Hardy - Chief Dev. Engineer} c. to Rm{William Robotham - Chief Engineer}/ ym. SV/JD.{J. Draper - Frames}5/KG.5.5.42. Austin 8 fitted with Myth engine. We attach to Rm{William Robotham - Chief Engineer}/HH's copy of this memo the following originals :- PL.1384 (2 sheets) Diaphragm Plate & Flywheel Housing. PL.1397 Clutch Actuation. The above schemes have been produced in order that the Myth engine can be fitted into the Austin 8 chassis. Rm{William Robotham - Chief Engineer}/ym. dropped the Myth engine into the Austin chassis and a position was found for the Myth engine, to provide a reasonable clearance between the dashboard and the front axle. The gearbox was moved rearwards about 2.000 which necessitated having a new propeller shaft length. The distance between the crankcase rear face and the Austin 8 gearbox front flange face, was measured and working to this dimension we have designed a diaphragm plate and flywheel housing to marry the engine and gearbox together. (See PL.1384, 2 sheets). The size and shape of the diaphragm and flywheel housing front face, is made to suit the Myth crankcase face, and the flywheel housing rear face is shown to match the Austin 8 gearbox flange. We suggest that the gearbox bolt centres and spigot require to be accurately measured by Rm{William Robotham - Chief Engineer}/ym. in order that the drawing office can ensure the flywheel matches up. It was found necessary to raise the starter motor to the position shown in order to obtain clearance between the motor and the cross in the frame. -continued- | ||
