The support identified by code number K 81170 is an essential structural component used in the installation and stabilization of exhaust piping in the ZV40/48 engine. It ensures that the exhaust system is securely mounted and properly aligned to withstand thermal expansion, vibration, and operational stress. By providing a stable base, the erection support prevents displacement or misalignment of the exhaust components, contributing to a more durable and noise-reduced exhaust configuration.
The guide bolt marked with code number K 81162 is a precision-machined component that plays a vital role in securing and aligning the guide element within the Sulzer ZV40/48 diesel engine. Its purpose is to ensure that moving parts stay correctly positioned during engine operation, which is crucial for smooth and efficient motion transmission. Designed to endure high mechanical loads, this bolt minimizes wear and helps maintain the geometry of critical engine assemblies, thereby enhancing overall performance and reliability.
Connecting rods, estimated with code E265280020 for the MAN L21/31, are vital mechanical links that transfer the reciprocating motion of pistons to the rotational motion of the crankshaft. Manufactured from high-strength forged steel alloys, these rods must withstand tremendous dynamic loads and stresses. Their precision design and durability are crucial for reliable engine operation and longevity, making them one of the core components in the L21/31’s powertrain.
The water pump in the MAN L21/31 engine, likely identified by code H27075, is a critical component of the engine’s cooling system. It circulates coolant throughout the engine block and cylinder head to dissipate heat generated during combustion. Proper functioning of the water pump is essential to prevent overheating, maintain engine efficiency, and ensure safe operation, especially under demanding marine or industrial conditions.
The oil pan, or sump, in the MAN L21/31 engine (estimated code H21420) serves as the reservoir for engine lubricating oil. It collects and stores the oil as it circulates through the engine, ensuring vital components remain properly lubricated to reduce friction and wear. Made from durable materials to withstand thermal stresses and mechanical impacts, the oil pan is essential for maintaining engine longevity and optimal performance by facilitating efficient oil circulation and cooling.
The sealing ring, designated with code number N66068, is a small but essential part that ensures tight sealing between mechanical interfaces in the ASL25 engine. It prevents fluid leaks and contamination, helping to maintain system pressure and protect internal components. Made from resilient, temperature-resistant materials, this sealing ring can withstand the demanding conditions of diesel engine operation. Proper installation and timely replacement of the sealing ring are key to minimizing maintenance issues and maximizing engine lifespan.
