Well after a 6 year break from sledding, I've decided to get back into it with an '11 pro rmk 800. I've read everything i could on the secondary offset, which as I can tell is way off alignment towards the bulkhead. I know I should get the proper alignment tool, but have another concern, when the secondary bolt is removed, and primary is rotated, it will float the secondary to a somewhat centered, relaxed, and aligned position. The concern is, is that that position is nearly 1/2 inch away from where it rides with the bolt in. In that relaxed position the stock bolt won't even grab a thread. When everything is bolted up ready to ride, I can place a straightedge along the outside of the secondary fixed sheave, and it will contact the belt before it even gets to the primary. Is there anything else that could be affecting the offset so badly? Engine mounts are good, and the two clutches are parallel. I don't suppose any inner bushing could have slipped on the secondary causing this offset?
