Bearing Preload

Bearing preload
1. Remove bearing outer race from bearing cover.
2. Install bearing cover with SST (OK201 190 017) or equivalent.





3. Align bearing cover with guide bolts as shown, and press it in. Torque bearing cover bolts.
Tightening torque: 96 - 120 inch lbs. (10.8 - 13.7 Nm, 110 - 140 kg.cm)





4. Remove bearing outer race and adjustment shims from bearing housing using a pin punch and hammer.





5. Install bearing outer race to bearing housing.

Notice: Do not install adjustment shims.

Notice: Eliminate gap (arrow) by turning A or B of selector.

6. Set SST (OK201 175 A01/K94A-4200-T1) onto converter housing.





7. Install outer race removed in step 1 to SST (OK201 175 A01/K94A-4200-T1).
8. Set output gear assembly onto SST (OK130 191 A03/K94A-4200-T1).





9. Set four SST (OK130191A03) on converter housing in positions shown.





10. Set bearing housing on output gear assembly and install four SST (OK130 175 A04); then tighten them to specified torque.
Tightening torque: 14 - 18 ft. lbs. (19 - 25 Nm. 1.9 - 2.6 kg.m)
11. To seat bearing, turn SST (OK201 175 A011212249) to increase clearance indicated by arrow with SST (OK130 175 A03/212249) until SST (OK130175A03/212249) no longer turns.





12. Turn selector in opposite direction until gap is reduced.
13. Mount SST (OK130 322 020/K94A-4200-T1) and torque meter on output gear.





14. Adjust clearance of SST (OK130 175 A03) to obtain specified preload.
Preload: 0.27 - 7.8 inch lbs. (0.03 - 0.8 Nm, 0.3 - 9.0 kg.cm)





Notice: Read preload when output gear is rotating.

Notice:
a) Measure clearance around entire circumference and select shims equivalent to maximum clearance.
b) The maximum allowable number of shims is 7.





15. Measure clearance. Select adjustment shim(s) equivalent to measured clearance.





16. Remove bearing housing and SST (OK201 175 AAO/212249).





17. Remove bearing outer race from bearing housing.
18. Install required shim(s)
19. Press bearing race into bearing housing with SST (or equivalent).





20. Press bearing outer race into bearing cover.





21. Install output gear assembly and bearing housing.
Tightening torque: 14 - 18 ft. lbs. (19 - 25 Nm, 1.9 - 2.6 kg.m)

Notice: Do not install idler gear at this time.

22. Using SST (OK130 191 A04/K94A4200-T2) and a torque meter, verify that preload reading is within specification.
Preload: 0.27 - 7.8 inch lbs. (0.03 - 0.8 Nm, 0.3 - 9.0 kg.cm)





23. Remove bearing housing and output gear assembly.
