well since we have absolutely no snow, i'm down to double checking and cleaning things, and was reading up on clutches, and heard a few people talking about not polishing the sheeves on the clutches, are they talking about the whole thing or just the part that the belt rides on, so basically what i asking is what all is polishable on a clutch, and what isnt ?, and why?
thanks

What they mean is don't touch the inside part where the belt rides. Think about it...if that's slippery what is the belt going to grab onto?

A few years back on my dad's sleds there was some belt gunk built up on the clutches...like a thick, black coating of rubber. The belt wouldn't grip at this part because it was like gloss. He took some sand paper, started the sled up without a belt and rubbed all if it off that way. So if you're looking to clean it up maybe look at doing that if they're all covered in gunk.

Polishing the outsides is fine. Never polish the belt surface. Its actually great practice to rough it up a little one a year or before a race with a fine abrasive.

Only thing that it doesnt hurt to polish is the helix surface, makes it shift that much faster.

This is what tri-city polaris does to they're race sleds and all the sleds they do services on, Take 180grit sandpaper, start your motor without a belt, scuff it up lightly, and stop your motor, now make slight vertical scuffs up and down all the way around your clutch It helps a ton! and yes it is safe for your belt, but don't go any more coarse on your sandpaper

I wet-sanded mine with 220 grit....about 2.5hrs worth of sanding both clutches...that was about as fun as watching paint dry....really it should be done annually...
