YA00033065 Excavator Filter element for ZX200-3

The original filter element part number YA00033065 is the core component of the hydraulic return oil filtration system provided by Hitachi Construction Machinery for the ZX200-3 hydraulic excavator (equipped with 4HK1 engine). This filter element is mainly used to filter metal debris, seal debris, and particulate pollutants in hydraulic oil, protecting precision components such as hydraulic pumps and control valves. Its universal models include 4656608 and 4656605, and are widely applicable to Hitachi excavators of the ZX240-3, ZX330-3, ZX210-3, ZX350 and other series. As an integrated design from the original factory, it is deeply matched with the hydraulic pipeline of the entire vehicle. The use of non-standard auxiliary filter elements is strictly prohibited to ensure filtration accuracy and system reliability.

This product is an original hydraulic return oil filter element, which adopts a folding filter paper structure (chrysanthemum shaped design to increase the filtering area), made of glass fiber composite filter material, and the shell is made of stainless steel or metal mesh. Main technical parameters: outer diameter 156.2mm, inner diameter 98mm, length 431mm, filtration accuracy ≤ 10 μ m, working temperature range -30 ℃ to+120 ℃, maximum working pressure difference ≤ 10MPa. The interface is standard M22 × 1.5 thread, equipped with O-type fluororubber sealing ring. This filter element complies with the ISO 3968-91 flow characteristic testing standard and is suitable for harsh working conditions such as high vibration, high dust, and large temperature differences in excavators.

Replacement cycle: It is recommended to replace every 1000 working hours or every 12 months (whichever comes first); If working in dusty and high load environments, it should be shortened to every 500 working hours. Replacement steps: 1 Release hydraulic system pressure (operate the handle to release pressure at each action position); 2. Position the filter element (usually located on the return line of the hydraulic oil tank); 3. Disassemble old parts (use a special wrench and place an oil pan below); 4. Install new parts (pay attention to the arrow indicating the direction of oil flow 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 slow hydraulic action, system overheating, or abnormal noise, check whether the filter element is blocked; If the hydraulic oil pollution alarm light is on, replace the filter element immediately and check the oil quality.
