Stripped threads in primary clutch :(

[yz400ex]

I went to help someone pull a clutch on their sled today. He had bought a Polaris primary clutch from some guy awhile back and put it on his Arctic Cat.. Has been working great, but on Saturday while riding the spider nut came loose.. Can probably tighten it with it in the sled, but would be much easier to remove it to do so.. Went to thread the puller in and it never gets tight. Feels like it is going to get tight, then just slips to free.. removed the puller and you can literally push the puller in past the threads w/out even turning it.. What now? Re-tap and rig up a puller? Any experience this? Any suggestions?

I did the same thing. My clutch didn't give that hideous "POP" that we normally hear with a Polaris clutch, so I didn't know it was free. Anyway, I had to find a tap to re-thread it. I was nervous as could be. A friend suggested that I could also put some anti-seize on the bolt and impact it in. I went the tap route first and it worked well. It is metric and I can lookup the exact size and pitch (the pitch is very important) if you need me to. This is for a Polaris crank, so the AC might be different.

well if the puller can still get a small grip on the threads i would....
-tilt the sled on its side
-wrap the threads on the puller about 10 times with teflon tape
-pour water in the clutch bolt hole
-then slowly ease the puller into the hole trapping the water and threading the puller in
-now tighten up the puller and hopefully the hydraulic pressure should pop the clutch off if it has enough grip

good luck

I don't think he can get the puller threads to start.

We tried lots of teflon.. Its a no go on that.. It does not get tight enough for anything to work. The puller will thread in like normal with the teflon, but w/out you can push right past all the threads. Its like the puller is just too small, but I know it isnt unless this clutch has been tapped before. We used the same puller on another clutch and it worked fine.

crap, well im out of ideas

If you can get the puller in with the tape but not enough to get it to pop and the tape holds back the water could you get it in there and give it a blow with a hammer, intern creating the hydralic pressure? Just a thought, shouldn't wreck the threads anymore as the puller will slide right through already.

Skibreeze popped off a clutch with just a tree and a Harmon high lift jack.......Maybe just be a little more innovative

what about the same idea as the water and teflon tape method, only instead of trying to get the puller to do the work you use lots of teflon tape and let the sled sit outside over night until the water freezes and hopefully pops it off

If it wont hold pressure with the threads it will just pop out the puller when the water expands.

yep..heavy wheel brg grease works as well if doing it this way...if the hitting force/rate is greater then the escaping rate of the water or grease she will hydraulic like you say..

When you do the water method on a Doo, you use the clutch bolt and wrap it with lots and lots of teflon tape. Not the puller bolt.
