| To RHC.{R. H. Coverley - Production Engineer} x140 x754 Hs{Lord Ernest Hives - Chair}/Smth.13/KW.7.11.34. Ph.II. Oil Filter - Auto. Adj. Tappets. On examining this filter on 28-EX after 10,000 miles, we find that the oil pressure has collapsed the gauze and given rise to longitudinal cracks in it. It is evident that the gauze should be supported in some manner, and Hs.{Lord Ernest Hives - Chair}1595 shows a way of doing this. Will you please make us a filter to Hs.{Lord Ernest Hives - Chair}1595 for 28-EX and also for any other sets of Ph.II silent tappets which you have in hand. Hs{Lord Ernest Hives - Chair}/Smth. | ||
