Disc-packet unit that can be mounted and method for mounting the same

A disk packet that can be mounted on a guide element of a transmission component, comprising:

• a pre-tensioned disk packet comprising at least two adjacent arranged elements that form frictional surfaces which can be connected in a frictional engagement with one another by means of an intermediate element that forms a frictional surface and an auxiliary mounting device;
• at least one spring device located between said at least two adjacent arranged elements that form frictional surfaces;
• the auxiliary mounting device comprising at least one sleeve element that can be coaxially mounted on the guide element of the transmission component and a tensioning device;
• said elements that form frictional surfaces being guided on the sleeve element;
• the sleeve element comprising a stop;
• and
• the tensioning device being connected detachable with the sleeve element and creating a force for pre-tensioning the disk packet so that static friction is generated between said elements that form frictional surfaces and the intermediate element.
