Differential Bearing (Side Bearing) Preload

Differential bearing (side bearing) preload

Notice: The next eighteen steps measure differential side bearing preload and select proper adjustment shim(s).





1. Remove side bearing outer race and adjustment shims from transaxle case.
2. Set transaxle case on a stand and install SST (OK130 191 A07/K94A-4200-T).





3. Tighten SST (OK130 191 A06/K94A-4200-T) to specified torque.
Tightening torque: 27 - 38 ft. lbs. (36 - 51 Nm, 3.7 - 5.3 kg.m)
4. Set differential assembly into converter housing.

Notice: Eliminate gap (arrow) by turning either A or B of selector. Do not overtighten.





5. Install side bearing outer race removed from transaxle case into SST (OK201 175 A01 / K94A-4200-T). Set SST and outer race onto differential assembly.





6. Set SST (OK130175A02/K94A-4200-T) on converter housing in positions shown.
7. To seat bearing, turn SST (OK201 175 A01 / K94A-420-T) to increase clearance indicated by arrow with SST (OK130 175 A03/K94A-4200-T) until it no longer turns.





8. Turn selector in opposite direction until gap is reduced.
9. Insert SST through transaxle case and attach it to pinion shaft.
10. Install torque meter.

Notice: Read preload when differential is rotating.

11. Adjust clearance between A and B to obtain specified preload reading.
Preload: 4.3 inch lbs. (0.5 Nm, 0.05 kg)





12. Measure clearance between A and B.





13. Add 0.0118 inch (0.3 mm) to measured clearance and select shim(s) closest in value to measurement.

Notice:
a) Measure clearance around entire circumference and select shims based on maximum clearance.
b) The maximum allowable number of shims is 3.





14. Remove transaxle case and SST (K94A-420-T).





15. Install required shim(s) and tap bearing race into transaxle case.
16. Install transaxle case.
Tightening torque: 28 - 38 ft. lbs. (38 - 51 Nm, 3.8 - 5.1 kg.m)





17. Using SST (OK130 191 A05/K94A-420-T) and a torque meter, verify that preload is within specification. If not within specification, return to Step 1.
Preload: 27.6 - 33.6 inch lbs. (3.0 - 3.9 Nm, 30 - 40 kg.cm)
18. Remove transaxle case.
