Bob, I've not seen one like it before either if that makes you
feel any better. How about drilling a lead hole and tapping the
"wedge" to get a bit of a handle on it?

If you do get to the bearings, they might not be anything standard
enough to find

My $9, much used, HF 4-1/2" angle grinder has a bad bearing. To
replace it I need to remove the spur gear on the end of the
motor shaft. The gear is threaded on, but has some sort of
retainer, I think. It kind of looks like a key, but it's not:
the shaft doesn't have a keyway & the shaft is threaded.

I haven't seen this before - could it be a wedge that was driven
in to lock it? If so, I suppose there's no way in hell that I'm
going to get it out (no access in the back and no EDM).

I hope I can fix it 'cause otherwise it's a perfectly good
grinder & why should I spend $9 on another one? Although I
haven't seen them for $9 in quite a while. $15 now, I think.
