4611025 Original Excavator oil Filter for ZX200

Part number 4611025 is one of the original oil filters provided by Hitachi for the ZX200 series hydraulic excavator. According to the supplier information, the part number clearly corresponds to the hydraulic oil filter, and its applicable models cover ZAX120-1, ZX200-6, ZX200-3, ZX230 and other models. Special attention should be paid to the ZX200 model equipped with the ISUZU 6BG1T engine

This product is a rotary full flow oil filter, which is the core filtering component of the engine lubrication system. Its main function is to filter out metal wear particles, carbon deposits, dust and other impurities in the engine oil, ensuring that the oil entering each friction pair of the engine is highly clean, thereby effectively protecting precision components such as the crankshaft, camshaft, turbocharger, etc. Modern construction machinery engines have extremely high requirements for oil cleanliness. Such filter elements usually use high-performance composite filter materials (such as cellulose and fiberglass blends), with high filtration accuracy (able to intercept particles of 20-30 microns) and high pollutant holding capacity. The filter is equipped with an integrated check valve (to prevent oil backflow after engine shutdown, which may cause oil shortage during startup) and a bypass valve (to open when the filter element is clogged or the oil is viscous at low temperatures, ensuring continuous oil supply). Its working parameters are perfectly matched with the engine lubrication system, which is a key barrier to protect the engine and extend its lifespan.

Replacement cycle: Strictly follow the maintenance standard of replacing every 500 working hours or every 6 months, and shorten the cycle in harsh working conditions such as high dust and heavy loads. Replacement steps: 1 Heat engine pressure relief: Start the engine to operating temperature and then turn off the engine to allow the oil to flow and remove impurities. 2. Disassemble old parts: Place an oil pan under the filter and use a special filter wrench to unscrew the old filter counterclockwise. 3. Cleaning and preparation: Wipe the installation surface of the filter seat on the engine with a clean cloth. Apply a uniform layer of new engine oil on the rubber sealing ring at the top of the new filter (4611025). 4. Installation: Use your hand to screw the new filter into the base until the sealing ring contacts the base, and then use a tool to tighten it by 3/4 turn (about 20-25 N · m).
