HYDRAULIC SYSTEM RT9130E-2 SERVICE MANUAL
converter pump disconnect shaft with attaching
hardware.
6. Adjust the push-pull cable as needed so the torque
converter pump disconnect shaft sticks 1.50 in (38.1
mm) farther out of the torque converter in the
disengaged position than it does in the engaged
position.
7. Connect the distribution and supply lines to the pump as
tagged during removal. On lines that use them, discard
any old O-ring and install a new O-ring in its place.
No. 4 Pump Removal
1. Remove hardware as needed to gain access to the
pump. The pump is bolted to the engine.
2. Tag and disconnect the supply line from the pump. Cap
or plug the line and port.
3. Tag and disconnect the pump distribution lines from the
pump. Cap or plug the lines and ports.
4. Remove the two bolts and washers attaching the pump
to the drive pad of the engine. Remove the pump.
5. Remove the two gaskets and spacer from the pump (or
the.engine drive pad). Discard them.
6. Cover the drive pad’s opening to prevent dirt from
entering.
7. Remove the nut, key, and gear from the pump.
No. 4 Pump Installation
1. Ensure the mating surfaces of the pump shaft and gear
are clean and dry. Install gear on pump’s tapered shaft.
Secure gear with key and nut. Torque nut to 120 ft-lb
(163 Nm). Remove the nut and apply Loctite 243 to the
threads. Install the nut and retorque to 120 ft-lb(163
Nm).
2. Clean the pump and the engine drive pad with Loctite
cleaning solvent 7070 or similar non chlorinated solvent.
Likewise clean both surfaces of the new rubber/steel
gasket, the spacer, and the new vellomoid gasket.
3. Apply a light coating of Loctite primer N7649 to Pump
No. 4’s mounting surface, but do not apply any to the
engine’s drive pad. Also apply a light coating of Loctite
primer N7649 to both surfaces of the vellomoid gasket,
and apply a light coating of Loctite primer N7649 to the
surface of the spacer that will be next to the vellomoid
gasket, but not to the surface of the spacer that will be
next to the rubber/steel gasket. Do not coat either side of
the rubber/steel gasket or the facing sides of the parts
that will touch it. Allow primer to dry for one to two
minutes. Primer must be dry. Mating of parts should
occur within five minutes.
4. Apply gasket material Loctite Master Gasket 518 to
Pump No. 4’s mounting surface, but do not apply any to
the engine’s drive pad. Also apply a light coating of
Loctite Master Gasket 518 to both surfaces of the
vellomoid gasket, and apply a light coating of Loctite
Master Gasket 518 to the surface of the spacer that will
be next to the vellomoid gasket, but not to the surface of
the spacer that will be next to the rubber/steel gasket.
Do not coat either side of the rubber/steel gasket or the
facing sides of the parts that will touch it. (This material
partially cures in 4 hours and fully cures in 48 hours.)
5. Around the pilot of the pump, install the vellomoid
gasket, then install the spacer (coated surface away
from rubber/steel gasket), then install the rubber/steel
gasket. Then secure the pump and gaskets and spacer
on the drive pad with bolts and washers. Make sure the
teeth of the gear on the pump mesh properly with the
mating gear inside the engine. Refer to Fasteners and
Torque Values, page 1-18 for the torque value for the
pump mounting bolts.
6. Connect the distribution and supply lines to the pump as
tagged during removal. On lines that use them, discard
any old O-ring and install a new O-ring in its place.
Testing After Repair or Replacement
1. Ensure the reservoir is filled with the proper hydraulic
fluid to the high level mark on the reservoir sight gauge.
2. Ensure no air is entering the pump inlet, and that the
pump suction or inlet fluid is not bleeding back to the
reservoir when the engine is stopped, by making sure all
suction or inlet lines are air tight.
3. Remove all pump outlet hoses. Fill pump outlet port of
each pump section with as much hydraulic oil as it can
take. Connect all pump outlet hoses again.
4. Start the engine and idle it for two or three minutes
without running any hydraulic functions. Check for leaks;
as needed, stop the engine and make repairs.
CAUTION
Absolute cleanliness is essential when working on the
hydraulic pumps. Always work in a clean area. The
presence of dirt and foreign materials in the system can
result in serious damage or inadequate operation.
CAUTION
When removing the pump, keep the pump as level as
possible to avoid damaging the input spline.
CAUTION
Do not feed hot hydraulic oil into a cold pump. This may
cause the pump to seize.
