Study the charts to insure you're selecting the correct belt size. Comet Series, center distance and driven pulley outer diameter. An incorrect belt size can cause excessive wear and possible damage to the belt, torque converter components, bearings... even your engine. Should your machine's center distance between the crankshaft and the jackshaft fall between the center distance settings listed here, select from the two belts, the one with the larger outside circumference (O.C.) for best wear and to avoid machine "creep" during idling.
