Use the correctly sized spacer. Do not use shim stock or
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.
3. 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
bearing 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 following
methods:
Weld: Place a weld bead around the inside of
the cup, when the weld cools the cup will fall
out.
Hammer: Use slipper to get under the cup and
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
bearing 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.
