Mine had the original setup, which consisted of the bolt with one thick washer and one "slippery" washer. No update had been done yet. A week ago the outer primary slipped, got the belt hot, and the belt exploded. Yesterday, the primary slipped again, but this time it tightened up the bolt until it stretched and broke. If you do some research on Google or the commander forum, you'll find this has been a problem for the last three years with the commanders. I joined the commander forum in September after learning of the Maverick to check out the reliability. I found that the steering rack, the primary CVT, and the rear differential were the three main problems. Steering racks will ALWAYS be a problem in any kind of off-road vehicle. They put a larger differential with helical cut gears instead of straight cut gears, that solves the rear differential problem. The only thing they've done to the primary is more slippery washers, which I'm thinking will just add to the problem. From what I read on the commander forums, and what a few people with past Can Am experience here have said, is that the solution is to put a CVTech///AIRDAM, or QSC primary on the Maverick. Either one is about $820.
