You might fashion a puller with a bench vise. Position the jaws until they're narrower than the cup but wider than the bracket, and see if a little parallel pressure keeps it from binding up while you slide the cartridge out. Lube won't hurt, either.
Yes, I suspect this. Maybe I need to use more force. Your method might help keep it parallel and be the key. I have seen pictures of some Miche BB's in two pieces and the LH side seems to have a snap ring.
But if anyone can confirm the LH cup will slied of a snap ring, that would be great! Cheers...
