Adjust the drive pinion mounting distance as
follows:
a.
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.
Install gauge plate 5-8840-2166-0 (3), inner
pilot 5-8840-0129-0 (2), stud and nut 5-8840-
0127-0 (4) and outer pilot 5-8840-2085-0 (1)

d.
Set the dial indicator 5-8840-0126-0 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.

e.
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 deflection. At this point,
once again set the dial indicator to “0".
Repeat the procedure to verify the “0"
setting.

f.
After the ZERO setting is obtained, rotate the
gauging arbor until the dial indicator rod does
not touch the gauging plate. Record the
number the dial indicator needle points to.

g.
Record the pinion depth code on the head of
the drive pinion. 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".
