| ORIGINAL Hsl/LG2.12.21. X4338 "GOSHAWK 11" - ELECTRICAL EQUIPMENT. We are sending to Mr. Royce a Bendix Drive which we are using on Goshawk 11., also the Bendix Drive off the Delco Starter Motor on the Marmon Car and also the Bendix Drive taken from a C.A.V. Starter Motor. We are also sending the Delco Buzzers off the Marmon Car. The trouble we have experienced with the Bendix Drive on Goshawk 11. car is that the screws work out which hold the ends of the torsion spring and also occasionally the pinion jingles against the gear ring on the flywheel. We think that to overcome this we should fit a little spring pad which is on both the C.A.V. and the Marmon Bendix Drives. In fact, we think we should make an exact copy of the standard Bendix. X3540 We also recommend that we chamfer the teeth of our gears the same as that which is done on all cars we have seen fitted with the Bendix Drive. We attach herewith a wiring diagram of the Marmon Car and also an extract from their Instruction Book as regards the functioning of the Circuit Breakers. With reference to the low tension wire to the R-R Contact Breaker, we recommend that we have an external terminal for this wire. If this is done the wire can go straight up with the high tension wires and look quite neat. We also think it would be an advantage because when the tappets were adjusted, the valve rocker cover with the coil, wires and high tension distributor, could be lifted off.
