    Given that the seal is listed as ENDED rather than “backordered, no delivery date specified”, I would hazard a guess that these won’t be reissued by BMW. That said, a shipment could arrive tomorrow for all we know. If you’re worried about it, lay in a couple. That seal is a unicorn, I think—I’ve not been able to find a non-BMW source for that size.

    Just did that this morning. I ordered 5. I need them because I replace transmission input shafts on peoples' transmissions that have neglected their clutch spline lubes.

    The bean counters at BMW have taken control of inventory the past few years. More and more they are refusing to remake out of stock items for the older bikes. Not like the "good old days" afew years ago.

    Hello,

    First I'd like to thank all the people that responded to my original post.

    My local BMW dealer told me on Monday (3/15/2021) the push rod seal is no longer available and that BMW has no plans to supply it. I called Euro Motoelectrics and they are out of stock. Today I called Max BMW and they said the part is available, so I order the seal. Hopefully I'll see the oil seal in the near future.


    Regards,

    Being an older dealership with four locations, plus the fact that that seal fits so many of the older Kbikes, it's not suprising that they still have a few on the shelf.Yey Max!

    Well, nature abhors a vacuum... I wouldn't be too surprised if someone in the aftermarket starts to manufacture these for sale though places like Motobins, EME, and other non-dealerships (especially now that everyone is seeing this thread and immediately buying all of the remaining ones on the shelves, signalling the market there is a new demand...).

    Good plan. I think I will get a few myself.

    Hello,

    I received and installed the clutch push rod seal and a new clutch plate. Now I have another problem, the new lock washers under the clutch housing cover blots (6) are splitting. When I torque the bolts I can feel the washer crack and in one case I heard it split. I wasn't even at full torque. Maybe 12 ft-lbs when they split.

    These washers were bought from the dealer. What to do?

    McMaster-Carr has 7mm external tooth lock washers, both zinc plated and 316 SS. Should I try them?

    Thanks again for your help.

    Regards,

    Richard Flood, Commerce Township, MI

    If the dealer is close by, maybe present the washers and explain what’s happening and see about replacements—if you want to go to that length. Otherwise, yes—try the McMaster washers. I have found their hardware to be of fairly good quality, quite possibly better than what the young MBA bean-counters at Motorrad are sourcing now. ☹️

    Hello DeVern,

    I live about 25 minutes from the dealer I purchased the parts and 35 minutes from another. I guess I'm lucky in that regard.

    I called them today and the parts guy is going to talk with their "Older K Bike" mechanic on Monday and see if he has any insight. The only thing is that if I get more washers from the dealer and if they came from the same batch, then they will crack also.

    Regards,

    Richard,

    Do the clutch bolts fit snugly in the washer hole or are they a very loose fit?

    A loose fit (like a size too big) could cause the force to be uneven on the washer, causeing it to break.

    Hello Lee,

    These are all OEM parts. The washers that didn't break are now elongated. Tomorrow I'll measure the long and short ID and come up with a average ID measurement.

    Regards,


    Update Lee, the washers fix bolts correctly.
