    Default DMF - Dual Mass Flywheel

    I have to get mine changed next week under Network Q warranty.
    Is it a big job?
    What is the DMF? and what does it do?
    Why would it need changing?

    Cheers!

    it's the dual mass flywheel....they are no longer solid but now made in two parts.. the damping springs between them fail and it rattles and judders like a swine..

    is it a big job?.. yes... subframe out, gearbox out ... not one to do on your back at home...

    I did mine on my own, on my drive, on my back and at home. Even got the dam gearbox back on with no help, that was a sod!

    what i meant was it's not one you'd catch me doing at home.....

    top respect for doing it. ..the boxes can be a git to fit when up in the air let alone when on your back and alone...

    It really was hard, I didnt think it was going to be possible to get the gearbox back on. All the angles to use your strength are working against you. I had to use my legs and all the strength I had. As you will know, its the weight but also getting the dam thing aligned up to slide in too!

    I also never used a clutch tool! lol

    You will be used to nice working conditions, so I can understand how daunting it sounds to work on a drive. I obviously had no choice.

    Default DMF - Dual Mass Flywheel

    Hi All

    A colleague at college had his go on his Ford Focus Diesel, the radial spring had weakened allowing over two inches of play between the masses. The thing is we both tow caravans, I was just wondering if this is a factor.

    I honestly don't think towing a van would cause premature failure, unless you really abuse it IMHO.

    Default DMF - engines ...

    Anyone know if are they fitted to the full range of engines, or are they diesel specific?

    the material between the two steel parts is made from a rubber compound allow some seriuse heat into the system (from say a sliping clutch) the rubber will melt and the flywheel will rattle / go faulty ..note the 19's have a built in fault so they fail due to the drive haveing a cold ...lol ...
