Note: One hole on adjusting nut = approximately
0.003” change in backlash. Left and right
nuts MUST be turned the same amount AND
in the same direction. The final direction of
rotation MUST be in the tightening direction,
to loosen a nut 1-hole, back off 2-holes and
then tighten 1 hole. The ring gear should be
rotated any time the nuts are being adjusted.
10: Loosen the right side nut.
11: Tighten the left nut until all backlash is removed
from the ring and pinion gear.
12: Tighten the right nut until a case spread of 0.010
inch (0.254 mm) is indicated on the dial indicator.
Note: If new ring and pinion gears are used, refer to
the recommended backlash that is supplied
with the gear set
13: Measure the backlash. It should be within 0.002
inch (0.05 mm) of the original measurement taken
on disassembly or the recommended setting
for new gears. If it is out of specification then
readjust the bearings as follows:
•
To increase backlash, loosen the left spanner nut
and then tighten the right spanner nut the same
amount.
•
To decrease backlash, loosen the right spanner
nut and then tighten the left spanner nut the same
amount.
14: Apply gear marking compound on both sides of 7
to 10 teeth on the ring gear.
15: While applying resistance to the pinion shaft,
rotate the ring gear back and forth (not full
revolutions) until a clear contact pattern is shown.
Compare the contact pattern to the illustration on
the following page and reshim the pinion housing
or adjust the backlash as indicated on the
illustration . If the pinion housing is reshimed the
backlash must be reset. Go back and repeat ALL
procedures in setting the backlash.
16:
Tighten the bearing cap bolts to torque specified
in the Hardware Torque table at the end of this
section.
17:
On final assembly, then pinion nust should be
tightened to torque specified in the Hardware
Torque table at the end of this section.
