Axle Pinion. ------------- With reference to the failure of the axle pinion, Design department are to examine the Experimental Department's scheme drawing of a modified outboard bearing, which, as described, appears to be advantageous. Lagged Intermediate Silencer. ---------------------------- It was agreed that this can come on production in mild steel. The type of lagging to be used is inthe form of asbestos rope with a protective covering. The question of doing away with the exhaust flanges immediately behind the front expansion box was raised. This is a modification which production are continually asking for. The Experimental Department agreed to investigate this. Geared Starter Motor. --------------------- It was agreed that this should come on production. Tests both on the road and in the freezing chamber had shown that this was a very definite advantage. With regard to the complaints of a whirring noise due to the starter motor speeding up when the pinion is thrown out of mesh with the flywheel gear ring. It was not quite clear what was the actual cause of this. Experimental Department are carrying out investigations to clear this matter up. In any case it was not thought that it was a serious drawback. Small Dynamo. ------------- This has proved satisfactory on the French test car and also on various other cars and it is a desirable feature for standardisation because of its reduced weight and improved appearance. It is the same machine as is used on the 20/25 HP car but on the Bentley it is running at a slower speed and in consequence it cuts in at a higher road speed, approximately at 18 miles an hour.
