Heat gun to melt the rubber so you can then carefully scrape it out the rubber with picks? When that rubber is broken down /removed adequately the metal structure will come out.
Another good suggestion. Thx.
I wouldn't waste my time with a heat gun at this point and go straight for the mapp or propane torch and heat and burn the crap out of it. After all of the rubber is burned off and what ever "glue" or Loctite was holding the metal ring in is burned away, I would let it cool and then heat the case around the outside of the seal (with a torch) and pry it out with a seal remover tool. No sense at trying to be nice to it at this point
GET THE TORCH out!
