i use a 18" breaker bar. block the flywheel with something, then put the breaker bar on it level with the ground. then either use a friend to hold the motor still and a 5' cheater pipe, or use a 3' section of 2x4 or sledgehammer and hit the breaker bar with that.

You just need the right tools. If you've got the tools, you can have it off in several minutes... If you don't have the tools, you're basically screwed. 
My method uses a "custom" steel *tooth* setup, that locks into the flywheel and prevents it from spinning. After this, the engine short-block is chained to a peice of 2x6 or 2x8 lumber, which prevents the engine from 'rolling over' as pressure is applied to the breaker-bar... I just use my 1/2" breaker-bar with a peice of heavy steel pipe for the extra leverage. After several moments of 'pumping' pressure with the (42mm?) socket and breaker-bar, with the locked flywheel, the nut comes off.

Just to Pop in and say that the Flywheel Nut is 2-1/8 or 54 mm . Heat is good(torch) on this application.Just make sure that Once it comes off,You don't Bend over and Pick up the Nut..OUCH!..oh..if you don't Have a socket that Size YET..you could always throw the KEG in the back of a Truck/van (whatever) ,then take it to a Truck stop Tire Repair center(or somewhere similar)..they would have the 1" impact Guns that would make this Job Look So easy.When you put the Flywheel back on,you can either Have the Socket or make another trip...anyhow..something for ya.

Im with mytsterstyx here on the tire change shop.
A 3/4" or 1" impact will zing that little bastard right off. I've even had sucess with heat and 1/2" impacts in the past.
Once the nuts off, thread it on a couple of turns and proceed to smack the **** out the flywheel Continue smacking the **** out of it until it pops off....and done.
Just a bit of good ol' elbow grease on this baby.

It's easy if you work out a little:

Seriously though, check the FAQ. There are several links to topics that extensively cover flywheel removal.

I have the Mazdatrix flywheel wrench and breaker bar purchased about 10 years ago for $50. I think I have my money's worth out of it. I don't know too many people with impact wrenches in their home garage that can handle that kind of torque.
After the nut is off, I put a gear puller on the flywheel amd tighten up and tap on the flywheel with a hammer to pop it loose. Usually if a flywheel has been off already once in its life I don't even need the hammer.
