Select the proper 78 mm shim from the chan by
using the formula below.
Shim S€lection Formula:
From the measurements you made in steps 4 and 5:-1. Add distance @ (step 5) to distance @ (step 4).
-2. From this number. subtract 0.93 (which is the
midpoint of 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.
(For example)
A: 2.39 2.61
+ Bi O.22 - 0.93
= 2.61= 1.68
Try the 1.68 mm (0.0661 in) shim.
