Choosing the right hydraulic fluid is critical when it comes to hydraulic system maintenance for Caterpillar excavators. As a key part of the excavator's power transmission, the hydraulic oil filled with the hydraulic oil must meet strict quality and performance requirements. In general, it is recommended to use factory-certified or compatible anti-wear hydraulic fluids for Caterpillar excavators, such as HM or ISO6743/4HM hydraulic fluids that meet DIN51524 standards. When refueling the hydraulic tank of a Caterpillar excavator, it is important to ensure that the hydraulic fluid has good viscosity and temperature characteristics, oxidation resistance and excellent shear stability, so as to effectively protect the precision components of the hydraulic system, extend the life of the excavator, and improve the efficiency of the excavator. In addition, it is necessary to replace the hydraulic system regularly according to the instructions in the equipment operation manual to ensure the cleanliness and stable performance of the hydraulic system. In summary, when filling the hydraulic tank of a Caterpillar excavator, be sure to use a high-quality hydraulic fluid that is officially certified for this type of excavator.
