6. Select the proper 78 mm thrust shim from the chart by using the formula below.

Note: Use only one 78 mm thrust shim.

Shim Selection Formula:
From the measurements made in steps 4 and 5:
– 1. Add distance C (step 5) to B (step 4).
– 2. From this number, subtract 0.93 (which is the mid – point of the flex range of the clutch housing bearing spring washer).
– 3. Take this number and compare it to the available shim sizes in the chart.
