    Hi All,


    Can anyone help please?


    I have a 2018 R1200RT LC. Whilst trying to remove the valve core from the front wheel today the plastic (I know, I know) core removal tool broke leaving bits of plastic which won't come out. So I can't remove the core.


    Is replacing the whole valve stem easy enough? Looking at the parts fiche it appears that you can remove it without taking the tyre off.

    Has anyone done this?


    What is the torque figure when screwing it back on?


    Thanks

      Yes, it's straight forward to remove the valve from the side of the spoke of the rim.
      This is the part number for almost any BMW bike that has a valve at 90deg to the spoke, not the ones thru the center line of the rim.

      It does have factory anti seize (BMW calls it encapsulated) on the threads and that all needs to be cleaned off and something similar to blue thread locker used again.
      The torque for this is 12Nm as best as I can find...
      The TPMS sender is attached with a separate aluminum shear bolt from the inside, so if you have any little broken bits that went past the valve core, they could be lodged in this hollow bolt that allows air to enter the tire while filling/releasing air.

        Thanks for the quick reply.


        None of the plastic has gotten inside the wheel. The valve core hasn't budged.


        I've ordered a new valve stem so I'll take out my current one and replace it with the new one.


        I have thread locker and a torque wrench. It was mainly the torque value I needed as once I saw the valve stem I realised I could just unscrew it and replace without to much trouble.

          This is a very useful tool to have in your collection...
          As you can see it has a slotted end for removing the core, as well as a thread chaser for both inside and outside threads on a standard inflation valve.
          I never have used the tapered ream for the inside of the valve.
