| 20 To EA. [struck-through] from E.{Mr Elliott - Chief Engineer} Copy to C.C. " " B.H. " " F.H. ORIGINAL E2/G7/8/19. 2 EFC.X.3310 RE CAMSHAFT DRIVE - 20 H.P. CHASSIS. We send you herewith drawing No. Lec.1120 shewing the above. The camshaft casings are connected together at their front ends by the unit shewn on Lec.1120. At their rear ends they will be connected by a yoke, so that the complete camshaft and rocker mechanism, together with the gear box containing the worm drive, will form a unit which can be lifted off in one piece from the top of the cylinders, when it is desired to remove the cylinders for the purpose of scraping out the carbon from the combustion heads. Would you kindly put in hand the necessary pieces for Lec.1120. You will notice that a small modification is required to the fan bracket recently sent through.
