- Measure distance (2) between the end of the clutch housing (A) and bearing inner race (B) with a straight edge and depth gauge. Measure at three locations and average the readings.
Shim Selection Formula:
- Select the proper 72 mm shim from the chart. Follow the example below, and use the measurements you made in steps 4 and 5:
- Add distance (2) (step 5) to distance (1) (step 4).
- From this number, subtract 0.95 (which is the midpoint of the flex range of the clutch housing bearing spring washer).
- Take this number and compare it to the available shim sizes in the chart.
- Try the 1.68 mm (0.0661 in.) shim.
(For example)
(1): 2.41 2.63
+ (2): 0.22 - 0.95
---------------- --------------
= 2.63 = 1.68
