Ok, so as I pull off the final drive I find a quantity of oil in the swingarm. Damn I say, well I'm going to be ripping into the Gearbox again this year to replace a bearing I should have last time I had it apart (dont ask) and I can replace the shaft seal. Then I realize I actually have that seal from a previous order to MaxBMW, but I never installed it, good for me right? Well, after I pull off the cover, and unwrap the new seal (still in package) I realize its not even close to the one installed. I had figured the existing one was not a BMW replacement, but heres the kicker, The new one, with the proper # doesnt look like it will work. So anybody got one of these around to compare? Part# is 12312338514 # on seal is 1 338 514 I wonder if I got a bad part or what? see pics,green is one I had in, black is new one, note metal inner that does NOT fit the shaft.
