Need a clutch for your Golf Cart, ATV, 6 or 8 Wheeler? Here's your clutch. It's the Comet 780 and is offered in two different belt widths. A 1" wide model for use on Club Car and Hyundia golf carts up to 16HP. And a 1 3/16" wide model for Ezgo, Yamaha and Club Car* golf carts using 8-23HP. For use on Briggs, Honda, Vanguard, Kohler, Kawasaki or any other engines with a 1 inch straight crankshaft with 1/4" key. Rated to 6,000 RPM and 23 HP This clutch is 7.25 inches in diameter with steel rollers and weights which gives the CPP780 a positive but smooth engagement and a faster shift profile than puck style clutches. The 780 is a maintenance free clutch and the design makes it very durable. This clutch has been tested and abused by CPP and passed with flying colors. Because this clutch is built for Cart Parts Plus for use on a 4 cycle engine from 8-23 HP being used in a golf cart. It is setup perfect right out of the box with engagement at approximately 1700 RPM and a 3100 RPM shift point. No tuning is required just bolt it on. This is not a clutch made for something else that works on golf carts, it was tested and calibrated on golf carts. Capable of both velvet smooth starts or slam you in the seat performance. After all isn't that why you wanted the Big Block in the first place.
