| TO BY. {R.W. Bailey - Chief Engineer} FROM E. {Mr Elliott - Chief Engineer} c. to CJ. c. to HS. {Lord Ernest Hives - Chair} ORIGINALS E2/M16.8.23. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. - FAN PULLEY AND DRIVE FOR SPRING DRIVE - LeC.1727. X4237 X4222 We send you herewith drawing No. LeC.1749., shewing the above. This is a slight revision of the spring drive for transferring the fan pulley back to the crankshaft. To do this it has been necessary to move the fan belt slightly forward, but there is no difficulty about doing this owing to the spare room available on the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) behind the radiator. In dealing with the spring drive before we added slightly to the length of the taper on the crankshaft front end without increasing the overall length of the shaft by recessing the crankshaft nut. If this alteration cannot be incorporated without interfering with interchangeability it need not be carried out. E. {Mr Elliott - Chief Engineer} | ||
