A diaphragm clutch cover assembly is disclosed comprising a cover having a peripheral flange secured to a flywheel, a diaphragm spring, assembly means rockably mounting the diaphragm spring on the cover between axial spaced fulcra and axially applying a predetermined resilient clamping load, and a pressure plate fixed for rotation with and axial displacement in relation to the cover. The resilient clamping load on the diaphragm spring is selected between the peak value of the release load on the diaphragm spring at the minimum reference value and the greater of the final value of the release load at the minimum reference value and the final value of the release load at the maximum reference distance. In the coarse of service life the diaphragm spring breaks contact with one of its fulcra when it rocks from its engagement position and its disengagement position.
