4034470090 Original Loader Spare Parts Oil Filter for ZW250-6

Part number 4034470090 is a specialized part number for Hitachi's original loader oil filter. This filter is the core filtering component of the engine lubrication system, responsible for filtering out impurities such as metal particles, carbon deposits, gum, and external dust generated by friction inside the engine during the oil circulation process, keeping the engine oil clean, and protecting precision components inside the engine (such as crankshaft, camshaft, turbocharger, etc.) from wear and tear. According to the universal accessory system of Hitachi ZW series wheel loaders, this oil filter is widely compatible with Hitachi or Isuzu engines used in multiple ZW series medium to large loaders. Common models include ZW180, ZW220, ZW250, ZW310, ZW370, etc.

The oil filter is a full flow, rotary disposable filter. Its core function is to deeply filter engine oil through internal high-performance filter materials, ensuring that the oil entering the main oil passage is clean, thereby minimizing engine wear, extending oil service life, and maintaining optimal engine performance. The sealing ring is made of oil resistant and high temperature resistant fluororubber material, ensuring reliable sealing within a wide temperature range of -40 ℃ to 120 ℃ and preventing leakage. The overall design complies with Hitachi's strict original factory quality standards, ensuring filtration efficiency, sealing safety, and service life.

The maintenance core of this filter lies in regular replacement and standardized operation. Replacement cycle: It is necessary to strictly follow the regulations of Hitachi's official maintenance manual and usually replace it synchronously with the engine oil. After replacement, start the engine and let it idle for a few minutes to check for any leaks at the filter interface. Associated maintenance: Hitachi original or equivalent quality engine oil that meets specifications must be used. Every time the oil filter is changed, the engine oil should be changed simultaneously. Regularly check the oil level and quality. If premature deterioration of the oil or abnormal blockage of the filter is found, it is necessary to investigate whether the engine has abnormal wear or poor combustion
