2018 Mountain Cat M8000 Clutch Help

[CatRunnerM7]

So doing some maintenance on my sled I found a crack in the face of the primary and tapped it and an entire chunk of the clutch fell off. Everything else on the looks to be in good condition. And I was running it the day before. So it works. Any ideas on how to fix this without buying an entire new clutch??

Or is there a shop I can only buy this face plate from?

You could just buy the 911 clutch cover but check the sheaves too mine were cracked at 1600 kms so I just bought a whole new clutch.

My sled has 1650 miles on it and clutch seems to be fine. Where would you reccomend I get the cover from?

You could get a 911 cover from Thunder Products, ZRP, Bikeman, or Indy Specialty and have it rebalanced. However, given the history of the movable sheaves coming apart on these I wouldn't chance it. If the cover has cracked the towers have probably flexed. Making it more likely they will crack too.

Agreed not worth the risk just go a new clutch and you should be able to get the new updated primary clutch now so maybe its better.

could put a ZRP cover on and run it unbalanced for a ride or two if you had to but I would first pull the spring and hold the cover up and push the sheave all way in and see if it bottoms out on the cover before the sheaves touch. if so you will have problems again down the road. Id shop for a 20+ clutch replacement in that case.

I took my calipers out and everything from the original clutch was basically the same as my buddy's clutch. I'm assuming there is no stretch(or at least very limited). pushing the sheaves all the way in gives me a little tighter measurement than his sled as well. So I think all is well there for now. Would I have to rebalance my clutch? Just asking because I have a weeklong sledding trip coming up and won't have time to ship it out. I also don't know of a shop around me that will balance these. My thought was that I could send it to Indy specialties after I get back. Is that too much to risk or what are your thoughts?

 

[boondocker97]

All the dimples drilled in the cover are from the balancing. Changing the cover puts you back to being unbalanced. I know ZRP requires proof of rebalancing to warranty their covers.

That being said I have changed a spider on my M7 clutch, and also adjusted belt to sheave clearance on a m1000 clutch which changed the indexing. Ran both without rebalancing. Just depends on your confidence level and accepting issues caused if it's way out of balance.

 

[CatRunnerM7]

Okay. I'll see if I can get a local machine shop to try and do some sort of balancing to it. Some is better than none right?

clutches should be balanced anytime a large piece is replaced. not saying it will cause you issues but it 100% can. that being said i did replace my cover with a ZRP cover with no issues. id be a bit more leery with yours as its already had "failure"
