I am restoring a G&B 177. The pump handle is frozen so I have tried to disassemble the pump mechanism from the pot. The cast iron ring has been removed but I cannot move the pump face. I am assuming it sits in a "race" and is corroded together with the cast pot.
I do not want to break the cast pot by being too rough on it. It looks like there has already been a bugger weld repair to the neck.
Any ideas to get this off? I am currently soaking the guts with ATF; previously I tried spraying PB Blaster. I don't think heat will work well as the pot is a huge heat sink.
I am not trying to make it functional but once restored, it would be nice to move the handle.
