Assembly
1. Use new gaskets and seals when reassembling axle.
2. Assemble differential case (Fig. 12):
A. Assemble differential. Use medium strength Loc-
tite on bolts (Item 7) and tighten evenly to a torque
of 20 - 24 ft-lb (270-330 Kg-Cm).
B. Assemble pinion gear (Item 30) and bearing case
(Item 38). Tighten bearing nut (Item 34) to pre-load
tapered roller bearings. Tighten so pinion shaft will
rotate with 2 - 5.5 in-lb (2.0 - 6.5 Kg-Cm) of torque.
Bend washer (Item 33) to prevent nut from loosen-
ing.
C. Adjust tooth contact of bevel gear (Item 6) to
pinion (Item 30). Use shims (Item 29) to make good
contact with light load between bevel gear and pinion
(Fig. 13).
D. After adjusting tooth contact, use shims (Item 5)
to make backlash 0.003 - 0.01 in. (0.08 - 0.25 mm).
Check backlash through plug hole (Item 26) with a
dial indicator.
