| 607 BY {R.W. Bailey - Chief Engineer} /HS. {Lord Ernest Hives - Chair} C. H. {Arthur M. Hanbury - Head Complaints} DA. {Bernard Day - Chassis Design} 1/G.21.1.38. WRAITH 111 and BENTLEY 111 - SPRING LOADED THRUST PLUNGER FOR CAMSHAFT. Please receive herewith R.CD.402 Camshaft Spring Loaded Thrust Plunger - Wraith 111 and Bentley 111. The Experimental Department have already tried a similar scheme EX.28216 to reduce rattle in the timing gears, with some success, and the design R.CD.402 shows the proposed method of applying the scheme for future engines. The camshaft and the wheelcase are slightly altered to accommodate the plunger. Will you please detail and instruct this job experimentally as soon as possible.
