Agenda for Discussion on Phantom III Position. --------------------------------------- Engines. Piston and Cylinder Liners. As a result of discussions with Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} it was tentatively agreed to take no action on design modifications pending the results of investigations by MX{John H Maddocks - Chief Proving Officer} on cylinder liners and cylinder liner rubbers. It was agreed to use no more cylinder liner rubbers to the old specifications. By.{R.W. Bailey - Chief Engineer} has been asked to instruct rubbers to the latest specification and D.I.Y.10. Oil Temperature Regulators As a result of a discussion with Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} a design modification will be issued incorporating corrugated side and end plates of the same gauge as the Buick, and reverting to the original type of tubes. As a separate experimental consideration should be given to the possibility of using a reversed type of serck cooler. Hydraulic Valve Gear. One of the failures in France was due to stoppage of metering plugs by particles of felt from the Tecalemit filter. A design has been issued for a gauze filter to replace the present Tecalemit type. The metering plugs are at present very inaccessible and the Design are looking into the possibility of altering the position of these to enable them to be removed without first having to remove the rocker shafts. Another trouble appears to be lack of oil feed to the plungers. Nos. 1 and 12 gave no trouble, Nos. 5 and 6 were slightly short of oil, and the intermediate plungers were the chief offenders. It is proposed to issue modifications to overcome this by altering the feed holes and providing a double feed, one to the plungers and one to the rocker shafts. It may be possible to delete some of the feed holes on the rocker shafts which will improve the oil feed to the plungers. | ||
