(4) Gauge Plate: 5–8840–2087–0

4. 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.

5. 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”.
Repeat the procedure to verify the “0” setting.

6. After the ZERO setting is obtained, rotate the

gauging arbor until the dial indicator rod does not
touch the gauging plate.

7. 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 indi-
cates 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 ex-
amination reveals pinion depth code “0”, the pin-
ion is “nominal”.
