Rebuilding a Curtis Valve
I have a Curtis quick drain on my Cub. It was moist from seepage at the seal. After an unsuccessful and extensive search for a replacement sealing washer, I called Curtis direct. Talked to a great guy about it. He said that they did offer them at one time. The problem was that some customers were trying to disassemble the valve and then re-rivet it together with the new seal, instead of just picking the seal out with a scribe and installing the new one. I assured him that I had no problem in removing it and just wanted a replacement. His final comment was that they may look into offering a rebuild kit that would include instructions and a simple tool for the job. I really think that it a legal vulnerability issue. Anyway, bottom line, I just bought a new valve. Sorry for the bad news.
