X.9660 - STARTER MOTOR Further to our E6/M91222, in reply to EFC5/T301122, we expect to have a 2" starter pinion engaging with a 16" flywheel - 8 to 1 - driven by the motor through an epicyclic reduction of 4 or 5 to 1. The exact figure for the latter will shortly be settled in designing the gear. Would you kindly pass this information on. E.{Mr Elliott - Chief Engineer} [Watermark: DICKINSON BOND] | ||
