Carrier Bearings: Adjustments

1. Place the differential into the converter housing.





2. Place Shim Selection Gauge (part of T88C-77000-JF), Shim Gauge Adapter Ring T9OP-7025-RH, and the rear bearing cup onto the differential.





3. Place the six collars (part of T88C-77000-JF) on the converter housing at the positions shown (A).





4. Set the transaxle case on the converter housing, then install the six collar bolts and washers (part of T88C-77000-JF).





5. Turn the Shim Selection Gauge to increase the clearance by using the rods (part of T88C-77000-JF) until the shim selection gauge no longer turns. This is to seat the bearing race. Turn the shim selection gauge in the opposite direction until the preload is eliminated (gap is reduced).





6. Insert the Torque Adapter T90P-7025-BH and attach a torque wrench to the adapter. Measure the drag on the differential bearing.

NOTE:
- Read the preload when the differential starts to turn.
- Take several measurements and calculate the average value.

7. Adjust the clearance of the shim selection gauge, using the rods, to obtain the specified preload.
- Preload should be 0.5 Nm (4.3 inch lbs.).





8. Use a feeler gauge to measure the gap between the two halves of the shim Selection Gauge. Add 0.3 mm (0.0118 inch) to the largest measurement. Select the shim(s) closest in value to the measurement from the following chart:

NOTE:
- Measure the clearance around the entire circumference. Select the shim(s) based on the largest clearance.
- Use no more than three shims.

9. Remove the bolts; washers, transaxle case, collars, shim selection gauge, and the bearing cup.





10. Use (A) Driver Handle T80T-4000-W and (B) Bearing Cup Replacer T77F-1217-B to install the required selective shim(s) and tap the bearing cup into the transaxle case.





11. Install the transaxle case.





12. Install Torque Adapter T9OP-7025-BH and a torque wrench to the pinion shaft through the transaxle case. Measure the bearing preload.
- Bearing preload should be 3.0-3.9 Nm (27-34 inch lbs.).

NOTE: Take several measurements and calculate the average value.

13. Repeat the gauging process if the preload is not within specification.
14. Remove the transaxle case.
