SERViCE MANUAL
Paragraph 15
0.118 inch (3.0 mm) thick thrust disc (1—Fig. 16) on
each side gear, then starting with a friction plate (2)
alternate with friction disc (3) until five friction
plates and four friction discs are in place on each side
gear. Install side gear (16) assembly into differential
case
(17).
Install thrust washers (13) and differential
pinions
(15).
Install pinion shaft
(18)
through differen-
tial pinions and secure with roll pin (19). Then, in-
stall side gear
(14)
assembly in differential
case.
With
differential case standing on carrier bearing end, ap-
ply light hand pressure on the plates and measure
the distance between friction plate and end of case
as shown in Fig. 17. Record measurement and check
the clearance on opposite side, using a feeler gage
through hole in case as shown in Fig. 18. Clearance
(end play) of friction plates should be 0.0039-0.0078
inch (0.1-0.2 mm) for each side. If measurements are
not correct, change thickness of thrust plate (1—Fig.
16) as needed. Thrust plates are available in thick-
nesses of
0.110,0.114,
0.118, 0.122, 0.126 and 0.130 inch
(2.8,
2.9, 3.0, 3.1, 3.2 and 3.3 mm). Screw two guide
studs into case (17) and press ring gear (12) onto case.
Install roll pins (20 and 21) and cap screws
(11).
Tight-
en cap screws to a torque of
51
ft.-lbs. (69
N-m),
then
press lock plate (10) over bolt heads. Heat carrier
bearing cones in a bearing oven to a temperature of
250° F (120° C) and install on differential assembly.
WARNiNG: Always wear heat protective gioves
when handiing heated parts.

Ib remove the bevel drive pinion (8—Fig. 19),
remove lock plate
(1).
Remove nut
(2),
then drive the
bevel pinion shaft into left axle housing. Remove oil
seal (3), outer bearing cone (4) and spacer
(5).
Drive
shim spacer (6) and inner bearing cup (7) from hous-
ing, then remove outer bearing cup
(4).
Using a suita-
ble puller, remove inner bearing cone (7) from bevel
pinion shaft. Clean and inspect all parts and renew
as necessary. Bevel drive pinion (8) and ring gear
(12—Fig.
15
or 16) are available only as a matched set.
Before reinstalling bevel drive pinion, adjust
differential carrier bearing preload as follows: Install
a 0.47 inch (1.2 mm) thick shim spacer (2—Fig. 15)
in left axle housing (5) and install left carrier bear-
