Drive Pinion

Height Adjustment

NOTE: If the drive pinion and ring gear are replaced

(always as a set), the height has to be adjusted.

Select the proper shim as follows:

First, calculate the difference in size between the old

shim and the new pinion.

The last one of the numbers (see ill.) on each pinion is the

plus (+) or minus (-) tolerance in thousands of a millime-

ter. So, a pinion with +20 is 0.02 mm larger and a pinion

with - 20 is 0.02 mm smaller.

1. If the number on the old pinion is a plus (+), add it

to the old shim thickness. If it is a minus (-), sub-

tract it from the old shim thickness.

2. If the number on the new pinion is a plus (+), sub-

tract it from the number you got in step 1. If it is a

minus (-), add it to the step 1 number.

3. Select the shim that is closest (but not more than)

the final number you got from steps 1 and 2.

Example 1:

Old shim: 2.00 mm thickness

Old pinion: +20 (0.02 mm)

New pinion: -10 (-0.01 mm)

2.00
+
0.02
+
0.01
=
2.03

Select the 2.03 mm (0.0799 in) new shim.

Example 2:

Old shim: 1.70 mm thickness

Old pinion: -10 (-0.01 mm)

New pinion: -20 (-0.02 mm)

1.70-0.01 + 0.02 = 1.71

Select the 1.70 mm (0.0669 in) new shim.
