Transmission Fluid Pump Assembly Installation

Transmission Fluid Pump Assembly Installation

Special Tools
* J-36850 - Transaxle Lubricant
* J-45053 - Universal Clamp Press




1. Apply J-36850 - lubricant to the coast clutch hub thrust washer (226).
2. Install the coast clutch hub thrust washer (226) with the flat surface facing up, and with the tangs engaged into the second coast clutch spring (224).




3. While holding the second coast clutch hub and sprag assembly (11) together, install into the fluid pump assembly.




4. Place a straight edge on top of the second clutch sprag outer race thrust washer.
5. Measure the distance (b) from the bottom of the straight edge and the fluid pump assembly. Installed height should be 51.09-51.71 mm (2.011-2.036 in).
6. If the installed height is greater than specifications, the second coast clutch hub did not clear all the second clutch fiber plates. Index again the clutch hub and plates until within specifications.




7. Rotate the transmission assembly as shown.
8. Install the J-45053 - press on the fluid pump assembly.

* Do not allow the second clutch sprag assembly to separate from the clutch plates.
* Back out the forcing screw of the J-45053 - press to ensure, ample clearance of the input shaft.

9. Install the fluid pump assembly.

* Do not allow the input shaft splines to touch the bushings in the fluid pump assembly.
* Align the holes of the fluid pump assembly to the transmission case.
* Do not allow the second clutch sprag assembly to separate from the clutch plates.

10. Lightly press the fluid pump body into the transmission case assembly in order to seat the fluid pump assembly in place.





Caution: Do not use bolts longer than 28 mm. Using bolts longer than 28 mm will cause internal damage to the transmission.

11. Install the 8 - M8 x 1.25 x 28 mm fluid pump to case bolts (5) and hand tighten.




12. Rotate the transmission assembly so that the fluid pump assembly is facing up.

Caution: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

13. Tighten the fluid pump to case bolts in the correct sequence. Tighten the fluid pump to case bolts to 25 Nm (18 lb ft).
