Yanmar YANMAR - N21 -VALVE SPRING INNER - 145610-11131
The YANMAR N21 VALVE SPRING INNER (145610-11131) is a precision valve train component designed to work in conjunction with the outer valve spring to ensure positive valve closing and stable valve operation. It helps maintain correct valve timing, prevents valve float, and supports efficient engine combustion performance.
Suitable for YANMAR N21 / 6N21 / 8N21 marine diesel engines, this inner valve spring contributes to reliable valve train operation, reduced wear, and extended engine service life under demanding marine conditions.
