To extend the life of a tractor engine, you must master several important aspects:

First, run-in. Do a good job of running the engine after the new machine or overhaul. According to the manufacturer's technical requirements and commissioning specifications carefully do a good run-in trial run, through testing and adjustment. In this way, a relatively smooth and hard bearing surface and the most suitable fitting clearance are provided, which provide good basic conditions for carrying load and prolonging the service life of the mating parts. After commissioning, the necessary technical maintenance should also be considered depending on the state of the machinery.

Second, qualified use of qualified oil and water. The fuel and lubricating oil used in tractors and engines must meet the quality standards set by the state, and the appropriate oil brand number should be selected according to the season, area, and engine speed range; cooling water should use soft water with low calcium and magnesium mineral content. . The easiest way to soften hard water is to boil the hard water and precipitate it. General production practice. Every 1000 hours of engine operation, the scale of the cooling system must be flushed to improve the engine's thermal performance.

Third, the normal guarantee of a normal water tank and oil pressure. Cooling water temperature is generally 70 °C ~ 90 °C, normal water temperature should be maintained between 80 °C ~ 90 °C for the appropriate. The water temperature is too low, it is difficult to start, the fuel cannot be fully burned, the engine power is reduced, and the amount of coke is increased; the water temperature is too high, some parts are prone to expansion and deformation, and even the accidents such as cylinder piston jamming and burning of tiles are caused, and the lubricant is also changed. Diluted, bearing film strength is low, wear is accelerated, but also may reduce the fresh air aeration. The engine power drops. To ensure that the normal oil pressure, that is guaranteed at 2 ~ 3kgf/cm2. If the oil pressure is too high, it can easily leak oil and cause poor lubrication. If the oil pressure is too low, it indicates that the oil supply is insufficient, lubrication is not reliable, wear is accelerated, and even a tile burning accident may occur. When it is found that the water temperature and the oil pressure are abnormal, they should be promptly eliminated according to the relevant reasons.

Fourth, the correct operation. To operate the tractor and the engine correctly, do not overload or over-rotate for a long time. Do not bang the throttle. Start steadily, turn slowly at low speed, and avoid sharp turns and sudden braking.

Fifth, we must seriously implement the maintenance rules. According to the prevention-oriented spirit and the principle of prevention-responsive-to-governance and conservation-by-repair, the tractor and engine are regularly cleaned, tightened, inspected, lubricated, adjusted, and replaced with certain oxidation-damaged plastics, plastic parts, and wear overruns. The parts, technical maintenance on time, according to requirements, to ensure that all parts function normal, effective and reliable.
