Remove indicator and differential assembly from

housing.

Remove master bearings from hubs and set aside.

Assemble ring gear to case.

Fig. 53

Note :

Use new ring gear screws.

Draw up screws alternately and evenly. Torque ring

gear screws to specification.

Assemble master differential bearing onto case hubs.

Place differential assembly into housing. Set up dial

indicator and locate lip of indicator on flat surface of

one of the ring gear screws.

Force the differential case assembly (with ring gear)

away from the pinion gear. With force still applied to

the differential case, set indicator at (0) zero.

Fig. 54

Now push the differential case assembly to the other

side.

Force the differential case assembly and ring gear

to mesh with the pinion gear. Rock ring gear to allow

the teeth of the gear to mesh. Take reading.

Repeat until the same reading is obtained.

Record this as measurement

Remove master bearings.

Assemble the shim pack using the figure determined in A,B,&C adjusting the packs as described below.

RING GEAR SIDE :

Assemble shim pack to measurement

- 0.125 mm. or B - 0.005"

OPPOSITE SIDE OF RING GEAR :

Assemble shim pack to measurement

. Add 0.20 mm or 0.008" for differential bearing preload and backlash.
