. Adjusting Backlash
1.
Divide the ring gear into quarter-sect and apply the
marks onto the divided portions with suitable marker.
2. Set a dial indicator to one
of
the marked po
in
ts
so that the feeler comes in contact at right angles
with the ring gear teeth.
3. Adjust the backlash between the ring gear and drive
pinion and the bearing preload as follows.
a) Tighten the bearing adjuster
of
the back side
of
the ring gear so that the backlash comes within
specification.

b) Check the backlash
of
the other marked points.
Note:
• Maximum difference

c) Check the preload on the side bearings by mea-
suring the distance between
both
pilot sections
on
bearing cap.
If
the preload
is
out
of
specifi-
cation, adjust the preload by turning the opposite
side bearing adjuster.

d) After adjusting the preload, recheck the backlash .
