Lidsey}5/KT.21.2.31. SHOCK DAMPER LOADS FOR L.H. CARS FOR U.S.A. In view of R's objections to drilled valves, it has been decided to reduce the leak in the H.P. valves on the front shock dampers. The final shock damper loads for L.H. P.II cars for U.S.A. are therefore as follows :- Front 110 lbs/110 lbs. H.P. valve drilled 1 hole .038" dia. Rear. 115 lbs/90 lbs. H.P. valve drilled 2 holes .038" dia. Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} | ||
