Ok, I have the flywheel nut off, and no shops in my town rent or sell flywheel pullers that will work with a 12a flywheel.... Or so they say.

I've banged on it and banged on it with my deadblow mallet, and it hasn't budged a bit.

My solution is to make a puller, which I have already started work on. But, I have one question that may determine the fate of my endeavor beforehand...

The purpose of the Mazda special tool flywheel puller is to provide tension on the flywheel, away from the eccentric shaft, so that when it is vibrated loose by soft-faced mallet strikes, it wiggles itself outward instead of vibrating in place...

Do I understand this right? Or will my 3/8" flat steel bar with 3 bolts be a catastrophic failure?

The deadblow hammer is your problem. Try a 2-4 lb. hand sledge instead. Pry on one side of the flywheel with a heavy pry bar, then hit the opposite side of the flywheel on the backside, not the forward side. Don't forget to leave the nut threaded on a few turns so the fly doesn't fall off and crush toes.

As often as this question comes up, she could be a busy gal if she made house calls. No lewd comments please.

That part of the vid needs to be archived.

I've used everything from a 6 oz ball peen wrapped in several rags to the 4 lb rubber sledge hammer.

It just won't budge. Maybe I should let her take a swing at it. That demonstration makes me feel like a wuss.

Also, as I have the front cover, oil pump and chain, torrington bearing, thrust washer, etc off, the eccentric shaft has a lot of endplay, it moves a good 4 or 5 mm in either direction, which makes me a bit concerned every time I hit it with a hammer.

So, I'm going to go ahead and finish fabricating this "special" tool. If it works like I plan, I'll post the measurements and materials. If it fails, I'll groan in frustration and come up with something new.

get two prybars behind the flywheel, pulling it out from the engine, and then hit the eccentric shaft with a hammer, and it should come out. Worked for me.

I would never hit the eccentric shaft.

A 3/8" thick puller will bend like sheet metal trying to get that flywheel off. I bent the **** out of one thicker than that. I ended up making one out of 1.5"or 2" thick steel and it works great.

well, it's not really a hit as much as it's a tap. With a rubber mallet

Yea just hit it HARD with a sledge hammer a couple times.....it will pop off!

I used a 4' long prybar to get mine off.

This is how I modified a standard puller to fit the bolt spread on our flywheels. The aluminum angle is 2X2X1/4".

never had this problem. The pry bar behind one end while hitting the other side has always made all of ours pop off. Good luck

Probably cause you are... LOL! Never had a problem here. Try some PB blaster on the eshaft it'll slip right off after a few minutes.
