How to maintain excavator parts

1. Oil is only added but not changed

Engine oil is essential in the use of diesel engines, mainly for lubrication, cooling, cleaning and other functions.

Therefore, many drivers will pay attention to check the amount of lubricating oil and add it according to the standard, but they ignore the inspection of the quality of the lubricating oil and the replacement of the deteriorated oil, resulting in some excavator parts of the engine are always in poor lubrication. Operating in the environment, thereby accelerating the wear and tear of various parts.

Under normal circumstances, the loss of engine oil is not large, but it is easily polluted, thus losing the role of protecting the diesel engine. During the operation of the diesel engine, many dirt (soot, carbon deposits and fouling generated by incomplete combustion of fuel) will enter the engine oil.

For new or overhauled excavator parts, there will be more impurities after trial operation. If you just add them without changing them and rush to put them into use, it is easy to cause accidents such as tile burning and shaft holding.

In addition, even if the engine oil is changed, some drivers will not thoroughly clean the oil passage due to lack of maintenance experience or to save trouble, so that mechanical impurities still remain in the oil pan and oil passage.

2. Misuse of butter

Grease the cylinder head gasket. Butter is a grease commonly used in the repair of construction machinery, which can play the role of lubrication and sealing.

Therefore, some repairmen will put a layer of butter on the cylinder gasket when installing the cylinder gasket, thinking that this can increase the sealing of the diesel engine. As everyone knows, doing so will affect the working performance of the diesel engine.

The cylinder gasket is the most important excavator accessory between the cylinder block and the cylinder head of a diesel engine. It can not only seal the high-temperature and high-pressure gas generated in the cylinder, but also seal the cooling water and lubricating oil in the cylinder head and cylinder body, so When disassembling the cylinder gasket, pay special attention to its sealing quality.

If butter is applied to the cylinder gasket during installation, when the cylinder head bolts are tightened, part of the butter will be squeezed into the cylinder water channel and oil passage, and the butter remaining between the cylinder gasket will flow due to the high temperature when the cylinder is working. The other part remains on the joint surface between the cylinder block and the cylinder head, so that there is a gap between the cylinder gasket, the cylinder head and the plane of the body, and the high-temperature and high-pressure gas can easily impact the cylinder gasket from here, destroying the cylinder gasket and causing leakage. gas.

In addition, when the butter is at high temperature for a long time, it will also produce carbon deposits, which will cause premature aging and deterioration of the cylinder pad. Therefore, do not apply butter when installing the cylinder head gasket.
