Yanmar YANMAR - N21 - SEALVALVE STEM SUCTION - 146673-11650
The SEAL VALVE STEM SUCTION - 146673-11650 is a critical valve train sealing component used on the suction (inlet) valve assembly of YANMAR N21 marine diesel engines. It is designed to regulate lubricating oil flow along the valve stem while preventing excessive oil from entering the combustion chamber through the intake side. Suitable for YANMAR N21, 6N21, and 8N21 engines, it helps maintain efficient combustion, reduce oil consumption, and extend engine service life.
