Differential Bearing Preload

DIFFERENTIAL BEARING PRELOAD





1. Remove the bearing race and adjustment shim from the converter housing using the SST.





2. Install the bearing race into the transaxle case.





3. Set the differential on the transaxle case.





4. Turn the selector to eliminate the gap between its two halves.
5. Install the bearing race removed in Step 1 into the SST.





6. Set the differential on the SST (selector).





7. Set the six SSTs (collars) on the transaxle case in the position shown.





8. Set the converter housing on the transaxle case and tighten the SSTs (bolts) to the specified torque.
Tightening torque 19 - 25 Nm (1.9 - 2.6 kgf-m, 14 - 18 ft. lbs.)
9. Turn the SST (selector) to increase the clearance (arrow) using the SSTs (bars), until it no longer turns. This is to seat the bearing race.





10. Turn the selector in the opposite direction until the preload is eliminated (gap is reduced).
11. Insert the SST through the converter housing and attach it to the pinion shaft.
12. Install the SST and a pull scale or torque wrench.

Note:
^ Read the preload when the differential starts to turn.
^ Measure several times and calculate the average value.








13. Adjust the clearance of the SST (selector) to obtain the specified preload/pull scale reading.
Preload: 1.4 - 2.3 Nm (14 - 24 kgf-cm, 12 - 20 inch lbs.)
Reading on pull scale: 14 - 23 N (1.4 - 2.4 kgf, 3.1 - 5.3 lbs)
14. Measure the clearance as shown.





15. Take the maximum reading and determine the shim to be used.






Adjustment shim sizes





16. Remove the converter housing and SST (selector).
17. Install the required adjustment shim and tap the bearing race into the converter housing.
18. Install the converter housing.
Tightening torque 19 - 25 Nm (1.9 - 2.6 kgf-m, 14 - 18 ft. lbs.)
19. Install the SST to the pinion shaft through the converter housing.

Note: Measure several times and calculate the average value.

20. Verify that the preload is within the specification. If not, return to Step 1.
Preload 1.4 - 2.3 Nm (14 - 24 kgf-cm, 12 - 20 inch lbs.)
Reading on pull scale 14 - 23 N (1.4 - 2.4 kgf, 3.1 - 5.3 lbs)
21. Remove the converter housing.
