    Smile Excellent animation of a DMF, it's components and operation!!

    I was looking for info on the dreaded DMF when I found this superb video:-

    http://www.youtube.com/watch?v=YnaXB8q3uzQ

    It shows the components and operation of the DMF clearly, so have a look its interesting!!

    Basically the dmf damps the vibration from the engine, particularly diesels.

    You can see why they are prone to failure!

    yep, it's the springs in them that give up..thats what makes them rattle...

    If you had a transit TDCI then ford say it's okay to have 11 degrees of rotational wear.....which is massive..

    LUK have developed a centrifugal type of DMF that it will be possible to retro fit, hopefully this design will prove more reliable. They have also developed a workshop tool to test the function of the DMF on the car, so possibly removing the need to automatically replace the DMF if the clutch fails etc.

    Thats interesting, but it's still a DMF with a modification. I can't see it being more reliable.

    True and sadly I cannot see the DMF going away whilst we have the old internal combustion engine (aftermarket solid flywheels are for a limited number of applications, which suggest they are not a solution), at least this demonstrates that manufacturers have ongoing R&D with the design rather than being stuck with the current unreliable spring loaded mass in the current design.

    Interestingly, I was reading earlier that most modern diesels cannot be converted to a solid flywheel as the vibration would destroy the clutch and gearbox anyway.
