File 1263 Dixon PHANTOM 111 CHASSIS - PETROL PUMPS. In order to clear up the position in regard to the introduction of the new high pressure pumps on both the double and single unit type, it is essential that I should pass round the following information :- (a). At present we are still fitting the first proposal for three pumps viz. a double pump on the dash and a single pump on the dash, using the switch as modified by slotting between the Bakelite and the metal sections. This came on at the 76th chassis in 'C' series. (b). Following the above, when the new high pressure pump in the frame is available, which will not materialise for approximately 3/4 weeks, the combination will be double high pressure pump in the frame, the present single pump in its present position on the dash, using again the same switch as in (a). (c). When the Experimental Department are able to clear the new single high pressure pump, which will be fitted on the lower portion of the dash, then the combination will be :- (1). Double high pressure pump in the frame. (2). Single high pressure pump on the lower portion of the dash with new piping. (3). The present type of switch as in (a). I cannot at this moment define when the improved switch will be available, but following the above combination there should be a final position, with the double high pressure pump in the frame, the single high pressure pump at the lower portion of the dash, and the RR. switch. This would enable us to test each unit of the double pump separately, as well as the single pump. 134 BY.{R.W. Bailey - Chief Engineer} | ||
