Install bearing cups (20) and (21) in pinion housing (13) . Bearing cups (20) and (21) must be against the shoulders in pinion housing (13) .
Install bearing cone (14) next to the pinion teeth on bevel pinion (17) . Bearing cone (14) must be against the shoulder on bevel pinion (17) .
Lubricate the bearing and install bevel pinion (17) in pinion housing (13) . Lubricate bearing cone (12) and install bearing cone (12) .
Position the assembly in a soft jawed vise. Tighten the vise against the teeth on bevel pinion (17) . Install washer (19) and nut (11) . While you are turning pinion housing (13) , tighten nut (11) . Tighten nut (11) until the specified torque that is needed to turn bevel pinion (17) is reached.New bearings ... 0.9 0.2 N m (8.0 2.0 lb in)Used bearings ... 0.45 0.10 N m (4.00 1.00 lb in)Check bevel pinion (17) in order to ensure that there is zero end play.
If the bearing preload exceeds the specified torque, loosen nut (11) by 1/8 of a turn. Reseat bearing cone (12) . Repeat Step 4.
When the torque that is needed to turn bevel pinion (17) is correct, lock the nut (11) . Lock the nut (11) by bending one of the tabs on lock (18) into the closest slot in nut (11) . If necessary, tighten nut (11) slightly in order to align a slot in the nut with a tab on lock (18) .Note: The nut may be reused if the nut is not damaged during disassembly.Differential Backlash and Bearing Adjustment
Note: The following procedure controls backlash and bearing preload. This procedure gives the same results for used bearings and for new bearings.
Fasten pinion housing (13) to carrier (7) . If the original gears, the carrier assembly and the housing are used again, use the original thickness of shim pack (6) . If any of these parts are replaced, install a shim pack thickness of 1.73 mm (0.068 inch).Note: When you adjust the tooth contact pattern, make sure that there is a change in the thickness of shim pack (6) .
Tighten eight bolts (5) to a torque of 135 15 N m (100 11 lb ft).
When pinion housing (13) is fastened to carrier (7) , position bevel pinion (17) in a downward vertical position.
Lubricate bearings and install bearing cups on the differential bearings in order to protect the bearings.
With a lifting device, lower the differential into carrier (7) . Bevel gear (16) should be oriented next to dowel pin (23) . Check sleeve (3) for proper seating.
