X.4150 DOUBLE THRUST BEARING IN REAR AXLE. Whilst I was in the U.S.A. I saw a sample of very badly worn distance piece from the thrust housing for the rear axle pinion. The wear appeared to be due to the reverse thrust with the Gleason bevel gears. We are sending the worn distance piece to Mr. Royce. We attach herewith standardisation sheet for the double thrust bearing which was held up for tests. We have now run an axle fitted with the double thrust bearing for 450 miles. The arrangement is quite satisfactory. We recommend that we immediately standardise this double thrust as before any of these are delivered to customers, we shall have completed several thousands of miles on an experimental car. Will CJ. and BJ. sign the standardisation sheet if they are in agreement. Hs.{Lord Ernest Hives - Chair} | ||
