Is there a problem using a big screwdriver, the flywheel nut and a brass hammer?
Remove the nut till the top of the nut is even with the top of the threads on the crank, lightly pry the flywheel from a prominent location off the block, whack with the brass hammer on the top of the crank/flywheel nut. First time you do it and it releases you might piss on yourself.
Sorry if this is a redneck solution, but it's all I got.
