Harold Whyman - Experimental Manager} JBD.{John B. Dixon - Fuel Systems} Wst. CUSTOMERS' COMPLAINTS. Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}2/R.26.2.37. P.III. With regard to the attached memo, please fill in what is being done to overcome these troubles other than what GWH.{George W. Hancock - Head Chateauroux} mentions:- Wst. (1) 28 Electrical Failures. Dynamo fuse failures presumably due to old type fuse. Improved fuses are now in circulation. Swdl.{Len H. Swindell} (2) 23 complaints of engine due to poor slow running. The cause is mainly by plugs oiling up. The following is being tried (a) More clearance inlet valves, (b) External drains (c) Packing up of valve gear. (d) Increased plunger clearance to reduce tendency of valves to ride by hydraulic mech'. Smth. (3) Jaggering Clutches. Most of complaints have been on B.B. plates. These are changed for R.R plates which appear to be slight better. May have to go to still axle & prop. shaft damper to get cure. Wst. (4) II Failures of Instruments. Makers modifying trip mechanism on speedometers. New type of instruments and drives being tried out. G.R. (5) Sticking Throttles, 8 cases. Present spring overstressed. New spring under test on 36EX. Les.{Ivan A. Leslie} (6) Hydraulic Dampers. PRIII connecting links are instructed to have 1/4 bolts to replace 2BA Stiffness in control - Rock control Lec 5498 replaces arens. Knocks? Manufacture is greatly improved. Armstrong Oil loss? Dampers should cure these troubles. RM{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
