If you have a welder run a light bead around the bearing and once it cools it will fall out. There may be a way to get an inside puller behind it - manufacturers usually leave a notch or something similar for just that purpose.

TOH
 

I'll just have to second the running a bead around the face of the race. After reading that method from so many guys here, I gave it a try, just chased a puddle around with a TIG welder (no filler rod), but a MIG welder would no doubt achieve the same result. Worked great, and that was after having no luck at all with a puller and bearing race installation similar to yours. I was surprised that a relatively narrow bead could shrink the entire race, but the proof has been in the results.
 
That's how boiler tubes are shrunk out you stick a 6010 rod down inside the tube stub and drag it up 3 sides of the tube the boilermaker would then squirt it with water and knock it out with an air hammer. When I was young I would go inside the boiler and shrink a hundred and the boilermaker would knock them out
 
Weld it out, run a bead around it with a welder the before it cools take two lady foot bars opposite each other pry on it, it will pop right out.
 

Welding will work but a simple pry bar will remove'em... Anything you can wedge under it and hit it with a hammer will walk them out...
 
I'd have it out with a 2 jaw slide hammer attachment before I could get the welder fired up. I kind of figure you wouldn't be asking how to remove if you had one though.
 
Put new cup in freezer over night.

Run bead around old cup. It should pop out easily.

Heat from welding the cup will slightly expand the holder. Freezing the new cup will slightly shrink it.

Apply thin film of oil to new cup, put in place, and lay a piece of wood over it and tap it in place
