On the primary clutch on the sled that I just got it has a blue nut with a spring on it on the back side of the clicker bolt. Well I thought it was like the other clutch that I has prior to this one and I took the nut off to change clicker and I stripped the blue nut. I did not think that all I had to do was push up on the blue nut and the bolt would pop out and change the number and done, much easier. Well I called the Ski Doo dealership by me and the person I spoke to did not know what I was talking about with the blue nut on the back. Is this a Ski Doo thing? I just don't want to waste my time looking for something if this was something that the prior owner did. Thanks.
