Inspection Adjust of the clearance of
the Output shaft Bearings
The clearance the output shaft bearing is controlled
by the size of the snap ring that holds
the bearings in the bearing cage. The snap
rings are available in increments of 0.003-inch
(0.076 mm). Install the snap ring which results in
an clearance of 0.001-0.004-inch (0.025-0.102
mm).
1. Place the output shaft and the bearing cage
assembly into a vise with soft metal covers
on the jaws of the vise.
2. Use an installation tool to install the fork or
flange in the output shaft. Do not use the nut
to draw the fork in the output shaft. Do not
install the oil seal at this time.
3.Install the nut that fastens the fork or flange to
the output shaft. Place a holding tool on the fork
or flange and tighten the nut to the specified
torque. See the Section 8.
4.Push the fork or flange toward the cage and rotate
the shaft in each direction to verify that the
bearings are correctly installed.
5. Install a dial indicator so that the base of the indicator
is on the mounting flange of the cage.
The pointer of the indicator must touch the fork
or flange end of the output shaft. Set the dial indicator
to ZERO. Figure 5.92.

Assembly and Installation
6.Place pry bars under the fork or flange and
push the fork or flange away from the cage.
Record the reading on the dial indicator. The
reading must be 0.001-0.004-inch (0.025-
0.102 mm). The reading is the measurement
of the clearance on the output bearing.
• If the clearance reading is not 0.001-0.004inch
(0.025-0.102 mm), remove and replace
the snap ring that fastens the bearings in the
cage. Install a thinner snap ring to increase
the clearance. Install a thicker snap ring to decrease
the clearance. Figure 5.93.
7.Remove the nut that fastens the fork or flange
to the output shaft. Use the correct puller tool
to remove the fork.

SNAP RING
To increase the clearance, install a thinner snap ring.
To decrease the clearance, install a thicker snap ring.

Installation Unitized Pinion Seal
1. Remove the old seal. Do not damage the
bearing cage seal surface area. Do not touch
or allow dirt or grease to contaminate the
sealing surface areas or the adjacent bearings.
2. Inspect the bearing cage seal area for damage
that could cause lubricant leaks after you install
the seal. Use emery paper or an equivalent
product to remove scratches, nicks or burrs.
