| -5- He/GWH.{George W. Hancock - Head Chateauroux}6/KT.16.1.31.Cont Item (25) Valve Springs Breaking - Valve Sticking. New valve springs are now being fitted with semi. closed ends. Depots have received these springs to replace broken ones. Depot sheets have been issued dealing with valves sticking. Item (26) Radiator Shutters Sticking and Filler Cap. There is nothing further to report. Item (27) Speedometer. X. 6051/2. We have had an improved speedometer from the A.T. makers. Archer and Dakin tested it out and although improvements had been made it was still considered further improvements could be attained. We are still waiting for the A.T. makers to remedy the faults pointed out to them. Item (28) Rear Axle Oil Leaks. There is nothing further to report. Item (29) Gearbox Oil Leaks. There is nothing further to report. Item (30) Tappets. There is nothing further to report. Item (31) H.T. Wire Tubes. There is nothing further to report. Item (32) Marmeto L.T. Wires. Phantom II & I. X 4473 W.W. do not agree to the turning round of the tube 180° and shortening the wires. They have sent a new design Loc. 2849. of tube with the wires arranged to prevent them becoming burnt. This arrangement will be brought into production on the next series of cars. For P.2. series a heat screen is being fitted. Item (33) Inter Fan Fabric Drive 20/25HP. With the result of Wright's investigation a shield is being experimentally tried out on the fabric drive to prevent oil getting on to the fabric. This scheme proving successful can be applied to existing cars. | ||
