The device operatively connects a threaded adjusting ring and an axially shiftable actuating collar such that wear occurring in the friction surfaces of the clutch is automatically taken up during operation of the clutch. The self adjusting device includes a mounting bracket secured to the clutch cover. The mounting bracket includes a central U-shaped portion and a pair of flange portions, each extending outwardly from an end of the opposing sides of the U-shaped portion. A pin is retained in the opposing sides of the U-shaped portion of the mounting bracket. The pin rotatably carries a pair of hub members which effect the self adjustment of the clutch to compensate for wear of the friction surfaces. The U-shaped portion of the mounting bracket permits visual confirmation of correct installation and function of the self adjusting device. | |
