equipment that has been damaged.
Whenever the pump is stored or idle in conditions that are near or below freezing, any water based
fluids should be removed from the pump. The best way to do this is to run the pump for a few
seconds with the suction and discharge lines disconnected or open to atmosphere. This will clear
the majority of the fluid from the pumping chamber as well as the suction and discharge manifolds.
After the run, blow compressed air through the fluid end to remove all traces of fluid.
As an alternative to the previous procedure, a compatible antifreeze solution can be circulated

through the fluid end. RV antifreeze, propylene glycol, is recommended for this purpose. Remember
that any fluid that poses an environmental hazard or is toxic must be handled and disposed of
properly.

How to Start a Pump
NOTICE
Always take special precautions when starting a pump for the first time or after any extended
shutdown. Never assume that someone else has properly prepared the pump and system for
operation. Always check each component of the system prior to every start-up.
1. Ensure that the drain plug on the bottom of the pump crankcase is installed.
2. Check the oil level to ensure that the pump is properly filled with 1 quart (0.95 liters) of non-
detergent motor oil, gear lube, or a synthetic oil as described in the Recommended Lubricants
Chart, and that the oil has not been contaminated with water or other contaminants.
3. If accessible, check the piston rods to ensure that they are free from abrasive particles or
debris.
4. Ensure that the pressure relief valve and all accessory equipment have been installed and
properly adjusted. Verify that all joints are pressure tight.
5. Open the suction line valve to allow fluid to enter pump. Prime the fluid cylinder if necessary on
the initial start up or after the system piping has been drained. The valve covers may have to be
cracked open to assist with priming.
6. Check to ensure that power is locked out and tagged out. Turn the pump over by hand if possi-
ble to ensure free, unobstructed operation.
7. Make sure that all guards are in place and secure. Verify that all personnel are in safe positions
and that system conditions are acceptable for operation.
8. The pump is now ready to start. Shut down immediately if the flow becomes unsteady, pressure
fluctuates, or if unusual sounds or vibrations are noted.
9. Take temperature readings of the power end and stuffing boxes. Do not exceed 170°F (77°C)
on power end.

Inspection and Preventative Maintenance Chart

Routine maintenance is an essential part of any successful pump installation. Properly maintained
water injection pumps are designed to offer years of trouble-free service.
Regular maintenance and inspection will keep your pump operating at peak performance. This
pump has been carefully engineered to minimize maintenance requirements and simplify these
tasks when they are required. Regular inspections allow operators to become familiar with normal
pump operation so they can recognize the signals of potential problems and schedule mainte-
nance. The maintenance chart below should be used as a guideline only. Many applications will
require adjustment of the intervals shown in this chart for severe or unusual operating conditions.

Component Parts List
A typical pump configuration is shown below for general reference purposes. This will aid in
identifying components for service procedures outlined in the following sections. To order service
parts refer to the machine Parts Manual.


Service Procedures
The following sections illustrate step-by-step instructions for performing most common service
procedures of a pump. Read each section before starting service work on the pump. Refer to your
machine parts manual for component identification.
Replacing Cup Pistons
! WARNING
Ensure that all pressure inside the pump fluid cylinder has been bled off
before starting any service work. Lock-out and tag-out the starting
components.
1. Bleed off all pressure and ensure the pump power supply is off and is disconnected (Locked and
Tagged out, if applicable).
2. Remove the fluid cylinder (38) from pump by removing the
three capscrews (39) holding it to the power frame, then lift the
fluid cylinder off the top of the ceramic cylinders (42).
3. Remove the ring seals (41) and O-rings (40) from the top of
the cylinders or from the counter bores of the fluid cylinder.
4. Remove the capscrew (44) and piston cup washer (45) from
each of the two cylinders.
5. Lift the ceramic cylinder (42) off the top of the power frame
(1). Friction will usually keep the piston cup (46) inside the cyl-
inder as it is removed. Once the cylinders and pistons are off
the pump, take them to a bench and press them out from the
top.

6. Remove the piston holder (47) and O-ring (48) from the
crosshead shaft (6).
7. Inspect all O-rings, gaskets, seals, and other components for
signs of damage or wear. Any damaged components should be
replaced at this time. Inspect the ceramic cylinders for cracks
or grooves by visual inspection and running thumbnail around
the bore of the cylinder. Replace if grooves or cracks are
detected. New piston cups will wear quickly if operated in cylin-
ders with rough or grooved bores. NOTE! To provide maxi-
mum operational time between service, it is recommended that
both piston cups, not just the one that shows signs of leakage, be replaced whenever piston service
is required.
8. Ensure that the umbrella fluid shield (50) is not damaged. A damaged umbrella could allow fluid
to contaminate the power end oil. If the umbrella requires replacement, the best way to remove it
from the pump is to cut it free with a sharp knife.
NOTE! It is recommended that all associated gaskets or O-rings be replaced at each piston cup
service interval.
9. If new umbrellas (50) are required, fold the plastic as shown
and insert through the opening of the crosshead bore of the
power frame, and over the ends of the crosshead shaft. For
easier installation of the umbrella, immerse in boiling water for
2-3 minutes to soften. Use caution to avoid burns or scalding
when working with hot water.
10. Once the umbrellas are installed over the crosshead shaft,
lift them up slightly and insert the umbrella washers (49) through
the upper opening of the umbrella. Ensure the groove of the
washer is facing up.

11. Place O-rings (48) and piston holders (47) in position
on ends of crosshead shaft.
12. Place ceramic cylinders (42) and gaskets (43) in coun-
ter bore of power frame (1).
13. Apply light oil or glycerin around the OD of the piston
cups (46), then place them in the open end of the cylinders.
Use thumb to press the cups down firmly into the piston
holder of each cylinder.
14. Insert the piston cup washers (45) into the cylinders
with the ribbed side facing the piston cup.
15. Secure packing assembly using capscrews (44).

Torque to specification per the Fastener Torque Require-
ments table.
16. Insert top O-ring (40) and ring seal (41) in fluid cylnder
counter bore using heavy oil or grease to hold in place.
17. Return fluid cylinder (38) to position over cylinders (42)
and ensure that all seals are in place.
18. Replace fluid end capscrews (39). Torque capscrews in
3 stages to values shown in the Fastener Torque Require-
ments table.
Replacing Suction and Discharge Valves
1. Remove capscrew (58) and valve cover clamp

(57) from the front of the fluid cylinder (38).

2. Insert the end of a standard screwdriver into the

valve cover (56) groove and pry the valve cover
away from the fluid cylinder (38).
3. Remove the valve cage (55) and discharge

valve disc-spring assembly (53, 54) from both
bores of the fluid cylinder (38).
4. Use a finger to reach through the opening at the

center of the seat (51) and work the seat loose from the
fluid cylinder bore. NOTE! The optional Valve Seat
Removal tool (see figure below) may be used to simplify
this procedure.
5. Use the same procedure to remove the suction valve
cage (55), valve disc-spring (53, 54), and valve seat
(51), which are located directly under the discharge
valve seat.
6. Inspect all valve components and replace as neces-
sary. Note that even small damage or erosion to the
sealing area of the valve or the O-ring can adversely
affect the performance of the pump.
7. With the O-ring (52) in place on each valve seat (51),
place a few drops of light oil around the O-ring to aid in installation. Place a valve seat SQUARELY
in the back of both counter bores of the fluid cylinder.
8. Place the valve cage (55) on the valve seat (51) and insert the disc-spring assembly (53, 54)
inside of the cage on the valve seat.
9. Repeat the previous two steps to install the discharge valve seat and the discharge valve cage.
10. Place the valve covers (56), with O-rings (52) on the BOTTOM groove in place over the valve
assembly.

11. Replace valve cover clamp (57) and capscrew (58) and torque to specification per the Fastener
Torque Requirements table. NOTE! Over-tightening of the capscrew can damage the valve compo-
nents.
Valve Seat Removal Tool
Servicing the Power End
1. Remove bottom drain pipe plug (17) and drain all oil from power frame.
2. Disconnect suction and discharge piping, power source, and remove pump from mounting base.
3. Although it is not required, it is easier to remove the crankshaft (2) if the fluid end and pistons
have been removed. To remove the fluid end, follow steps 1-4 from the Replacing Cup Piston sec-
tion.
4. Remove the six hex head capscrews (14), washers (15), and mounting base (9) from rear of
pump. When removing the mounting base from the pump, be careful not to damage oil seal gasket
(10) as the mounting base is broken loose.
5. Remove capscrews (16) from the connecting rod assemblies (3) and take out the back half of the
connecting rod shell bearing (4).
NOTE! Connecting rod halves are not interchangeable and must be reassembled in their original
positions. Note the orientation of the machine markings on the connecting rod and cap.

6. Remove the oil slinger (25) from the crankshaft (2). (this model only)
7. Push the connecting rods (3) and crosshead assemblies (6) as far forward into the power frame
as possible to provide clearance for the crankshaft.
8. Once the crankshaft is clear of the connecting rods, remove forward half of the split connecting
rod bearing.
9. Use snap ring pliers to remove the crankshaft
retainer snap ring (13) from each side of the pump.
10. Using a hammer and wood block or rubber mallet,

drive the crank shaft (2) and bearings (12) out either
side of the power frame.
11. If bearing replacement is required, remove bearings from crankshaft using a press. Be sure to
provide suitable support for the back side of the bearings during this step. NOTE! Never pound
directly on the bearings or they may be damaged.
12. Once the crankshaft has been removed, the connecting rods and crossheads can be pulled
from the back of the power frame opening.

13. The wrist pin (5) is a slip fit through the connecting
rod (3) and crosshead (6). Check for signs of wear on
the pin and connecting rod bushing. For critical clear-
ance dimensions, see the Critical Clearance. Replace
the pin if noticeable wear is found. The complete con-
necting rod assembly must be replaced if the bushing is
worn, as the wrist pin bushing is not field replaceable.
14. The split crankshaft shell bearings (4) should be

replaced by inserting new half bearings in the connecting
rod as shown.
15. When re-assembling the crossheads, wrist pins, con-

necting rods, and shell bearings, ensure that they are
assembled in their exact former orientation and position.
16. Carefully clean and inspect all parts. Replace worn or
damaged components as necessary.
17. Install the crosshead and connecting rod assemblies
to their original position in the power frame.
18. Install crankshaft with bearings into the power frame.
19. Place the oil seals (11) over the ends of the crankshaft with the lip of the seals facing the inside
of the power frame.
20. Seat the snap rings (13) in the grooves in the bearing housing against the oil seals and tap the
crankshaft to allow a SLIGHT end play in the crankshaft.
21. Reassemble the connecting rods and shell bearings around the crankshaft. The connecting rod
and cap are a matched set. Be sure to properly match the connecting rods and caps back into their
original position and orientation. Torque connecting rod bolts per the fastener torque requirements
in the Fastener Torque Requirements table.
22. Complete the reassembly by reversing steps 1-8. Torque back cover capscrews (14) per the
fastener torque requirements in the Fastener Torque Requirements table.
23. Re-install the drain pipe plug (17) to the back cover.
24. Refill the power frame with oil, and turn the shaft over several revolutions by hand. When piston
cups are not installed the pump shaft should rotate freely. See instructions in the How to Start
Pump section for oil type and filling directions.
NOTE! This pump require 1 quart (0.95 liters) of oil.

Glossary of Commonly Used Terms
CAPACITY The total volume throughput per unit of time at suction conditions. It includes both liquid
and any dissolved or entrained gases. For all practical purposes this can be considered the volume
flow rate in the suction pipe. The standard unit of pump capacity is U.S. gallons per minute (GPM)
and metric cubic meters per hour (m3/hr).
CAVITATION The state where fluid pressure drops below vapor pressure, causing the liquid to
begin to change from a liquid to a gas and boil. Usually occurs in the chamber between the suction
and discharge valves during the suction stroke, and often sounds like a mechanical knock. Cavita-
tion results in the formation of gas bubbles, or cavities, in the fluid that cause vibration and damage
to components when they collapse.
DAMPENER A device that reduces pressure pulsations in the suction or discharge piping. This
may be referred to as a suction stabilizer, accumulator, or surge suppressor.
DISPLACEMENT The volume swept by all pistons or plungers per unit time. This term is typically
expressed as gallons per revolution.
FLOODED SUCTION Implies that the level of liquid in the suction vessel is above the centerline of
the suction port of the pump.
FLUID END The portion of the pump that converts the linear motion supplied by the power end into
fluid flow at pressure. This may also be called the Liquid End. It is called a valve chamber in old lit-
erature.
MECHANICAL EFFICIENCY Mechanical efficiency (ME) is the ratio, expressed as a percentage,
of pump power output to the pump power input. The mechanical efficiency of reciprocating pumps
is very high, typically 85% to 90%.
NPSHA An abbreviation that stands for Net Positive Suction Head Available. NPSHA is the total
suction pressure, including allowance for acceleration head, available from the system at the pump
suction connection, minus the vapor pressure of the liquid at actual pumping temperature. NPSHA
for a reciprocating pump is normally expressed in units of feet of water.
NPSHR An abbreviation that stands for “Net Positive Suction Head Required”. This is the minimum
total inlet pressure required by the pump for proper operation. This value is a function of pump
design and speed and is determined by the pump manufacturer through a specific NPSH test.
NPSHA should exceed NPSHR by at least 1.5 meters.
PISTON A type of power pump that uses a cylindrical seal (piston) mounted on a holder to drive
fluid through the valves. The piston seal reciprocates within a stationary cylinder.
POWER END The portion of the pump that converts supplied rotary motion into linear motion used
by the Fluid End to move the pumpage.
POWER FRAME The major portion of a power pump that encloses and supports all other compo-
nents of the power (or drive) end. It is called a pump case in old literature.
POWER PUMP A reciprocating pump that drives the pumping element(s) using a slider crank
mechanism. Power pumps are piston, plunger, or diaphragm type. All require a driver with a rotat-
ing shaft, such as a motor or engine, as a power source.
PUMP VALVE A check valve that allows flow of liquid in one direction. The pumps have a series of
two valves, one suction (inlet) and one discharge, per pumping cylinder.
STROKE LENGTH The length of one complete, unidirectional motion of the piston or plunger.
Stroke length is usually expressed in inches.
VOLUMETRIC EFFICIENCY Volumetric efficiency (VE) is the ratio of actual pump capacity output
to theoretical displacement. The volumetric efficiency is affected by the fluid being pumped and the
discharge pressure.

The following switch ratings are based on new component parts. The normal contact position is
without fluid, temperature or pressure. Refer to DMS - DIP switch positions relative to run mode.
1. Level sensors are normal open NO without fluid, close with fluid.
2. Temperature switches are normal closed NC and open with increasing temperature above
the specific rate.
3. Pressure switches are normal open NO and close with pressure above the specific rate, low
pressure allows switch to open.

OHM’S LAW and ELECTRICAL CIRCUITS
Ohms Law
Ohms law expresses the relationship between the current (I), the voltage (E), and the resistance (R)
in a circuit. Ohms law can be expressed in three different ways and can be applied to the entire cir-
cuit or to any part of a circuit. When any two factors are known the third unknown factor can be cal-
culated from Ohms law.
I= E AMPERES = VOLTS
OHMS
R
E = IR VOLTS = AMPERES X OHMS
R= E OHMS = VOLTS
I AMPERES
Ohms law is factored into the design of electrical and electronic systems. Specific components are
selected to meet the design essentials to make the components last for hours of maintenance free
operation.

FUNDAMENTALS OF CURRENT
Electrical current is the flow, or movement of
ELECTRICITY electrons. This movement can be compared to
the flow of water through a pipe. Without pres-
sure (voltage) the current will not flow. Electrical
GENERAL current is measured in amperes or “amps”.
Basic electrical terms mentioned in the Driltech

training module are common to the industry.
DESCRIPTION
The following terms apply to basic electric sys-

tems.
• VOLTAGE
• ELECTRONS
• RESISTANCE
• OHMS CURRENT = ELECTRON FLOW
• CURRENT
• AMPERES
RESISTANCE
Resistance is simply a restriction of current flow.
The following terms are common electrical sys-

VOLTAGE
Voltage provides the electrical pressure, or
force that causes the current or electrons to
flow. The voltage is the difference in electrical
pressure between two points in a circuit. Electri-
cal voltage is measured in “volts”.
VOLTAGE = ELECTRICAL PRESSURE

cycles and temperature.
VOLTMETER
The voltmeter is used to measure the electrical
- pressure in the circuit. Analog and digital mod-
els are available. It is suggested to use the digi-
tal type.
In a DC circuit voltmeters are always connected

+ across (in parallel with) a part of the circuit.
TEST EQUIPMENT
The use of test meters is an invaluable and
essential aid in diagnosing troubles in an electri- VM
cal circuit. If values of voltage, current and
resistance are not measured with suitable test
meters, only a guess can be made as to what
type of defect exist in the circuit.
VOLTMETER
Voltmeters measure the difference in electrical

potential or pressure between the points where
the voltmeter leads are attached. Typical leads
are red for positive (+) and black for negative (-)
polarity.
Common 24 volt systems may read (0 - 32)

volts.
Common 12 volt systems may read (0 - 16)

volts.
AMMETER
The ammeter is used to measure the amount of
current flow. It is suggested to use a digital type
ammeter.
Ammeters generally require opening the circuit

so the ammeter can be connected in series to
measure the current flow.
Page 8
Coil Testing
When testing the coil resistance take note of the

AM meter reading. In Ohm mode a good coil will
register some reading such as 40 ohm as
shown by this meter. If the meter reading indi-
cates OL or some number less than the coil
spec a new coil is in order.
AMMETER
In a DC circuit amps and milliampere are two

common circuit flows.
OHMMETER
The ohmmeter is used to measure resistance in
the circuit.
Ohmmeters are connected across the unit or

portion of the circuit of which the resistance is to
be measured.
The ohmmeter has it’s own power source, usu-

ally a small battery or fuse which forces current
through the circuit to be measured. Make certain that the socket connector is
sealed from contaminants and the contact ter-

tent control.
Battery Specific Gravity Test
This test is performed with a hydrometer, which

is the most accurate hand held tool for deter-
mining the state of charge of a lead acid battery.
Fundamentals of Electricity Page 9

1. Draw electrolyte into the hydrometer a few
times so that the float reaches the same
temperature as the electrolyte. This will
increase the accuracy of your readings.
2. Hold the hydrometer vertically so that the

float is free and does not touch the inner
walls of the barrel.
3. Hold the hydrometer so that the liquid is

level in the barrel and at eye level.
4. When you draw the electrolyte, make sure

that the hydrometer is full.
5. Check each individual battery cell. If the spe-

cific gravity varies more than .050 or "50
points" among the cells while the battery is
at a 75% state of charge or above, then the
battery is bad and should be replaced. The
cells that have a specific gravity of 50 points
less than the highest cell are bad cells. A
hydrometer reading of 1.265 or greater at
80°F indicates a full charge for Interstate
batteries. To determine the battery's state of
charge, compare the hydrometer reading to
the Specific Gravity Chart.
6. To get the most accurate hydrometer read-

ing, you should adjust your hydrometer
reading according to the temperature. If the
electrolyte temperature is ABOVE 80°F ,
ADD .004 (called "four points") to the
hydrometer reading for each 10 degrees
above 80°F. If the electrolyte temperature is
BELOW 80°F, SUBTRACT four points from
the hydrometer reading for each 10 degrees
below 80°F.
