Maintenance, Overhaul & Test Instructions
Eatons Carter Brand Model 60554 Hydrant Valve

1.0
INTRODUCTION
Note: The various items specified in this manual
are referred to in parenthesis and indicate the
figure number and item number within that figure
where the item appears. Example: Servicing
Valve (4-3) is item 3 found in Figure 4.
This manual furnishes detailed instructions

covering the maintenance and overhaul of
Eatons Carter brand Model 60554 Hydrant
Valve, a family of hydrant valves as described in
a later paragraph. A separate manual covers the
two special versions of the 60554, 60554-2D
(SM60554-2D) and 60554-3D (SM60554-3D).
2.0
EQUIPMENT DESCRIPTION
is designed to mate a flat faced ANSI 150 lb, 4
inch pipe flange. The outer housing material is
available in either of two grades of ductile iron as
explained below.
The Model 60554 family of hydrant valves

starting with serial number 11161 has been
qualified in accordance with the Third Edition of
API 1584. This version of the industry
specification includes the updating of the
Second Edition and combines the requirements
of the Institute of Petroleum Requirements to
arrive at an industry wide specification. The main
thrust of the Third Edition is to cover in more
detail the break-a-way capability of the
combination hydrant valve and coupler to
improve safety on the ramp. Specific tests were
required of the combination of products to prove
that the hydrant valve and couplers met these
requirements. Ask Carter for 3QTR60554 Test
Report for the results of the tests on the Carter
products.
Upper Housing Assembly - functionally

identical on all valves. The standard upper
housing assembly consists of an aluminum base
casting with a replaceable stainless steel coupler
connecting ring. Two grades of ductile iron
material are available as options as noted below.
In addition, the "S" option changes the complete
upper housing to stainless steel. The outlet
connection in all cases is in accordance with API
Bulletin 1584.
Pilot Valve - five different pilot valves are

utilized on all but Option X. Option X is a new
approach used where the major parts of the pilot
valve is contained on a hose mounted unit
further simplifying the in-pit valve. There are two
versions of the new on-hose pilot, air or fuel
operated and air or fuel operated with manual
override.
Older units (serial numbers under 11161) can be

updated to meet the new requirements by using
a kit noted later.
The Model 60554 family of hydrant valves is
manufactured with a choice of five different pilot
valve arrangements, lanyard or air pressure
operation, capable of flowing in the fueling
direction only, or with air pressure operation,
capable of both fueling and defueling operations
and two different dual air/lanyard pilots. The
lanyard operated type valve is also available in
two different grades of ductile iron. All versions
consist of three major sections:
As previously mentioned, valves as options

are available in two different grades of ductile
iron and one is available with a stainless steel
upper housing. One version (60554-3D, not
covered by this manual) utilizes metric threaded
fasteners to attach the Upper and Lower
Housing Assemblies together.
Various options are available to modify the basic
part number to customize the end item to meet
various customers requirements. These options
are explained in detail in paragraph 3.0 below.
Lower Housing Assembly - functionally

identical on the valves that are capable of flow in
the fueling direction only. The "J" option uses a
different assembly. The inlet flange, in all cases,

SAFETY INSTRUCTIONS/PREVENTATIVE MAINTENANCE
4.1
SERVICING VALVE UTILIZATION - The unit

incorporates a servicing control valve
designed to allow the Upper Housing
Assembly and/or the Pilot Valve to be
removed while the inlet of the unit is under
pressure. See caution below.
does not appear to be under pressure proceed

with the next step.
Remove the Screws (2-3 & 2-5) attaching

the Upper Half Assembly (2-6) and Lower Half
Assembly (5-1).
The Lower Housing Assembly consists of a

pressure overbalanced piston assembly that
shuts off the main flow path. The slipper type
seals utilized on the piston are not absolutely
zero leak seals and an increase in leakage
past these seals is anticipated with age. If the
leakage increases too much, the piston will no
longer stay closed. It is therefore recommended
that the hydrant not be maintained by use of the
servicing valve on a regular basis and when it is
used, the following procedure should be followed
to reduce the possibility of a major spillage of
fuel:
CAUTION!
As long as the hydrant system pressure is on
do not attempt to remove the Lower Housing
Assembly (5-1) from the inlet pipe or loosen
the Servicing Valve (4-3).
CAUTION!
It is not recommended that this procedure be
utilized, except in an emergency condition.
The use of this valve does pose a possible
hazard if not correctly accomplished and the
valve is not in good working order.
If an inlet butterfly valve is available, close it to
reduce the inlet pressure from the hydrant
system.
4.2
HOT HYDRANT - Refer to paragraph 7.1.2 for

the testing procedure to determine whether a
hydrant is hot or not. This preventative
maintenance procedure should be conducted
after one year of service and every six months
thereafter for maximum benefit.
4.3
OUTLET SAFETY INSPECTION - The 60554 is

designed to meet the break a-way requirements
of the 3rd Edition of API 1584. To assure that the
unit will continue to meet these requirements it is
necessary to annually inspect the outlet
configuration to assure that it meets the
dimensions that allows it to be within
specification.
WEAR GAUGE NOW AVAILABLE!
Close the Servicing Valve (4-3) securely, by

hand. The seal on this valve could be damaged
if a wrench is utilized. No threads on the Stem
(4-3) should be visible when the valve is fully
seated.
A new gauge to check the wear on the outlet

connection of the 60554 is now available as
part number 60554ST1. It is a no-go gauge
in that it checks the two critical surfaces of the
API interface for non-conformance to API 1584
and safe usage with any Carter coupler.
Manually depress the pressure Equalization

Poppet (2-13) and allow the pressure inside the
Upper Housing Assembly (2-6) to bleed. If the
flow from the Equalization Poppet (2-13)
reduces to a matter of leakage as differentiated
from continuous flow under pressure, it is safe to
proceed.
The gauge is shown in Figure A below.
CAUTION!
If the flow from the Equalization Poppet (2-13)
is steady and under pressure, do not continue
to remove the Upper Housing Assembly (2-6).
Figure A 60554ST1 Wear Gauge

The gauge has two sides, A to check the outer
diameter and B to check the angular underside
wear surface of the outlet configuration. This
gauge is meant to determine whether the outlet
will continue to meet the break a-way
requirements of API 1584 if the mating coupler
is a Carter unit and it is also within the wear
tolerance of it wear gauge 61362. See the
appropriate Coupler manual for instructions on
how to use the 61362.
On all but Option X - Remove the Pilot

Valve (1-D, 1-E, 1-F, 1-J or 1-U) and wait for at
least one minute while checking the leakage out
of the hole from which the Pilot Valve (1-D, 1-E,
1-F, 1-J or 1-U) or the quick disconnect was
mounted. If the leakage does not appear to be
under pressure proceed with the next step.
On Option X Use a diameter plastic

rod to depress the valve stem located within the
quick disconnect fitting and wait for at least one
minute while checking for leakage. If the leakage

The
operation of the Hydrant Valve,
whether the pilot is lanyard, air
operated or new Option X is
identical.

Figure B reflects the same

hydrant valve with the air pilot in
a closed position.
The only
differences between the two
units are in the operating
mechanism that supplies the
power to open and close the
pilot valve. In the air operated
pilot, the closing lanyard and
opening latching mechanisms are
replaced with an air operated
piston.
When Option X is
present the air pilot is separated
with the piston operator as a
part on the hose to the valve.

Servicing Valve Closed

Pilot Valve Open or Closed
Pilot Valve Closed

Servicing Valve Open
The closing of the Servicing Valve (4-3) has the same

affect as closing the Pilot Valve (1-D, 1-E, 1-F or 1-J).
That is, the flow passage from the piston chamber to
the downstream side of the piston is blocked. The
piston chamber pressure begins to equalize to the inlet
pressure (P1) through the check valve. The piston area
is greater than the effective seal area, hence the
unbalance of forces caused by the equal pressure, plus
the spring, will cause the valve to stay closed.
Pulling the lanyard, or depleting the air supplied to their

respective pilots, will allow the spring loaded pilot
poppet to close. (Depleting the air supply can be
accomplished by activating the deadman control or in
the case of an Air/Lanyard Pilot pulling the lanyard will
release the air pressure. The lanyard is meant for an
emergency closure only and is not meant to be used at
each refueling.) This action blocks off the venting of the
piston chamber to the lower pressure area downstream.
The piston chamber begins to equalize to the inlet
pressure (P1) through the check valve. The piston area
is greater than the effective seal area, hence the
unbalance of forces caused by the equal pressure plus
the spring will cause the piston to begin to close. As the
piston moves toward the closed position, the piston
chamber volume increases and must be filled through
the two series orifices. The primary orifice is
considerably larger than the secondary (slot). During
the initial and majority of the travel of the piston, the
primary orifice is fully exposed to the inlet pressure,
hence the rate of closure is controlled by this orifice.
Pilot Valve Open

Servicing Valve Open
The open pilot valve allows the continuous passageway
from the main piston chamber and from the closing
control orifice. The piston chamber is vented through an
opening control orifice and the open Servicing valve to a
point in the Lower Valve Half. The pressure (P2) at this
point is less than the inlet pressure (P1). The piston
chamber pressure is also maintained at P2 causing an
unbalance of forces on the piston. The inlet pressure
force is greater than the combined piston pressure force
plus the spring force hence the valve will open to allow
flow. This is assuming that the outlet adapter poppet in
the Upper Valve Half has been opened by a Coupler.
When the piston moves far enough closed to cover the

primary orifice, the secondary (smaller) orifice begins to
control the closure rate. Hence the valve begins to close
relatively rapidly and then slows down as it nears its
closed position. The relative size and locations of these
two orifices allows the valve to close to provide a
minimum of overshoot and yet limit the surge pressure
shock, on closing, and still maintain a closure rate in
accordance with applicable international specifications.
The pilot poppet is maintained in the open position by

one of two methods:
Lanyard operated pilot - The pilot is opened by

the pull of the "T" handle located on the top of the pilot
valve. When it is pulled upward, the spring loaded latch
attached to the lanyard pivots to lock the pilot into the
open position.
On "J" Defueling options the pilot valve is manually held

closed by the thumb screw to allow defueling flow.
Pressure supplied to the hydrant valve outlet will cause
the piston to open (as long as the pilot valve is manually
held in the closed position). The overbalance of areas
between the outer diameter of the piston versus the
main piston seal area caused the outlet pressure to
open the piston to allow defueling flow.
Air or Air/Lanyard operated pilot - Air pressure

applied to the pilot piston will maintain the pilot in the
open position until the pressure has been depleted (by
release of deadman).
6.0
DISASSEMBLY
This disassembly procedure assumes that
the valve is located within a shop area where
there is the capability of supplying the
necessary tools. It is also assumed that
options G, P or H are not removed from the
pit for maintenance, although the Gasket (111) used between the two parts (Valve and
Spool) should be replaced at each removal
of the unit from the pit. The same goes for
spool pieces used as Options K and L (1-K &
1-L).
Note:
The valve will be full of fuel and provisions for
draining into a safe container should be made
prior to beginning to work on the unit.
6.1
Place the unit in a container sufficiently large

enough to contain a minimum of 5 gallons (19
l) of fuel. Remove the Cover Assy (2-23).
Push the Adapter Poppet (2-11) open and hold
it open with a flexible plastic rod, or another
non-marring item, to allow the unit to drain.
Hint: A scrap 23620 Rod used in Carter
60427 Nozzle is suitable for this job.
6.2
Remove the Servicing Valve (4-3) and set

aside.
6.3
Turn the unit over onto its outlet, being sure to

place it on a surface that will not damage the
outlet surfaces. Grasp the inlet flange and
apply pressure to the Piston (4-18) to push it
open sufficiently to insert a flexible plastic rod
to keep the piston open as with the Adapter
Poppet (2-11) above. Turn the valve over a

few times to allow the trapped fuel to drain.

The rod can then be removed to close the
Piston (4-18).
6.8.2
6.4
Pilot Valve/Pilot Valve Connector Removal
6.4.1
Pilot Valve - Remove Screws (5-29, 6-18, 7-18

or 8-18) and Washers (5-28, 6-19, 7-19 or 819). Grasp the Pilot Valve (1-D, 1-E, 1-F, 1-J or
1-U) and twist back and forth while applying a
force away from the unit to remove the pilot.
While removing the Pilot Valve (1-D, 1-E, 1-F,
1-J or 1-U) be sure to maintain a straight
upward pressure to prevent causing a binding
of the parts contained within the Lower
Housing Assy (4-10). Some of these parts could
be damaged if a binding during disassembly
occurs. Lay the Pilot Valve (1-D, 1-E, 1-F, 1-J
or 1-U) aside for now.
6.4.2
Pilot Valve Connector Assembly (Option X)

Remove the two Screws (9-5) and Washers (96) to remove Connector (9-2). Remove and
discard O-rings (9-3) and (9-4). If it is
necessary to remove the Valve Stem
Assembly (9-7) special tool T221790 will be
needed to unscrew it from the lower housing. If
removed discard O-ring (9-8). If removed the
Stem (9-11) may be replaced by first placing a
small bladed screwdriver into the hole in the
Spring Guide (9-9) and pry the spring guide
from the part. This allows one to remove the
other parts within and to replace the stem if
necessary.
Newer valves may have a 2-piece upper

housing. This is easily determined by the
aluminum (no epoxy coating) cast upper
housing and the stainless steel adapter ring. If
the upper housing is epoxy coated or all
stainless steel no further disassembly is
possible. If it is the 2-piece upper it is not
necessary to disassemble the part farther
unless there is a leak at the joint between the
Ring (3-4) and the Housing (3-2), then the Oring (3-3) must be replaced. Another reason for
further dis-assembly would be to replace the
Ring (3-4) due to severe denting which can
cause leakage when the coupler is attached.
NOTE:
6.5
If the O-ring (3-3) is being replaced it will be

necessary to heat the assembly to 300F (150
C) for at least one-half hour before trying to
remove the Screws (3-5). Trying to remove
them at room temperature may result in
twisting them off due to the use of Locktite to
retain them in place. If the Ring (3-4) is being
replaced then damaging the screws is of no
concern since the ring will be discarded along
with the screws.
Then remove the Screws (3-5) and Washers
(3-6) from the inside of the unit. Carefully pry
the stainless steel Ring (3-4) from the Housing
(3-2). Remove and discard O-ring (3-3).
Remove Screws (2-3 & 2-5) and Washers (24). Note that Screw (2-5) is shorter than
Screws (2-3). It should be noted that it was
installed in the hole to the left of the Pilot Valve
(1-D, 1-E, 1-F, 1-J or 1-U) when facing the unit
with the Pilot Valve (1-D, 1-E, 1-F, 1-J or 1-U)
directly in the center. Note that on newer units
this shorter Screw (2-5) is made of stainless
steel, for ease of identification only, instead of
the normal cadmium plated Screws (2-3).
6.6
Using a thin, wide blade screwdriver, gently pry

the Upper Half Assy (2-6) from the Lower Half
Assy (4-1). Be careful not to damage the
epoxy coating. Remove and discard O-ring (222). Set the Lower Half Assy (4-1) aside.
6.7
Remove Strainer (2-21), if present, from unit.

Set it aside.
6.8
Upper Half Assy (2-6) - Remove the plastic rod

holding the Poppet (2-11) open and install the
Cover Assy (2-23) to protect the Upper Half
Assy (2-6). Turn the unit over onto the Cover
Assy (2-23).
6.8.1
While pushing downward on Poppet Retainer

(2-19), using a thin blade screwdriver, remove
Retainer Ring (2-20) from Upper Housing (27). Slowly release downward pressure on
6.8.3
Using a thin blade screwdriver, carefully pry an

end of the Retaining Ring (2-17) and remove it
from its groove. Disassemble Poppet Assy (2-8)
removing the various parts. Remove Seal Ring
(2-9) from Seal (2-10) and discard Seal (2-10).
Remove and discard Seal (2-12).
6.8.4
If present and the valve is the obsolete style

that utilized bosses cast onto the Upper
Housing (2-7), there is no need to disassemble
the product selection part of the Upper Half
Assy (2-6) unless parts need replacing due to
missing or damaged parts. On newer valves,
these bosses were removed and the product
selection feature is achieved by the addition of
the Product Selection Ring Assy (1-C). This
ring is attached to the unit by using four extra
long Bolts (1-5) and Standoffs (1-2). It is then
necessary to disassemble the Product
Selection Assy (1-C) from the unit during
disassembly of the valve. On older versions of
the newer valves, the Ring (1-1) holding the
product selection studs is a solid one piece
ring. On newer valves the ring is composed of
four equally thick stamped Rings (1-1). The
older units utilize one piece product selection
studs while the newer units utilize standard
Bolts (1-3) and a stack of Washers (1-4 & 1-6).
If replacement of either the older ring or the
SM60554
6.10
studs is required, utilize the newer

replacement parts.
6.9
Lower Half Assy - Turn Lower Half Assy (4-1)

over to expose the inlet flange. Remove
Screws (4-15). Early versions of the unit
utilized only two Screws (4-15) to retain the
Piston Retainer (4-16). The later versions
utilize six. This change was made necessary
on a similar valve, model 61654 with a six inch
ANSI flange. On the model 60554, the Piston
Retainer (4-16) is retained in place by the
mating pipe flange hence the mandatory use of
six screws is not necessary. However, if there
are six present, all six should be replaced.
Note: If Screws (4-15) are difficult to remove,
an impact wrench may be necessary to
prevent damage to the Phillips recesses of the
Screws (4-15). Also note: Normally, the main
Spring (4-26) will be strong enough to force the
Piston Retainer (4-16) out of the unit. If not,
use a thin blade screwdriver to carefully pry
out Piston Retainer (4-16). Remove and
discard O-Ring (4-17).
6.9.1
Remove Piston Assy (4-18 to 4-21), Spring (426), Washer (4-27) and Seal (4-28). Discard
Seal (4-28). Remove Screws (4-19), Seal
Retainer (4-20) and Seal (4-21). Discard Seal
(4-21). Using an o-ring pick, carefully remove
and discard O-Ring (4-22) and Slipper Seal (423) from Piston (4-18).
6.9.2
Using an o-ring pick, carefully remove Piston

Seal (4-25) and O-Ring (4-24) and discard
both.
6.9.3
Using an appropriately sized wide blade

screwdriver, remove the Cage (5-18, 6-2, 7-2
or 8-2) from Lower Housing (4-11) by
unscrewing counter clockwise. Remove and
discard O-Ring (5-1, 6-11, 7-11 or 8-11) from
Cage (5-18, 6-2, 7-2 or 8-2).
6.9.5
It is not necessary to remove the Orifice (4-29)

located in one of the internal holes visible
through the Servicing Valve (4-3) port. Using
shop air pressure, blow air through the
opening to clear the Orifice (4-29). If the air
does not flow easily through the orifice out
through the inner part of the Lower Housing (411), the Orifice (4-29) may be plugged. In that
case, it will be necessary to remove the Orifice
(4-29) and either clean it or replace it.
Operated Pilot Valve (1-E) - In the history of

the 60554 Hydrant Valve there have been
three different Pilot Valves utilized:
Current (1991 & later) production unit, part

number 44721, utilizes the same Housing (6-1)
and Piston (6-14) as is used on the Defueling
Pilot Valve (1-J). A Spacer (6-17) is added on
the Shaft (6-16) between the Housing (6-1)
and the Piston (6-14). The change to this unit
was made to standardize on production parts
between the pilot valves used on both Options
E and J. The only way to tell the obsolete pilot
valve apart from the current production unit is
to disassemble the unit and check for the
presence of the Spacer (6-17) or to look at the
bottom of the Piston (6-14) chamber of the
Housing (6-1). If the chamber bottom is flat
bottomed as opposed to a conical bottomed,
the pilot valve is of current design. If the
bottom is conical, the pilot valve is an old style
44247.
On newer valves (after first quarter 2000)

the Housing (6-1) may be changed to provide
better production economics. The newer
valves may use the housing from the dual
air/lanyard operated pilot valves with a Plug (627) to fill in the extra air port. This also gives
the option to install the air connection in either
of the available ports to move the connection
farther away from possible damage from the
dropping of the coupler onto the valve.
Previous generation Pilot Valve (1-E) - As

mentioned above, this unit has a conical
bottomed piston chamber. The Piston (6-14) is
also different. The older Piston (6-14) will not
work in the newer pilot valve. Should an older
Housing (6-1) be needed for replacement, it will
be necessary to also procure a new Piston (614), Spacer (6-17) and the new Housing (6-1).
Check to see if the Shaft (4-12) is loose in the

Lower Housing (4-11) only, do not attempt to
remove Screw (4-14), Washer (4-13) or Shaft
(4-12) from Lower Housing (4-11). The Shaft
(4-12) is press fitted into the Lower Housing (411) and neither part is available as a
replaceable spare part. If it is necessary to
replace the Shaft (4-12), it is necessary to
replace the Housing Assy (4-10) as a complete
unit.

January 2011
First generation Pilot Valve (1-E) - This

Pilot Valve, part number 42846, utilized some
of the same parts as are currently utilized.
However, there are major differences. One of
these differences can be upgraded to current
production by utilizing kit 2KD42836, provided
the existing Cage (6-2) is still usable. This kit
replaces the fixed pilot seal poppet with a
"floating" design for more reliable operation.
Since the older parts have been out of
production for many years, it may be
necessary to consider replacing the entire Pilot
Valve 42846 with Pilot Valve 44721.
It is not necessary to remove the Air Quick
Disconnect or Fusible Plug (1-M or 1-T if
furnished as such) from the unit unless it is
necessary to replace the unit.

except the following parts are different:
Housing (Obsolete) instead of Housing (6-1)
Piston (Obsolete) instead of Piston (6-14).
6.12
Air Operated Pilot (Defueling type) (1-J) Newer valves (those received after the first
quarter of 2000) may have a different defuel
control screw. The Screw (6-23) was
shortened and made with a larger thread size
to help prevent operators from bending it when
the coupler is dropped onto the hydrant. This
made it necessary also to change the Cover
(6-22) and Pin (6-24) to suit. Ordering any of
the older parts will automatically be entered as
the pre-assembled Screw Assembly (6-21). In
addition the Housing (6-1) was changed to
provide better production economics. The
newer valves may use the housing from the
dual air/lanyard operated pilot valves with a
Plug (6-27) to fill in the extra air port. This also
gives the option to install the air connection in
either of the available ports to move the
connection farther away from possible damage
from the dropping of the coupler onto the
valve.
Push Latch Spool (5-4) to force the Shaft (516) out of Housing (5-2) sufficiently to remove
Pin (5-17). If the pilot latching mechanism
requires servicing, cut the Cable Assy (5-10) or
Clamp (5-15) after removing Hose (5-13) and
Clamp (5-14). Cable Assy (5-10) can then be
pulled back through Latch Bracket (5-9) to
allow removal of Spring (5-12) and Latch Stop
(5-11). If the Latch Bracket (5-9) is to be
replaced, mount Housing (5-2) in a suitably
padded vise and pull Pins (5-8) with pliers.
If necessary to replace parts, using a .187
(4.750 mm) dia. drift pin, remove Pin (5-7)
from Handle (5-6) and Latch Spool (5-4). Note
on older valves the hole in the Handle (5-6) for
this Pin (5-7) is on center. Newer valves have
the hole to one side. Even newer valves have
a ball attached to the Handle (5-6) to prevent
possible interference between the Handle (5-6)
and the mating coupler bumper. Do not try to
remove the ball from the end of the Handle (56) unless it is loose and needs replacing.
The disassembly procedure is the same as in

paragraph 6.10 except for the following
changes and the addition of several parts as
noted:
6.14
Cover Assy (6-21) instead of (6-12).

Additional parts include Defuel Control Screw
(6-23), Pin (6-24), Wave Washers (6-25),
Washers (6-26) between the Wave Washers
(6-25) and Wear Plate (6-20) between the
Piston (6-14) and the screw on the Cover (622). Cover (6-22) need not be disassembled
unless some part is damaged and needs
replacing.

sufficiently to remove Pin (7-4). This allows the
removal of Poppet (7-3). Slide Spring (7-7) off of
Shaft (7-16). Unscrew Adapter (7-5) from Shaft (716). Slide O-Ring Retainer (7-8) off of Shaft (716). Carefully pick out O-Ring (7-9) from Housing
(7-1) and discard. Remove and discard O-Ring (710). Remove Cover (7-12) and Spring (7-13).
Push Piston (7-14) out of Housing (7-1). Remove

(7-16) from Piston (7-14) unless either part is
damaged and must be replaced. Remove and
discard Bal Seal (7-15) from Piston (7-14).
Lanyard Operated Pilot (1-D) - In the history of

the 60554D Lanyard Operated Valve, there have
been two different Lanyard Operated Pilots,
42836 and 44248. These units can be identified
as follows:
The current design unit incorporates a

floating pilot poppet design to provide for more
reliable operation. The Poppet (5-22) has a
bonded on rubber seal. The Cage (5-18) now
used is interchangeable with the older cage. In
addition, when the valves leave the factory, the

air system can occur at any of the air-fuel

interface points. These are normally found in
either the line mounted pressure control valves,
hydrant couplers, float operated water sump
control valves or at the hydrant valve. Some of
these types of components, Carter 60700-1
Hydrant Coupler and 61024 Line Mounted
Pressure Control Valve, can be eliminated from
consideration since they have a vent between the
air to fuel interface. If the fuel seal leaks on these
units, it results in an external leakage out of the
vent point, not into the air system.
The inspections listed in this section should be

conducted on a periodic basis, the frequency of
which should be no less than that mentioned in
each section. The time between testing should be
tailored to fit the particular operation and age of the
system.
7.1.1
Servicing Valve (4-3) - Carefully using a .156

inch (3.960 mm) drift pin, remove Pin (4-7).
Remove Stem (4-6) from Poppet Retainer (48). Remove and discard O-Ring (4-9) and
Gasket (4-2). If Poppet (4-4) does not need
replacement, do not disassemble further. If
necessary, using snap ring pliers, remove Ring
(4-5) to replace Poppet (4-4).
Fuel-in-the-air Check (applicable to all Options

but D and X) - It is recommended that this
inspection procedure be conducted initially on
new units after one year of operating and then
each six months thereafter.
60554E, 60554J, 60554F and 60554U Hydrant

Valves utilize air operated pilot valves with an airto-fuel interface seal that is not vented, hence are
candidates for fuel to the air system leakage with
time.
Air operated hydrant valves are one possible

source of contamination when fuel leaks into the
air systems. (If Option X is being used and there
is fuel leaking into the air system, the culprit may
be in the 64230 or 64231 Pilot located on the
hydrant servicer hose). Many of the standard air
components used within a refueling system are
not necessarily fuel resistant, hence the results
can be costly and time consuming. In addition,
fuel contamination in the air system will quickly be
apparent by the expelling of a fuel mist out of the
exhaust of the deadman valve. This is not a safe
situation around hot jet engines. Air operated
hydrant valves are not the primary source of the
problem, just a possibility. Leakage of fuel into the
Finding fuel in the air pilot's air chamber is not

conclusive that the air pilot is the leakage
source. However, every air pilot that is leaking
will have the symptom of fuel in its operating air
cavity and quick disconnect fitting (if so fitted).
The most obvious evidence that the air pilot is
responsible for air system contamination is
steady flow (or weapage) of fuel emitting from
the quick disconnect fitting that is mounted to the
air pilot. This confirmation will be made possible
11
SM60554
only if the fitting is specifically designed to allow

air to bleed from within the air pilot's air cavity. If
the quick disconnect fitting is full of fuel, but
leakage flow, as described above, is not
obvious, then the following procedure can be
used to confirm that the air pilot is responsible
for the leakage.
Servicing Valve - A mechanical valve

located in series with the Pilot Valve (between
the Inlet Shutoff Valve and the Pilot Valve). It is
designed to keep the Inlet Shutoff Valve in the
closed position while allowing the changing of
the upper half of the valve (Outlet Adapter)
including the Pilot Valve.
Remove the quick disconnect fitting and dry the

interior of the air cavity and fitting with a blast of
clean, dry air. Perfection in this is not required,
but closely examine and mentally record the
condition of the air cavity after cleaning for
comparison as noted below.
Within the above sections of the hydrant valve

there are various seals that prevent leakage
between the elements. In a valve that is in good
mechanical condition, the Inlet Shutoff Valve and
Pilot Valve combine to keep the chamber
between the Inlet Shutoff Valve and the Outlet
Adapter at a lower than inlet pressure. This is
only possible, theoretically, if there is zero
leakage past the piston and Pilot Valve seals.
Any leakage, with the passage of time, will allow
this chamber to increase to inlet pressure. Fuel is
not compressible, hence a very small amount of
leakage will raise the pressure in this chamber to
inlet. This does not mean that a hydrant valve is
always "hot". If the leakage rate past the
appropriate seals is greater than the amount of
flow possible through the pressure equalization
valve (at the time the coupler is attached and
begins to be opened) then the valve is "hot". In
other words, the equalization valve's capacity is
insufficient to reduce the pressure in this
chamber during the coupler opening operation.
Refit the quick disconnect fitting. Establish full

hydrant system pressure to the hydrant's inlet.
Using a clean, dry source of air, which is set to
the same pressure used during normal operation
of the air pilot, apply and then remove the air
pressure, cyclically, thirty (30) times (one to two
seconds on, then one to two seconds off). When
completed, remove the air fitting and inspect the
air cavity again. Any accumulation of fuel, not
logically associated with residual moisture
available in the air cavity, indicates that the air
pilot is responsible for air system contamination.
Replace this air pilot with a new or rebuilt air
pilot. Overhaul of the air pilot while in the pit is
not recommended.
If no significant fuel is found in the air chamber
after the above investigation, it can be assumed
that the residual fuel previously seen in the air
chamber came from another source (coupler or
in line valve).

WHAT PROBLEMS ARE CAUSED BY HOT

HYDRANTS? - Two major problems, not readily
apparent, are caused or are potentially caused
by hot hydrants.
Hot hydrant valves make the opening of

the hydrant coupler more difficult. The hydrant
valve has a poppet area, against which pressure
reacts, of approximately 12.6 square inches. If
the pressure against which this poppet must be
opened is reduced appropriately by the pressure
equalization valve to about 20 psi, the opening
force that must be generated by the coupler
mechanism is only 252 pounds. If, on the other
hand, the valve is hot and the inlet pressure is
as much as 150 psi, the opening force must be
1,890 pounds. Under normal pressure
conditions, it is relatively easy to open a valve
against 20 psi with the application of
approximately 30 pounds force applied to the
coupler handle (mechanical advantage reduces
the force required). If the pressure is increased,
by a hot hydrant, to 150 psi, the force
necessarily applied to the coupler handle is
increased to 225 pounds. This is outside of the
realm of an average refueler so he will use his
foot and force the handle to the open position.
This tends to over stress the coupler mechanism
resulting in a premature failure condition, hence
expensive, unnecessary maintenance costs.
"Hot Hydrant" Check - A Carter hydrant valve

consists of four major components all contained
within a single valve element:
Outlet Adapter - A spring loaded poppet

valve that is manually opened and allowed to
close by the opening and closing of a mating
coupler. A pressure equalization valve is
contained within the poppet. This allows the
trapped pressure in the upper chamber of the
valve to be bled into the hydrant coupler when
extending the poppet to the open position.
Inlet Shutoff Valve (Isolation Valve in the

terms of the IP) - A spring loaded piston valve
whose chamber is connected to the inlet of the
hydrant valve via an orifice and to the outlet
through the servicing and pilot valves. Its function
is to control opening and closing times and to
present a means for shutting off flow at the end of
a refueling operation, either by means of a lanyard
or air operated pilot valve.
Pilot Valve or the Valve Connector

Assembly (on Option X) - Either the Valve
Stem Assembly on Option X or a lanyard or air
operated valve that controls the outlet bleed path
from the Inlet Shutoff Valve to the chamber
between the Inlet Shutoff Valve and the Outlet
Adapter.
A hot hydrant valve, caused by a failed Pilot

(including the Valve Stem Assembly (9-7) on
Option X) or Inlet Shutoff Valve can be a
potential major spill, with the possibility of a fire. A
recent incident, with a competitors hydrant valve,
12
SM60554
January 2011
in the first test (assuming that the leakage was

well below the 500 cc/min. allowable), it is a good
indication that the pilot valve seals or valve stem
are leaking and in need of overhaul. If the leakage
rate is significantly lower, the first assumption that
the majority of the leakage originally measured
was through the piston seals was faulty and it
could be an indication that the seals of the
servicing valve are faulty. If the leakage rate
remains approximately the same as in the first
test, the pilot valve and servicing valve seals
would appear to be performing well and that the
original assumption (leakage past the piston) was
correct.
resulted in a major spill. The coupler was knocked

off a functioning hydrant valve by a baggage cart.
The Outlet Adapter Poppet stuck open and the
Inlet Shutoff Valve failed to close because of a
non-functioning air operated pilot, even though the
air hose to the unit was also severed. The result
was a fairly major spill and luckily no fire. The
failure was caused by the fact that the Pilot
Valve's poppet, a synthetic ball, had deteriorated
resulting in the failure. Subsequent testing of other
valves at the location revealed nearly 50% were in
the same dangerously potential situation. Periodic
testing of the hydrant valves would have
prevented this situation from occurring. The fixing
of the hot hydrant valves would also make the
refueling operation easier and reduce, significantly,
the coupler maintenance costs.
Disconnect the test coupler and close the

pilot valve (leave the 64230/ 64231 Actuator
disconnected on Option X) before completing
the test.
TESTING PROCEDURES - It is recommended

that all new hydrant valves be tested after one
year of service and at lease twice each year
thereafter and any indicated hot hydrant valves
be removed for maintenance immediately. The
test procedure recommended is the same for a
lanyard or air operated unit.
Simple Test (will not test Servicing Valve

Seals) - This test can be conducted on air
operated units with the same equipment less the
pressure source but it is not as complete and will
not test the Servicing Valve. The Pilot Valve will
remain closed during all phases of this test.
Equipment Required - 61525E Coupler with

pressure sense port in the elbow and the outlet
plugged or a standard 61525 (any outlet thread)
with a small (3/8") port in the outlet plug. A 60 psi
air or nitrogen pressure source (for air operated
valves only); a short length of 3/8" plastic tubing or
hose attached to the pressure sense or outlet port,
a manual valve in the hose or tube; a 1000 cc
beaker; and a plastic 2 gallon bucket. (Note if a
metal bucket is used, check with your company
manual about electrical bonding of the bucket to
the coupler before proceeding.)
Close the Servicing Valve and conduct the

leakage test specified above.
Open the Servicing Valve and recheck the

leakage. If the leakage increases significantly, the
pilot valve seals or valve stem assembly on Option
X will be the contributor to the increased leakage.
If the total leakage is less than 500 cc/minute, the
valve can continue to be used. If greater, replace it
immediately.
7.2
Inlet Piston Valve Seals Test - Attach the

above test coupler to the test hydrant valve with
the coupler of the small shutoff valve open to the
bucket and open the hydrant valve by pulling the
T handle of Option D or by applying 60 psi air
pressure to the pilot port of Options E or J. Allow
the hydrant valve and coupler to be bled of air.
Close the servicing valve of the test hydrant. Allow
the leakage, if any, from the outlet to stabilize for
about 30 seconds, then measure the leakage for at
least 30 seconds. The amount of leakage caught
in the 30 seconds should not exceed 250 cc. If it
does, the hydrant valve should be tagged for
removal and overhaul.
DETAIL PARTS INSPECTION

It is recommended that the parts in the following
table be replaced at each overhaul. Detail
inspection of parts shall be conducted in
accordance with the information in the following
paragraphs.
SAFETY NOTE:
Any and all quick disconnect fittings used to
connect the air system to the hydrant valve must
be configured or altered to not tightly shut off the
air pilot's air cavity. Without this feature, full
hydrant system pressure could build in the air
pilot's air cavity as a result of the leaking air pilot.
The hydrant would then be in an open condition
or would be a "hot" unit causing problems in
connecting the coupler. This would defeat the
safe use of the hydrant as it was designed and
would increase maintenance costs for the
coupler.
Pilot Valve, Valve Stem Assembly on Option

X & Servicing Valve Seals Test - Close the
pilot valve (pull the lanyard on Option D, remove
the air pressure from Options E, F or J) or on
Option X do not connect the hydrant hose from
the service cart and open the servicing valve.
(The valve will remain in the closed position and
the leakage rate under this condition should
remain the same as in the test above, assuming
the leakage measured was the result of faulty
piston seals). Repeat the leakage test above. If
the leakage is significantly greater than that noted

utilized for sealing purposes can be

accomplished by using the process outlined in
the following paragraphs.
Inspect all metal parts for dings, gouges,

abrasions, etc. Use 320 grit paper to smooth and
remove sharp edges. Replace any part with
damage exceeding 15% of local wall thickness.
Use alodine 1200 to touch up bared aluminum.
7.2.2
If present, inspect Strainer (2-21) for damage

and presence of dirt. Clean thoroughly to
remove any potential blockage.
7.2.3
Inspect the exterior sealing and interior sealing

surfaces on the outlet of the Upper Half Assy (26), where it mates the hydrant coupler and
where the Seal (2-10) makes contact, for nicks,
gouges or other distortions that may be a cause
for leakage during operation. If the two-piece
upper housing is present and the sealing surface
is damaged, replace Ring (3-4). Check the red
coating, if present for chips and missing
portions. If the chips are apparent in the various
sealing areas, it is necessary to strip and recoat
the part. This can be accomplished by either of
two companies:

Leakage & Proof Pressure - Attach valve to a

static fuel pressure source of 300 psig minimum.
Open Pilot Valve (1-D, 1-E, 1-F, 1-J or 1-U) or
on Option X attach either the 64230 or 64231
Actuator Assembly and open the Valve
Connector Assembly (1-X), open Servicing
Valve (4-3) and fill valve manually opening the
Pressure Equalization Poppet (2-13) in the outlet
Poppet (2-11) to allow trapped air to escape.
Blow the external wetness off of the valve and
pressurize the unit to 25 psig and 300 psig for a
minimum of one minute at each pressure and
observe for external leakage. There should be
no leakage.
9.2.2
Seal Leakage - With the unit in the same test

setup, close pilot valve or remove the Actuator
Assembly (Option X) and block the outlet
Poppet open with a soft plastic rod (see
paragraph 6.1 for hint). Apply 25 and 300 psig
for one minute at each pressure and observe for
leakage as evidenced by fuel flow out of Poppet
(2-11). There shall be no leakage from unit.
9.2.3
Servicing Valve Leakage - With the same test

setup, close Servicing Valve (4-3) and open Pilot
Flow Tests - Install the valve in high flow test

stand. Connect the outlet of the unit to a Carter
61525 Coupler. Open Pilot Valve (1-D, 1-E, 1-F,
1-J or 1-U) or on Option X attach either the
64230 or 64231 Actuator Assembly and open
the Valve Connector Assembly (1-X). With 120
psig deadhead pressure establish a flow rate of
1100 USGPM.
9.2.4.1 Close the Pilot Valve (1-D, 1-E, 1-F, 1-J or 1-U)
or remove the Actuator Assembly (Option X)
and observe closing time and overshoot.
Overshoot is defined as the volume of fluid that
passes through the valve after the pilot valve
has been closed. Closing time shall be 2 to 5
seconds and overshoot shall be less than 55
gallons at 1,100 USGPM.
9.2.4.2 Opening Time - Using the same test setup, start
with a closed valve and 120 psig deadhead
pressure, open Pilot Valve (1-D, 1-E, 1-F, 1-J or
1-U) or on Option X attach either the 64230 or
64231 Actuator Assembly and open the Valve
Connector Assembly (1-X) and observe opening
time. Opening time is defined as the time
required for the valve to achieve at least 90% of
rated flow, 990 USGPM in this case. The
opening time shall be 5 to 10 seconds.

TROUBLE SHOOTING
10.1
External Leakage - Between Upper and Lower

Housing Assy (2-6 & 3-1). - Flange Screws (2-3
& 2-5) not tightened properly or O-Ring (2-22)
pinched or cut.
10.2
Leakage past Servicing Valve (4-3). - Damaged

Poppet (4-4).
10.3
Leakage past Equalization Valve Poppet (2-13). Damaged Seal (2-12) or Poppet (2-13).
10.4
Valve does not close when Pilot Valve (1-D, 1-E,

1-F, 1-J or 1-U) or the Actuator Assembly on
Option X is closed. - If unit closes when
Servicing Valve is shut, problem could be a
damaged or leaking Pilot Valve Poppet (5-22 or
5-3), Stem (9-11) or O-Ring (5-1, 6-11, 7-11, 811 9-8). If Pilot Valve 1-E, 1-F, 1-J or 1-U is
used, check to see if Piston (6-14) is free to
travel open and closed. If Lanyard Pilot 1-D is
used, check to see if Cable Assy (5-10) has
been pulled to allow the pilot to close. On Option
X be sure to remove air/fuel pressure from
Actuator Assembly.
10.5
10.6
11.0
January 2011
to 80 psig air pressure several times before

checking for leaking Bal Seal (6-15). Leaking Bal
Seal (6-15) should be evidenced by air flowing
out of the gap between the Cover (6-12, 6-2, 7-2
or 8-22) and the Housing (6-1). On Option X
check to see that the 64230/64231 is working
properly see SM64230/ SM64231.
Valve does not close when Pilot Valve (1-D, 1-E,

1-F, 1-J or 1-U) is closed, when air/fuel pressure
is removed from Actuator Assembly on Option
X or when Servicing Valve (4-3) is shut. - If flow
rate, when attempting to close the valve,
changes very little, the problem could be
damaged Piston Slipper Seal (4-25) and/or ORing (4-24) or jammed main Piston (4-18).
Check for movement (manually) of Piston (4-18).
If the flow rate changes to leakage when the
valve is signaled to close, the problem could be
the Piston Seal (4-21). Check also to be sure
that the piston on either the 64230 or 64231
Actuator Assembly on the hose is working
properly.
On units with an Air Operated Pilot Valve (1-E,
1-F, 1-J or 1-U) or Option X - Valve will not
open when air pressure is applied - Damaged
Bal Seal (6-15), Piston (6-14) is binding or
damaged bore of Housing (6-1). Actuate with up
10.7
On units with an Air Operated Defuel Pilot Valve

(1-J). - Valve will not open when air pressure is
applied - Defuel Screw (6-23) is screwed in too
far. Back out the Screw (6-23) until it is stopped
by Pin (6-24).
10.8

(1-J). - Valve will not open to allow defueling
operation - Defuel Screw (6-23) is not screwed in
far enough. Be sure the Screw (6-23) is
bottomed out on the Piston (6-14).
10.9

(1-J). - Valve will not open to allow defueling
operation - Incorrect Piston Seal Retainer (4-20)
is installed. The correct Seal Retainer (4-20) to
have defueling capability is part number 207727.
The height of the Seal Retainer (4-20) should be
approximately 0.540 (13.72 mm) to be correct.
Replace Seal Retainer (4-20) with correct part.
10.10
On units with a Lanyard Operated Pilot Valve (1D). - If the valve won't open, check to see that
the Latch Spool (5-4) remains in the locked up
position. Pull and hold up the Handle (5-6) for 30
seconds. If flow is established, the Latch Spool
(5-4) is not locking in the open position. Problem
could be wear either on the Latch Bracket (5-9)
or Latch Spool (5-4).
10.11
Fuel leakage into the air reference system (on

air operated pilot valve units only, option E, F, J
or U). - O-ring (6-9), (7-9) or (8-9) needs
replacing.
10.12
On Dual Pilot Units, Option F or U, if the valve

does not open when deadman is activated,
manual pilot may need resetting to prevent the
air pressure from bleeding out of the unit.

1.
Order one 47576 Valve Connector Assembly (for air/fuel operation) kit (shown to the right) for each hydrant
valve.
2.
Order special tool T221790 (only one per airport is needed).
3.
Remove and discard the existing pilot valve and cage from the hydrant valve.
4.
Using the special tool screw the cage into the hydrant valve body.
5.
Once the 48573 is seated and tightened install the 47574 Connector Assembly using the two screws provided.
6.
Retrofit the hydrant servicers by ordering one each 64230 or 64231 Actuator Assembly as appropriate to your
operation for each servicer. Replace the existing disconnect on the hose to the hydrant valve with the
64230/64231 as appropriate. It is recommended that at least one spare 64230 or 64231 Actuator Assembly be
ordered for each airport.

Notes:
January 2011
1.
All part numbers beginning with "GF" are interchangeable with those beginning with either "AN" or "MS".
If the "GF" is followed by three numbers it is interchangeable with and "AN" part, otherwise it is
interchangeable with an "MS" part of the same number.
2.
The recommended spare parts shown above are the number required to support 10 Units for one year or
each overhaul whichever is sooner. These quantities do not include replacement spares for intermediate
replacement of parts required by abuse or misuse of the equipment. The recommended quantities are
based on the ratio of spare parts sold for each unit during a one year period of time. The actual quantity
required will vary from location to location.
3.
These items are not sold as separate parts, only the next assembly is available.
4.
It is recommended that at least one each be on hand for each 50 or less hydrant valves in the system.
5.
Air/Lanyard Pilots can be purchased without the Cage (7-2) or (8-2) and O-ring (7-11) or (8-11) if it is
desired to replace the unit as a complete pilot valve. The Cage (7-2) or (8-2) and O-ring (7-11) or (8-11)
can then be left installed inside the hydrant valve and need not be replaced. The part numbers for this
replacement pilot valve would be 47091-3 for Option F pilot valve without the M Option or 47051-4 with
the M Option. For Option U pilot valve without M Option it would be 47362-3 or with Option M it would be
47362-4.
6.
The obsolete items 22-24 in Table 6 are no longer available as spare parts. If any one of the parts is
ordered it will automatically be replaced with 47370 Screw Assembly.
7.
The obsolete item 2-11 is no longer available as a spare part. If it is ordered it will be replaced by
KD60554-10 to upgrade the poppet to the latest steel version.
