Possible to remove flywheel nut w/o special tools
Is there any way possible to remove a 54mm flywheel nut without getting the specialized tool or going to sears to get a 54mm socket(yes they have one my friends found it) The only reason I ask is because I dont feel like buying something im only going to need once. If theres no other way I guess ill just buy one. Anyone know what the nut is torqued to?

your going to need it more than once, i would just buy it it will make life a lot easier. the torque spec is something like 300ftlbs.
the other way to get it off its to use a chisel, and a big hammer.

Buy the tool. Always buy the tool. Something that big isn't something that'll just come off with a monkey wrench, and if you try and ruin the nut then your day is done.
I don't know the torque off the top of my head, but if I remember right it's big.
If money's an issue, buy it then sell it. I need one!

Definately going to need the socket. torque is over 500psf from the factory. I have only broken one out of six loose by hand. Good luck.
peace
forgot to add I had a 6ft breaker bar on the one that came loose

God almighty, 300ft/lb's I thought thats what I remembered it being I kinda figured I was going to need the tool. Whether I break it or not isnt a big issue since im not going to be using this engine. I just want the rotors and housings for display I think rotary preformance rents the tool out, I think I'll go give them a call.

i just pulled mine off. i went to sears to buy a 2 1/8 inch socket and used a impact wrench and it came right off. i didn't have to buy the flywheel holder tool either. i highly advise investing in an impact wrench. i bought one from harbor freight tool for $20. so their not to expensive and you can use if for every thing else on the engine

I read your email
Mazdatrix wants 36 for the wrench and 23 for the holder thingy. But they want $142 for the dowel pin puller! Ouch! What alternatives are there for that tool?

The 2-1/8 socket from Sears with a good impact works fine for removal. But torqueing it down is another matter.
Also, on mine I needed a big enough puller to get the flywheel off. I ended up buying one at NAPA for $20 or so.
Assuming you have a torque wrench that goes high enough, or can calculate the right torque with a standard torque wrench and extension, you will need somthing to prevent rotation while tightening.
Rather than spend the bucks on the holder "thingy" (which admittedly is nice), get a solid piece of steel bar stock about 2 foot or so long, drill a couple holes in it that mate up with the pressure plate holes in the flywheel, and bolt it on. It will prevent it from moving as you torque it down.
I haven't found a cheap substitute to pull out the pinion bearing and seal from inside the eccentric shaft. I ended up borrowing a tool from a mechanic friend.
Actually, now that I think about it, I did hear of a cheap way to remove the pilot bearing and seal, though I have never tried it!
Find a bolt or steel rod with a diameter as close as possible to the inside diameter of the pilot bearing. Fill the inside of the eccentric shaft with a heavy grease. Insert the bolt or rod, and hit it HARD with a hammer. The force will compress the grease, pushing the pilot bearing and seal out.
Like I said, I've never tried it, but worth a try.

Puller BLAH I broke 2 of them on my 12A once, pullers suck. all you need is a framing hammer, or a small box hammer.
Turn the flywheel 1/8 turn, hit it from the back side, turn 1/8 turn, hit it again, turn it , keep repeating till it comes off... Remember to leave the flywheel nut threaded a few turns so you dont break your foot, or loose some teeth on the flywheel from it bangin' the floor.
I got a 3/4 inch drive snap on impact gun, I have seen it countersink lug nuts set on power 3 setting. It goes to 5... Thats like 450 lb

Cheap puller suck.
If you need a good puller get an OTC.
You will not break it.
They have a lifetime guaranty if you do.
The only exception is using an air tool on the screw.

Airflow is my life
Its called a BOLT! Thread a lug bolt into the dowel pin and pull it out with the rear hatch holder/ I mean vise grips! Man you guys need to do pushups or something.
