Trot Salt - Carburation} Rm{William Robotham - Chief Engineer}/Swdl{Len H. Swindell}1/R.30.12.36. PROGRAMME OF TEST BED WORK. FURTHER TO MEMO Rm{William Robotham - Chief Engineer}/Swdl{Len H. Swindell}12/AP.14.12.36. NO.5 TEST BED. PHANTOM III. No.9 Unit. Preparatory run on bed for fitting in 35-EX 15,000 chassis. Alternate cylinder liners are RR produced and remainder are standard Sheepbridge. New big ends 3 RR W/M, 3 Hoyts Z3. Main bearings with exception of No.2 & 3 intermediates which are RR, are Hoyts Z.3. 4 Port cylinder heads and alum. hot spot. LeC.5319 camshaft with long toes to suit deletion of automatic tappets. "Low carbon" American design springs, and " " made springs to RR. design. Strengthened S/SLV (non stellited) and " KE.965 (stellited). The following is a list of jobs which should be carried out:- (1) A record of valve timing on A.1, A.6, B.1 and B.6, to be taken with .027 clearance. (2) Note valve noise when set at intended running clearance of .006 In. and .008 Ex. with warm engine. (3) Observe for piston knocks starting cold. (4) Slow running and power curve. (5) Observe push rod and valve tip lubrication. Push rods should have an ample supply. Valve tips should only have slightest amount of oil. (6) Check for over-oiling at low speeds and a 1 hour run for oil consumption at 4000 RPM. | ||
