17.Assemble the lock pin. Drive the pin to the approxi-
mate center location of the pinion mate shaft. Peen the
metal of the case to lock the pin in place (Fig. 49).
18.Position the ring gear onto the differential case and
thread new cap screws into the ring gear. Tighten the
screws, alternating back and forth across the gear to al-
low the gear to be pulled evenly into place. Torque cap
screws from 45 to 65 ft-lb (61 to 88 N−m) to secure as-
sembly (Fig. 50).
19.When installing new differential bearings, reuse the
original shims or use new shims of the same thickness.
Press the new differential bearings onto the differential
case. If a new differential case is being installed, start
with a 0.020 inch (0.50 mm) pack of shims under each
differential bearing (Fig. 51).
NOTE: Shims are available in 0.003 in. (0.08 mm),
0.005 in. (0.13 mm), 0.010 in. (0.25 mm) and 0.030 in.
(0.76 mm) thickness.
