| The following points arising from Customers Complaints and Service Depot criticisms, have been discussed by BY.{R.W. Bailey - Chief Engineer} Mx.{John H Maddocks - Chief Proving Officer} and GWH.{George W. Hancock - Head Chateauroux} PHANTOM III CHASSIS. 1. Overoiling on 'D' series cars when used in London traffic conditions. Instructions for dealing with these cases when they arise are being issued forthwith. 2. Wear of chromium faced tappets. This has not been entirely cleared up by deletion of hydraulic mechanism, and the matter is having further consideration. [Handwritten note: Wraith type belts deader adoptable & repairs] 3. Servo Squeaks. These are fairly frequent as a result of continuous light use of brakes in London traffic. A temporary cure is effected by dismantling servo and removing glaze from friction discs. A few sets of R.A.D.13 material have been handed to GWH.{George W. Hancock - Head Chateauroux} for trial, this is known to be less prone to squeaking. 4. Hand brake adjustment. Difficulty is experienced in carrying out adjustment owing to rusting of the serrated bush, which necessitates considerable dismantling of the brake mechanism to free same. Instructions were issued on the 1.7.36 for all parts in connection with the adjustment to be cadmium plated. There are about 40 of the first P.III. which were not done. We should like information as to whether trouble is experienced with cars fitted with cadmium plated parts. [Handwritten note: non cadmium] 5. Rattles in steering column controls. [Handwritten note: NO] GWH.{George W. Hancock - Head Chateauroux} will investigate whether these are a result of hammering of side steering tube contact pieces, as experienced in development of Wraith. Design Dept. looking into the possibility of maintaining felt bush pressure by means of a fluted spring, also providing some method of keeping the felt continuously lubricated. Cont'd..... | ||
