| -2- Valves & Fittings. Detail one piece rocker shaft, new pedestals and distance piece. A new rocker cover is also required. Camshaft. There is some doubt about the camforms and angle between cams. Oil Pump. An oil pump with reduced capacity is being designed and should be available in a few days. Petrol Pump. New drawings required for increased strokes to design recently issued. Exhaust Fittings. The design of a resonance type of rear silencer will be issued immediately. Radiator Shutters. The oval section shutter will be replaced by a tube section on the lines of our present design. On all future chassis the bonnet will be lengthened 2 inches by continuing the existing panels further rearwards. Starting Handle. Correct the spring loading to give similar action to those on production chassis. 1st, 2nd, & 3rd Motion Shafts. Modifications may be made to the 1st. speed gears to reduce the stresses. Reverse Gear. If the new design of reverse gear means much modification to the gearbox, so as to cause delay, the existing one should be fitted. Rear Axle. The centre portion will require re-designing to suit the larger diameter hypoids recommended by Gleason's, at the same time the removal of the pinion and housing without disturbing the crown wheel setting, will be looked into. It is assumed the axle tubes, shafts &c. will remain unaltered. Front Axle. Axle control must be fitted to all chassis. Frames & Fittings. The engine front suspension will require some design work, but to avoid delay it is proposed to order asfor the first chassis. | ||
