Yanmar YANMAR - N21- VALVE SPRING INSIDE
The valve spring inside is a critical valve train component that ensures the inlet and exhaust valves return to their closed position after each operating cycle. It maintains proper valve seating and timing, contributing to efficient combustion and reliable engine performance in YANMAR N21 / 6N21 / 8N21 marine diesel engines. Accurate spring tension helps prevent valve float and ensures smooth operation under varying engine loads.
