Differential: Adjustments
BEARING PRELOADNOTE: Whenever the transaxle is disassembled, the bearing preload must be adjusted. The differential bearing preload can be adjusted by selecting shims to insert between the ring gear end bearing cup and the transaxle case. To determine the correct thickness shim, use Shim Selection Sets T88C-77000-JF and T88C-77000-C, along with the following procedure:
1. Install the differential bearing cup into the flywheel housing using Driver Handle T80T-4000-W and Differential Bearing Cup Replacer T88C-77000-FH.
2. Inspect the bearing cups after installation to make sure they are fully seated.
3. Install the differential into the flywheel housing.
4. Place the ring gear end bearing cup on the differential bearing.
5. Position Shim Selection Gauge T88C-77000-CH3 (part of T88C-77000-C) on top of the differential.
NOTE: The gauge halves must be turned to eliminate any gap between them.
6. Place the six collars (part of T88C-77000-JF) on the flywheel housing.
NOTE: The six collars (part of T88C-77000-JF) should be placed at the same locations on the flywheel housing as explained in the input shah shim selection procedure, described.
7. Place the transaxle case on the collars and then install the washers and bolts (part of T88C-77000-JF). Tighten the collar bolts to 38-51 Nm (28-38 ft lbs.).
8. Adjust the gauge tool (using the pins provided in T88C-77000-JF) until the free play is removed and the bearing cup is seated. Thread the gauge tool halves back together.
9. Insert Differential Rotator T88C-77000-L through the transaxle case and engage the differential pinion shaft.
10. Attach a torque wrench to the differential rotator.
11. Turn the gauge using the adjusting rods (part of T88C-77000-JF) until a reading of 0.5 Nm (4.3 inch lbs.) is obtained on the torque wrench.
12. Use a feeler gauge to measure the gap in the shim selection gauge. Measure the gap in four locations at 90° intervals. Use the largest measurement.
13. Add 0.15 mm (0.0059 inch) to the measured clearance.
14. Use the following chart to select the differential bearing shims that are closest to (or slightly larger than) the value obtained in Step 13.
NOTE: Do not use more than two differential bearing shims.
15. Remove the bolts and washers securing the transaxle case to the flywheel housing. Remove the transaxle case, collars, gauge, ring gear end bearing cup and differential. Do not remove the speedometer drive gear end bearing cup in the flywheel housing.
