Thrust Bearing/Washer Locations
1. Use Driver Handle T80T-4000-W and Bearing Cup Replacer T77F-1217-B to install the bearing cup into the converter housing.
2. Place the differential (4026) into the converter housing.
3. Place six Collars (part of T88C-77000-JF) on the converter housing at the positions shown.
4. Place the rear bearing cup over the differential bearing (4221).
5. Place Shim Selection Gauge (part of T88C-77000-JF) and Shim Gauge Adapter Ring T90P-7025-AH on the output gear. Turn the two halves of the gauge to eliminate any gap between them.
6. Place the transaxle case on the collars, then install six collar Bolts and Washers (part of T88C-77000-JF). Tighten the collar bolts to 19-26 Nm (14-19 lb-ft).
7. Use Rods (part of T88C-77000-JF) to unthread the gauge halves until the free play is removed and the bearing cup is seated. Then thread the gauge halves back together.
8. NOTE: Read the preload when the differential starts to turn.
Engage Torque Adapter T90P-7025-BH and attach a torque wrench to the adapter. Measure the drag on the differential bearing.
9. Turn the gauge using the rods until a reading of 0.5 Nm (4.3 lb-in) is obtained on the torque wrench.
10. Use a feeler gauge to measure the gap between the two halves of the shim selection gauge. Measure the gap at four spots at 90 degree intervals. Use the largest measurement.
11. NOTE: Use no more than three shims.
Add 0.3mm (0.0118 inch) to the largest measurement. Select the shim(s) closest (or slightly larger) to this final value from the following chart.
12. Remove the bolts, washers, transaxle case, gauge, and bearing cup.
13. Use Driver Handle T80T-4000-W and Bearing Cup Replacer T77F-1217-B to install the selected shim(s) and bearing cup into the transaxle case.
14. Install the transaxle case. Tighten the transaxle case-to-converter housing bolts to 37-52 Nm (27-38 lb-ft).
15. Measure the bearing preload. The preload should be 2.9-3.9 Nm (26-35 lb-in). Repeat the gauging process if the preload measurement is not within specification.
16. When the proper preload specification has been obtained, remove the transaxle case.
