KS805 K872 18-GIV - 10,000 MILE TEST IN FRANCE. We have the following report from Hancock this morning :- "Re. Knock from Torque Reaction Damper. This was so persistent this morning that we dismantled the damper at noon and located the knock. It was due to insufficient clearance for the outer plates. These had been fouling the wiring tube. This was taken up both with the D.O. and our own fitters before we came out and they assured me that sufficient clearance had been given. We find, however, as stated above, that the clear-ance is not sufficient. This feature has always been a close job on the 25 HP. and it is absolutely necessary that more attention will have to be given to the clearance." Hancock also reports that the flinger on the clutch is not efficient because even when he reduces the automatic lubrication to the clutch spigot by means of a felt pad in the hole he still gets oil on the clutch plates. We think it is important that we should get this flinger right because though we have deleted the clutch spigot lubrication we still have to provide for the chauffeur who puts a syringe full of oil in his clutch shaft. We shall, therefore, be happy to test any modification you can suggest. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
