Yanmar YANMAR - N21 -ROLLER TAPPET - 137600-14220
The Roller Tappet is a precision valve train component used in YANMAR N21 / 6N21 / 8N21 marine diesel engines to transfer camshaft motion to the valve system with reduced friction. It ensures smooth valve operation, accurate timing, and improved mechanical efficiency.
Designed for marine diesel engine applications, this roller tappet minimizes wear, supports stable valve actuation, and enhances the reliability of YANMAR N21, 6N21, and 8N21 engines.

ENGINEX MARINE is a well-known supplier of YANMAR marine diesel engine spare parts, covering models such as NY16, N18, N21, M200, M220, T220, T240, T260, N165, S165, S185, Z280, N260, N280, N330, HAL, EY18, EY22, EY26, and EY17.
The roller tappet is manufactured from high-strength alloy steel with a precision-ground roller surface to ensure smooth contact with the camshaft. It operates under high mechanical loads, continuous rolling contact, vibration, and elevated engine temperatures. Its design reduces friction compared to flat tappets, minimizes wear on the camshaft, improves valve timing accuracy, and enhances overall engine efficiency and reliability in YANMAR N21, 6N21, and 8N21 marine diesel engines.
