Pinion Gear: Adjustments

NOTE: Use the Special Service Tools (SSTs) illustrated to measure and adjust the output gear bearing preload.

BEARING PRELOAD
1. Align the bearing cover with guide bolts as shown.





2. Press in the bearing cover by using the SST.
3. Remove the guide bolts and install the bearing cover installation bolts. Tighten to 11 - 13 Nm (96 - 121 inch lbs.).
4. Mount the converter housing onto the SST (transaxle hanger).
5. Remove the bearing race and adjustment shims from the bearing housing using a pin punch and a hammer.





6. Set the output gear into the converter housing.
7. Install the bearing race removed in step (5) to the selector, and install the selector and bearing race to the output gear.





8. Turn the selector to eliminate the gap indicated by the arrow.





9. Set the four SSTs on the converter housing in the positions shown.





10. Set the bearing housing on the SSTs (selector) and install the four SSTs (bolts). Tighten the bolts to 19 - 25 Nm (14 - 18 ft. lbs.).





11. Turn the SST (selector) to increase the clearance (arrow) with the SST (bars) until it no longer turns.
12. Turn the selector in the opposite direction until the preload is eliminated (gap is reduced).





13. Mount the SST and a pull scale or a torque wrench on the output gear.
14. Adjust the clearance of the SST (selector) to obtain the specified preload/pull scale reading. Preload should be 1.1 - 1.9 Nm (10 - 17 inch lbs.) and the reading on pull scale is 11 - 19 N (2.5 - 4.4 lbs.).





15. Measure the bearing preload at the point that the output gear starts to turn.





16. Measure the gap around the circumference of the SST (selector) by using a feeler gauge.








17. Take the maximum reading and determine the shim to be used. Use no more than one shim.





18. Remove the bearing housing and the SST.
19. Install the required shim and press the bearing race into the bearing housing by using the SST.





20. Install the bearing housing and tighten to 19 - 25 Nm (14 - 18 ft. lbs.).
21. Check that the preload/pull scale reading is within the specification. If not, return to step (5). Preload should be 1.1 - 1.9 Nm (10 - 17 inch lbs.) and the reading on pull scale is 11 - 19 N (2.5 - 4.4 lbs.).
22. Remove the bearing housing and output gear assembly.
