ABSTRACT:
A compound flywheel assembly for compensating a wear on a clutch disc includes a first flywheel peripherally carrying a ring gear via which the assembly is cranked in starting the engine, afforded a certain amount of angular backlash; a second flywheel bearing the friction facing, connected to the first flywheel so as to be angularly fixed yet axially movable; a clutch wear-gauging mechanism provided peripherally in an end surface of the first flywheel opposite the peripheral margin of the pressure plate sandwiching the clutch disc; and an adjusting mechanism. The wear on the clutch disc is gauged by the clutch wear-gauging mechanism in contacting the pressure plate peripheral margin meanwhile the pressure plate is pressing the clutch disc against the second flywheel. Rotation of the ring gear through the backlash angle relative to the first flywheel by the engine-starting cranking torque causes radial advancing of the adjusting mechanism which effects axial movement of the second flywheel toward the clutch disc.
