Hey is there some secret to removing the flywheel on this bad boy? I've got the 3 bolt remover and I've been turning at it all day(see pic). The bolts are even, and I'm a reasonably strong guy(in my mind anyway :D), shouldn't this thing give at some point? I read the removal thread but I guess I'm at a loss still because it's awfully stubborn.

Aw c'mon, don't be a wimp. You are a strong man, tighten that sucker down. If it still won't come, pry the flywheel upward LIGHTLY, just enough to raise it in the bearings, and give the puller center bolt a light rap with a hammer. Don't bash it with a sledge. It is the shock that does the trick, not the bash.

That little motor is one of the easy ones. It will come off.

EDIT: I hope you are using Grade-8 bolts. And screw them in the flywheel 7/16", no more and no less. Anything lesser may break and make you say durn.

Agree with the "shock" thing. Not too much though. That and time and it will pop.

K I'll have to eat some wheaties tomorrow morning and muscle up. I can see I have some work to do in there from the peak hole the coils are cracked at the very least.

Try tapping the center bolt with a brass hammer or gently with a ball peen hammer as you tighten the center bolt. Go a half turn, whack it, then another half turn etc.

Ditto X 10 on the tapping of the center bolt. I never use a puller without a hammer. On a flywheel removal I'd say use the force equal to what you'd use to drive in a finish nail. Don't flail it, but don't baby it either. I have caused damage to stuff by just winding down on a puller, but I have yet to screw something up by tapping on the puller bolt.

Airgun would have that off in 5 seconds, if no airgun, then MC hammer it like they said.

Read FR's post above about prying up LIGHTLY on the flywheel and then tapping on your puller bolt. Prying up saves c/s bearings. Put your pry bar on top of the cyl between the flywheel and the mag plate and apply pressure.It also may help by rotating flywheel 180 degrees when doing this.
