| I. E - DEPARTMENT REDUCTION OF WEIGHT. X200 In making an examination of the engine with a view to reducing its weight it is seen that this project may not be easily accomplished by any local re-designing without sacrifice of efficiency. The employ-ment of lighter material for some parts presents itself as an alternative, but this is not always to be recommended as experience has shown that aluminum, sand or die finished, is liable to give trouble owing to its porosity. Rather by a detailed reduction in weight may the desired result be obtained: the removal or reduction in thickness of low-stressed metal. We may expect to find in some cases that the various components do not exactly follow the drawings, & alterations where possible could be made accordingly. The following parts might be made in aluminum:- Fan Bracket Low tension Mechanism Cover on Distributor Oil Catcher at rear of Magneto Drive Thrust at front of Magneto Drive Water Pump Gland Nut Clips for Magneto Wire tubes. Oil filler - Die cast with gunmetal bush for filling cap in position. | ||
