new belt slipping Polaris Sportsman 2011

[technofarmer]

  Hey there, i have recently put a new drive belt on my 11 Polaris Sportsman 500 H.O.    It has 44 miles since putting the new belt on and should be nearly broken in as i hear it takes 50 miles to do so?  Anyhow it has had a little trouble with slipping since i put the new one on a few months ago. Now whenver i go down a hill the belt seems to be getting caught in one clutch if not both and then it has to run a high rpm just to go a low speed.  Today it did that again going down hill, i stopped, put it in neutral and when going back up the hill i had to turn it off, put it in neutral, let it roll back down the hill a little, then restart it, low range and it was slipping but thankfully i was able to make it up the hill. 

 

 So what might the problem be? Is this a need for another new belt? New clutches and belt? Or just get something else? BTW the brand new belt i put on it, is a factory one, an exact replacement for the original.

Hi there. I've not had any hands on experience with those things, but my son has a canam and I've looked in the manuals a bit. And I have had my hands on a Jacobson hauler which is similar.

I'd suspect that one of the clutches is getting sticky on the bushes in the center of the clutch hubs.. Which looks to be a pretty simple thing to look into. I'd whip the belt off again and see if the moving parts slide on their shafts.

Yep, sounds like a clutch issue instead of a belt issue. May have something worn, broke sticking etc and not allowing it to contact the belt properly.
