| To BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} c. to Wor.{Arthur Wormald - General Works Manager} X7060 'SS{S. Smith}' TAPPET CLEARANCE ADJUSTMENT. X516 Hs{Lord Ernest Hives - Chair}4/LG28.11.28. We find the thread on the tappet adjusting screw E.77712 is too coarse to permit easy adjustment of the tappets to fine limits. These screws are 22 threads/inch. We recommend that this part is altered to have 26 threads/inch. Hs.{Lord Ernest Hives - Chair} | ||
