If you don’t need to save the bearing race and have access to a welder then you can probably run 3 or 4 3/8″ long weld beads inside that race. When the weld beads cools and shrinks that also shrinks the bearing race so they usually fall right out.
If by chance it doesn’t easily pull out after the weld beads cool then just drop a large washer in on top of the weld beads then tack weld that in place. That allows a drift to drive it up and out from the bottom.
