Hello people, I can do a little more research and probably find the answer but thought it would be easier to ask. I put a new belt on my 08 Nytro Fx and it has been squealing since. I have drove it roughly 20 kilometers since hoping it would stretch a little and stop but it hasn’t. I looked into a little bit and if I remember correctly, there are 3 screws in the backside of the secondary? That I can take out and either remove or add washers to, to open the secondary up a bit? Is this correct? I also had the secondary off to clean and grease the jack shaft and driveshaft bearings but I’m positive I put everything back the way it was. I also found that the primary sheaves were just a little warmer than they should be, I think, they were a little warmer than my ski Doo 500F anyways. Am I on the right track with the washers on the back of the secondary?
 

Yes you are. Need to open the secondary a bit for the new belt.
 
The tips of those bolts wear down.
Replace them or remove the washers.
