| R.R. 493a (50m) (D.B. 175 25-9-24) J.H.D. EXPERIMENTAL REPORT. -3- Expl. No. REF: Fig.111. X MEMBER Rod to indicate clamped to brkt. on Cross member. The deflection of the pedal shaft brackets were then taken and were found to be :- Clutch pedal bracket .0045" Brake pedal bracket .0015" Both brackets were deflected rearwards. -------- Fig.1V. Clutch pedal. Connecting link. Readings taken here. The deflection of the connecting link pin was tested from the same point on the clutch pedal as the clutch pedal deflection (Fig.ll.) -------- The deflection of the operating shaft lever was then taken for each ½" of clutch pedal movement (Table lll.) Table lll. | Pedal Movement. | Lever Deflection. | |---|---| | 0° | 0° | | .5° | .021" | | 1.0° | .022" | | 1.5° | .031" | | 2.0° | .032" | | 2.5° | .035" | | 3.0° | .036" | | 3.5° | .037" | | 4.0° | .038" | contd :- Fig. V.{VIENNA} Readings taken here.
