I will try to think that through. I got the seal out with heat. I got the allmium so hot the seal caught fire and when enough had burned away it jus fell out.

I wonder of dry ice on the bushing would help. I'm thinking put the dry ice on the inside bushing for like 10 seconds , before the alluminum has a chance to get cold ..... like 10 seconds. When the bushing shrinks against the alluminum tap it with a hammer. and maybe it will fal out. I'll let you know if it works.

Metals expand and contract at dirreent rates.
