Whats chances you could drill into it at 180 degree opposing locations, switching to a quite low angle bit once started, drilling deep enough to hit the race, then use a 1/8" pin punch, tap it out 5 thou at a timeso as not to get it cocked & really jammed? Maybe even do it at 120 degree intervals so if you see it starting to get cocked, you could go to the high point & give it an extra tap to straighten it out again. Once its out, there will be a burr on the inside that can probably be set back flat with a slightly larger punch. Might not have to if the drill bit is traded for a 1/8" carbide end mill that can clean up, all the way to the face of the bearing race the chamfer the drill bit would leave. Then when seating the new race, stop about 1/32 from seated, clean the holes with spray carb cleaner and give it time to dry, then fill the holes with goop or loctites go-2, and finish seating it. It shouldn't leak for several years if ever if the shafts seals are good, and clean. It is certainly something I would try. Then I'd find out where Andy got that teeny little oil pump and fix your's like his is in the pix. I haven't had any similar problems with my 7x12, but it wasn't yet a year old when I took the controller screws out, which appears to be the only way to feed oil into that teeny casting. And I squirted an extra cup of 10w50 into it with a pump oiler. Very little weepage since then so I have to assume it still has the majority of that oil in it. Do you suppose thats why I haven't had a similar problem with the 7x12? It would not surprise me to see that it has the similar Christian Scientist oiling system. Its spent probably 50+ hours running at 2500 in high gear as I was polishing a steel shaft to the exact size at one point using 600 wet- r-dry, wet with k2 to do the final fitting.
