    Happened to mine also. Dealer said Polaris suggests the belt to have a certain tension after replacement swing arm. But when they compared to models on the floor Polaris sends the units with the belts tighter. Take back and have then tighten belt.

    Mine was really loud but since the recalls were performed at purchase time I didn't know better.

    It wasn't until Henry rode it and told me it was really loud that I looked into it, turns out the belt was way too tight and installed backwards.

    Now my machine is super quiet.

    There's a backwards to it? Can someone explain how you'd check?

    Gates says the belts are uni-directional but once installed and used should not be reversed.

    The belt is TOO TIGHT. The carbon based belt that Polaris uses Shrinks when it gets hot. When this happens, it pulls hard on the pulley bearings and also makes a lot of noise. If left this way, you will end up having to replace the rear pulley bearing before you know it and there may be problems with the L-Drive pulley bearing as well.

    The polaris service manual shows a rediculously tight tension adjustment when cold. Then after driven some, the belt gets hot, shrinks and the belt is now so tight that there isn't any flex. Many dealers adjust the belt according to the service manual just like mine did. As soon as I got it home, I loosened it up and the noises went away.

    As per Polaris recommendation while standing on the passenger side and looking at the belt you should be able to read the numbers on it.

    Mine was misaligned and too tight, since it was installed " backwards" they fixed at the dealer's expense which they were not happy but Polaris forced them since it was their mistake.
    Also it is now on record that it was set too tight something like double the rate and wrong by the tech in case that there are any other problems in the future that might be caused by the over tension.

    Mine was the first recall they performed and it was on December 30th( Friday) because I was picking it up next day in the morning( sat Dec 31st).

    Wow, I will check the numbers on the belt in the A.M. It makes sense that the belt should be reinstalled in the same direction as originally driven with. I blew one belt out months ago and took pics but it was almost as if a rock had gotten stuck in the sprocket.

    getting my swing arm replaced this week coming up. Is there a specific speed that you noticed your belt making noise? Want to test mine out before I leave the dealership.
