7.Secure the lock nut with the stake washer.

8.Use a depth gauge to measure the distance from the end face of the input shaft/pinion gear to the mating sur- face of the bearing case. Subtract the “Design Cone Center Distance” from this distance to determine initial shim thickness (Fig. 32).

DESIGN CONE CENTER DISTANCE (distance from mating surface of axle support to end face of pinion gear):

1.870 + 0.002 in. (47.5 + 0.05 mm)

NOTE: Bearing case shims are available in 0.004 in. (0.1 mm) and 0.008 in. (0.2 mm) thickness.

9.Coat new O-rings with grease and install the bearing case in the gear case. Place shims on the gear case and temporarily install gear case assembly into axle case. Tighten mounting nuts and screws from 35 to 41 ft-lb (47 to 56 N--m).

10.Insert a screwdriver through the drain plug hole to hold ring gear and measure the pinion gear to ring gear backlash (Fig. 33).

PINION GEAR TO RING GEAR BACKLASH: 0.004 to 0.016 in. (0.10 to 0.40 mm)

11.Adjust backlash by increasing or reducing gear case shim thickness.

12.Check pinion gear to ring gear engagement (see Pin- ion Gear to Ring Gear Engagement in this section of this manual).

13.Place the correct combination of shims on the gear case. Tighten mounting nuts and screws from 35 to 41 ft-lb (47 to 56 N--m).

14.Install retaining rings and driven gear on input shaft/ pinion gear.

15.If the drive gear (on drive motor shaft) was removed, install the retaining rings and drive gear on the motor shaft.

16.Use a new gasket and install the cover plate.
