My drive clutch is shot on polaris indy 500 1997 looks like someone tried to build up the shaft and machine it at one time. 4000 miles on machine. Ther is a small crack on the outer body part where the belt rides (the moving side.) butons are worn, weights are good. Bushings (both) are worn. Shouls I try to salvage and rebuild this clutch or get a whole new one ??$$$$. anyone know a less expensive alternative? My shop says a Artic Cat one will fit right on. Is it worth saving some bucks on a Cat one or a Comet? Would all this Loose/Worn clutch contribute to a hard heavy engagement (@4500rpm) and not letting it rev up until I get rolling? Or could this just be the spring?? (Gold) What would happen if I cleaned it up, new buttons, new rollers, new bushings, and put a blue spring in? also if this small crack gets worse could it cause serious damage other than wrecking belt.
