Yanmar YANMAR - N21 - SEALVALVE STEM EXHAUST - 146673-11751
The SEAL VALVE STEM EXHAUST - 146673-11751 is a critical valve train sealing component used on the exhaust valve assembly of YANMAR N21 marine diesel engines. It is designed to control lubricating oil flow around the exhaust valve stem while preventing excessive oil from entering the combustion chamber and exhaust gas passage. Suitable for YANMAR N21, 6N21, and 8N21 engines, it helps maintain efficient combustion, reduce oil consumption, and extend valve train service life.
