The part that usually fails is the diaphragm inside. We've had several discussions about upgrading to a better diaphragm material.
If you look at some of the photos of a dissected AOS ,you'll see where the diaphragm is located and the mode of failure.
My idea was to use a new Viton diaphragm. It can be made from Viton sheet .The problem is the adhesive. Viton is a peculiar material and the only adhesive I can find is :3M 5200 polyurethane sealant. The seal would need a mechanical clamping method also?
A contributor on another Forum says he uses an upgraded seal from BMW -but gives no specifics.
I just need a failed AOS to do some trial surgery on.
