Hi, It is very difficult to dismantle the clutch unit. I know that it seems awkward to remove the clutch unit, ensure that you have removed all the small screws (some are rather difficult to find), lever the clutch operating coloured cover off, then make sure you have undone the 2 screws holding the clutch, then prise it out. It is not worth trying to repair it as there are loads of small components, a new one is about £18 complete with belts fitted.
