The clutch on your golf cart is a vital tool in making things move. There are actually two of them, and the belt hangs between the two. As the engine spins up the front clutch, it starts to suck in. This is thanks to centrifugal force and internal weights that expand with increasing RPM. As this happens, the belt is pulled farther and farther down into the secondary clutch. This is what makes the wheels turn. If you have a problem with that drive clutch, getting it off is not so easy without a Yamaha Primary Clutch Puller Bolt.Your clutch is a press fit. This does not mean that you need some fancy tool to install it too. The average golf cart hold-down bolt will do the job with no problem.
