| c. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X235 BY/HEBY/M.27.9.28. PHANTOM CHASSIS. FRONT AND REAR HYDRAULICS SEC:7150/60. U.W. FRONT AXLE CONTROL SEC:7160. Kindly receive herewith one Blue Print of:- F.79481 Intermediate Lever(Hydraulic Damper) 2 off per chassis. F.79482 " " (Axle Control Damper) 2 " " " Kindly note these Levers have been strengthened up by making these 'H' Section, due to the failure of the present Production Levers on the Bumper Test. The Levers replaced by the above parts/are as follows:- F.74896 Intermediate Lever(Hydraulic Damper) 2 off per chassis. F.76382 " " (Axle Control Damper) 2 " " " It should be noted that with these Levers the same Bolts are to be used, F.75072 with the Hydraulic Dampers, and F.76383 with the Axle Control Dampers. Please produce the above Levers for the Bumper Test, and report on these so that if satisfactory these can be instructed at once on Production. BY/HEB.{H. Biraben} Jadg. | ||
