An automotive clutch comprises a flywheel fixed to a driving shaft, a friction disc fixed for a rotation with a driven shaft, a pressure plate fixed for rotation and axially movable with respect to the flywheel and a diaphragm spring bearing against a fulcrum on the cover for urging the pressure plate towards the flywheel axially clamping the clutch disc. Precision centering and securement of the cover on the flywheel are provided by machining a recess in the skirt of the cover in precision fitting relation with the cylindrical periphery and a faced annular surface on the flywheel and crimping the skirt to the flywheel. The precision centering of the cover ensures the centering of components such as starter ring gear. |
