REAR AXLE 11 - 25
18. If the micrometer reading shows that the pinion setting
is incorrect (more than .002" plus or minus from the
figures given) shims equaling the difference must either
be added to or taken from the shim pack between the
rear bearing cup and housing. Shims are available in
.003", .005" and .010" thicknesses. When changing
shim pack, measure each shim separately , replace pin-
ion and pinion depth gauge and recheck before proceed-
ing further.
19. After correct pinion setting has been obtained, and with
drive pinion in position, place original shims or new
ones of equal thickness on shaft, measuring each shim
separately.
20. Install drive pinion front bearing cone and rolls and
pinion using tool J-1570.
21. Install companion flange, washer and nut on front end
of pinion shaft and holding flange with J-2637 holding
tool, tighten pinion nut to 180-220 foot pounds.
22. Use scale on J-2637 holding tool and check torque
required to turn pinion. Disregarding starting torque,
turning torque should be from 10 to 20 inch pounds. If
more or less than this, shims will have to be added to or
taken from front shim pack. Shims in thicknesses of
.003", .005", .010" and .030" are available.
23. When proper torque is obtained, remove pinion nut and
washer and take off companion flange.
24. Place oil slinger and wick on pinion and Install new
gasket in counter-bore at front of housing. Place new oil
seal in housing and Install with rear face seated against
gasket.
25. ReInstall companion flange, washer an d nut, torquing
nut to 180-220 foot pounds.
26. Inspect differential bearing cone and rolls and cups as
well as the bearing bores in the housing and be sure they
are clean; place cups on rollers and lubricate ; Install
differential assembly in housing
27. Place bearing caps in their proper positions according to
markings, and tighten bolts finger tight.
28. Insert two screwdrivers between the bearing cup and the
housing on the side opposite the drive gear, and move the
differential and drive gear away from the pinion until the
opposite bearing cu. firmly seated against housing. Mosii
screwdrivers t o drive gear side, force differential and gear
over until drive gear teeth contact pinion.
29. From shim requirements shown by indicator reading
(paragraph 8), place shims between bearing cups and
housing, forcin g the m in on both sides so as to use total
amount and have gear rotate with no backlash, Figure 51.

30. Take out differential assembly and drive gear, keeping
shims for each side in a separate pack. With bearing
puller, remove bearing cones from differential case and
Install shim packs on their respective hubs, placing addi-
tional shims totaling .015" on the right hub to compen-
sate for housing spread and gear tooth backlash. Install
differential bearing cone and rolls on hubs, using tool
J-2646 making sure hubs, bearings and shims are clean.
Lubricate bearings with axle lubricant.
