PARTS FITTED TO 6.EX CAR. X3923 - X4544 1. Petrol Tank with Goshawk-11 side filler and level indicator. There is no arrangement drawing for this tank. The filler has been lengthened and the level indicator has been slightly modified to suit the 40/50 tank. 2. Dover steering wheel fitted to steering column. 3. Klaxon switch on steering column. 4. Goshawk -11 ignition and lighting switch made suitable for magneto and battery. 5. Goshawk battery ignition. We are using the standard Goshawk battery ignition unit. In order to do this we have had to reverse the rotation of the driving shaft. This also has reversed the rotation of the oil pump. * In order to avoid altering the suction & the delivery pipes on the oil pump, we have moved the bottom cover containing the relief valve, 180°, and also moved the pump itself round 180°. * a clever adaptation. 6. Earthed wiring throughout. Used in conjunction with Goshawk Distribution board. The wires are run in simplex steel tubes. 7. Standard Goshawk-11 dynamo.
