Thomas of Bijur - Feb. 5/30. Discussed (a) possibilities of extending the application of the Bijur system on PI and PII. (b) other present types of chassis lubrication. EXTENSIONS OF PRESENT SYSTEM A.{Mr Adams} (1) Extension of system on PI to lubricate sphere and torque tube. Successful on MX{John H Maddocks - Chief Proving Officer}-5. Desired as a service-fitting to eliminate present oil-pot under bonnet. Discussed details and prices with Maint Dept. and Btn. Mr. Thomas is not quite satisfied with the extent of our tests. Thinks we should make check tests in cold weather to verify the amount of oil collected in sphere and torque tube in say 750 miles running. Collect in bottles as on original test. This should be done soon to give further experience on which to base service fittings. (Also see later notes re sphere lubrication on hand-system.) (2) Extension of system on PII to axles. Mr. Thomas would no longer recommend taking the brass pipe through clips attached to the springs as we do. Because it requires machining the edges of the spring leaves to make sure the clips will stay on, and unless pipes are very solidly clamped or soldered to the clips, chafing will occur. Considers the best system as used on the Stutz, namely a short vertical downward coil on the frame, and a short vertical upward coil on the axle, with a length of horizontal pipe between them, removed by two or three inches towards the inside of the frame from the road spring. Considers this better than the simpler rubber pipe scheme used on cheaper cars, because in time the rubber pipe must give out whereas the brass pipe is in practice as permanent as the chassis and does not suffer from stone-damage even on a low car (like the Stutz. - continued - | ||
