for Clutch Spacer Washer
During the slip-clutch adjustment it may be necessary to add an extra spacer washer, or remove the
existing spacer washer from directly under the castle nut used to adjust the slip clutch. The extra spacer
washer is provided in the GSM 85(A) Mounting Hardware Kit (011-01028-XX). If this part is not
available, use an AN960-616 washer.
