I made this to replace the old paper gasket seals, that were leaking. These should be reusable, after you opened the BBSHD. I had some silicone leftover, from my hypercube build and designed three molds: Sealing for main steel gear (1,2mm) Sealing for controller (1,7mm / 7,7mm) Sealing for stator / engine (1,2mm) Silicone: I'm not sure, if it was the best silicone for this application, but it turned out nice.

Surface: Make sure, to have a clean flat surface. Otherwise the seal may leak:
