Assembly and Installation
44 MAINTENANCE MANUAL
5. If removed, install the outer bearing cap for
the drive pinion.
A. Place the differential caser in the press so
that the bearing caps of the differential stay
toward the bottom of the press. Place sup-
ports under the differential case, so that the
differential is level.
B. Place the outer bearing cap for the drive pin-
ion into the bore of the differential case.
C. Use a sleeve or a installation tool and a
press to install the cap. Press the cap into
the differential case until the bottom of the
cap touches the bottom of the bore. If a
press is not available, use a sleeve, a brass
drift or a installation tool and a hammer to
install the cap. Figure 5.8.
Installation Drive Pinion Assembly
1. Place the drive pinion into the differential
case so that the pinion is through the inner
and the outer bearing caps.
2. Place the differential case in the press so
that the bearing caps of the differential stay
toward the bottom of the press. Place sup-
ports under the differential case so that the
case is level. Place a support under the head
of the drive pinion so that the inner bearing
cone on the pinion shaft touches the inner
bearing cap in the differential case.
3. Place the outer bearing cone in the pinion
shaft
4. Use a press and a sleeve to install the bear-
ing cone in the pinion. Apply no more than
two tons (1814 kg) of force to verify that the
bearing cone is correctly installed. Figure 5.9.
Adjustment Drive Pinion Bearing Preload
NOTE:
If the depth of the drive pinion was changed,
then the amount of the change must be
added or subtracted to the thickness of the
spacer between the outer bearing cap and
the helical driven gear.
After you obtain the correct gear tooth con-
tact pattern and the correct shim pack thick-
ness,youmust adjustthe bearingpreload on
the drive pinion. The preload is controlled by
the thickness of the spacer between the helical
driven gear and the outer bearing cone. Figure
5.10.
