| To BY. {R.W. Bailey - Chief Engineer} from Hs. {Lord Ernest Hives - Chair} c. to Wor. {Arthur Wormald - General Works Manager} c. to RHC. {R. H. Coverley - Production Engineer} X1770 Hs {Lord Ernest Hives - Chair} 2/LG20.11.28. 'SS {S. Smith} ' ENGINE - TIMING MARKING FOR FLYWHEELS. We have determined the best valve timing to employ with the 116° camshaft E.77322 and append a print shewing the necessary marking of the flywheel to suit this timing. We note that some of the flywheels are marked according to E.77934, which is the timing of 110° camshaft. Would you please make the necessary alteration to the drawings as per our print V.492 so that further flywheels can be marked suitable for the 116° camshaft. Hs. {Lord Ernest Hives - Chair} | ||
