The bushing in the back of the crank is only on LX engines (Charger, Magnum etc.) Use a carbide cutter in your die grinder to cut a groove through it, ( relieves the press in tension ) had it out in 10 minutes...
Nice to know what engines come with that. I cut a bunch of grooves in mine, but it was just really stubborn. Finally managed to cut enough of a slot in it to get a pilot bearing puller on it and get it to move, then it pulled out okay. I still have it sitting around, I should take a picture of all the trouble, lol.
