The Ford Lubricating System
| How does the Ford Lubricating System differ from others? | Answer No. 98 |
It is simplified—and there are fewer places to oil. Practically all of the parts of the engine and transmission are oiled by the Ford splash system, from the one big oil reservoir in the crank case. Cut No. 18 shows the principal points of lubrication, and specifies when replenishment should be made, according to mileage. This chart should be studied carefully and often. It is a good plan to frequently supply all oil cups with the same oil used in the engine (any good light grade lubricating oil will answer) and the dope cups with good grease. Be sure to see that the commutator is kept freely supplied with oil at all times.
| Which is the best way to fill the "Dope" Cups? | Answer No. 99 |
When it is advisable to fill dope cup covers screw them down, refill with grease and repeat the operation two of three times. Always open oil cups by turning to right, as this keeps tightening rather than loosening them. Occasionally remove front wheels and supply dope to wearing surface. A drop of oil now and then in crank-handle bearing is necessary, also on fan belt pulleys and shaft. The sales, drive shaft and universal joint are well supplied with lubricant when the car leaves the factory, but it is well to examine and oil them frequently.
| What kind of Oil should be used? | Answer No. 100 |
We recommend only medium light high-grade gas engine oil for use in the Model T motor. A medium light grade of oil is preferred as it will naturally reach the bearings with greater ease and consequently less heat will develop on account of friction. The oil should, however, have sufficient body so that the pressure between the two bearing surfaces will not force the oil out and allow the metal to come in actual contact. Heavy and inferior oils have a tendency to carbonise quickly, also "gum up" the piston rings, valve stems and bearings. In cold weather a light grade of oil having a low cold test is absolutely essential for the proper lubrication of the car. Graphite should not be used as a lubricant in the engine or the transmission as it will have a tendency to short-circuit the magneto.
| How often should Oil be drained from Crank Case? | Answer No. 101 |
It is advisable to clean out the crank case by draining off the dirty oil when the new car has been driven three hundred and fifty miles; thereafter it will only be necessary to repeat this operation about every seven hundred and fifty miles. Remove the plug underneath the flywheel casing and drain off the oil. Replace the plug and pour in a gallon of keresone oil through the breather pipe. Turn the engine over fifteen or twenty times so that the splash from the keresene oil will thoroughly cleanse the engine. Remove crank case plug and drain off kerosene oil. It is of vital importance that all the kerosene be removed from the depressions in the crank case. To do this put about a quart of lubricating oil into the motor and turn the engine over several times, then remove crank case plug and drain off the flushing oil, then replace plug and refill with fresh oil (See Answer No. 3)
| How often should Commutator be oiled? | Answer No. 102 |
Keeping the commutator well oiled is a matter of far greater importance than many drivers believe, and is necessary in order to have a smooth operating engine.
