Bailey - Chief Engineer} RHC.{R. H. Coverley - Production Engineer} E.5/HP.21.3.35. re Use of Lead Bronze Bearings on Car Engines. With reference to the above, we should be glad if you can tell us if any tendency to increased roughness has been noticed of power units on our chassis equipped with lead bronze bearings, due to the larger clearances that have to be used.
