ITlMllMMIIIIIMtlMMIHIIIMIIMIMIIMMIIMMIMMIMIMHMIMniHtMMIIIIMIIMIIMItllMIMMIIMMIMMtlMIMPIIIMIHniMIMMMtIIIMIIMlltlUt AUTOMOBILE NEWS You Will Get Here . fnu(n,MII,(,tl(HOIIIIIIII"HIMIItlttIIIIMIIIIMMmIMtMIIMMMMM THE COCONINO SUN 'i A I' AUTOMOBILE LUBRICATION THE HOW, WHEIE ANl) WHY OF THE OIL AND GREASE; OIL IS THE PROPER STUFF FOR YOUR TRANSMISSION; DIFFERENT PARTS NEED DIFFERENT OILS In spite of the insistence of motor car manufactuiers anil service men on the vital importance of lubrication as it affects the life of the vehicle, it is doubtful if the average car gets all that it really needs in this connection. Nor is the reason far to seek; we have upward of a million new car owners in this country every year, and they all must learn the lessons that the pie ccding motoring generation has come to take as a matter of course. Fur ther, we aic learning all the time in every branch of the automobile indus try and the science of lubrication is constantly developing. So it is that the wise motorist reads all that he can' find in regard to lubrication, and here arc a few suggestions that may help him: Should Use Oil To begin with, let us addiess a few words to car owners who are sun us ing grease in the transmission. Oil is the proper lubricant for the gearsct. The gear teeth cut a path through the heavier lubricant and proceed to re volve in thin air to their great detri ment. In addition, grease has the unfortunate characteristic of carrying dirt and foreign matter of any kind into the gears or whoicver else it may be used. In cold weather grease is simply impossible. After the gearsct has been in operation for a short time the grease becomes packed against the walls of the housing and the gears themselves get no lubrication what ever. So make this your first lubri cation law: "Use transmission oil of the proper grade in this part of the mechanism." Grease Cups Not many years ago grease cups were used in all parts of the mecha nism for lubricating bearings, etc. Now grease is not the best lubricant for this location, because it has a characteristic of getting hard in the cup, so that the latter can not be properly turned down, hence the part does not get adequate lubrication. It is for this reason that more and more cars every year are being fitted with oil cups in many locations though the familiar grease receptacle still persists on many parts of even the best cars. The owner who really un derstands his car-knows without being told that oil is better than grease, but perhaps he can substitute oil cups for the grease variety. Within the past year or so a num ber of very ingenious oil cups have been placed on the market, embody ing systems of gradual feed whereby the oil is permitted to leak out gradu ally instead of running away in a sin gle day as used to be the case. That was always the trouble with oil cups, you had to keep filling them up each day. Some of these new cups have constructed passages which permit of only a slow flow of oil, Vhile others have what are known as wick feeds, wherein a wick picks up the oil from the cup and allows it to reach the part to be lubricated gradually. Some of these cups need replenish ment only once or twice in a running season. Another advantage of the wick feed is that, since it operates by capillary attraction, it does not carry dirt or foreign matter to the bearing surface, even if it is present in the cup. As a matter of fact the wick feed cup is probably the nearest thing to having the parts running in oil. Naturally the different parts of the mechanism require different grades of lubricants, or better, say oils. For the gearset, differential and rear axle a heavy .oil is the proper lubricant. THINGS TO WORRY ABOUT To avoid accidents when cranking the car by hand place the thumb close against the index finger and take the handle between the four fingers and the palm of the hand. In this way the hand opens readily if a back kick occurs. Also always crank up, never down. In some instances the stem of the water pump has become so worn, usu ally in annular grooves, that the pump can not be packed to make it tight. When this happens the only thing to do is to lemove the single, true it up on the lathe and have a new bushinj. fitted to it. After this, if hempsoaked in tallow, wicking or some other good packing is used, the joint can be made tight. In dealing with a small screw that refused to yield to the blandishments of a screwdriver, try holding a hot soldering iron against the head. This will often do the trick by loosening the rust between the metal surfaces. Heating a screw head as mentioned and then soaking it with kerosene will bring out practically any screw. GOOD HORN IS A GREAT PROTECTION A horn on your car that can make a. sufficient volume of noise to be heard around the curve of a mountain road is one of the best forms of insurance against accident that you can cany for your summer vacation trip. Though you drive as carefully as you can, you can not always protect yourself against the driving of the other fellow unless you give him fair warning before you come to a curve. By the number of motorists who have recently had their cars equipped with more powerful horns it seems the ma jority of owners are coming to realize this. Ah accident on a mountain road is doubly serious because of the fact that it is usually a long distance to aid of any sort, and it is an extreme ly expensive matter to bring a dam aged car to a point where it can be repaired. MORE DONTS FOR THE AUTOMOBILE OWNER Other pa its of-the mechanism do bet ter on the ordinary cylinder oil. For the average car two grades of oil will practically take care of the entiic mechanism. It has always been customary to lu bricate universal joints by means of grease or graphite, simply because of the difficulty of keeping oil in the housing of the joint. The universals move with tremendous rapidity when the mechanism is in operation, and they need very efficient lubrication. Recently it has been found possible to lubricate the universal joints by the means of oil fed through wicks. In many cases this change in the lubrica tion of the universal would necessi tate redesign of the part, an expense that the manufactuier is loath to in cur. In some instances the car owner can have this change made on his own car, and it will ceitainjy be to the advantage of his vehicle's operation. Before we leave the subject of wick oiling it might be well to call atten tion to the economy of this method. The wick draws the oil from the cup slowly and distributes it evenly over the whole surface to be lubricated. There is no waste. A well-designed wick feed oil cup will need replenish ing only once or twice in a season." This question of lubrication is one that has engaged the attention of en gineers from the very beginning of the automobile industry. Some of our engineers have attempted the nega tive solution of the difficulty by dis pensing with grease and oil cups and substituting bushing made of wood or soft metal impregnated with graphite, which gives a sort of perpetual lubri cating characteristic to the part. For certain paits of the mechanism these oillcss and greaselcss bearings serve very -nicely. But where there is in tense movement this type of lubrica tion is scarcely up to the work de manded of it. At that, they are prob ably better than grease cups which the car owner has forgotten to turn down. It seems to be accepted in engineer ing circles that eventually we shall have a car with a central oil reservoir, from which practically all parts that need it will be supplied with lubricant. When that happy day arrives all the owners will have to do will be to fill up the central well at stated inter vals. When that time arrives, as long as the oil system is functioning prop erly wo shall have perfect lubrication, and haven't the engineers always told us that that means the everlasting car? In the meantime the car owner who wants his vehicle to last as long as possible can contribute to that end by substituting properly designed oil cups for the inefficient grease cups now so widely used. Don't underinflatc or overload tiies. These are the most common causes of tiie trouble. Avoid underinflation by testing the air pressure semi-weekly. Don't neglect cuts. Water and dirt get in and rot the fabric, often caus ing blowouts. Inspect your tires at least weekly for cuts and have them sealed promptly. Don't let your wheels run out of line. If your tires show undue wear, don't blame it to the tires, but find out the cause. Usually you will find your wheels are out of line, with the result that your tiies aie dragging. Don't stop or start suddenly. This strains your tires unnecessarily and causes rapid wean Don't run on a flat tire. Nothing ruins a tire more quickly. Better re move the tire and run in on the rim if necessary. Don't let gasoline, oil or grease re main on your tires. They all deterio rate rubber. Don't let the car rest on a deflated tire. Better remove the tire or jack up the wheel. Don't carry a spare tire for long time without using. Change over once in a while. A tire often deterio rates faster on the tire carrier than on the wheel. CLEANING THE CAR ! The body of the car should be thor ! oughly cleaned with castile soap and I water. Mud should not be rubbed off, i but rather should be washed off flow- I ! ing a gentle stream of water over the i spot, This floats the mud off, witli- out injury ui mu juiisiiuu suuucu.ji mud is permitted to remain on a neV j body until it dries hard it almost al t ways leaves a spot", consequently re j moval should be immediate. If spots of road oil get on the body they should .be removed by an application of salt butter, which loosens the oil, or by local application of kerosene. But be careful not to rub them too much. The top should not be cleaned with gasoline or similar liquids. Soap suds and water should be used inside and out. For the upholstery a little lin seed oil on a piece of cloth rubbed over it will work wonders. WATER IN CRANKCASE OIL Few motorists realize that a com paratively large quantity of water gradually accumulates in the crank case, mixing with the oil and forming an emulsion, which has impaired lu bricating qualities. The accumulation of water is more pronounced in win ter than in summer and is found to a greater extent as the number of cylinders increase. This brings out the importance of changing the oil every 1,000 miles, and for the best lubricating results every 500 miles, in which case the old oil may be run through a chamois skin to remove the water, after which it may be used again. CARBURETOR ILLS Harley-Davidson Motorcycle 2x ,5f sV l v y Ay For Sale By J. W. ROBINSON P. O. BOX 1083 DELION TIRES AND TUBES R Un X L D Northern Arizona Motor Company Flagstaff, Arizona In many cars water and dirt in the system cause almost endless trouble, which may very likely be attributed to the engine proper. Dirt will clog the minute crevice in the carburetor, caus ing numerous peculiar symptoms of trouble to appear. Many cars have no provision, except a metal strainer in the tank, for preventing the entrance of dirt into the fuel system. It is suggested that the owners of cars so equipped fit a trap in the gasoline line. All the larger manufacturers of carburetors have devices of this kind. A method of restoring a front axle which has been bent is to take two lengths of 4 b'y 4-inch joists just long enough to reach from the upper side of the axle outside each spring plate to a cross timber of the ceiling or roof of the garage. Then if a jack is placed beneath the axle at the bend enough pressure may be applied by means of it to force the axle back into shape. Owners of cars fitted with battery ignition systems sometimes go to un necessary trouble cleaning the spark plugs and the like because of misfir ing, when this is due simply to dirt or carbon on the track of the distributor head. If the track becomes sooted so that the spark jumps from one terminal to another, preignition is likely to result. The easiest way to test for such trouble is to substitute another distributor head of the same model and observe the effect upon the operation of the engine. o The tube should be rolled flat with soft cloth between the layers; a strip of cotton flannel rolled up with the tube is excellent. The roll should then be placed in a thick cloth bag with the stem protruding and the mouth of the bag can be tied around the stem. It is a good plan to put tal cum powder in the bag.
