Noises when not installed are not a fault
Coil springs with different dimensions (length, material thickness and number of coils) are inserted into the torsional damper in pairs opposite each other. Due to the different dimensions, the springs have according play in the spring recess. The springs belonging to the first stage sit suitably in the recess, the springs belonging to the respective next stage are slightly shorter and, accordingly, have more play. When the clutch is not installed, the springs therefore move in the spring recess of the carrying plate and, as a result of the large play, may cause rattling noises. This is design related and is not a fault.
