In a wear-compensating arrangement for a pull-type clutch assembly, the fulcrums on the cover (14) which engage against the diaphragm spring (22) adjacent to its outer periphery are movable axially of the clutch assembly, being urged by springs (57, 58) towards the diaphragm spring (22). Each moveable fulcrum (50) is of arcuate form and is split circumferentially into an outer part (52) which engages the diaphragm spring (22) when the clutch is engaged and an inner part (53) which engages it when the clutch is disengaged. Unidirectional jamming means (59, 60) between the two parts (52, 53) and the cover (14) permit movement of the parts towards the diaphragm spring (22) but prevent return movement, so that on operation of the clutch the two parts (52, 53) of each fulcrum (50) can move sequentially towards the diaphragm spring (22) to compensate for any wear in the clutch linings.
