I'm in the process of changing my shift shaft seal. Upon inspection, the seal I got from the dealer looks different than what I've taken off the bike. The old seal has a different profile insofar has how it mates to the shifter shaft. Also, the profile of the new seal has a different detent on the inboard side. I'm hesitant to put the new seal on and have it leak and have to do the job over. I know sometimes BMW will improve upon a design...The old seal # is BAD 16-26-7. On the opposite side of the seal there is a "4". The new seal, as far as I can read it looks like BMW 1 338 740 BFW 1 16-26 7/6.
Any suggestions? I could take both seals back to the dealer tomorrow, but if anyone knows if this is an improvement over the old seal design, let me know....1975 R/60/6
