If you try to just pry it off it could damage the motor. If you have a small butane jet torch/lighter heat the gear and it will expand allowing it to slide freely on or off. Be very careful not to direct much heat at the motor or you could damage it that way too. If you have a vice you can clamp it in there gently to keep heat off the sides of the motor casing.
Edit: A soldering iron is a very good idea too. Safer and less likely to damage the motor itself.

Considering you are replacing motors, I assume you have access to a soldering iron. Use the iron to heat up the pinion, (not the motor shaft) and slide it off while it's still hot. Same concept as Azrael0987 mentioned, but easier to control where the heat goes.

I just pulled straight, and they came right off. OK, I handed them to my massive 200+ pound grip-strength roommate, who pulled them off. Make sure you have a good grip on the motors so you don't pull THEM in two. Heating can damage components- if you go that route, use a heatsink (pliers on the shaft or something.)

I may be late to this, but I have a very simple solution.
I use my Plastic snippers to wedge under the gear and push it up the shaft. Takes almost no effort and gets it off cleanly.

A little late to the party, but I thought it worth while to link to the proper tool for the task at hand. If you're doing a LOT of work with the motors one of these Tamiya pinion pullers might be worth your money to avoid damaging motors.

Capt Slug thinks this thread is idiotic. Why did any of you seriously reply to this?
