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
3
in 4 stages to the
specified torque so that the distance
b
between the special service tools
1
and
2
becomes equal.
9. Check the gap
a
between the pinion
4
and the special service tool
1
again.
TIP:
If there is no gap, the pinion shim(s) (T3) may
not have been removed.
10. Measure the gap between the pinion
4
and the special service tool
1
. When
measuring the gap, insert the end of the
thickness gauge straight into the gap at
the measurement point. Do not insert the
thickness gauge at an angle.
TIP:
9 Measure the gap at 4 points
c
,
d
,
e
, and
f
.
9 Note the measurement data in the shim-
ming check sheat.
11. Determine the gap average, and then
truncate it by dropping the numbers after
the 1/100 place without rounding.
12. Determine the pinion shim thickness (T3)
in the “Pinion shim (T3) selection tables”
according to the truncated average (M)
and the deviation (P) stamped on the
lower case.
