4616545 Excavator Fuel Filter for Hitachi ZX210-6G

The original fuel filter 4616545 is designed and used in conjunction with the Hitachi ZX210-6G (approximately 21 ton class) crawler excavator. This universal number is the unique identifier for Hitachi genuine parts, ensuring that it matches the pressure and flow parameters of the main engine fuel pipeline interface and high-pressure common rail fuel system perfectly. This filter mainly ensures the ZX210-6G model equipped with Isuzu or Yangma National III/IV emission standard engines, and may also be compatible with other equipment of the same series using the same fuel system. However, it is strongly recommended to check the main engine model and this universal number when replacing to ensure filtering efficiency and sealing reliability.

As shown in the picture, this product is a genuine Hitachi original accessory, with a black cylindrical metal shell as the main body, manufactured by Hitachi Construction Machinery Co., Ltd. located in Thailand. The surface of the shell is silk screened with the words "HITACHI" and "Filter, FUEL" in white, with clear markings. It uses multi-layer composite high-performance filter materials internally, with excellent impurity retention ability and moisture separation function, which can effectively filter micron sized particles, colloids, and moisture in fuel, protecting precision components such as high-pressure fuel pumps and injectors from wear and corrosion. The sealing structure design is rigorous to ensure no leakage throughout the entire working pressure range.

It is recommended to replace the fuel filter every 500 hours of work or every 6 months. If working under poor oil quality or dusty conditions, the replacement time should be shortened to 250-300 hours. Before replacement, it is necessary to clean the surrounding area of the filter seat. During installation, apply a small amount of clean fuel to the sealing ring of the new filter, tighten it by hand, and then use tools to tighten it to the specified torque (usually 3/4 to 1 turn) to avoid excessive tightening. Be sure to use the original 4616545 filter, which has undergone rigorous testing for filtration accuracy and durability. High quality diesel that meets the standards should be refilled in daily life, and the accumulated water at the bottom of the fuel tank should be regularly drained to ensure fuel cleanliness from the source, in order to maintain optimal engine performance and extend the service life of the fuel system.
