UEI • Adjustment of drive pinion mounting distance
a 1) Apply gear oil to the inner and outer drive
pinion bearing.
Clean the pinion setting gauge set.
Then
install the gauge set together with
the inner and outer bearings (Fig. 48-31 ).

2) Clean the side bearing bores. Install the
dial indicator with the discs and arbor (Fig.
48-32).
Install and tighten the bearing
caps to the specified torque.

3) Set the dial indicator to "0". Place it on the
mounting post of the gauging arbor with
the contact button touching the indicator
pad. Force the dial indicator downward
until the needle has made a half turn
clockwise. Tighten down the dial indicator
in this position (Fig. 48-33).

4) Position the plunger on the gauge plate.
Move the gauging arbor slowly back and
forth and locate the position at which the
dial indicator shows the greatest
defection. At this point, once again set the
dial indicator to "0" (Fig. 48-34).
Repeat
the procedure to verify the "0"
setting.
•

5) After the ZERO setting is obtained, rotate
the gauging arbor
until the dial indicator
rod does
not touch the gauging plate (Fig.
48-35).
Record the number the
dial indicator
needle points to.
Example = Di:;i indicator reading of 0.085
Fig. 48-35
6) Record the pinion depth code on the head
of the drive pinion (Fig. 48-36).
The
number indicates a necessary change
in the pinion mounting distance. A
plus
number indicates the need for a greater
mounting distance (which can be achieved
by decreasing the shim thickness). A minus
number indicates the need for a smaller
mounting distance (which can be achieved
by increasing the shim thickness).
If
examination reveals pinion depth code "0",
the pinion is "nominal".

1®.1 • Place the shim on the drive pinion, then install
the inner bearing onto the pinion using an
installer and a press (Fig. 48-37).
Installer: J-6133-01
