Subject [FlyRotary] eccentric shaft pulley bolt removal

Fellows,

Been trying to tear down an extra= FD engine and I=E2=80=99m having a devil of a time getting the front pulley = eccentric bolt off. The flywheel nut has already been removed. I did put t= he counterweight and flywheel nut back on to be able to bolt a bar to the c= ounterweight to keep the eccentric shaft from turning when trying to get th= e eccentric bolt off. Here is what I have tried so far: breaker bar extensi= on pipe (+3=E2=80=99); propane torch on bolt for 2 min to break any sealant = (?); impact wrench-nada; sledge hammer on breaker bar; solvent.

Nothing worked. The engine just lifts off the floor with more= torque. Does it take a gorilla to get this nut off???

Any ideas how to get this dam bolt off?
