| 1113. E.from Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} c. Rm.{William Robotham - Chief Engineer} Cricklewood. June 2nd, 1937. P.III - ACCELERATOR MECHANISM. It has been pointed out to me that the accelerator counter shaft situated under the steering from the frame to engine tightens up due to the collapse of the tube when the two 3.BA. bolts for locating the pick up levers are over-tightened. These have to be dealt with at the Depot to adjust the setting of the throttle. It is a similar case to what happened on the cross steering tube ball joints.
