But, I strongly suspect your motor shop doesn't have some fantastic fixture to do this, either! In general, you can remove bolts that hold the end covers to the stator housing and use a puller to pull the end cover off with the bearing. Then, push the cover back and the bearing will be left exposed on the shaft. Pull and replace the bearing, and reassemble. If you are gentle with it, you can probably avoid much chipping of the magnets, and the motor should be fine.
It may be important to remove the encoder before any disassembly of the motor, depending on how it is put together.
