Shimming
• Shimming is not required if the backlash is
within specification.
• Shimming is required when assembling the
original inner parts and a new lower case.
• Shimming is required when replacing the
pinion, forward gear, reverse gear, bear-
ings, shaft, or propeller shaft housing.
Selecting the pinion shim
Select the pinion shims using the measure-
ment(s) and calculation formula.
1.
Install the special service tools
1
and
2
onto the drive shaft assembly
3
and
taper roller bearing outer race
4
.
TIP:
• Install the drive shaft assembly
3
so that
the shaft is centered in the hole.
• Tighten the wing nuts
a
1/4 turn after they
contact the special service tool
2
.
• Make sure that the distance
b
between the
special service tools
1
and
2
is equal.
• Make sure that the special service tool
1
and drive shaft
3
are parallel.
2.
Install the pinion
5
, and then tighten the
nut
6
to the specified torque.
3.
Measure the distance (M3) between the
special service tool
1
and the pinion
5
at 4 points, and then calculate the aver-
age.
4.
Calculate the pinion shim thickness (T3).
