how do you get it off? not use to that style secondary. do all 3 bolts come off?

nobody knows not used to this method of loosening belt deflection. always had the key method secondary to adjust deflection.

To adjust deflecton loosen the 3 bolts and turn the cam on there. There are numbers on the secondary that the notch in the ring line up with. Turn cam counter-clockwise to reduce distance between sheaves.

You need to remove one of the three bolts and install the bolt in the tool kit. This will open the sheeves enough to remove the belt. With the PERC you cannot open te sheeves like a normal Polaris sled.
