No cracks, yet anyways. LOL, I'm the exact same. I'll tear it down to the frame in the fall and have a fun time doing it. In the winter, I don't like taking the side panels off to blow out the clutches. If it happens, it is a nasty surprise. Haven't seen it happen on a trail sled.

Are there any differences between the engine life on a R XC and RR? I haven't checked part numbers but even if they are the same the mapping could be different. Do the XC guys do a race flash that doesn't ship from the factory? Quote Link to comment Share on other sites More sharing options...

An ice sled, I'll typically put pistons and rings in it at 750 miles or so. Terrain at 1500 miles. Mapping is different, but I'm not sure how different. Some of us will get different flashes throughout the year. Some Polaris racers will have a different flash every weekend, if not a different one every day. 1 Quote Link to comment Share on other sites More sharing options...
Tomas. Posted November 18, 2020 Share Posted November 18, 2020 So I have a primary clutch from a 2008 polaris rmk 700. It is a buddy's sled. I was checking it over and servicing it. One of the weight bushings was absolutely cooked and the roller for said bushing also has a little problem. It would appear that the roller disintegrated one one of its bushings and the roller wore into the spider. Should he be looking for a used clutch or can a bushing be put in and it will be ok? If he needs another clutch, can he get one with a starter gear and just take it off as his is pull start? Does anyone know what years and engine sizes he can get one off of?

teamgreen02 Posted November 18, 2020 Share Posted November 18, 2020 There is definitely wear on the roller but is it bad enough to rebuild or replace the clutch is another story. Someone like Ben who is an expert in clutch will be along shortly I'm sure. This is a Team primary that I junked. Probably not going to leave me stranded in that condition right away but not long for the world either. Quote Link to comment Share on other sites More sharing options...

They were getting replaced anyways as they need to be 6grams heavier. Was planning on replacing the pins while in there. But that particular weight had a ton of slop. Way more than the other two. Like almost 3/16" side to side. Quote Link to comment Share on other sites More sharing options...

Because the roller took away some material and I am not sure if I just put in new bushings, it just won't break the new bushing. Quote Link to comment Share on other sites More sharing options...

If the weights are junk, rollers need a rebuild, and you are worried about the spider then you might as well just replace it. Maybe find a used one if it isn't a sled that gets used much. The parts to rebuild the clutch are a couple hundred and then another couple hundred for all the tools required. Might as well just buy a new clutch for that. My old one will stay in the truck as a spare. Quote Link to comment Share on other sites More sharing options...

Or will he need to find a clutch that is a non e-start only? Quote Link to comment Share on other sites More sharing options...

You should be able to take the e-start ring gear off and replace with the one you already have. Or just run it with the e-start ring gear, probably won't hurt anything.

Tomas. Posted November 19, 2020 Share Posted November 19, 2020 I suppose the only downside to having the ring gear without e-start is the added weight without a purpose. I think a brand new clutch is around $700 cad. He isn't looking to spend that kind of money on a sled that will hardly see any miles lol.
