Flywheel removal
I am trying to remove my flywheel from my 2000/2001 Sportsman 500. I have the harmonic balancer puller, but it seems no matter how hard I crank down on it, the flywheel will not move. I am even using a pneumatic ratchet and airgun. I have also tried a 4 foot cheater bar.
I have removed the center nut and washer. Is there anything else that needs to be removed. I have pushed it to the point where it feels like something is about to break.

not good... i had a sled do that to me before.. hour after hour....i known this way is wrong but hey....wtf it worked for me...i put the puller on and snugged it up then i got out the torches... heated up the balancer around the crank and then with a mallet i started to tap the center nut on the puller tightened more keep it up for a bit but it did pop off...remind you that was my last resort and i was rebuilding the motor

Well, no luck so far with this. I have tried the penetrating oil, I did filp it up on it's side. I then used some putty to build a little cup around the bolt and let it soak for two days in the oil. I tried heating up the flywheel and tapping it with a hammer. I do not know what else to do to get this thing off. It stubbornly refuses to budge. I am about to just put it all back together and sell the thing for whatever I can get. I am getting a new one soon anyway. I juts hate to dump it off on someone knowing there is a problem with it.

Ok, I just spent about an hour trying to get it out, still nothing. Won't even budge, but I did break the puller. I heated it up till stuff was smoking pretty good behind it, then sprayed penetrating oil all over it. I let it sit for about 30 minutes with frequent applications of more penetrating oil, then I heated it up again and cranked down good with the puller. I hammered it good with the 4 Lb sledge until I was afraid I would bust something in the crank case that would be expensive and difficult to fix, then I put my 4 foot cheater bar over the breaker bar and had a buddy hold the puller stationary while I cranked it. One of the 3 bolts holding it to the flywheel broke so I replaced it. I then tried again and the center bolt, the big black one I have been tapping on, crumbled at the head.
I am going to return it tomorrow as it has a 30 day warranty. Any other suggestions? I am thinking of some type of slide hammer puller maybe. Maybe something like this.

Well, no go so far with the slide hammer either. I had to rig up a special jig to get it on there, as the axle puller that came with it was to big. I think my next step is going to be to hook it up to the trailer ball on my truck and give it a good yank. Any better ideas before I go this route?
