To replace a bearing I need to first remove the old bearing inner from the
shaft.
There is almost nothing for a puller to grip so propose to weaken the
track
by grinding it and then fracturing with a chisel.

For this application, what is the correct abrasive wheel for a bench
grinder,
Fine Grey, Green, Pink or White?

Whichever one your bench grinder already has fitted. It's hardly going to
make a rat's arse worth of difference for a single bearing race. An angle
grinder with a cut off disk would probably be the better tool anyway. It
might come off if you belt the back of it with a blunt chisel first though.
