| Minute No.6. Cont'd.{John DeLooze - Company Secretary} -3- Hyl/R.29.8.33. Wor.{Arthur Wormald - General Works Manager} instructed that 15 sets of pistons should be immediately produced to E's latest instructions with bearing surface on the lands between the rings; these improved pistons are to be fitted to the 15 chassis when they are returned to the Works for final test. 7. Engine Gears. Hs.{Lord Ernest Hives - Chair} reported that the engine which is fitted with a fabroil camshaft gears has up to the present proved to be satisfactory. Hs.{Lord Ernest Hives - Chair} asked for a decision to be made as to the type of camshaft gear which should be fitted to the next 10,000 miles car. After some discussion it was decided that the only reasonable thing to do was to fit standard gears which we know to be reliable and to try out fabroil gears on some of the 15 chassis as and when such gears become available. These 15 chassis will be kept under our observation. 8. Oil Temperatures. Hs.{Lord Ernest Hives - Chair} mentioned that during the recent running in France the operating oil temperature had been dangerously high owing to the excessively hot weather; the question was not further discussed. 9. A Second 10,000 mile car. Hs.{Lord Ernest Hives - Chair} suggested that another car should be prepared for 10,000 miles test to follow up the car which is at present running. It was therefore decided to re-build one of the existing Experimental Cars and that this re-built car should be fitted with further developments and modifications. 10. Whistling Noise from engine. Wor.{Arthur Wormald - General Works Manager} here referred to a report from EP.{G. Eric Platford - Chief Quality Engineer} who complained of a whistling noise between 2,800 and 4,000 revs. E.{Mr Elliott - Chief Engineer} explained that this is caused by the starter gear ring teeth being close to the casing. Since the original design the ring has been made larger. E.{Mr Elliott - Chief Engineer} will arrange for the clearance between the gear case and ring to be increased, and this should remove the cause of the noise. 11. Horn Button. Wor.{Arthur Wormald - General Works Manager} said that the horn button is in a recess and it is difficult to make sure that contact is made in emergency. It is suggested that the horn button should project somewhat in order to make more certain that contact is made. Hs.{Lord Ernest Hives - Chair} stated that since the original design the horn button has been raised and now projects about .150". | ||
