| X5360 RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}5/MA.6.5.32. 25 HP. BRAKE THUMPS. We want to get some central friction on the 25HP servo T lever. The attached sketch shews a method using 25HP torque reaction fabrics with the centres cut out. We can dispense with the central bush for this test. The friction should be 10 - 15 lbs measured at the T lever end. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
