| DEPOT SHEET NO.HM.{Capt. W. Hallam - Head Repairs}25. LUBRICATION OF CLUTCH - PHANTOM. Extended experience with the Rolls-Royce Phantom single plate clutch has shewn that improved smoothness of operation can be maintained without affecting the drive by occasional lubrication. The best form of lubricant is a 50% mixture of engine oil and paraffin, which should be applied as follows :- (1) Remove the small inspection cover, secured by two studs, situated on top of the clutch casing. (2) On turning the engine by means of the starting handle, four small holes at 90° will be observed in the rim of the flywheel. Inject, with a syringe (if available) or otherwise with the Lucas oiler No.40, about an eggcupful of the lubricant into the four holes, (one quarter of the amount into each hole) whilst the clutch pedal is depressed. (3) Start engine and operate the clutch repeatedly, taking care to slip it a reasonable amount in order to distribute the lubricant thoroughly over the surfaces. (4) Inject a second eggcupful of lubricant as before and repeat the former process of operating and slipping the clutch. Any excess of lubricant will get away through a hole in the clutch casing. (5) Replace the inspection cover. If it is considered at any time that the clutch is operating at all unevenly, the clutch lever adjustment should first of all be verified, as described on pages 109 and 110 of the Instruction Book, and only if found necessary after this has been done, should this process of lubrication be carried out. | ||
