| COPY. To Wor.{Arthur Wormald - General Works Manager} from Mx.{John H Maddocks - Chief Proving Officer} Mx{John H Maddocks - Chief Proving Officer}9/T25/5/25. re 'V' SERIES CHASSIS. Herewith my comments on points raised by EP.{G. Eric Platford - Chief Quality Engineer} on 'V' series chassis. 1. Instrument Board. This does not affect me. 2. Radiator Shutter Control Rod. This point I took in the early stages with BY.{R.W. Bailey - Chief Engineer} and Hs.{Lord Ernest Hives - Chair} I believe some improvement scheme is in hand which Hs.{Lord Ernest Hives - Chair} is trying on an Experimental Car. In the meantime we are making certain on Cars we are delivering, the ball end in question is as good a fit as is possible. 3. Fan. The bad vibration period complained of is caused by two factors - (1) Fans being out of balance. (2) Unsatisfactory belt. I have established that either of these factors, or a combination of the two is sufficient to set up the period complained of. We are arranging as you know to have every fan specially tested for static and rotation balance, before the cars are despatched. We are making the best of the supply of the Whittle Belts, and have arranged with Hs.{Lord Ernest Hives - Chair} to try out some Brammer Belts which he is recommending. 4. Falling off in power. I have had no experience of this complaint. The tendency is for cars to improve rather than deteriorate during the course of testing. 5. Tappet Mechanism. We are always up against the tendency of quiet tappet and valve mechanism. Invariably on a quiet engine there is one tappet which is noisier than the rest. I am discouraging the tendency to reduce the tappet clearance to a dangerous point in order to obtain quietness. 6. Engine gear quietness. I feel that you know as much about this as I do. 7. Noisy Dynamos. I am not at all prepared to agree up to the present that this noise is from the Dynamo. I feel that the noise comes from the Engine gears, and is due from the extra load from the dynamo when on charge. Contd. | ||
