I wrecked a 1/2hp DC motor heating the rusty rotor shaft nut. I ended up wrecking the commutator. The heat went up the rotor shaft from the nut being heated and ruined the glue holding the segments in place. That one failed spectacularly.

I might try carefully using a large punch or rod, and giving the long bolt a couple raps. I don't want to crack the plastic end bell either rapping on the bolt.

If enough room, I tightly wrap a large soaking wet rag around what I want to protect and beyond. I have a spray bottle of water right there, so I am not tempted to do just a bit more as rag dries.
