The Columbia and Yamaha Drive Belt is the rubber strap-looking thing connecting the primary or drive clutch to the secondary or driven clutch. Your caddie uses these two pulleys to run the whole shebang. The drive clutch uses weights and centrifugal force to collapse and draw together as the engine spins faster and faster. As this happens, it causes the belt to get pulled toward the top of the primary. Well, as some guy named Newton once said, every action has an equal and opposite reaction. As the belt pulls up on one clutch, it draws down on the driven clutch. This is the standard action of the cart, but the high friction it creates wears belts out fast.This golf cart drive belt will work for Columbia, Harley Davidson, and Yamaha golf carts. All of these models are two-cycle, which should show our commitment to keeping these older carts going. Get Buggies Unlimited on the phone and book now for great deals.
