When the parts of the excavator fail, it will affect the excavator’s inability to work smoothly, so it is necessary to replace the parts of the excavator in time, but because the progress of the project is often in a hurry, there may not be enough time. Let everyone choose the excavator accessories carefully, so some friends just take one and replace it when choosing accessories. It is necessary to know that if the excavator accessories are not matched, it will cause serious damage to the excavator.
the Model Does Not Match
In the maintenance process, the phenomenon of substituting or misusing excavator parts is still very common. Emergency substitution of some parts is feasible, but long-term use is harmful and unhelpful, which has a great impact on the safety and technical performance of the excavator. If the parts suitable for Yanmar gc950 engine are applied to the parts suitable for Komatsu 4d94le engine, there will be serious adverse consequences.
Some maintenance personnel has little understanding of the structure and principle of the excavator, so there is a wrong idea that even if the model of the excavator does not match, as long as it can be installed, they have not considered the serious consequences of such an approach. There are examples.
The hydraulic pump of the excavator accessories has serious internal leakage, and the excavator cannot work normally. Replace the new pump. After the new pump is installed, the car stalls, the speed of the excavator is slow, and it is powerless. Due to the different engine power required by the two pumps, the engine was underpowered after the new pump was installed. The hydraulic pump is a load component for the engine. The engine and hydraulic pump have been matched in power before leaving the factory, so changing the hydraulic configuration of the excavator will cause problems.
Once again, I remind everyone that when repairing construction machinery, you should try to use the original model of excavator accessories, and you cannot use other types of accessories instead, let alone make mistakes.
The Treatment Method of “change the Soup Without Changing the Medicine”
The engineering side is pressing hard, and the construction cannot be delayed. In the face of urgent projects, many bosses will rush to urge the maintenance masters, replacing “maintenance” with “emergency”, and the phenomenon of “treating the symptoms but not the root cause” is very common in the circle.
The air conditioning refrigeration effect of excavator accessories is poor, and the air conditioning compressor intermittently pulls in. After seeing it, the customer does not directly deal with the cause of the failure of the compressor but artificially fixes the compressor clutch together. As a result, the air-conditioning compressor will work for a long time, and the compressor will be damaged within a few days, and the correct way to deal with it is to check the reason why the compressor of the excavator accessories does not pull in.
The replacement or misuse of excavator accessories is common, regardless of the type of accessories. During repairs, replacement or misuse of spare parts is still common. Emergency replacement of some spare parts is feasible, but there is no benefit in long-term use, affecting the safety and technical function of the machinery.

Some excavator maintenance personnel know little about the mechanical structure and principle, and many types of spare parts do not match, but they think that as long as they can be installed, they will not think about whether the actual function of the machine can be achieved. For example, a 4120F diesel engine should use a 350-watt generator, and a 500-watt generator wastes electricity; the ZL50 loader uses a QD274 starter, while the QD50 starter is difficult to start due to insufficient power; valves and rocker’s arms are not common, but often mixed Phenomenon. This makes starting and reducing power difficult. It has even become a serious machine damage problem. Therefore, it is a serious mistake to apply the parts suitable for the Yanmar gc950 engine to the parts suitable for the Komatsu 4d94le engine, and it will have bad consequences.

The 6135ZD turbocharged diesel engine starts smoothly after replacing the original piston (turbocharged type) due to misuse of the non-turbocharged diesel piston. Therefore, when repairing the excavator, you should try to use the original accessories, do not use other types of accessories, and do not misuse them.
TL180 bulldozer, the air filter core is damaged, the operator does not replace it immediately, and the mechanical use time is short. This shortcoming is caused by neglecting the maintenance of “small parts” and should be used as a warning.
