PART: Securistat Powerbloc Snowmobile Drive Clutch Centrifugal Blocks (set of three 3) Includes set-up manual and decals
PART NUMBER: X9..
These centrifugal blocks are the heart of the clutch. The steel cap drives the loose half pulley in rotation through them and, under cetrifugal force, they push the latter towards the fixed half-pulley, urging the belt to ride along increasing circumfrences. By carefully choosing the spring and by adding, if necessary, appropriate weight in the blocks, optimum engine performance can be reached.
