An automatic wear compensator for a vehicle clutch actuated by a diaphragm or Belleville spring to compensate for the normal wear of the clutch friction faces during use and maintain the initial load characteristics of the spring throughout the life of the linings. The adjustment is accomplished through a rotatable pivot ring operatively connected to the pressure plate and adjusted through a series of camming surfaces, thus retaining the fulcrum surface for the spring on the pressure plate at a substantially constant position in the clutch assembly and maintaining the installed position of the diaphragm spring. Also, a self-adjusting stop is provided for the pressure plate to limit retraction thereof and allow adjustment of the pivot ring.
