The nut marked with code number K 73125 is engineered to secure shaft K 73123 within the raw water pump assembly of the Sulzer ZV40/48 engine. Its function is fundamental—locking key rotating components in place to prevent mechanical failure under dynamic load. Designed to resist loosening due to vibration and high-speed operation, this precision nut plays a pivotal role in the long-term reliability and safety of the pump mechanism. Proper torque application and regular checks are essential to maintaining its securing function.
The O-ring designated as code number K 73136 plays a crucial sealing role in the Sulzer ZV40/48 diesel engine, specifically as a gasket for cover K 73118. This seemingly simple but essential rubber component is designed to withstand pressure, temperature fluctuations, and chemical exposure typical of marine and industrial environments. It ensures a tight seal, preventing leaks and maintaining system integrity. A high-quality O-ring like this is vital for protecting internal engine components and ensuring efficient operation over long service intervals.
Fuel filters in the MAN L21/31 engine protect the fuel injection system from contaminants and impurities. By filtering particles and water from the fuel, they maintain clean fuel flow, prevent injector clogging, and ensure optimal combustion. Regular replacement of fuel filters is critical to maintaining engine performance and avoiding costly repairs.
The cylinder head in the MAN L21/31 engine seals the top of the cylinders and houses key components such as valves, fuel injectors, and the combustion chamber. It is vital for engine efficiency and durability, ensuring proper compression and sealing under high combustion pressures. Precision manufacturing and robust materials are essential for its performance and lifespan.
The turbocharger in the MAN L21/31 engine plays a crucial role in boosting engine performance by forcing additional air into the combustion chamber. This increases power output and fuel efficiency while reducing harmful emissions. Designed to operate under extreme heat and high speeds, the turbocharger must be precisely manufactured and regularly maintained to ensure long-lasting and reliable engine operation.
The joint ring bearing code number K 81259 is a sealing element designed for use with the screw plug K 81258 in the Sulzer ZV40/48 engine. Its primary function is to provide a leak-proof seal between the plug and the housing, ensuring that fluids such as oil or coolant remain contained under pressure. Manufactured from resilient and heat-resistant material, the joint ring is essential for maintaining the engine's operational integrity and avoiding performance issues caused by leaks or pressure loss.
