| To RHC{R. H. Coverley - Production Engineer}/W.Bell. x1020 Hs{Lord Ernest Hives - Chair}/Swdl.{Len H. Swindell}8/JH.9.3.36. will you please look into the possibility of carrying out tests to determine the amount of oil which is fed from the bearing to the gudgeon pin. If it is impractical to carry out on the single throw Bentley crank which you have a plain revolving shaft with a Bentley rod attached would serve much useful purpose. Among the tests we should like the following. Comparisons between 2 hole feed in the bearing shell as standard and a single hole feed directly in line with the hole through the connecting rod. The quantity of oil flowing up the rod under free flow conditions. The flow from the .031 hole in the side of the rod with the gudgeon pin in position. HS{Lord Ernest Hives - Chair}/L.H.Swindall. | ||
