4679165 Hitachi Excavator Fuel Filter for ZX450-3

Part number 4679165 is the original fuel filter (diesel fine filter) provided by Hitachi for the ZX450-3 large hydraulic excavator. As shown in the figure, this component is a fuel filter assembly with a transparent observation window. Its universal models usually cover ZX450-3 and its large tonnage models on the same platform (such as ZX470, etc.). As a key filtering component of the original factory, its interface size, flow rate, and filtering accuracy are fully matched with the high-pressure common rail fuel system of the engine

This product is a rotary fuel filter with a transparent window. The assembly consists of two parts. The left side is a transparent engineering plastic filter cup, which is equipped with a high-precision pleated filter element (shown in dark brown/orange in the picture). Its function is to efficiently filter out micron sized particulate impurities in diesel; The right side is a silver gray aluminum alloy die-casting base, which integrates an oil inlet, an oil outlet, and a manual exhaust bolt (usually located at the top). The design of the transparent window facilitates visual inspection of the degree of filter contamination and whether the oil contains water. Its filtration accuracy can usually reach below 10 microns, and it has oil-water separation function, which is the "kidney" that protects modern high-pressure common rail engines.
