greater than specified, make certain that dirt or burrs
are not holding the ring gear in a cocked position on
the case and that the bolts are evenly torqued.
Figure 48-27 Installing Differential Side Bearings
1 I. In.stall side bearings using installer J-22919 and
drive handle J-8092. Support opposite side of case on
pilot J-2241-1 1 to prevent bearing damage. See Fig-
ure 4B-27.
12. Determine differential side bearing preload and
backlash as follows:
a. Position differential case assembly less side bear-
ing shims into the side bearing bores of the carrier.
See Figure 4B-28.
Figure 48.28 Installing Differential Case Assembly
Using two sets of feeler gauges, insert feeler stock
b.
of suffcent thickness between each bearing outer
race and the carrier to remove all end play. Make
certain the feeler stock is pushed to the bottom of the
bearing bores. See Figure 4B-29.
c. Mount dial indicator J-8001 on carrier so indicator
stem is at right angles to a tooth on the ring gear. See
Figure 4B-29.
d. Adjust feeler gauge thickness from side to side
until ring gear backlash is ,004" to .OO8" (.005" is
desired).
e. With zero end play and correct backlash estab-
lished, remove feeler gauge packs, determine thick-
ness of shims required and add ,002" to each shim
pack to provide side bearing preload.
f. Remove case assembly and both side bearings us-
ing J-22588 with adapter leg J-22939 and pilot J-
2241-l 1.
g. Install shim packs with respective side bearing
