Select the prcpe( 72 mm thrust shim from the chart
by using the formula below.
NOTE: Use only one 72 mm thrust shim
Shim Selection Formula:
From the measurements you made in steps 4 and 5:
- 1. Add distance @ (step 5) to distance @ (step 4).
-2. Frcm this number. subtract 0.93 (which is the
midpoint ot the flex range of the clutch housing
bearing spring washer).
-3. Take this number and compare it to the avail-
able shim sizes in the chart.
