[Handwritten Signature, Struck through in red]: WYMN PHANTOM 111 - LUBRICATION OF EXHAUST SUPPORT BEARINGS. Please receive herewith E.CD.592 Oil Feed to Exhaust System Suspension Links. Phantom lll. The object of this design is to eliminate the risk of squeaks at the spherical supports, which have been the subject of complaints from Depots. We have not made any provision for preventing surplus oil from dropping on to the exhaust silencer, as Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} does not think this will cause any trouble, but should there be any, shields can be devised, but we hope to avoid them. All the fittings used for the oil supply are standard Luvax Bijur pieces, and it will be necessary to arrange for the additional pipes to be coupled into the existing lubrication system. It will be necessary to clear the floorboards away slightly, to make room for the oil supply pipe to the silencer support, this will affect the coachbuilding drawing. Should the oil finding its way down between the surfaces not provide sufficient lubrication to the lower joint, we have shewn a system of holes and grooves which can be tried in that event. Will you please instruct the necessary parts for this design to be tried experimentally. DA.{Bernard Day - Chassis Design} | ||
