I bought a couple of new Polaris belts and installed one of these belts and I am having a problem with the belt grab. My model has the one way bearing between the clutch sheaves. When I engage the throttle the belt climbs up the sheaves normally, but when I let of on the gas the belt does not return to the center bearing properly. I seem to jam outside of the groves and push into the engine side clutch sheave causing the belt to be engaged at all times. This makes it impossible to shift out of gear without shutting down the engine. It's almost like the belt is too narrow, it just will not return to the groves of the center one way bearing. Do you have any insight as to what may be causing this?

Thanks for you time,

Welcome!
I belive most Polaris driven clutches have the 3 screws to adjust the belt tension.
It is just set for the old belt and needs to be loosened for the new belt.
You will want to tighten it back once this belt wears in.

Not all Polaris sleds have those 3 screws, the older styles did not.

What exact model and year is it? That will help out a lot.
