This pulley is of great help if you have wobble problems with your original pulley.

Sometimes the end of the crankshaft where the pulley sits is severely worn

and the original pulleys will no longer be tight.

This pulley is slotted so that once it is slid into position and the locking pin is in place

tightened with an Allen bolt.

This aluminum pulley also has grooves on each side to prevent the belt from slipping
