NOTE
Always replace the bearing cones and cups as a set.
1. Support the inner race of the inner bearing cone (11).
Press the pinion shaft (12) into the bearing cone with
the bearing taper facing away from the pinion gear.
2. Press the bearing cups (2 and 10) in the pinion
housing (8) with the taper facing outward.
3. Install the bearing gear and pinion shaft (12) and
inner bearing cone (11) assembly in the pinion
housing (8).
4. Install the collapsible spacer (9) on pinion shaft (12).
Position the sleeve against the bearing inner race.
IMPORTANT
Do not collapse the collapsible spacer when
installing the outer bearing cone. If collapsed at this
time, a new spacer must be installed.
5. Install the outer bearing cone (3) over the bearing
gear and pinion shaft (12). Applying pressure to the
bearing inner race only, press the bearing into the
housing until it just contacts the collapsible spacer
(9).
NOTE
Lubricate all O-rings prior to assembly.
6. Install O-ring (7) in spacer (4). Install spacer in the
housing, positioning the O-ring against the outer
bearing cone (3).
7. Install, but do not tighten, the elastic stop nut (5).
Figure 5-71
8. While applying slow and steadily increasing pressure
on the torque wrench, tighten the elastic stop nut (16)
until a break-away torque of 4.5—6.3 lb-in.
(0.5—0.7 N·m) is obtained.
9. Install the seal (6) in the pinion housing (8).
NOTE
Lubricate all O-rings prior to assembly.
10. Install O-ring (13) on pinion housing (8).
IMPORTANT
• If the original pinion shaft was reused, proceed to
step 11.
• If a new matched input bevel pinion and ring gear
was installed, proceed to “Input Bevel Pinion and
Ring Gear Clearance Adjustment” on page 5-75.
11. Install the input bevel pinion assembly (2—12) and
shims (14) on the axle assembly (15). Use the same
thickness of shims as recorded during disassembly.
12. Apply Loctite 242 (Blue) to screws (1) before
assembly. Install screws and tighten to 37 lb-ft
(51 N·m).
