Set a horizontal type dial indicator on the ring gear
through the
filler hole.
Tum the ring gear back and forth to read backlash.
STANDARD:
0.05 - 0.25 mm (0.002 - 0.010 in)
SERVICE LIMIT: 0.4
mm
(0.02
in)
Remove the dial indicator. Turn the ring gear 120
0
and
measure backlash. Repeal this procedure once more.
Compare the difference of the three measurements.

If the difference in measurements exceeds the service
limit, it indicates that the bearing is not installed
squarely, or the case is deformed.
Inspect the bearings and case.
If
th
e backlash
is
excessive, replace the ring gear left
r------------------,
side shim with a thinner one.
If the backlash is too small, replace
the
ring gear left
side shim with a th icker one.
The backlash is changed by about 0.06 mm (0.00 2 in)
when the thickness of
the
shim is changed
by
0.10 mm
(0.004 in).
NOTE-
Twenty-three different thickness shims are available
from the thinnest
(0.50 mm thickness: A) shim
to
the
thickest
(1.60 mm thickness:
W)
in intervals
of
0.05 mm.
