26757-47001 Original Loader pilot Filter element Filter for LX26

Hitachi original loader spare parts pilot filter element filter (universal part number: 26757-47001) is a pure hydraulic filter component provided by Hitachi Construction Machinery. As an original spare part, it is designed specifically for Hitachi brand construction machinery to ensure a perfect match with the hydraulic pilot system. This filter is widely compatible with multiple mainstream excavator and loader models from Hitachi, including the Hitachi ZX series (such as...) ZX60、ZX70、ZX110、ZX120、ZX160LC-3、ZX180LC-3、ZX200-3、ZX210LC-3、ZX225US-3、ZX240-3、ZX250LC-3、ZX270、ZX330、ZX360LC Excavators from the EX60-3, EX100, EX200, EX220-2, EX300, EX400-5/6, EX550, EX850, EX1100, etc.
 

The pilot filter element is the "precision guardian" of the hydraulic pilot control system. Its core function is to filter the hydraulic oil flowing through the pilot oil circuit, effectively intercept micrometer level metal debris, dust, gum and other pollutants, and protect precision components such as the pilot pump, proportional valve and servo valve. The filter element is supported by a high-strength metal skeleton, and the internal filter material is precision folded glass fiber or stainless steel sintered mesh, which has high pollutant holding capacity and stable filtration performance. Its filtration accuracy is usually around 3 microns and can withstand working pressure differentials of up to 12 MPa, ensuring structural integrity under high-pressure impact. The sealing ring is made of oil and high temperature resistant nitrile rubber, ensuring reliable sealing within a wide temperature range of -35 ° C to 85 ° C and preventing oil bypass
 

Standardized maintenance is the key to ensuring the efficiency of the pilot filter element and the stability of the equipment. It is recommended to inspect or replace the equipment every 2000 working hours or annually (whichever comes first). If the equipment operates in harsh conditions with high dust and heavy pollution, the maintenance cycle should be shortened as appropriate. The pilot filter element is usually located under the pilot oil source block of the loader, near the accumulator, or behind the cab. The hydraulic system pressure must be completely released before maintenance. After disassembly, the color of the filter paper can be observed to determine the degree of contamination, but it must be replaced when the replacement cycle is reached or severe blockage or damage is found. When installing, pay attention to the direction of the arrow on the filter element to ensure that it points towards the direction of hydraulic return oil, and check whether the sealing ring is intact and installed properly.
