This is the pulley that fits the current style SA1, WHERE BOTH DRIVE BANDS ARE ON THE SAME SIDE OF THE VEHICLE.

There is a short drive band that connects this Pulley to the Flywheel and a longer one that connects the Flywhel to the driving road wheel.

This 32mm diameter pulley has no screw fixing but is an interference fit onto the shaft. If it is not a tight fit you can use a drop of Loctite or super glue.

The shaft diameter is suitable for all current engines and almost all older engines but not the small MM1 stationary engine. No one makes those now.

You will have to measure and cut to length using a hack saw for all engines other than the SA1 Roadster.
