Cut the rod off like Alan said. Then:

How much space is there between the motor and the rod? If there's enough space, get a piece of plate steel and mill a slot in it just slightly wider than the shaft diameter. Slide the exposed motor shaft into the slot in the plate so that the motor is on one side of the plate and the rod is on the other. Use a press to push the shaft out of the rod, with the plate providing the reaction force on the other end of the rod.

Yes. Like that.

Now find a strong steel tube with ID just slightly larger than motor OD, and slip it over the motor so the slotted steel plate rests on it and is supported all the way around.

Would it be advisable to use a soldering iron to heat up the Araldite? I found an MSDS to it if it helps.

If you have room for that slotted steel plate you can probably just push the shaft out with a press.

I get the feeling that we'll end up pushing it out using a hammer a vice and some sort of smaller steel rod. We don't have access to a press.

Set that slotted steel plate on that steel tube I mentioned earlier. Find a very short hardened steel rod. Hold the hardened steel rod with a pair of needle-nose pliers and bang the motor shaft out. Wear your safety glasses.
