The engine of the excavator needs to change the oil on time.   

  Excavators often work in a variety of harsh conditions, may also appear in the rush deadlines, work overload, so we should maintenance, ground maintenance, in this critical period will not drop the ball. For the excavator engine, more attention should be paid to maintenance, and the oil should be replaced on time.

One, the reason that the engine of the excavator should change the oil on time.

1, the oil is in a shelf life, and the oil performance will be reduced for a long time, which leads to the accelerated wear of the mechanical wear parts.

2. The physical and chemical properties of the engine oil are changed at high temperature in the engine, and the mechanical properties will be changed.

3, the engine running time is long, the oil impurities will increase, which will increase the wear speed of the mechanical parts.

Two. What should we pay attention to to replace the oil?

1, when the oil is replaced, the oil filter must be replaced at the same time. We must not be able to save money and save money and ignore the oil filter core. Why is that?

Because the dirt in the old machine filter will destroy the quality of the new oil, thus reducing the service life of the new oil.

2, in the fall you must remember to replace the winter oil, and in the spring must change the summer oil, unless your oil is the four seasons general oil.

Because the oil is slightly thinner in winter, in the summer, the oil will be thinner in winter, which is not conducive to the formation of oil film, and will also exacerbate the wear and tear of mechanical components.

In summer, the oil will be thicker after winter, which will not be conducive to the flow of oil. It will cause too much carbon accumulation in engine block, which will aggravate the wear and tear of mechanical parts.

Replace the oil on time is very important, if not timely replacement will accelerate wear parts, affect the service life, and even lead to machine overhaul, more serious is in the process of working if sudden problems will lead to accidents of scuffing of cylinder bore and so on, it is very important to the regular inspection and timely replacement of machine oil.
