    K1100 Clutch Push Rod Seal

    Hello,

    I have a '93 K1100LT that has a leaking clutch push rod seal. BMW doesn't supply this seal any longer. Does anyone know where I can purchase a replacement oil seal?

    Regards,

    Richard in Commerce Township, MI.

    Are you referring to the rubber boot on the back of the trans where the clutch rod comes out? If so, check with EME. I purchased one from them last fall for my LT.

    If you are referring to #23211451061, the seal in the back end of the input shaft and through which the clutch pushrod passes, that is a 9x15x4 seal and chances are very good that if you go to a hydraulic supply house or a bearing house they can source a seal that size. Make sure you note the orientation of the old seal as it is removed—the purpose of that seal is to keep trans oil from migrating forward and fouling the clutch.

    Maybe I'm not tracking here, but it seems the seal in question is BMW part number 23211451061, which is shown as available on the MAX BMW parts fiche for $13.73. It is the replacement for the earlier seal # 23211451159 and both are shown as 9x15x4 dimensions. What am I missing?

    I will say that I was impressed that the clutch rod boot (06 23 13 1 338 731) is $49.27! Be careful with that little jewel.

    Yes, good catch! RealOEM is showing that number as ENDED, with no substitution available:

    Shaft seal 9X15X4 1 23211451061 ENDED
    Part is not longer available
    No alternative component available

    Hopefully the part is actually in stock at MaxBMW and not an inventory error. And hopefully RealOEM will update their fiche.

    Or vice versa...

    Edit: Bob’s BMW is also showing that seal NLA. If true, I hope this is a temporary situation as that seal is used across all the early K-bikes...

    Best,

    Greg - If I found the clutch rod boot someplace other than a dealer, for less money, do I get a finder's fee?

    Max only updates their Classic bike parts fiche once a year. So, if the part was discontinued during the past year, it would not yet reflectedon their fiche. This is true for both price and availability.

    If you can't find it at one of the US BMW sites, they have them in the UK. I can't remember if I got mine from Motorworks or Motobins. I got one of those small seals from one of them and just replaced mine a couple of months ago.

    Select your bike. Select Gearbox. Should be sixth row middle column.
    Around $18 US with shipping.

    So $9 less if you don't mind the wait (which is longer than normal due to Covid). The $27 Ebay one would probably be quicker.

    So, what is anybody's guess of how long Motobins or others will have this seal available? Is it prudent to stock up on a couple of one has a K-bike collecting habit?
