Section 3: WORK PROCEDURE

3.1 Pinionshaft Assembly Removal from Bottom Shell


▪ Remove the floating drive shaft assembly between the crusher and motor.
▪ Drain the oil by removing drain pipe plug (3341-6) and dispose in accordance with site waste
disposal procedure. See Figure 1. Approx. 3.1 quarts (2.9 liters) of oil is in the pinionshaft
housing.
▪ Disconnect the hose assemblies to the oil sight gauge at the pinionshaft housing.

WARNING
Oil products present environmental and fire risks and can cause injury if inhaled or brought
into contact with the skin. Follow your lubricant suppliers instructions and safety directions
when handling oil and greases.

▪ Remove the nuts from the flange on the pinionshaft housing that holds the assembly in the
bottom shell. Mark the position of the pinionshaft adjusting jackscrews and back off the top
jackscrews.
▪ Use the two square head withdrawal bolts provided in the flange of the pinionshaft housing
to remove the assembly from the fit in the bottom shell opening.
▪ Install eyebolt in the threaded hole on top of the pinionshaft housing, attach sling and apply
slight lifting pressure to the assembly.
▪ Place a counterbalance over the end of the pinionshaft assembly and apply hand pressure
to balance the pinionshaft assembly while sliding it out of the crusher. Once the pinionshaft
assembly is about two thirds of the way out of the bottom shell a second eyebolt can be
installed to help remove the assembly.
▪ Record thickness of gaskets on bottom shell flange.

▪ With a hammer and screwdriver, drive the lockwasher (3150-0) tang out of the locknut
(3090-2) groove. Unscrew the locknut and remove it and the lockwasher. (NOTE: left-
handed threads.)
▪ On the pinion end, remove the seal plate bolts (3210-0) and washers (3210-4). Remove the
retaining pin (3009-1).
▪ Press the pinionshaft (3505-0) with the pinion end bearing (3070-1), seal plate (3240-1),
pinion (3050-0), and opposite pinion end inner bearing cone (inner race with rollers and
cage) with cone spacer out of the housing (3005-0). The drive end bearing double cup (outer
race) with outer bearing cone will remain in the housing (3005-0). See Figure 2 for typical
setup of pinionshaft removal.

FIGURE 2
▪ Remove the pinion retaining ring (3650-0) and press off the pinion (3050-0) from the shaft.
The pinion is shrunk fit to the shaft with 0.004 to 0.006" (0.10 to 0.15 mm) interference. See
Figure 3 for typical setup of pinion removal.

▪ Remove pinion end seal plate (3190-1) with oil seal (3170-1).
▪ Remove pinion end lockwasher (3160-0) and locknut (3090-1) by first removing the tang
from the locknut groove with a hammer and screwdriver.
▪ Press off bearings (3070-1 & -2). Bearings are shrunk fit to the shaft (0.001 to 0.003" tight)
(0.025 to 0.076 mm).
▪ Remove the double cup (outer race) from the housing (3005-0). Cup is loose fit in the
housing (0.001 to 0.003" loose) (0.025 to 0.076 mm).
▪ Dress the shaft to clean up any burrs or nicks and measure and record shaft diameters.
▪ Clean up all parts, inspect, and replace those that have been damaged or have failed.

3.3 Reassembly of Pinionshaft


▪ Heat the bearing cones to 300 °F (150 °C) in an oil bath or with an induction heater.
Assemble one heated bearing cone onto the pinion end of the pinionshaft. Install a pipe
spacer over the pinionshaft and hold the bearing tightly in place with the locknut until the
bearing has cooled. Note that the locknut thread is a left-hand thread.

NOTICE
Assemble the bearing cone and cup raceways with faces stamped “A” facing the same
direction. Likewise with faces stamped “C”. Cone faces stamped “B” should face each other.

FIGURE 4
▪ Assemble the double cup and cone spacer of the pinion end bearing onto the pinionshaft
(3505-0), checking to make sure face stampings are aligned correctly. Assemble the second
heated bearing cone onto the pinionshaft and clamp the bearing assembly with the locknut
tightly against the shaft shoulder while it cools.

METSO LCS Global Page 9 of 18


Pinion Rebuild
Gyratory Crusher - Superior MK-II 42-65 313-01-01-006
▪ After the pinion end bearing has cooled, remove the locknut. Locate the position of the
counterbored lube hole on the bearing cup (3070-1) and mark it on the outer end face of the
cup. Apply a bead of Loctite 518 Gasket Eliminator to the groove in the face of the locknut
spacer (3090-1) where it will seal on the face of the bearing cone. Assemble the lockwasher
and locknut onto the pinionshaft, clamping the bearing to the shaft shoulder. NOTE:
Locknuts are left-hand threaded and the drive end locknut (3090-2) is longer than the pinion
end locknut (3090-1). Lock the locknut into place by bending a lockwasher tang into a
locknut groove. Wipe off any excess sealant.
▪ With the pinionshaft housing (3005-0) supported horizontally, insert the drive end of the
pinionshaft (3505-0) into the pinion end of the housing until the drive end bearing shoulder of
the pinionshaft extends beyond the pinionshaft housing.
▪ Assemble the drive end bearing, lockwasher, locknut, and sealant in the same manner
described in the above steps.
▪ Insert the pinionshaft into the housing until the drive end bearing shoulder comes to rest
against the seat inside the housing. Insert the drive end seal plate (3190-2) into place and
measure the gap between the seal plate and housing. Add a gasket that is 0.010" (0.25 mm)
thicker than the gap and torque the seal plate with oil seal (3170-2) into place. Torque to
157-166 ft-lbs (116-123 N-m). NOTE: Oil seal (3170-2) should face toward the bearing
(3070-2).
▪ Align counterbored lubricant hole on the pinion end bearing cup with the retaining pin hole of
the housing. Install the retaining pin (3009-1) with Loctite 242 or equivalent. Then secure
pinion end seal plate (3190-1) with oil seal (3170-1) and gasket (3240-1). Torque bolts to
157-166 ft-lbs (116-123 N-m). Locate contaminant discharge port on Protech labyrinth seal
(3170-1) and mark position on face of seal with paint or a grease pencil. Install Protech seal
in seal plate (3190-1), making sure to line up contaminant discharge port with one of the
mounting holes. Then, secure pinion end seal plate (3190-1) with oil seal (3170-1) and
gasket (3240-1). NOTE: Make sure to locate the contaminant discharge port on the Protech
labyrinth seal so that it is pointing down when the pinionshaft assembly is installed in the
crusher.
▪ Place the pinion key (3515-0) into the shaft keyway. Heat the pinion gear with torches,
taking care not to heat the teeth, to 300 °F (150 °C) and then assemble the heated pinion
gear (3050-0) onto the shaft. Promptly insert the retaining ring (3650-0) into place on the
shaft. Use the retaining ring as a locater for the pinion gear by making sure the pinion is
against the retaining ring. The pinion has an interference fit of 0.004" to 0.006" (0.10 to
0.15 mm) with the shaft.
▪ Use the grease fitting at the drive end seal plate to inject enough grease to fill the gap seal
around the locknut spacer to exclude dirt. Do this while rotating the shaft to ensure the
grease is distributed evenly. Use a grease of NLGI No. 2 or No. 3 consistency such as
Mobilux EP2 or equivalent.
▪ Install the pinionshaft half coupling.
▪ If the pinionshaft assembly is going into long term storage, fill the pinionshaft housing with a
preservative oil to prevent corrosion of the pinionshaft and bearings.

METSO LCS Global Page 10 of 18


Pinion Rebuild
Gyratory Crusher - Superior MK-II 42-65 313-01-01-006
3.4 Installation of Pinionshaft
▪ Position a counterbalance on the drive end of the shaft. Place the gaskets (3030-0) on the
bolting flange of the pinionshaft housing.

NOTICE
Always use the original thickness of gaskets with the same pinion and gear. Any change from
the original will change the tooth contact pattern on the pinion and gear.

▪ Install eyebolts in the threaded holes on top of the pinionshaft housing.


▪ Position the pinionshaft assembly in the bottom shell opening. The close clearance fit in the
bottom shell may require some movement of the assembly with the counterbalance to
engage the leads of the fit. As the pinion reaches the gear, it may be necessary to turn the
pinionshaft to engage the teeth of the pinion and gear to complete the entrance.
▪ Draw up the attaching bolts evenly and securely.
▪ Set the proper backlash between gear and pinion as described in the next section. If a new
pinion, gear or eccentric has been installed, check both backlash and tooth contact.
▪ Re-connect the hose assemblies (3341-2) from the oil sight gauge to the pinionshaft
housing. See Figure 5 below.

Sight
gauge Oil level

FIGURE 5
▪ Remove oil fill plug (3575-0) and fill the pinionshaft assembly to the proper oil level
approximately 3.1 quarts (2.9 liters). Lubricant recommendations are found in Section 3.7
▪ Install floating drive shaft assembly. Realign the drive shaft if backlash was readjusted.

3.5 Checking and Adjusting Gear Pinion Mesh


▪ If the eccentric gear or the eccentric wear plate has been replaced, the gear pinion mesh
must be properly set. Apply marking compound (such as Prussian Blue) to the pinion teeth.

METSO LCS Global Page 11 of 18


Pinion Rebuild
Gyratory Crusher - Superior MK-II 42-65 313-01-01-006
▪ Trial check backlash according to the following directions except without removing pinion
side eccentric to bottom shell bushing clearance. Trial backlash should be on the high side
of the range shown.
▪ Turn the pinion to transfer the marking compound from the pinion teeth to the gear.
▪ Lower the eccentric to check the contact pattern. Correct contact pattern is shown in the
sketch below.

FIGURE 6
▪ If pattern on the load side is near the toe, move the pinionshaft inwards, removing gasketing
between the bottom shell and pinionshaft housing, and recheck contact pattern.
▪ If pattern on the load side is near the heel, move the pinionshaft outwards, adding gasketing
between the bottom shell and pinionshaft housing, and recheck contact pattern.
▪ Check and make final adjustments to backlash after establishing the correct contact pattern.
▪ For checking the backlash, first move the eccentric toward the pinion to remove all
clearance between the eccentric and the bottom shell bushing by placing a block of wood in
the crushing chamber on the opposite side of the pinion. If the mainshaft is installed, raise
the mainshaft assembly with the MPS. Applying 50 psi pressure above the level caused by
the static load of the mainshaft assembly should be sufficient to push the combined
mainshaft and eccentric assemblies toward the pinion to remove the clearance.
▪ Use a dial indicator to measure the circumferential movement of the coupling / sheave and
then calculate the backlash using the following formula. The backlash must be in the range
noted in the table below.
Model Gear Type Pinion Pitch Pinion Pitch Plane of Rotation
Diameter Backlash Backlash
42(50)-65 Spiral 15.33 0.051 - 0.061 0.067 - 0.081
(388.6) (1.30 - 1.55) (1.70 - 2.06)
54-74 (75) Spiral 16.0 0.057 - 0.070 0.076 - 0.094
(406.4) (1.45 - 1.78) (1.93 - 2.39)
60-89 Spiral 17.8 0.060 - 0.075 0.083 - 0.104
(452.1) (1.52 - 1.91) (2.11 - 2.64)

METSO LCS Global Page 12 of 18


Pinion Rebuild
Gyratory Crusher - Superior MK-II 42-65 313-01-01-006
▪ CMC (circumferential movement at coupling):
CMC = Backlash in Plane of Rotation x Coupling or Sheave Outside Diameter ÷ Pitch Diameter of Pinion
Example:
54-74 (with a 16.5" coupling outside diameter) 0.076" x 16.5 ÷ 16 = 0.078" minimum
54-74 (with a 16.5" coupling outside diameter) 0.094" x 16.5 ÷ 16 = 0.097" maximum

▪ To adjust the backlash, the pinionshaft assembly is rotated using the jacking screws.
▪ Loosen the bolts which hold the pinionshaft assembly to the bottom shell. Loosen the hex
nuts locking the jacking screws. Adjust the jacking screws. Clockwise rotation will cause the
pinion gear to move downwards, towards the eccentric gear, reducing backlash.
Counterclockwise rotation will cause the pinion gear to move away from the eccentric gear,
increasing backlash. Lock the jacking screws with the hex nuts, tighten the pinionshaft
assembly bolts, and remeasure backlash.
