BY/NW.{N. Walker - Patents} From Hs{Lord Ernest Hives - Chair}/Tsn. Hs{Lord Ernest Hives - Chair}/Tsn. 2/W.1.1.30. INSTRUCTION BOOK - LUBRICATION OF AXLES: It is found that if the present Instruction Book remarks be followed literally, then insufficient oil will be supplied when oiling axles. If the gun be put on the nipple and then just screwed up solid once without using much force, only about half a teaspoonful of oil will penetrate the thick felt filter in the nipple. It will certainly not get as far as the air chambers inside the pivots. We recommend that a page be prepared and inserted in all Instruction Books, both 20 HP and Phantom II including those already issued, reading roughly as follows:- LUBRICATION OF AXLES WITH GUN. It is found advisable to give the oil somewhat more chance of penetrating the felt filters and long pipes on the axles than as recommended hitherto in the text. To begin with, the oil gun should be kept filled with engine oil during both summer and winter, as this is adequate for the axles and other oil-gun points. Gear oil should only be used in the summer in the dash-board tank, which is subject to undue heat. The oil gun should be applied to the axles and screwed in until a resistance is felt to further turning. This denotes that oil is about to enter the felt filter on the axle. The handle should now be turned one complete turn or until the piston has been screwed in a quarter of an inch. This is sufficient for each axle, and should be repeated at the recommended intervals of every 5000 miles, or once a week. The operation of charging the axles may occupy a minute or so, and may require a little force but a few pauses will enable the oil to get through the pipes a little and relieve the pressure.
