Anyone have a flywheel removal tool in the Northern Jersey/NYC area I can borrow? Or maybe know where I can buy one?

Using your name as an example, all you need is a high frequency tone to ring through the flywheel. Tap it with a (metal) hammer on the outer edge and maybe wedge something behind it (not all the time though since a prybar will tend to lessen the ringing). The vibration will help disconnect the taper press joint of the flywheel and eccentric shaft. It's always worked for me. Oh, be sure to keep the 54mm nut on a couple turns if you like having toes.

Agreed; though I've always been a fan of lining the key to 12 o'clock and hitting the **** out of that back of the flywheel at 3 and 9.



Definately keep the nut on a little... I almost lost some toes the 1st time I did it. https://www.nopistons.com/forums/pub...1047683664.gif

Tapping the circumference of the flywheel with a hammer and using a crowbar around the edges to pry it up.

DO NOT PRY!



Just use a BFH

To remove the nut, I noramlly rent this puppy from teh local rental store, for about $30 a day after tax. (it breaks the nut in less than 10 seconds)

I then use a 2X4 against the flwheel, and then tap it with a 5 lbs hammer. Flywheel removal and installation in less than 10 minutes https://www.nopistons.com/forums/pub...IR#>/bigok.gif

I made my own puller from a short length of 1/4" X 2" steel. I just drilled it to match the holes near the center of the FW, bolted it down hard across the loosened FW nut and whacked it a few times with the metal side of a dead-blow hammer. Worked like a charm both times I used it.

Is this tool good to get it back on, too?
