Some people lock the flywheel with a large screwdriver. I use air tools on mine and it usually comes off no problem.

I use a decent impact gun, snap on, mac, matco. Im sure a craftsmen one would work also if it was a higher line gun.
When I removed mine my motor was on a stand and I locked the flywheel and also put a jackstand under the crank pulley. This kept the crank from turning and the motor from moving down when I put force on the nut. Also plan on having a pulley puller to remove pulley from crankshaft.
my standard 1/2" 90psi craftsman impact gun couldn't even touch the crank bolt after I had the engine out. You'll need something more substantial in terms of a gun to break it loose usually.
Since I was pulling the tranny and flywheel off anyway to replace the crank seal I just drilled two holes in a piece of steel plate, bolted it back to the crank where the flywheel mounts and used it as a lever when cranking the pulley bolt out with a 3/4" breaker bar and extension.

jagibbs: How many ft lbs of torque does that gun put out? I see a 90psi gun on craftsman's website that puts out 350ft lbs which should be more than enough.
^Trickster^, 93TurboDeuce: How much torque do the impact guns that you use put out?

I'm not sure but it's probably the one. I suspect that it does not put out as much torque in reverse than the max setting in drive (just from using it a whole lot I gathered this). It can barely loosen my strut pinch bolts torqued to 188 ft-lb.
EDIT: it looks like I have the 500 ft-lb gun. Sears item #00918852000 Mfr. model #18852. If I was going to buy another one, I'd spluge a little more and get something a little more heavy duty.

I just noticed that the maximum torque rating is always lower than the working torque rating, therefore my 500 is probably only good for about 250. Combine this with the fact that removing bolts that were once torqued to 250 for example, may require extra to break them free years later.

Ok... I had to work with wood unfortunately. I had doubts about it holding together but I ended up snapping the drill bits first. I then used some tight fit screws. Same story. I think I'm going to have to spend some money on a puller or rent an impact gun.

The first time i removed my gen 2 one was the most difficult, i hate to take the engine to my mates garage and use his impact drill and compressor as mine wouldnt undo it for the world, his big one is around 1000ft/lb and we had it on and off waiting for the compressor to charge for about 10 minutes!
