A little while back Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} raised a query as to whether the above pump stroke capacity was sufficient to lubricate the whole of a Ph.II chassis, the respective capacities being, Luvax 16 c.c's, R.R. Pump 27 c.c's. There are 42 meter valves on the Bentley being fed by the Luvax Pump, this giving an ample supply. On the Ph.II there are 43 meter valves, the difference in requirements of the two chassis being negligible, and we do not see that it is necessary to go to the expense of Pump alteration to raise the capacity unnecessarily. In the event of the Pump capacity being increased it will mean the following modifications :- (1) Increased length of piston rod and cylinder. (2) Modify the upper end of the pedal to suit increased con. rod. (3) The slot in the pedal bracket will also require modification. The Luvax Company have quoted us a price for these alterations. There would be an extra charge of 1/6d. in the first 150 pumps, after which the price would be reduced to 9d. per pump extra. Hs{Lord Ernest Hives - Chair}/Bwg.{J. C. Bowring} | ||
