angles to it (Fig. 331. "Rock" the ring gear and
note the movement of the gear as registered on
the dial indicator. The backlash or play of the
ring gear should be .002" to .006"..004" desired.
FIGURE 33— Checking Ring Gear and
Pinion Backlash
Adjust the backlash as follows: To increase
backlash, install a thinner shim on the ring
gear side and a thicker shim on the opposite
side; to decrease backlash, reverse the proce-
dure. However, do not change the total thick-
ness of the shims.
For example: The side play was removed with
.090" shims on each side totaling .180". The
backlash is checked and found to be .011".
To correct the backlash, add .006" to the
shim on the ring gear side and subtract .006"
shim from the opposite side. This will result
in a .096" shim on the ring gear side and
.084" shim on the other side. The backlash
will be .005". The total shim thickness
remains .180".
Preloading Differential Side Bearings
The rear axle differential bearings are pre-
loaded to compensate for the heat and loads
during operation. The correct preload is .004"
to .008".
The side bearings may be preloaded in two
ways; by installing a .004" to .008" thicker
shim on one side or by increasing both shims in
thickness so the total thickness of the shims
is .004" to .008" greater than the thickness
with the side play removed.
Differential Assembly Installation
Assemble the side bearing cups and shims on the
side hearings. The bearing cups should com-
pletely cover the rollers of the side bearings.
Lower the assembly into the axle housing until
the bottom edge of the bearing cups and shims
are started in the bearing bore (Fig. 341.
FIGURE 34— Install the Differential Assembly
Keep the differential assembly square in the
housing and push it down as far as possible.
Using a soft hammer, tap the outer edge of the
bearing cups until seated in the housing.
CAUTION: Do not distort the shims by
hammering them into the housing.
Install the bearing caps and tighten (105 to
110 foot pounds torque "Hornet" and 55 to 60
foot pounds
