CLUTCH PULLER BROKE TRYING TO PULL PRIMARY, now what
- Thread starter yosh30

The simple answer is yes.
I would heat the center section of the clutch (the part the puller is in the middle of). Hopefully the heat will cause enough expansion to pop it off if the puller was tight when it broke. I am going to guess it was. The next step if it doesn't pop with heat, would be to heat it again and with a large rubber mallet hit the end of the drive clutch. The impact will cause the spring to compress and when the spring snaps back it will sometimes have enough of a slide-hammer effect that it will pop the clutch off the crankshaft.

puller problems
Ok I had a problem like this last year. It was an 07 m8. The clutch would not pull of and I have pulled of many many clutches. I bent my first puller. Bought another, it started bending so I stopped. I then brought it to the dealer, granted it was a Polaris dealer but they also couldn't get it off. They put heat to it and then still ended up bending there puller. The only way I could get it off was by using my mostly straight puller and putting Teflon tape on the threads that grab when your pulling. Then tilt the sled on it side or motor what ever, and fill the bolt hole with water and put the puller in and make sure you get a good seal with your threads. Then tighten it up to the point of it almost bending the puller again. Now it must be cold out because you have to let it sit outside overnight. I needed to try this three times before it finally worked on a night when it got down to about 10 degrees, but the next morning it was loose and I was happy.
Hydraulics, when water freezes it expands and pushes the clutch off.

What exactly are you dealing with. Is the bolt stuck in the clutch and broke off flush with the surface, threads stripped, or tip broke and you have the main part of the bolt out?

Last resort is get a razor wheel and cut the clutch off. Had to do this with a 900 clutch one time. The spider was broken anyway so I wasn't to worried about it but that was the only way it was coming off.

the bolt is out, the clutch puller is the thing that is broken in the clutch..it broke at the threads so its about 2-3 inches inside of the clutch..
so far tonight ive applied heat for about an hour (with heat gun) and hit on it with a rubber mallet......and nothing
i put water down the hole when the sled was on its side, i put two wraps of teflon tape on the bolt and started tightening until...SNAP...puller broke, no bend just snapped
i just put heat back on it about 10 min ago so ill wait til later tonight to hit on it

You gotta get some HEAT on it. A heat gun is for putting decals on. Get a propane torch are a real torch. You are just pissing it off with a heat gun.
The clutch fairy came to see you.

Glad it came for you. Just putting this out their for others. He was lucky the heat gun worked, usually they don't get it hot enough. when you heat something like this apply the heat as fast as you can and then once it pops cool the crank off with cold wet clothes so the heat does not seep into the seal. Rosebud tip on the old cutting torch works best. Soldering torches work best with mapp gas.

I guess I have never heard of water in the hole and teflon on the threads, but I have always used a couple squirts of grease which would work on the same principle I suppose. I have had some tough clutches, but with the greasethey have all come loose, and I have never had a bent or broken puller. Glad your clutch decided to let go.
I've always just tightened up the puller. Then hit the puller with a sledge hammer a few times. then tighten some more and repeat. I've never had an issue, even with primary's that haven't been removed for 10 years.
Another tip for those in the future:
I don't even use a puller to take the primary off.... Tip the sled on it's side and thead in a bolt with some sort of fluid in the end of it. I've had good luck filling it with water and then stuffing as much soggy paper towel down the hole as possible which keeps the water from coming through the threads when it's under pressure.
Liquids are incompressible so if you can get a good seal on the threads, it doesn't take much force to get any clutch off. No heat, no pounding on your crank, no reefing on a huge breaker bar...

I think that puller is probably bad... you should consider getting a new one...
well i guess the heat gun did the job, came back from getting some propane and the clutch was sitting about 5 feet from my sled..thanks for the help guys..
the mystery here is....did the clutch move 5 feet from the sled....or did the sled move 5 feet from the clutch...
