YA00002973 Excavator Engine Fuel Filter for Hitachi ZX180-5B

The original fuel filter (part number YA00002973) is a genuine engine fuel filter component of the Hitachi ZX180-5B excavator, mainly used for the fuel supply system of the Isuzu 4JG1 or Yangma 4TNV98 series diesel engines equipped on this model. The universal number YA00002973 of this filter is its unique identifier in Hitachi's original accessory system, ensuring complete compatibility with the specifications of the host fuel pump, injector, and pipeline interface. When ordering, it is necessary to provide the complete model and engine serial number of the excavator for verification to avoid mismatches.

This product belongs to the rotary diesel filter (also known as "diesel grid") specifically designed for construction machinery, and complies with the GB/T 20080-2017 "Road Vehicle Fuel Filters" standard. Its structure consists of an aluminum shell, stainless steel inner bracket, and high-efficiency filter paper (chrysanthemum shaped folding), with a filtration accuracy of up to 5 µ m, which can effectively intercept particulate impurities, moisture, gum, and microorganisms in fuel. The main technical indicators include: rated flow rate ≥ 30L/h, initial resistance ≤ 8kPa, compressive strength ≥ 500kPa, and oil-water separation function (separation efficiency ≥ 95%). The sealing ring of the original filter element is made of fluororubber material, ensuring long-term sealing reliability within the temperature range of -40 ° C to+120 ° C.

It is recommended to replace the filter every 500 hours of work or every 6 months, and shorten it to 250-300 hours in dusty, high humidity, or low-quality fuel conditions. Before replacement, the engine should be turned off and the fuel system pressure should be released. It is strictly prohibited to smoke or use open flames while operating in a cold state. When disassembling the old filter element, it is necessary to clean the sealing surface of the installation seat. Before installing the new filter element (YA00002973), a small amount of clean diesel should be applied to the sealing ring, and attention should be paid to the direction of the arrow (pointing towards the engine inlet end). Manually tighten according to the torque specified in the maintenance manual (usually 25-35N · m). Daily use of clean diesel that meets national/European standards, regular discharge of fuel tank sediment water, and inspection of oil circuit joints for leaks. Regular replacement can effectively prevent fuel injector blockage, oil pump wear, and engine power reduction, ensuring stable operation of the equipment.
