Switching shafts sealing ring

servus, sometimes a question, am currently in despair, after several phone calls and contact reception by e-mails I still have no switch waves seal. somehow such a thing can no longer deliver or it takes and can not tell me when it is available. my seal below right that where the switchbar goes in is gone, now I have already tried a lot, but get it not dense and up to 8 weeks on a stupid seal I don’t want to wait either. has here still some dwer ne idea where I get the part? it’s not the simmering behind the scratch, it’s the din below what’s ripped. Part number 92049Bhttp://www.mrcycles.com/fiche_section_detail.asp?… or something you can still get that close to? so shit, must constantly put something under, because not just loses a little bit of oil. Or does anyone else have the complete Gus wall? to rebuild? Greeting and thank you
