4616542 Original Excavator Fuel Filter for EX120-5

Part number 4616542 is an original fuel filter provided by Hitachi for medium-sized hydraulic excavators such as EX120-5. This component is mainly used for fuel system filtration to protect the engine's fuel injection pump and injectors. Its universal models clearly cover EX-5 series medium-sized models such as EX120-5, EX100-5, EX135-5, as well as some derivative models on the same platform. As a core maintenance component of the original factory, its interface size and sealing performance are completely matched with the engine fuel pipeline. It is strictly prohibited to use non-standard spare parts to avoid poor fuel filtration, decreased engine power, or wear of precision components.

This product is a rotary disposable diesel filter, with a high-strength engineering plastic shell that is matte black in color. The top has a smooth surface that is concave inward, making it easy to install with specialized tools. It adopts high-performance filter paper (usually composite material) internally, with a star shaped folding structure to increase the filtering area, and the filtering accuracy can reach 5-10 microns, which can effectively intercept moisture, gum, and solid particles in diesel. The filter is equipped with a check valve and oil-water separation function, and a transparent water storage cup may be integrated at the bottom. The sealing ring is made of oil resistant rubber to ensure 100% sealing after installation. The typical working pressure is 0.2-0.5MPa, with a temperature resistance range of -30 ℃ to+100 ℃, suitable for the vibration and temperature changes in the engine compartment.

Replacement cycle: Strictly follow the maintenance standard of replacing every 500 working hours or every 6 months, and shorten it to 250-300 working hours in poor oil quality or dusty environments. Replacement steps: 1 Release pressure: Turn off the engine and manually press the fuel pre filter pump vent valve to release system pressure. 2. Disassemble old parts: Place an oil pan under the filter and use a special belt wrench to unscrew the old filter element counterclockwise. 3. Cleaning and Installation: Clean the installation surface of the filter base with a clean cloth, apply a small amount of clean diesel on the sealing ring of the new filter element, screw it into the base by hand until the sealing ring contacts, and then tighten it with a wrench by 3/4 turn (about 20-25 N · m)=
