| (5) is a function of the lead distribution at the surface of the bearing, although I have no definite information which shows that this is true. In the December, 1934 issue of the S.A.E., Mr. C.M.Larson describes a number of tests made with various lubricating oils on copper lead bearings. This, along with the work of Mr. Sibley of the Continental Oil Company, I believe to be the most accurate results obtained to date. Sometime ago, I requested Mr. Sibley to furnish you with a report covering the tests they had conducted on high lead bronze bearings. If you have not received this report, please advise me and I will see that you obtain it as quickly as possible. The Society of Automotive Engineers has established a special S.A.E. sub-committee to determine the effect of lubricants on bearing metals. This committee is made up of representatives of bearing companies, engine manufacturers and oil companies and is collecting at this time all of the information available on the effect of various lubricants on high lead bronze bearings. I am visiting General Motors Research Laboratories this week and if I obtain more information will forward you this information on my return." | ||
