Walker - Patents} -------------------- X254 EY.16/G.26.11.34. BENTLEY - VALVE TAPPET CLEARANCE. --------------------------------- The Experimental Department as the result of a series of long period testing wish to reduce the clearance on the Bentley exhaust valve tappet from .006 to .004 for use in England. For Continental use they wish to retain the present clearance of .006. The objection to the larger clearance is one of noise. BY.{R.W. Bailey - Chief Engineer} | ||
