    Just a idea!
    You may have to remove/ free up the clutch actuator?
    Maybe the garage install it wrong , to far in the gearbox (too much tension)?
    Thats maybe why the clutch wont work.

    What they told me exactly was : 'Looks like the cluth is too thick. When we refit the gearbox the cluth is constantly disengaged.' You think this might have caused that ? I don't expect my engine/gearbox to be any different than any other in a smart, so they must be doing something wrong But because I don't have any experience with that now I look like a guy that tries to fit a part that was not meant for this car. Thanks for all the ideas. I'll sync with them on monday. Maybe for a temporary solution I'll just ask them to try fitting the old cluth with the new flywheel.

    Where did you buy the Bonalume clutch kit?

    Take a good look at the websites of SmartKits , Bonalume , S-mann.

    SmartKits has a 4 parts clutch kit
    Bonalume has a 3 parts clutch kit
    S-mann has a 3 parts clutch kit

    Maybe the problem is the 4 parts SmartKits clutch kit.
    If so, contact SmartKits.
    They can explane how to install the clutch kit.

    I've a 3 parts Bonalume clutch kit from S-mann.
    I've never had any problems, I even swapped over on a other engine.

    Good luck, keep us updated

    I got mine from S-mann as well. Ok thanks for your help mate, I blame the garage since they've never worked with any performance parts for smart

    Did they remove the clutch drive plate?

    or the problem is by the Clutch Release Bearing Assembly

    Its very simpel to install the Bonalume clutch,
    Yeah , you've to replace the Starter tooth ring on th ergal flywheel.

    Check also the bearing on the drive-shaft , before you install the flywheel.
    Use some sandpaper , for the centre-hole in the flywheel.
    Then its easyer to install the flywheel.

    Good luck with the install

    Oh gosh, I really hope they haven't missed something as obvious as the drive plate And what can be the problem with the release bearing assembly ?

    So tom I'll ask them to check :
    - clutch actuator
    - drive plate
    - clutch release bearing

    Thanks for your help ossy !

    Am I missing something?
    What makes you think a smaller diameter clutch will transmit a higher torque?

    I think it's about the weight of the flywheel and not clutch. Lighter flywheel will let engine to spin up faster and probably get more power but at the same time with less torque.
