Lubricating oil is usually called oil. The standard for adding oil to the oil sump of the tractor is that some engine oils have three marks on the oil ruler. Generally, it is appropriate to reach the intermediate mark. Some engine oil marks have only two marks on the ruler. The common oil surface should be between the two lines, and the following “Five taboos†should be observed when adding the oil. If you do not add in time before the engine starts, if the engine oil fails to meet the standard, add it in time. Otherwise, the oil level in the oil pan is too low, resulting in high oil temperature and poor lubrication. What's more serious is that the oil level on the oil pan is lower than the lower mark. When the tractor is on the uphill, over the ridge, or in sudden brake braking, the oil net will be exposed on the oil surface, so that the oil pump can suck in air and cannot be supplied with oil, causing burning. Severe accidents such as tile, the consequences can be disastrous. Second, avoid the new and old oil mixed use of old and new oil will accelerate the oxidation of new oil, reduce the effect of the use of new oil, in the engine once enough to add enough new oil, can use more than 500 hours. Instead, half of the new engine oil was blended with half of the old engine oil and used for only 200 hours. After the deterioration of the oil lubrication performance, the internal parts of the engine can easily cause serious wear and black smoke. 3 bogey to add too much oil in the engine oil sump over the engine, more than on the engraved line, improve the engine speed is easy to break into the combustion chamber, so that the exhaust pipe spray oil, take the blue smoke. This will not only increase the consumption of oil, but also the oil that is not completely burned will produce a large amount of carbon on the top of the piston and the valve seat, and even cause the piston ring to be seized or damaged and accelerate the wear of mechanical parts. 4. Avoid using the same oil in both summer and winter. Usually the oil is thicker as the oil number increases, and the oil is thinner as the oil number increases. In northern China, high-speed diesel engines can use No. 8 engine oil in winter and No. 11 engine oil in summer. In southern China, high-speed diesel engines can use No. 11 engine oil in winter and No. 14 engine oil in summer. Five bogey when adding oil does not pay attention to cleanliness I often see some drivers, when adding the oil, do not cover the fuel port covered with dust before cleaning, in order to save time open the filler cap on the refueling, so that the most likely to make dust and machinery Impurities are artificially brought into the oil pan, which will inevitably wear out the engine in the early days, especially in the severe north of the wind, and the consequences are even more serious.
