Arctic Cat '07 650 H1 Belt Slipping?

[ath1981]

I have an '07 650 H1. Recently, when trying to take off easy, it acts like the belt is slipping. If I give it the gas, it grabs and takes off. It has 1300 miles on it and it has never had water or mud in the belt housing.

I can think of no real reason why the belt should be worn enough to slip. Could there be some kind of lubrication problem not allowing the sheaves to move properly?

One idea is that if you stop suddenly the ctv does not have a chance to close properly wedging the belt and holding the sheaves open. When you attempt to pull away the belt slips (and chirps) into the lower position allowing you to have the proper gearing.

Secondly belt dust can be a problem even without mud or water in the cvt. take the footboard off and then the clutch cover. The two long bolts go towards the back. Make sure not to tear the metal gasket it is reusable. Then clean everything with brake cleaner if needed. Also check to see if the bolt on the primary is tight (if you never took the primary off then you wouldn't have to worry about this)

Finally I would be suprised if the belt was out of tolerance at those miles and you should be fine with a good cleaning. After you clean things up let us know if it is still happening and what kind of noise it is making ie chirp at start or constant squeel or noting.

Something similar happened to me this winter when I was plowing. I tried to push a large snow pile and glazed the belt by having it slip when attempting to move forward. I changed the belt with an older spare and all was fine. I was also told that you can attempt to remove the glazing with some fine sandpaper by sanding the sides of the belt lightly.
