Clutch Assembly

Procedure:

1. Using an inside caliper, measure the height of the

clutch assembly in the location shown and record
the results.

2. Repeat the process in 2 additional locations, 120

degrees from each other.

3. The average of the 3 measurements is the clutch

assembly height.

4. A 3.1 mm (0.122 in) clearance +/- 0.1 mm (0.004

in) is necessary between the clutch pack height and
the assembly height. It may be necessary to replace
the clutch shim with a thicker shim or a thinner
shim, to achieve the proper clearance in the clutch.

5. Subtract the clutch pack height from the clutch

assembly height. The difference should be between
3.0 mm (0.118 in) and 3.2 mm (0.126 in)
clearance.
