Drive Pinion and Bearing Cage Reassembly
To reassemble the drive pinion
and bearing cage, use the
following procedure:
1.
Place the bearing cage in a
press. Support the bearing
cage between metal or
wooden blocks.
2.
Press the bearing cup into
the bore of the bearing
cage until the cup is flat
against the bottom of the
bore. Use a sleeve of the
correct size to install the
bearing cup.
3.
Put the drive pinion in a
press with the gear head
(teeth) toward the bottom.
4.
Press the inner bearing
cone onto the shaft of the
drive pinion until the cone
is flat against the gear
head. Use a sleeve against
the bearing inner race if
necessary.
5.
To install one-piece spigot
bearing assemblies, put
the drive pinion in a press,
gear head teeth toward the
top. Press the spigot
bearing onto the end of the
drive pinion until the
bearing is flat against the
gear head. Install the snap
ring to secure the bearing.
Be sure the snap ring is
securely seated.
6.
Apply axle lubricant on the
bearing cups in the cage
and bearing cones.
7.
Install the drive pinion into
the bearing cage.
8.
Install the bearing
spacer(s) onto the pinion
shaft against the inner
bearing cone (
