DRY SUMP SYSTEM

CORRECT LUBiRICATION. I j Many riders, either from ignorance of the salient facts or of the contempt brad of familiarity, fail to avail themselves of the advantages that correct lubrication ofr'ers in the matter of lessened depreciation economy in fuel and oil consumption, and the decreased amount of the annual repair bill. ! Man ybwners of machines which are fitted with dry sump lubrication fail j to recognise the responsibility which ; the advantages of this system bring. j This responsibility is to keep the sys- j tem clean and clear. If any of the oilway and pipes become clogged serious . damage may result to the engine. 1 All oil becomes contaminated with use. Foreign matters accumulated, sludge forms — and these must be periodically removed. Sludge is the re- j sult of oxidation of the oil; that is, a chemical change due to the contact of hot air with the hot oil during engine j operation. Sludge will precipdtate or settle out while it is circulating and lod«-~ in the j oilways. Thus it is possible that a compiete blockage may be caused. The only way to prevent trouble j from these sources is to drain the i who?e system (including the tank | and sump) at intervals, never driving I more than 2000 miles without doing J so. ! Between draining periods the oil should always be kept at the "full" mark, as this ensures that the whole body of the oil in eirculation is kept at a lower temperature, and the tendency to oxidation is lesesned. After refilling a tank that has become dry, an "airlock" sometimes occurs. If the pump does not deliver oil after the engine has been running for a minute of two, slaclcen the suction pipe union on the pump and wait until the oil begins to flow out freely. Then tighten up again and compiete eirculation should follow. Another point that has a profound bearing on the wear of your engine. Use a lubricant that has been proved to always stand up to the hardest ricting conditions, and use a spirit that will give split-second starting. By doing so you will avoid many troubles that are likely to occur with an engine that is given a "diet" of any old thing that comes along.
