Mike, I'm usually all for repairs but in this case it might not be practical. What make is it? what size 4½", 5", 7".
I would imagine that if parts were available it would be the whole armature and probably more expensive than a new grinder.
Once replaced a small bevel gear on the end of the shaft of a Wolf 7" grinder but after machining off the old gear (one piece with the armature) cutting a little keyway and fitting the gear it worked, but I never had confidence in it to really put a lot of pressure on it.
