Bearing Preload
- Remove bearing outer race from bearing cover.
- Install bearing cover with SST (0K201 190 017) or equivalent.
- Align bearing cover with guide bolts as shown, and press it in. Torque bearing cover bolts.
Tightening torque: 96-120 lb.in (10.8-13.7 N.m, 110-140 kg.cm)
- Remove bearing outer race and adjustment shims from bearing housing using a pin punch and hammer.
- Install bearing outer race to bearing housing.NOTE: Do not install adjustment shims.NOTE: Eliminate gap (arrow) by turning A or B of selector.
- Set SST (0K201 175 A01/K94A-4200-T1) onto converter housing.
- Install outer race removed in step 1 to SST (0K201 175 A01/K94A-4200-T1).
- Set output gear assembly onto SST (0K130 191 A03/K94A-4200-T1)..
- Set four SST (0K130 191 A03) on converter housing in positions shown.
- Set bearing housing on output gear assembly and install four SST (0K130 175 A04);
then tighten them to specified torque.
- Tightening torque: 14-18 lb.ft (19-25 N.m, 1.9-2.6 kg.m)
- To seat bearing, turn SST (0K201 175 A01/212249) to increase clearance indicated by arrow with SST (0K130 175 A03/212249) until SST (0K130 175 A03/212249) no longer turns.
- Turn selector in opposite direction until gap is reduced.
- Mount SST (0K130 322 020/K94A-4200-T1) and torque meter on output gear.
- Adjust clearance of SST (0K130 175 A03)
to obtain specified preload.
- Preload: 0.27-7.8 lb.in (0.03-0.8 N.m, 0.3-9.0 kg.cm)
NOTE: Read preload when output gear is rotating.NOTE:- Measure clearance around entire circumference and select shims equivalent to maximum clearance.
- The maximum allowable number of shims is 7.
- Measure clearance. Select adjustment shim (s) equivalent to measured clearance.
- Remove bearing housing SST (0K201 175 AAO/212249).
- Remove bearing outer race from bearing housing, refer to Bearing and race locations.
- Install required shim (s).
- Press bearing race into bearing housing with SST (or equivalent).
- Press bearing outer race into bearing cover.
- Install output gear assembly and bearing housing.
Tightening torque: 14-18 lb.ft (19-25 N.m, 1.9-2.6 kg.m)
NOTE: Do not install idler gear at this time. - Using SST (0K130 191 A04/K94A4200-T2)
and a torque meter, verify that preload reading is within specification.
- Preload: 0.27-7.8 lb.in (0.03-0.8 N.m, 0.3-9.0 kg.cm)
- Remove bearing housing and output gear assembly.
