For case 1, many people grip the weight in a vise and use a small pin
and hammer to tap the shaft out of the weight. Make sure you have
something to catch the motor so it doesn't bounce off the floor. Watch
out for small spacers between the weight and the motor that you might
not want to lose. This method won't work for case 2.
For both cases, you can try to break the weight. One successful approach
(reported by others) is to crush the weight in a pair of vice-grip
pliers. Personally I like a device (which I happen to have in my tool
kit) called a "nut-cracker". It's designed to split seriously rusted
nuts off bolts that you don't want to damage. Bascially it has an anvil
which you place against the nut (or weight) and opposite that a hardened
steel wedge mounted on a screw. Tighten the screw with a socket wrench
and it drives the wedge into the nut or weight, splitting it neatly
apart. Other people have used carbide or diamond cutters mounted in a
dremel machine with good results.
If you try the first method on a case 2 weight, you will almost
certainly wreck the motor. The other three methods will work for both
methods of mounting the weights, to you might want to try one of them
first just to see how the weights are mounted.

This has been discussed on-list a number of times in the past - I'd
suggest doing a search. The predominant methods seem to be either
crushing the weight to crack it, or clamping the weight in a vise and
driving the motor shaft out with a pin.
