Yanmar YANMAR - N21 -ROCKER ARM BUSH - 147673-11220
The ROCKER ARM BUSH is a precision-engineered valve train component used in YANMAR marine diesel engines to provide a low-friction bearing surface between the rocker arm and rocker shaft. It ensures smooth rocker arm movement, minimizes wear, and maintains accurate valve operation. Designed for continuous heavy-duty service, the bush contributes to reliable engine performance and extended valve train life.

ENGINEX MARINE is a well-known supplier of YANMAR marine diesel engine spare parts, covering models such as N18, N21, M200, M220, Z280, N260, N280, N330, HAL, EY18, EY22, EY26, and EY17.
The ROCKER ARM BUSH is manufactured from high-quality bearing-grade material and precision-machined to provide excellent wear resistance and dimensional accuracy. Installed within the rocker arm assembly, it supports rotational movement around the rocker shaft while reducing friction and ensuring smooth valve actuation. The bush is designed to withstand continuous oscillating motion, lubrication exposure, vibration, and varying operating temperatures encountered in marine diesel engines. Its durable construction helps maintain correct valve timing, reduce component wear, and improve overall valve train reliability. This component is suitable for YANMAR N21, 6N21, and 8N21 marine propulsion engines and diesel generator sets operating under demanding marine and industrial conditions.
