Very high quality pulley for your two-stroke maxi scooter.
Should be replaced immediately if chipping occurs on the running surface, as this can severely affect the service life of the V-belt! This newer variant no longer has the old chrome plating, which chipped off after a while.
Installation instructions: Insert original washers correctly placed! Before tightening the crankshaft nut, always pull the V-belt into the back of the converter, otherwise you will only tighten the pulley against the V-belt and the pulley will not be pressed correctly with the variator on the cylinder bushing. The internal toothing, which is only used for centering, will otherwise rotate and could even cause damage to the crankshaft.
