How are folks going about restoring original flapper boxes?
I had intended to bead blast and powder coat ours. Preparing to degrease them today, I see that they have a spring mechanism inside and what I think is a rubber sealing ring. I don't think those would much like the powder coating and required heat. Some other styles talked about on other forums get disassembled, but I don't see a way to get those components out without destroying the housing. Perhaps bead blast and spray can is the best bet, and just accept the spring and sealing ring will get painted? Thank you. P.S. I've seem some discussion suggesting 914-6 were gray rather than black. Was that ever definitively answered? The color of ours is rust. (IMG:style_emoticons/default/sad.gif)  |

I replaced the gaskets on one using some exhaust gasket from the FLAPS and high temperature adhesive. You can't really restore them exactly like original because the gaskets are crimped into the flapper around the edge. But mine have held up and make a good seal.
Here's a bit on the process from my build thread, but pretty straight forward. |
