I bought a Carlisle belt for my Polaris 600 Fusion. When I put it on the sled, it squealed and turned the track when the sled was on the track stand. I was told that I need to adjust the secondary to make it sit. Is this an easy adjustment to do? I also had a new Polaris belt and it runs just fine with that in there. Wondering if I should just return the Carlisle belt or if this is an easy, common adjustment to have to make. Thanks.
