A friction clutch wherein the mechanical advantage or lever ratio can be varied without changing the construction of the release levers. This is achieved by changing the location of the pivot pins that connect the levers to the pressure plate, and by elongating the release lever holes through which the pivot pins pass. Changing the location of a pivot pin with respect to its supporting lugs on the pressure plate will cause a change in the location of the pin along the length of the elongated pivot pin holes in its corresponding release lever, and this in turn operates to change the mechanical advantage exerted by the lever on the pressure plate. |
