Yanmar YANMAR - N21 -VALVE STEM SEAL - 146670-11640
The VALVE STEM SEAL (Part No. 146670-11640) is a precision sealing component used in YANMAR N21 marine diesel engines. It is designed to control lubricating oil flow along the valve stem, preventing excessive oil from entering the combustion chamber while ensuring proper lubrication of valve components. This helps maintain efficient combustion and reduces carbon deposits. This seal is suitable for YANMAR N21, 6N21, and 8N21 marine diesel engines.
