Disassembly

1. Install 307-577 on the transfer shaft bearing cup.





2. Install 204-069 (T81P-1104-C) and thread it into 307-577.





3. Using a wrench, turn the nut on 204-069 (T81P-1104-C) to remove the transfer shaft bearing cup from the torque converter housing.





4. Remove the preload shim.





5. Punch a hole in the fluid dam.





6. If the transfer shaft bearing cup was removed, use a dent puller to remove the fluid dam from the torque converter housing.





7. Install 307-586 on the bearing cup.

1. Position 307-586 in the torque converter housing with the tabs on 307-586 aligned with the slots in the torque converter housing.

2. Expand 307-586 by hand.

3. While holding 307-586 in the expanded position with the tabs in the slots of the torque converter housing, tighten the nut.






8. Using a press, press the differential bearing cup out of the torque converter housing.





9. Remove the differential bearing preload shim.





Assembly

1. Install the differential and transfer shaft bearing cups on the bearings.





2. Install 307-591 on the differential and transfer shaft bearing cups.





3. Install 307-591 /3 (studs) in the transaxle case to align the torque converter housing.





4. NOTE: Make sure that the silicone has been cleaned off the machined surface of the transaxle case and the torque converter housing before installing 307-591 /3 (4 spacers) or the preload measurement may be inaccurate.
Install 307-591 /3 (4 spacers) on the studs to space the torque converter housing from the transaxle case.





5. Place the torque converter housing on 307-591 /3 (4 spacers).





6. Install 307-591 /3 (remaining 4 spacers, bolts and washers).
- Tighten to 24 Nm (18 lb-ft).





7. Install 307-591 /3 (4 nuts and washers) on the studs.






8. Rotate the transfer shaft and the differential several times to seat the bearings.





9. Using a feeler gauge, measure and record the smallest and largest preload gap on 307-591 /1 placed on the differential assembly. Add the 2 measurements and divide by 2. This is the thickness of the differential bearing preload shim. For additional information, REFER to General Specifications for the differential bearing preload shim part number.





10. Using a feeler gauge, measure and record the smallest and largest preload gap on 307-591 /2 placed on the transfer shaft assembly. Add the 2 measurements and divide by 2. This is the thickness of the transfer shaft bearing preload shim. For additional information, REFER to General Specifications for the transfer gear bearing preload shim part number.





11. Remove the torque converter housing and 307-591 /3 (4 nuts, bolts and spacers and 8 washers) from the transaxle case.





12. Remove 307-591 /3 (4 spacers) from the transaxle case.





13. Remove 307-591 /3 (4 studs) from the transaxle case.





14. Remove 307-591 /1 and 307-591 /2 from the differential and transfer shaft assemblies.





15. Remove the differential and transfer shaft bearing cups.





16. Assemble 205-153 (T80T-4000-W) and 307-583 and install a new transfer shaft fluid dam on 307-583.





17. NOTICE: Support the torque converter housing using blocks of wood, or damage to the torque converter housing may occur.

Using 205-153 (T80T-4000-W) and 307-583 , install the fluid dam in the torque converter housing.





18. Inspect the transfer shaft fluid dam to be sure it is seated evenly into the torque converter housing.





19. Install the transfer shaft preload shim in the torque converter housing.





20. Using 307-576 , press the transfer shaft bearing cup in the torque converter housing.





21. Install the differential bearing preload shim in the torque converter housing.





22. Install a new differential bearing race on 307-576.





23. Using 307-576 , 307-541 and 204-029 (T77F-1176-A) , press the differential bearing cup in the torque converter housing.
