Liugong loader is an important equipment in the field of construction machinery, and its efficient and stable operation is inseparable from the right gear oil. Gear oil plays multiple roles in the work of a loader, such as lubrication, cooling, cleaning and rust prevention, so changing gear oil regularly is key to maintaining good loader performance. So, how often should the gear oil of Liugong loaders be changed? It mainly depends on the working environment and work intensity of the loader. Generally speaking, if the loader is working in a harsh environment, such as high temperature, high humidity, high load, etc., the gear oil replacement cycle should be shortened accordingly. On the contrary, if the loader works in a relatively good environment, the gear oil replacement interval can be appropriately extended. Specifically, it is recommended that the owner refer to the instruction manual of the Liugong loader, which will have suggestions for the gear oil replacement cycle for this type of loader. At the same time, the owner can also communicate with professional maintenance personnel according to their own experience and the actual situation of the loader to determine the appropriate gear oil replacement cycle. In addition, when changing the gear oil, the owner should choose a high-quality gear oil that meets the requirements of Liugong loaders to avoid damage to the loader caused by the use of inferior gear oil. When changing the gear oil, you should also pay attention to the cleanliness during the replacement process to avoid impurities entering the gearbox. In short, regular replacement of Liugong loader gear oil is an important guarantee to maintain the good performance of the loader. The owner should determine the appropriate gear oil replacement cycle according to the actual situation and use environment of the loader, and choose high-quality gear oil for replacement.
