Why should the excavator oil be changed on time?

1. Shelf life:


Over time, performance will be reduced, leading to accelerated wear of mechanical parts.


2. Performance changes:


The physical and chemical properties of engine oil will change after high temperature operation in the engine, and its mechanical properties will also change accordingly.


3. Wear:


If the engine runs for a long time, the impurities in the oil will increase, which will increase the wear rate of mechanical parts.

What will happen if the oil is not changed?


1. The oil pressure is too low:


Failure to change the engine oil on time will cause the oil pressure to be too low. The most direct consequence of too low oil pressure is that it will cause semi-dry friction or dry friction between various mating parts, and the engine will have obvious abnormal noise, and in severe cases, it will cause tile burning.


2. The oil pressure is too high:


Failure to change the oil on time will also cause the problem of excessive oil pressure. Excessive oil pressure will cause premature damage to the gasoline filter, carbon deposits in the engine cylinder, and other failures, and will also reduce the life of the engine.


3. Too much sludge:


Failure to change the engine oil on time will cause excessive sludge problems. Sludge is generally due to the high-pressure unburned gas, acid, moisture, sulfur and nitrogen oxides in the combustion chamber entering the crankcase oil through the gap between the piston ring and the cylinder wall, and is mixed with the metal powder produced by the wear of the parts , Slowly accumulate, and then sludge is formed.


4. Parts wear:


If the oil is not changed on time, the most serious consequence is the wear and tear of various mechanical parts of the engine, such as pistons and cylinders. Once there is a problem with the piston and cylinder, the machine needs to be overhauled, and overhaul is something that every owner does not want to see.
