Differential: Adjustments

BEARING PRELOAD
1. Remove the bearing race and adjustment shims from the transaxle case.
2. Set the differential into the converter housing.
3. Turn the selector to eliminate the gap between its two halves.





4. Install the bearing race removed in step 1 into the Special Service Tool (SST). Set the SST and bearing race on to the differential.





5. Set the six SST (collars) on the converter housing in the positions shown.
6. Set the transaxle case on the converter housing.





7. Tighten the SST (bolts) to 37 - 51 Nm (27 - 38 ft. lbs.).

NOTE: Bend the bar as shown to turn the SST.

8. Turn the SST (selector) to increase the clearance (arrow) by using the SST (bars), until it no longer turns. This is to seat the bearing race.





9. Turn the selector in the opposite direction until the preload is eliminated (gap is reduced).
10. Insert the SST through the transaxle case and attach it to the pinion shaft.
11. 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.





12. Adjust the clearance of the SST (selector) to obtain the specified preload/pull scale reading. Preload should be 0.5 Nm (4.3 inch lbs.) and the reading on pull scale should be 5 N (1.1 lbs.).

NOTE:
^ Measure the clearance around the entire circumference, and select shims based on the maximum clearance.

^ The maximum allowable number of adjustment shims is three.

13. Measure the clearance as shown.





14. Add 0.3 mm (0.0118 inch) to the measured clearance, and select the shim(s) closest in value to that measurement.
15. Remove the transaxle case and SST (selector).





16. Install the required adjustment shim(s) and tap the bearing race into the transaxle case.
17. Install the transaxle case. Tighten to 38 - 51 Nm (28 - 38 ft. lbs.).
18. Install the SST to the pinion shaft through the transaxle case.

NOTE: Measure several times and calculate the average value.





19. Verify that the preload is within the specification. If not, return to step 1. Preload should be within 3.0 - 3.9 Nm (27 - 34 inch lbs.) and the reading on pull scale should be within 30 - 39 N (6.6 - 8.8 lbs.).
20. Remove the transaxle case.
