Well I put a new belt on my Dads 03 650 Prairie and Now the things squeals and it hard to shift in and out of gear. Yes I put it on the correct way and all. Whats the deal?

 

If it's squealing in gear it has to be too tight.Did you make sure the deflection was no less than 22mm?When I went to a 700 belt and set the deflection at 22 mine squealed ever so slightly at idle in gear but has since stopped.

How do you set the deflection when installing a new belt? I've heard that it's a difficult procedure.

Thanks

 

You remove a shim (washer) to make the belt tighter, or add a shim to make the belt looser. There should be a few shims on the fixed sheave's shaft of the driven converter. You should remove/add one at a time and check/measure.
