Re: B1 Cylinder Head
They sell stuff for loosening threaded bolts and holes & nuts. Liquid Wrench, etc. If all else fails, you can use a nut splitter, after that get a new nut and clean up the crank threads. The flywheel is on a taper, so its not going to pop off, most have 2 threaded holes and you run 2 bolt thru to the cases and force it off. You can remove the clutch housing and put a socket or..... to hold the crank from turning when you try to take the nut off. I have an air gun and Kawasaki electric wheel nut remover, I keep in my truck/SUV. Make sure its on off and hit it, always works for me.
