| To Ev.{Ivan Evernden - coachwork} from Rm{William Robotham - Chief Engineer}/HH. c. to Rm.{William Robotham - Chief Engineer} c. to Jns. 1044 Rm{William Robotham - Chief Engineer}/HH.3/SW.18.9.41. B.60 Engine. Chain Driven Camshaft. PL.862 Mod. to PL.165 using existing camshaft. Rm{William Robotham - Chief Engineer} We have produced the above scheme in order that a Renold Duplex chain driven camshaft may be fitted to this engine. It was necessary to utilize an existing camshaft designed for single way thrust washer and spring plunger control. With the above scheme a single way thrust washer is used but the spring plunger control is replaced by a thrust plunger giving .004 end float by selective assembly.
