The locking screw with code number K 32393 is a precision-engineered fastener used to secure cover K 32301 on the Sulzer ZV40/48 diesel engine. Its main function is to maintain a tight and vibration-resistant seal over the barring engine housing, ensuring operational stability and preventing unintentional loosening during engine service. Made from durable, corrosion-resistant materials, this screw is vital for long-term reliability and safety in demanding industrial or marine environments.
The screw plug with code 06.08042-0127.A, conforming to DIN908 standards and sized M60x2ST, is a specialized fastener designed to securely seal threaded openings in the MAN L21/31 engine’s oil or coolant systems. Made for high reliability under pressure and thermal cycling, this plug ensures leak-proof closure while allowing for service access when needed. Its precision engineering and robust construction contribute to the overall safety and maintenance efficiency of the engine.
The gasket with code 06.56936-2355.0 serves as a vital sealing element within the MAN L21/31 engine, preventing fluid or gas leakage between critical surfaces such as cylinder heads, covers, and manifolds. Engineered from high-temperature and pressure-resistant materials, this gasket plays an essential role in maintaining combustion efficiency, system integrity, and environmental compliance. Its proper fit and function are indispensable for avoiding performance losses and potential mechanical failures.
The material specification document with code 11.00196-0001 is a critical reference that defines the exact chemical and mechanical properties required for components used in the MAN L21/31 engine. It outlines the quality standards, treatment processes, and tolerances that ensure each part meets the engine's high-performance and durability requirements. Strict adherence to this specification guarantees component reliability under demanding marine and industrial conditions, supporting engine longevity and operational safety.
The screw identified by code number K 33421 serves as a locking component for the serrated bolt-locking device K 33420 in the Sulzer ZV40/48 engine. Though small, this screw is essential in maintaining secure connections under vibration-heavy conditions. By preventing loosening of the bolt-locking mechanism during engine operation, it plays a crucial safety role and ensures mechanical stability, especially in parts of the engine where high-speed rotation and repeated stress cycles are the norm.
The connecting rod shaft, marked with code K 33101, is an integral part of the engine’s powertrain, acting as the central axis around which the connecting rod pivots. This shaft must offer both torsional rigidity and fatigue resistance, as it is continuously subjected to rotational loads and high-frequency vibrations. In the Sulzer ZV40/48, it helps synchronize the movement of pistons with the crankshaft, contributing to engine efficiency and smooth operation across various load conditions.
