x7060 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Smth. 20/KW. 4.12.34. Ph. II - Silent Tappets. We have now confirmed that the .CC125 clearance hydraulic units are satisfactory on 28-EX. Although there is no prospect of silent tappets going into production on Ph. II, we consider that it will be advantageous to get as much experience as possible with them, and should like to get another set running on Sg{Arthur F. Sidgreaves - MD}'s car. Will you therefore modify the clearance of one of the sets you have in hand and build up a head to the same specification as that on 28-EX. Hs{Lord Ernest Hives - Chair}/Smth. | ||
