ing cup (1). Install differential assembly in left axle
housing. Hold right carrier bearing cup on bearing
cone and measure distance between outer edge of
cup and left axle housing flange as shown in Fig. 20.
Refer to Fig. 21 and measure distance between right
axle housing flange and carrier bearing seat (shoul-
der).
Subtract the first measurement from the sec-
ond measurement. Select a shim washer
(25—Fig.
15)
with thickness equal to the difference between the
two measurements. Shim washers are available in
twenty thicknesses from 0.020-0.071 inch (0.5 to 1.8
mm).
Install the selected shim washer (25) and car-
rier bearing cup in right axle housing. Remove
differential assembly and wrap a cord around
differential case. Attach a spring scale to loose end
of cord. Reinstall differential assembly with spring
scale protruding through bevel pinion shaft opening
as shown in
Fig.
22. Install right axle housing assem-
bly and secure with four cap screws (22—Fig. 15)
spaced at 90 degree intervals. Tighten the four cap
screws to a torque of 44-52 ft.-lbs. (60-70 N-m). Pull
on spring scale and check rolling resistance of
differential assembly. Amount of pull on scale should
be between 4.4 and 16.5 lbs. (2.0 and 7.5 kg). If not,
remove right axle housing, remove carrier bearing

cup (26) and install a thicker shim washer (25) to in-
crease or a thinner shim washer to decrease preload
on bearings. Reassemble and reinstall right axle hous-
ing and recheck preload.
When preload is correct, measure distance *'A**
from end of bevel drive pinion bore to differential
case as shown in Fig. 23. Record distance *'A*\ Re-
move right axle housing and differential assembly.
Install inner pinion shaft bearing cup. Hold pinion
shaft bearing cone in position with a flat steel plate
and measure distance
**B*'
as shown in Fig. 24. Rec-
ord distance
'*B*'.
Measure diameter of differential
case and divide by 2. This will be the case radius or
distance (*'D"-Fig. 25). Record distance **D". Dis-
tance '*F'' is the distance from inner bearing cone
to the center of the differential case. Distance '*A"
plus distance
**D**
minus distance
**B*'
will result in
distance 'T**. Distance
*'F'*
minus the metric dimen-
sion
**E*'
etched in millimeters on end of pinion shaft
gear will give the metric shim spacer thickness to be
installed at
(S)
between inner bearing cup
(7—Fig.
19)
and bearing cup seat (shoulder) in pinion housing.
Shim spacers (6) are available in thicknesses of 0.035
to 0.059 inch (0.9 to 1.5 mm) in 0.002 inch (0.05 mm)
increments.
