    http://www.bimmerboard.com/forums/posts/614482


    and a request from kikobojoe:


    Shogun has asked me to look into building a rebuild kit for a LAD shock. He recommended that I talk to one of you guys since you work with them frequently and may have the parts I need to machine. I have never worked on a LAD shock so I not familiar with the parts that are needed. Can any of you guys help?
    because he makes also horn button etc for motorbikes

    so if someone has an old defective LAD shock, please let us know.

    I'd pick up a pair of rear EDC top seals if you should ever give making replacement parts for the rear LAD or LAD/EDC struts. Apparently it's the top seal that's what craps out on them...

    Rear EDC III top seals I have. Just installed them 3 weeks ago.
    But for rear EDC III with LAD.

    So far so good. Have to order new ones, hope I can get more.

    We even made a tool for that, but it is not absolutely necessary, this one is a bit overspecification I would say.

    Someone on the M5.com board defined the seals and o'rings for the E34 EDC Shocks.

    They listed the part numbers and sizes and materials along with the manufacturer of where to source them.

    I looked into it briefly, but didn't persue the issue all the way. Manufacturers really don't want to bother selling a couple o'rings to individuals.

    I do know that if you have a Self Leveling Shock system, as in the '91 M5, and experience a slight leak when the car sits overnight, that replacing the accumulators will usually stop that leak.

    There is a rather lengthy procedure for testing the accumulators as per BMW, along with special tool # blah,blah,blah....but I thought you should be able to weigh the old accumulator and compare that weight to the new one. The bladder in a newer accumulator would push out all the old fluid where an older one with a blown bladder would still retain some fluid in the accumulator. Comparing the weight of an old one to a new one should show that an old accumulator with a blown bladder would be heavier because it still has trapped fluid, No?

    At any length, it's interesting to see the work that Erich has done and shared with the community. While the shocks are different from an E34 MSport compared to the E32, they share much of the same hardware. I believe they are just programmed a little different. Inside, I would be willing to bet that they are almost identical.

    Keep up the good work Erich, I would like to see more on the rebuilding of these EDC-3 shocks. If they can do it in the UK, we should be able to do it here across the pond.

    JR: can you copy this info from the M5 board?
    Testing the bombs is easy: just push a metal piece inside, if it goes down, sphere is dead, if full of pressure, sphere o.k.

    Also for this we made a nice video explantion how the thing works.

    Cutting that thing into 2 pieces was the hardest work

    It appears that all of the rebuild components can be purchased? No need to machine any parts? Is this what I am reading. Neither one of my vehicles have the LAD system. From what I read this is exclusively for the European market....Is this correct?

    Erich,

    Here's the link to the thread, read it carefully all the way through, I believe there is a typo on one of the supplier's email addy.

    Nonetheless, there are pictures of the seals and where they fit in the system.

    Let me know if this is the information you were seeking. I would like to keep tabs on your progress for my own benefit and for those on the board that use EDC 3 with LAD.

    Good Luck,
    JR

    Thanks Kibo,

    The second page is where the corrected supplier link is at, the first page shows the pictures of the seals and o'rings.

    Hope this helps some,
    JR
