Gearshift fork seal Stadion S11,S22

Special gearshift fork seal for Stadion S11, S22 engines. This is a special pressure seal in a steel bowl, which is custom-made. The seal has a ground edge for better assembly, but it is important to clean it well during assembly, or grind the edge on the crankcase as well - due to poor access to the engine block, assembly is not easy - but this also applies to the original seal. The original is a rubber seal in the block, which is held by a metal bowl - these are often already damaged or fallen out.
