Abstract: This disclosure relates to a clutch actuating system having means for establishing initial free play without using an external gauge. A clutch system in accordance with this invention may have a clutch pedal, a clutch release lever and a Bowden wire assembly interconnecting the pedal and the lever. The sheath portion of the Bowden wire has one of its ends secured to a bracket adjacent the clutch release lever. The other end of the sheath is secured to the vehicle fire wall adjacent the clutch pedal where an externally threaded fitting in the second end of the sheath fits within a tubular housing bolted to the fire wall. The end of the tubular housing has four angularly spaced apart slots in its end face. A special adjustment nut on the threaded fitting has four axially extending projections arranged to engage the tubular housing. During initial installation of the clutch actuating mechanism, the adjustment nut is rotated to remove slack in the Bowden wire.
