Re: Henry's 55 Constellation

thought it was a good time to do something more mechanical. so i took apart the BTV unit for cleaning and rebuilding.

here are a bunch of pictures showing where everything came from and/or goes on.

the canister seems okay, but the piston has pitting and a vice grip indention as does the piston on the end of the push rod.

looks like the bleed back hole was closed off by the plate gasket.

also note that the vacuum hose was wired on to keep it from coming off for whatever reason.

this unit has obviously been broken into before. i have no idea what that grey washer is on the compensator valve either.

the diaphragm is original it appears by the date. I also have no idea what that gooey fiber material was between the floor plate and the canistor top. i guess to keep water from getting into the car idk. i'm guessing some black rtv will be a suitable replacement.
