YA00033486 Excavator Fuel Filter for ZX330-5A

The original fuel filter part number YA00033486 (alias 8983129180) is a fuel fine filter provided by Hitachi Construction Machinery for the ZX330-5A hydraulic excavator (equipped with an electronic fuel injection engine). This filter is mainly used to filter out fine particles, gum, and moisture in diesel, protecting precision components such as high-pressure common rail systems and injectors. Its universal model includes 8-98312918-0 and is widely applicable to Hitachi excavators of the ZX200-5A, ZX250-5G, ZX350-5A, ZX490-5A and other series. As an integrated design of the original factory, it is deeply matched with the fuel pipeline of the whole vehicle. It is strictly prohibited to use non-standard auxiliary filter elements to ensure filtration accuracy and system reliability.

This product is an original fuel filter element, which adopts a folding filter paper structure (chrysanthemum shaped design to increase the filtering area) and is made of wood pulp paper or glass fiber composite filter material. Main technical parameters: height of about 205mm, outer diameter of about 94mm, filtration accuracy ≤ 10 μ m, water separation efficiency ≥ 93%. The working temperature range is -20 ℃ to+100 ℃, the maximum working pressure difference is ≤ 1MPa, the interface is standard M22 × 1.5 thread, equipped with O-type fluororubber sealing ring. This filter element complies with the ISO 4020 fuel filter testing standard and is suitable for harsh working conditions such as high vibration, high dust, and large temperature differences in excavators. It can effectively remove more than 95% of particles larger than 10 μ m in the oil, ensuring that the cleanliness of the fuel system reaches NAS level 9 or above.

Replacement cycle: It is recommended to replace every 500 working hours or every 6 months (whichever comes first); If frequently in dusty environments or using low-quality diesel, it should be shortened to every 250 working hours. Replacement steps: 1 Release the fuel system pressure (unplug the fuel pump relay, start the engine until it stalls); 2. Position the filter (usually located on the engine compartment or chassis oil pipe); 3. Disassemble the old parts (place the oil pan below and loosen the oil pipe clamp); 4. Install new parts (pay attention to the arrow indicating the fuel flow direction and ensure that the sealing ring is intact); 5. System re inspection (start the engine and run it at idle speed, check that there is no leakage at each interface). Fault diagnosis: If there is a decrease in engine power, difficulty starting, or idle shaking, check if the filter is clogged; If the water in fuel warning light is on, drain or replace the filter element.
