I am always looking at ways to extend the life of parts and pieces to save money, keeping in mind I hate breaking down because I was "too cheap". Belts are expensive and I hate throwing them away. Let's assume that the used belts are still in good condition, that there are no missing pieces, fraying, or overworn spots/dips on the sides.
Why couldn't belts be used until they start to cause performance loss (give or take a bit) and set aside. When a guy had several such belts, why could he not adjust the driven/secondary clutch to re-use those belts?
All my machines are Polaris. It is not too difficult to pull off the driven clutch and pull a shim, or add if necessary. It also does not look too difficult to reposition the motor to adjust belt tension.
How much belt wear (measured in thousandths?) can a 340, 440, or 500 size sled take without performance loss? What might be the problems encountered by removing shims from the secondary clutch? What does it take to reposition the motor for proper tension?
