The intermediate wheel complete plays a key role in the MAN L21/31 engine’s timing system. It transmits rotational motion between gears within the timing gear train, ensuring accurate synchronization of the crankshaft and camshaft. This precise coordination is vital for maintaining correct valve timing, optimizing engine performance, and preventing mechanical failures.

The fresh water pump complete is a vital part of the MAN L21/31 engine’s cooling system. It circulates fresh water coolant throughout the engine to absorb and dissipate heat generated during combustion. Reliable operation of the fresh water pump ensures stable engine temperatures, protects against overheating, and supports overall engine efficiency and durability.

The lubricating oil cooler in the MAN L21/31 engine is a critical component responsible for regulating the temperature of the engine’s lubricating oil. By efficiently removing excess heat from the oil, it helps maintain optimal viscosity and lubrication properties, preventing overheating and reducing wear on moving parts. Proper functioning of the oil cooler is essential for prolonging engine life and ensuring consistent, reliable performance.

The thrust ring, code number K 32386, is specifically designed to support axial loads generated by the worm gear K 32323 in the Sulzer ZV40/48 diesel engine. Positioned to absorb and distribute force along the shaft, the thrust ring ensures smooth gear engagement and minimizes wear. Precision-engineered for fit and strength, it enhances the performance and reliability of the worm gear assembly, preventing misalignment and prolonging service life in high-load operational conditions.
