Yep,, gotta get that off,, If youre not equipped with a heat source,, youre gonna need to be,
Do you have a good vise. hammer, chisel?
You can get a torch head at Lowes,,

Id heat a section of that racewhile its in the vise, and, using just about 1/2" of the Sharp chisel, knock a groove in it, Ohh,, Id Start by grinding, at least get the edges cut down, and if you have a cut off grinder, you can seriously
affect the structural integrity of that bearing race..
Anyway. the object is to make that bearing race grow.
It grows with heat,, but shrinks again,, If you heat it, you can bang on it, anything, chisel a line across it, that makes it longer, which make it loosen up.
IDK what goes in the slot that I see is misshapen,,If thats inportant to have it looking as much like it did before that metal got mashed outta place and something is supposed to be IN that slot,, Dont just grind that metal away. Itll peen back into place,, with a buncha light hits. Then grind,file, whatever.
And that aluminum isnt gonna like getting too hot,
And its a heat sink, making your job harder.
If youre not up to it, a welder can handle it,,
