1	Clutch Assembly Procedure: Using an inside caliper, measure the height of the clutch assembly in the location shown and record the results. Repeat the process in 2 additional locations, 120 degrees from each other. The average of the 3 measurements is the clutch assembly height. 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. 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. NOTE: A variety of shims are available to properly adjust the clearance height of the clutch assembly. An inside micrometer may also be used to measure the clutch assembly height.
