What are the taboos when using the oil pump? From the perspective of oil pump repair and maintenance, we first need to talk about the following points.

1、 In use, it is strictly prohibited to add diesel oil to gear oil for dilution, and do not bake the rear axle and transmission due to affecting the starting in winter, so as to avoid serious deterioration of gear oil. If this happens, use low viscosity multi-stage gear oil.


2、 Do not confuse the classification mark of oil and oil pump. In order to avoid confusion in the calculation standard, it is specified that the high grade is used for gear oil, and the low grade is used for engine lubricating oil. But the grade of gear oil of old brand is lower. It should be noted that there is no relationship between the viscosity grade of gear oil and engine oil, and the same model cannot be used for each other. Do not use gear oil as engine oil, or serious accidents such as burning tile, sticking cylinder and sintering piston top will occur in the engine.


3、 Reasonable use of oil pump is conducive to gear maintenance. The service life of gear oil is long, such as using single-stage oil, and changing different viscosity grades when changing seasons for maintenance. If the old oil discharged does not reach the oil change period, it can be used when changing the oil again. The used oil shall be kept properly to prevent water, mechanical impurities and waste oil pollution.

4、 Change oil timely. The new oil shall be replaced according to the specified oil change index. If there is no oil quality analysis method, the oil can be replaced according to the specified time limit. The oil change period recommended by automobile manufacturers is 30000-48000km. During oil change, the old oil shall be drained while it is hot, and the gear and gearbox shall be cleaned before adding new oil. When refueling, it is necessary to prevent water and impurities from mixing.


5、 The quantity of oil shall be appropriate. The quantity of oil shall be appropriate, neither too much nor too little. Too much will not only increase the resistance of oil stirring and fuel consumption, but also may cause the brake failure due to the gear oil mixing into the brake drum through the rear axle housing (if the seal is poor); too little will cause poor lubrication, too high temperature, accelerate the gear wear, and cause adverse effects on gear maintenance. Generally, the gear oil level shall be added to be flush with the lower edge of the gearbox oil filler, and the leakage of each gear oil tank shall be checked frequently, and the oil seal and gasket shall be kept in good condition.
