that secure the pinion to the housing. Place the thrust washer and
differential side gear in the drive gear assembly.
Install the four differential spider pinion gears and thrust washers
on the differential spider and place the spider, including the gears,
in position on the drive gear assembly. Install the thrust washer and
differential side gear in the differential gear case. Line up the match-
ing numbers on the drive gear assembly and differential gear case so
that the numbers
are directly opposite each other. Place the two
assemblies
together.
Install the eight bolts that secure
the two
assemblies together and tighten them evenly. Lock the eight bolts
with locking wire.
Be sure that the differential side bearings are thoroughly
clean,
and apply a thin coating of grease on the bearings. Place a new
gasket on the right-hand side of the center housing. Position the
right-hand axle housing on the center housing. Install and tighten
the nuts. Position the differential assembly in the center housing with
the flat side of the drive gear facing the left-hand axle housing. Place
a new gasket on the center housing. Position the axle housing on the
center housing. Install and tighten the nuts.
Install the axle shafts in the housings. Install the gaskets and the
oil seal retainers on the bearing retainers.
Secure the brake shoe
brackets
to the bearing
retainers
with
two
cap screws
in each
bracket. Coat each axle housing flange with a light film of grease.
Position the gaskets on the axle housings.
Remove several of the shims of the shim pack previously used on
the bearing retainer, and place the remainder of the pack between
the brake plate and the bearing retainer. Hold the brake cross shaft
in position, and install the brake plate and bearing retainer assembly
on the axle housing. Rotation of one axle shaft should
now cause
the other shaft to rotate in the same direction. If it does not, more
shims must be removed.
Increase the shim pack thickness in steps of approximately 0.005
inch. It may be necessary to exchange thick shims for thin ones, or
vice versa, to produce the required addition.
The shim thickness
must be increased until the rotation of one shaft causes the other
to rotate in the opposite direction. By following this procedure, the
amount of end play in the axles will be held to the desired limits
(0.002 to 0.004 inch).
Install the hubs, seals, flat washers, nuts, and lock rings.
