grind spacers. These practices can lead to loss of bearing
preload and gear or bearing failure.
To prevent bearing damage, use suitable sleeve that only
contacts the inner race of bearing cone.
3. Use a press sleeve to install the inner bearing cone
and pilot bearing, if used, onto the pinion. Apply
pressure until the bottom of the cone touches the
shoulder of the pinion. Apply lubricant to the cone of
the bearing.
4. If removed, install the inner and outer bearing cups
into the carrier.
a. To install the inner bearing cup, place the carrier
in a press with the bottom of the carrier facing
up.
b. Place the cup in the bore, use a sleeve or bear-
ing driver tool to press the cup until it is fully
seated. Use a feeler gage to make sure the cup
is fully seated.
c. If replacement of the output shaft side gear
bearing cup is necessary, use either of the fol-
lowing methods:
Weld: Place a weld bead around the inside of
the cup, when the weld cools the cup will fall
out.
Hammer: Use a rolling head prybar to get under
the cup and then, with a hammer and drift from
the back side of carrier, tap out bearing cup.
d. To install the outer bearing cup, place the carrier
in a press with the top of the carrier facing up.
e. Place the cup in the bore, use a sleeve or bear-
ing driver tool to press the cup until it is fully
seated. Use a feeler gage to make sure the cup
is fully seated.
Note: If a press is not available, use a sleeve or bearing driver
and a hammer to install the cups.
5. Place the pinion on a 6” x 6” x 6” block of wood and
lower the carrier over the pinion.
6. Install the pinion spacer.
