Abstract
Abstract An improved arrangement is provided for mounting an adjusting ring lock strap with respect to a clutch cover to preclude premature failure of the lock strap after it has been properly secured to the cover by means of a threaded bolt. The improvement consists of a mounting slot formed in the clutch cover having tapered side walls engageable with the inner edges of the lock strap so that, in response to application of torque to the bolt, the lock strap reacts on the tapered side walls in such a manner as to provide positive frictional engagement which will prevent backing-out of the bolt.
