RT9130E-2 SERVICE MANUAL HYDRAULIC SYSTEM
1. Remove hardware as needed to gain access to the
pump. The pump is bolted to the drive-through charge
pump on the engine’s torque converter.
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-through charge pump on the torque
converter. Remove Pump No. 2.
5. Clean the gasket material from the drive pad of the
drive-through charge pump and from the pump.
6. Cover the drive pad’s opening to prevent dirt from
entering.
Pump No. 2 Installation
1. Clean the pump and the drive pad of the drive-through
charge pump with Loctite cleaning solvent 7070 or
similar non chlorinated solvent.
2. Apply a light coating of Loctite primer N7649 to pump
and drive-through charge pump drive pad. Allow primer
to dry for one to two minutes. Primer must be dry. Mating
of parts should occur within five minutes.
3. Apply gasket material Loctite Master Gasket 518 to
pump and drive pad mounting surfaces. (This material
partially cures in 4 hours and fully cures in 48 hours.)
4. Apply antiseize compound to the splined shaft of Pump
No. 2 and to the splined socket of the coupler on the
shaft inside the drive-through charge pump.
5. Install Pump No. 2 and gasket on drive-through charge
pump drive pad with bolts and washers. Make sure the
splined shaft of Pump No. 2 meshes properly with the
splined socket of the coupler on the shaft inside the
drive-through charge pump. 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.
No. 3 Pump Removal
1. Remove hardware as needed to gain access to the
pump. The pump is bolted to the engine’s torque
converter.
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 attaching hardware to free pump disconnect
linkage from torque converter pump disconnect shaft.
5. Remove the four bolts and washers attaching the pump
to the drive pad on the torque converter. Remove the
pump and the attached cable mounting weldment and
push-pull cable. Remove cable mounting weldment and
push-pull cable from the pump.
6. Clean the gasket material from the drive pad of the
torque converter and from the pump.
7. Cover the drive pad’s opening to prevent dirt from
entering.
No. 3 Pump Installation
1. Clean the pump and the torque converter drive pad with
Loctite cleaning solvent 7070 or similar non chlorinated
solvent.
2. Apply a light coating of Loctite primer N7649 to pump
and drive pad. Allow primer to dry for one to two
minutes. Primer must be dry. Mating of parts should
occur within five minutes.
3. Apply gasket material Loctite Master Gasket 518 to
pump and drive pad mounting surfaces. (This material
partially cures in 4 hours and fully cures in 48 hours.)
4. Install pump and gasket on drive pad with bolts and
washers. Make sure the splines mesh properly. Refer to
Fasteners and Torque Values, page 1-18 for the torque
value for the pump mounting bolts.
5. Install cable mounting weldment and push-pull cable on
the pump. Secure pump disconnect linkage to torque
CAUTION
When removing the pump, keep the pump as level as
possible to avoid damaging the input spline.
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.
