5. Measure distance @ betlveen the end of the clutch
housing and bearing inner race.
NOTE:
. Use a straight edge and depth gauge.
a Measure at three locations and average the read-
Ings.
Select the prcpet 72 mm thrust shim from the chart
by using the formula below.
NOTE: Use only one 72 mm thrust shim.
Shim Sslsction Formula:
From the measurements you made in steps 4 and 5:-1. Add distance @ (step 5lto distance @ (step 4).
-2. From this number. subtract 0.93 (which is the
midpoint of the flex range of the clutch housing
bearing spring washerl.
-3. Take this number and compare it to the avaif
able shim sizes in the chart.
