3. Install the washer (H) on the mainshaft.

4. Measure distance 1 between the end of the transmission housing and washer with a straight edge and

vernier caliper. Measure at three locations and average the reading.

5. Measure distance 2 between the end of the clutch housing (A) and bearing inner race (B) with a straight

6. Select the proper 72 mm shim from the chart. See Fig. 118 . Follow the example below, and use the

measurements you made in steps 4 and 5:

(Basic Formula)

1 + 2 - (0.8 + 0.11) = shim thickness (maximum)

1 + 2 - (0.8 + 0.17) = shim thickness (minimum)

Add Distance 2 (Step 5) To Distance 1 (Step 4).

0.8 mm (0.031 in): Spring washer, a dimension in the installation.

0.11 mm (0.004 in): Minimum thrust clearance.

0.17 mm (0.007 in): Maximum thrust clearance.

For Example:

2.32 + 0.15 - (0.8 + 0.11) = 1.56 mm (0.061 in.)

2.32 + 0.15 - (0.8 + 0.17) = 1.50 mm (0.059 in.)

Take the middle value of the minimum value and the maximum value, and select the 1.53
mm (0.060 in.) shim.
