| -2- Da{Bernard Day - Chassis Design}/JNR.{Charles L. Jenner}7/MH.{M. Huckerby}17.11.37. Water Pump and Dynamo. To be driven by a belt from the crankshaft, the dynamo being rocked about to form an adjustment. The dynamo being on the off side. By using the above, the spring drive will be deleted also the balancing cam device. The water pump to be mounted on the front of the cylinder block and to have a Packless Gland similar to the Vauxhall. Fan. To have a separate belt from the above, the object being to ensure reliability and long life for the dynamo and water pump belt. Distributor. It was considered that the Tower scheme was to be preferred because of its accessibility, and being remote from the petrol system, however, the heat from the exhaust system and the lubrication requires investigation. The alternative drive which is across the engine must be also designed and both be examined and costed. Camshaft. Four bearings having main pressure feed and the size large enough to take a cam lift of .375 which is demanded for the Power head engine. TIMING ~~Dynamo~~ Gears. Gears to be used. Fabroil for the cam wheel, and the centres to be arranged so that a chain can be substituted. (Rm{William Robotham - Chief Engineer}/Hdy{William Hardy}'s recommendations are that full depth at teeth should be used instead of stub). Gears and sprockets will be 1" wide and the pitch of the chain .5 to accomodate the Morse or Link belt. | ||
