YA00008662 Excavator Filter Element for EX1200-6

Part number YA00008662 is the original fuel filter element (oil-water separator filter element) provided by Hitachi for large hydraulic excavators such as EX1200-6. This component is clearly applicable to Hitachi EX1200, EX2600, EH3500AC and other models. As the core unit of fuel system filtration, it is used to efficiently intercept solid particles, moisture, and gum in diesel, and protect precision components such as high-pressure common rail injectors and fuel pumps. Its common codes may include SN200874, 20056739, 15504915, etc., but the use of non-standard spare parts is strictly prohibited to avoid fuel system blockage or damage.

This product is a Hitachi pure fuel filter cartridge, made of high-performance fiberglass filter paper or composite material. The filtration accuracy is usually 3-5 μ m, and the water separation efficiency can reach over 95%. The typical structure is a folding design to increase the filtering area and reduce flow resistance; The shell is usually made of metal or high-strength plastic, with a wide sealing surface and reliable sealing to prevent unfiltered fuel leakage. The working pressure range is about 0.2-2.0MPa, the flow rate is about 5L/min, and the working temperature range is -20 ℃ to+120 ℃, suitable for high vibration and dusty working environments of construction machinery.

Replacement cycle: It is recommended to replace every 500-1000 working hours, and in environments with poor fuel quality and high humidity, it should be shortened to 300-500 hours. Daily inspection: Check the appearance of the filter element for leaks and whether the water level in the water cup is too high every week. Drainage operation: If equipped with a transparent water cup, press the drainage valve to release the accumulated water before starting each day. Replacement steps: 1 Close the fuel cut-off valve and disconnect the negative terminal of the battery; 2. Use a specialized tool to loosen the filter element and pay attention to collecting any spilled fuel; 3. Clean the sealing surface of the filter seat and apply a small amount of clean diesel on the sealing ring of the new filter element; 4. Manually tighten the filter element until the sealing ring contacts the filter seat, and then rotate it 3/4-1 turn; 5. Restore power, start the engine and check for leaks.
