What should be noted when using Rexroth gear pumps? Can it be used with confidence right after purchase, without having to worry about maintenance? Many users encounter various problems. Today, Autos will tell you what aspects need to be taken into consideration when using Rexroth gear pumps after purchasing them. 　　I. During use. It is strictly prohibited to add diesel or similar substances to gear oil in order to dilute it, nor should the rear axle and transmission be heated in order to avoid problems with starting in winter, as this can cause the gear oil to deteriorate severely. If this occurs, a low-viscosity multi-stage gear oil should be used. 　　II. Do not confuse the classification codes for engine oil and oil pumps. To avoid confusion in the classification standards, it is specified that higher grade numbers are used for gear oil, while lower grade numbers are used for engine lubricants. However, the grade rating for old-grade gear oils is lower. It should be noted that there is no connection between the viscosity grades of gear oil and engine oil, and oils of the same type cannot be used interchangeably. Under no circumstances should gear oil be used as engine oil, otherwise the engine may suffer serious problems such as bearing burnout, cylinder sticking, and piston head sintering. 　　III. Proper use of oil pumps is beneficial for gear maintenance. Gear oil has a long service life; if a single-grade oil is used, switch to an oil with a different viscosity grade during seasonal maintenance. The old oil that has been drained can be reused in the next oil change, provided it is still within the valid period for use. Used oil should be stored properly to prevent contamination by moisture, mechanical impurities, and waste oil. 　　IV. Change the oil at the appropriate time. New oil should be replaced according to the specified oil change criteria; in the absence of oil quality analysis methods, the oil can be changed at the prescribed interval. The oil change interval recommended by automobile manufacturers is 30,000–48,000 km. When changing the oil, the old oil should be drained while it is still hot, and the gears and gearbox should be cleaned thoroughly before new oil is added. When refilling, prevent moisture and impurities from entering. 　　V. The amount of fuel added should be appropriate. The amount of oil should be appropriate, neither too much nor too little. Too much oil not only increases the resistance to oil circulation and fuel consumption, but it may also cause the gear oil to enter the brake drums through the rear axle housing (if the sealing is poor), leading to brake failure; too little oil results in inadequate lubrication, elevated temperatures, and accelerated gear wear, which has negative effects on gear maintenance. The gear oil level should generally be adjusted to be at the same level as the lower edge of the gearbox filling port. It is also necessary to regularly check for leaks in each gearbox and to ensure that all oil seals and gaskets are in good condition.
