Hello. I was riding around doing some more break in today and I noticed this nails on a chalk board sound. At first it sounded like it was coming from the rear roll cage on the cup holder side of the Ace. Upon closer listening it became apparent that is was coming from one of the clutches. Pulled the clutch cover off played with the primary clutch a little and found that the noise was coming from it. Removed the primary clutch and found that all of the bolts holding the inner clutch cover in place were all loose (never thread locked from the factory). One of the bolts had backed out enough from vibration that it put gouge marks in the back of the primary. Good thing I caught it before anything worse happened. Thread locked and reinstalled the bolts put the primary, belt, and outer clutch cover back on problem solved. I could have taken it to the dealer but since my hubby and I used to work for a Polaris dealer for years we like to tinker with our own toys. I am posting pictures so you can see exactly what happened. View attachment 860 View attachment 861

That is really interesting, because last time I took the ACE out, I heard noises that could be described that way.
I figured it was belt squeal, which I've never had with the RZR, but I guess is pretty common with the Sportsman line.

So now I'm going to take that pulley off and have a look.
Thanks for posting this!

Thanks. Always happy to help. I know that some people don't know what noises are normal and I figure if we all pool together we can save each other from possible bigger problems by fine tuning these types of things before they go too far!

Took my clutch apart yesterday. No scoring on the pulley, and the bolts seemed to be seated.
I did wrench on them a little, and they moved without much effort, but it wasn't a "break loose and spin free" thing.
It seems like they have something on them to resist movement from vibration. There does appear to be some sort of gooey substance on them.

Anyway, I put it back together as is, and I'll just keep this in mind if I hear anything weird back there.
The noises I was hearing were probably normal belt squeaks.

But I don't consider it a wasted effort! I've been meaning to get in there and swap out my brand new spare belt for the "proven" one that has been in there for the first 90 miles.
So now I have a brand new belt on the clutch, and a slightly worn one that I know is good in the trunk box.

Awesome glad to hear yours checked out ok Scoundrel. I have been joking with my dealer saying mine was built on a Friday by a pissed off ready for the weekend employee hehehe. It's better to be safe then sorry. Once season gets up in my neck of the woods hopefully in a couple of weeks I will be piling on the miles. I would rather find things like this if they have to happen during break in at home riding than on the trails miles and miles away from the truck and trailer.

Yep, that's why I checked it out in the garage instead of waiting to hear if it changed...
