Seized Motor, Rear Cast Iron won't come off
So, I can't turn the e-shaft at all. The front rotor housing came off along with the front cast iron. I've only been able to move the rear iron 1/4" from the rear rotor housing. I've hit at it with a rubber mallot for probably 1 hour or so and all I got was that 1/4 inch.
Has anyone experienced this before? How do you get that iron off?

Most likely a spun rear main bearing locked onto the eshaft. you have to continue to beat it, and you will sacrifice the iron in doing so most likely. if you have a 2 or 3 jaw gear puller I suggest you use it to remove the stat gear or perhaps the whole iron. there is the distinct possibility that, with the rotor bouncing around with each hit, it will sustain damage as well (if it hasnt already).

you can't dismantle an engine where the eshaft is stuck to either end iron or either rotor as a result of a bearing failure. because of the eshaft's bend around the INT iron. For instance, in this case if the rear iron and eshaft are locked, that means there is no way to get the INT iron, rear rotor, and rear rotor housing off without the iron coming off. You can get the other half apart, though.
wow, that sucks. Just keep trying, maybe try to get some sort of lubricant, or pb blaster(crap for stuck bolts) in that area... that really sucks, I wish you the best of luck!! You'll get it!

Lubricant usually wont help at all. The bearing has spun and usually welded itself to the eshaft. The way I usually get them apart is to just bang on the end of the shaft, perhaps it'd be a good idea to thread a spare flywheel nut on the end to give yourself a larger target. This should drive the shaft and (bad) bearing out of the stat gear and rear iron. Then you can use a cutoff wheel to slice the bearing off of the shaft, and slide the rotor off. OR, like I said above, you can use a big gear puller to push the shaft out of the stat gear/iron too. Those are pretty much your only options.
