The housing for the roller guide in the MAN L21/31 engine is a crucial structural part that supports and guides the roller bearings in the valve train. This housing ensures precise alignment and smooth movement of components, reducing wear and enhancing durability. Its robust construction helps maintain engine reliability by preventing misalignment and mechanical failure in the valve operation system.
The governor and governor drive are essential components in the MAN L21/31 engine responsible for regulating engine speed and maintaining stable operation under varying loads. The governor ensures the engine runs at the desired RPM by adjusting fuel delivery, preventing overspeeding, and optimizing performance. This precise control system is critical for both engine safety and efficiency, especially in demanding marine and industrial applications.
Designed specifically to support flexible rod K 72135, the spring guide with code K 72137 ensures proper alignment and controlled movement of the rod within the mechanical system of the Sulzer ZV40/48 engine. This component helps maintain tension and reduces the risk of unwanted deflection or vibration, especially under dynamic operating conditions. Made from durable materials and engineered for high precision, the spring guide extends the lifespan of connected parts and contributes to smoother overall engine performance.
The locking screw with code K 73034 is a seemingly small but essential fastening element designed for securing the casing of the cooling water pump in the Sulzer ZV40/48 engine. Its primary function is to hold the casing parts in position under pressure, vibration, and thermal expansion, preventing any misalignment or leakage. Precision-engineered and built to withstand mechanical stress, this screw contributes directly to the durability and stability of the entire cooling system. Regular inspection and correct torque application are key to ensuring its effectiveness.
The bearing housing marked with code K 73111 is a critical structural component within the raw water pump assembly of the Sulzer ZV40/48 diesel engine. This housing securely encases the pump bearings, maintaining their alignment and protecting them from contaminants such as water and debris. Its robust construction ensures that the bearings operate smoothly under heavy load and variable speed conditions. By minimizing vibration and allowing consistent rotation of the pump shaft, this component plays a vital role in ensuring the reliability of the engine’s cooling system.
The connecting rod in the MAN L21/31 engine transfers the piston's reciprocating motion into the crankshaft’s rotational motion. Made from high-strength forged steel, it must endure significant forces and dynamic loads. Its sturdy construction and precise design are vital for reliable and efficient power transmission in the engine.
