8943904141 Excavator 6HK1 Diesel Engine Oil Pump 

The original oil pump of Isuzu 6HK1 engine, with part number 8943904141 (also commonly referred to as 8-94390414-0 or L210-0029M), is a genuine original accessory designed specifically for 6HK1 series diesel engines. This oil pump is mainly suitable for Hitachi brand excavators equipped with Isuzu 6HK1 engine, including ZAX200, ZAX240, ZAX330, ZAX360, etc. Meanwhile, it is also applicable to other construction machinery using the same 6HK1 engine
 

The original oil pump 8943904141 is a complete oil pump assembly, belonging to the low-pressure oil pump type. Its core function is to extract oil from the oil pan during engine operation and establish sufficient pressure to continuously and stably deliver the oil to various friction surfaces inside the engine that require lubrication and cooling, such as crankshaft bearings, camshaft bearings, pistons, valve mechanisms, etc. As an original component, it adopts precision manufacturing to ensure that the flow and pressure parameters fully match the design requirements of the 6HK1 engine, thereby ensuring reliable lubrication of the engine under various working conditions, reducing wear, and extending the service life of the engine.
 

To ensure the long-term and reliable operation of the oil pump and the entire lubrication system, regular inspections and preventive maintenance are necessary. It is recommended to check whether the engine oil pressure is within the normal range every 250 hours of operation or once a month, and listen for any abnormal noise from the oil pump. Check the quality of the oil every 500 hours of operation or when changing the oil. If premature deterioration or excessive metal debris is found in the oil, it may indicate internal abnormalities in the lubrication system. Regular replacement of engine oil and oil filters that meet specifications is the most important measure to protect the oil pump. Keep the exterior of the engine clean to prevent dust and impurities from entering the oil passages.
