My grenaded belt...WARNING graphic belt pics inside

I have a 2011 RZR 4 Robbie Gordon ESP. Two days ago I was cooking down the road at 60mph when I heard a pretty big clunk followed by a bunch of shrapnel bouncing around in my clutch cover.

So I grabbed my car hauler and brought it to my garage (which is much closer to my beer fridge than the side of the road). When I pulled it all apart I found a messy scene, so I figured I'd take some photos and share with all.

In the end it's back together except I'm now waiting on a new clutch cover since the event blew a hole in it. Oh well, that's the way it goes sometimes.

One thing I found strange, the belt seems to have delaminated where the upper and lower teeth are bonded together. Has anyone seen this before? My dealer said to bring it in and they would check it out as a warranty issue. But they are 45 miles away and I'd have to bring the RZR (not just the belt pieces).







As good as new (except the cover).

Re: My grenaded belt...WARNING graphic belt pics inside

I learned the hard way... Once that happens, clean out all the stuff you see. Getting that cord off the primary makes you think you're going to pull start the engine. Once you think you have it cleaned out, start the engine and rev it a few times, not to the rev limiter, but enough to make the sheave open and close a few times. I was amazed how much crap came flinging out from within the assembly. If you don't get all the junk out, your clutch wont work right. Then I took a coat hanger and got the rest of the crap outta the cooling ducts attached the the cover. My exhaust vent looked like it had a rat's nest inside of it! Then I took a green kitchen scrub pad, and scrubbed all the melted rubber off the aluminum, and cleaned that pad residue off too. Then I washed the new belt in hot, soapy water to get the release agent off the belt from the manufacturing process that could promote slipping. Once all that was done, I installed the new belt.

It seems like someone posted something about there being a bulletin about the pulleys not being lined up, and causing wear on some machines.

Are you running stock tires? If they're aftermarket, you might need to reclutch to your tires. My paddles killed my first 2 belts.

It took out my cover. My situation was exactly the same as yours. Flying down the trail at 60 mph when she let go. Sounded like the tranny fell out and was dragging on the road behind me....lol

Re: My grenaded belt...WARNING graphic belt pics inside

I was talking to Dale at Dalton Industries the other day about their new XP 900 kit and we got off on the RZR 4 and he said ALL and I mean ALL RZR 4 need a clutch change. He said Polaris is way off on the RZR 4 and that their kit really helped the RZR 4 and cut down on belts blowing.

Belts blow typically from heat. What is causing the heat? CVT filters. snorkels, weight of vehicle and bad clutching.

Give me a call if you would like to discuss it.
