  • Patent number: 5404979
    Abstract: A manual transmission modular clutch assembly has a flywheel, pressure plate and interposed clutch plate mounted in a cover that is adapted to be connected to an engine crankshaft and wherein separate spring-torque straps connect the pressure plate and the flywheel to the cover for rotation therewith. At assembly the flywheel is positioned against the force of its spring-torque straps by travel limit pins that are retained on the cover, press fitted in the flywheel and contact with the pressure plate when in its clutch engaging position. A diaphragm spring normally clamps the pressure plate, clutch plate and flywheel together and is adapted to be connected to a clutch pedal to release the clutch. As wear occurs, the pressure plate is allowed to move further in the direction of the flywheel and forces the flywheel travel limit pins to move in their press fit by the same amount.
