Clutch center securing kit featuring 57-1047 nut, 57-1046 tab washer, and 57-2279 cupped washer.
This kit is used to tie the clutch hub, sprocket, and clutch center together.
The cupped washer forms an abutment for the nut to tighten against. The tab washer is used to retain the nut in place once the nut is tightened to the proper torque specification.
A clutch locking tool is useful for holding the clutch center stationary whilst applying force to the nut to achieve proper torque specification.
