Good to know. I have seen those gaskets in place more times than not (in my limited experience mind you). Just always assumed they belonged there. Guess I should look at manuals and diagrams more as opposed to just winging it.captain wrote: ↑Sun Dec 16, 2018 11:16 amThose valves do not use a copper gasket on the bonnet nut, it is a metal to metal seal. Sometimes you have to tighten and loosen the nut a few times to reform the metal to metal seal. If you find a copper gasket it's because someone thought there should to be one.
I haven't tried drilling one, but I'll try to measure the hole with index drill stems and let you know what it is.
The hole in a new unused seat is the size of a wire gauge drill #63, which is 0.037"antique diver wrote: ↑Sun Dec 16, 2018 2:49 pmI haven't tried drilling one, but I'll try to measure the hole with index drill stems and let you know what it is.
I could not find the bulletin pertaining to that seat issue. I do know there must have been a specific reason for the hole only being needed on the J-Valve and not the K. I never did figure out the physics of why, and it was not fully explained in the bulletin. Seems like I must have lost a whole notebook of extra info like that, but if it turns up I will post it.
