6. Place the pinion facing upward and hold
it in the upright position.
7. Turn the drive shaft 10 times or more to
seat the taper roller bearing.
8. Tighten the bolts
c
in 4 stages to the
specified torque so that the distance
e
between the base
a
and the plate
b
of
the special service tools
3
become
equal.
9. Recheck the gap
d
between the special
service tool 1 and the pinion 2 .
TIP:
If there is no gap, the pinion shims may not
have been removed.
10. Measure the gap between the special
service tool
1
and the pinion
2
. When
measuring the gap, insert the end of the
thickness gauge straight into the gap at
the measuring point. Do not insert the
thickness gauge at an angle.
TIP:
• Measure the gap at 4 points
f
,
g
,
h
, and
k
.
• Write down the measurement data in the
shimming check sheet.
11. Determine the gap average, and then
round down the average to the 1/100
place.
Example:
12. Determine the pinion shim thickness (T3)
in the “Pinion shim (T3) selection tables”
according to the round-down average
(M) and the deviation “P” stamped on the
lower case.
