| To RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} XT/160 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KT.16.5.33. KELMIT BEARINGS - PHANTOM. The greater clearance necessary with Kelmit bearings has increased the oil flow through them. We therefore find that our existing P.II. oil pump cannot maintain the required pressure which we consider is necessary to give the bearings a chance. We should be glad if you would, therefore, make an oil pump to Hs{Lord Ernest Hives - Chair}/Std.7/KT.16.5.33. for test. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
