Use of gear oil pump

The use of gear oil pump precautions:

1, timely oil change. The new oil should be changed according to the designated oil change indicator. When there is no oil analysis method, the oil can be changed according to the deadline. The recommended oil change period for the automobile manufacturer is 30000-48000km. When the oil is changed, the old oil should be discharged hot. , And clean the gear and gear box before adding new oil. When refueling, should prevent the mixing of water and impurities.

2, the amount of fuel should be appropriate. The amount of oil should be appropriate, not too much or too little. Too much not only increases churning resistance and fuel consumption, but also may cause gear oil to mix into the brake drum (if not sealed) resulting in brake failure; too little will Poor lubrication, excessive warming, and accelerated gear wear will adversely affect gear maintenance. The gear oil level should generally be added flush with the lower edge of the gearbox fill port, and the gear tanks should always be inspected for leaks. Keep the oil seals and gaskets intact.

3. The use of gear oil pumps is beneficial to the maintenance of gears. The gear oil has a long service life. If a single-stage oil is used, it will use different viscosity labels during seasonal maintenance. If the used oil is not replaced within the oil change period, it can be used when the oil is changed again. The old oil should be kept properly. Storage, rigorous waterproofing, mechanical impurities and waste oil pollution.

4. Do not mix the SAE classification labels for oil and gear oil. In order to avoid squeezing in the calculation scale, the grading marks designated as high are used for gear oils, and the low grading labels are used for engine oils. However, for the old grade gear oils, the grading number is lower. Attention should be paid to gear oil pumps and engines. There is no link between the oil viscosity levels, and the same model cannot be used. Never use gear oil as the engine oil. Otherwise, severe problems such as burnt tiles, sticky cylinders, and sintered piston tops can occur.

5. Don't mistake the lubrication function of high viscosity gear oil. The use of gear oils with a viscosity that is too high will result in a significant increase in fuel consumption. It will also be detrimental to the repair and maintenance of gears. In particular, it will have a greater impact on high-speed cars and appropriate multi-stage gear oils should be used as much as possible.

6, can not use ordinary gear oil pump instead of hypoid gear oil. Why do you say it? Due to the large sliding between the teeth of the hypoid gear pump, the ordinary gear oil pump cannot maintain a sufficient lubrication film. If common gear oil is used between them, the hypoid gear will be damaged quickly. How to distinguish the common gear oil in use Hyperboloid gear oil? A: The color of dip-type hypoid gear oil is generally yellow-green to dark green and dark brown, etc. The color of other gear oils is generally dark-black. Note the difference in use. It should not be abused to replace the hypoid gear oil. Ordinary gear oil, otherwise, it will cause erosive wear and unnecessary economic loss of the transmission gear. It is necessary to select the proper gear oil according to the characteristics of the gear transmission.

7, gear pump use taboo, from the perspective of gear pump repair and maintenance. In use, it is strictly prohibited to add diesel oil to the gear oil to dilute, do not affect the winter start and baking the rear axle, transmission, so as to avoid serious gear oil Deterioration. If this situation arises, it should be replaced with low-viscosity multi-stage gear oil.
