The locking spring washer with code 06.16169-0004.2 is a crucial safety component used in bolted connections within the MAN L21/31 engine. Designed to prevent nuts and bolts from loosening under vibration and thermal expansion, this washer exerts a continuous tension against the fastener head. Its split-ring, spring-like design provides reliable anti-rotation performance, making it essential in securing structural and dynamic parts in both marine propulsion and stationary engine applications.
The control room casing plate, designated by code K 16201, serves as a structural and protective component in the ZV40/48 engine’s control housing system. Designed to shield and support sensitive control elements, this precision-engineered plate ensures mechanical integrity and environmental isolation from contaminants such as dust, moisture, or oil mist. Built from corrosion-resistant materials, the plate also aids in maintaining the correct alignment and rigidity of the casing. It is a key part of the engine’s instrumentation reliability and long-term operational stability.
The tubular sealing element with code K 16227 is engineered to provide secure and resilient sealing for components K 16220 and K 16222 within the ZV40/48 engine system. This tubular design ensures an even distribution of sealing pressure, making it ideal for dynamic assemblies where vibration and thermal expansion are factors. Made from durable and oil-resistant material, it supports the long-term reliability of the sealed components by maintaining airtight and fluid-tight conditions. Its use is essential for both operational safety and reduced maintenance cycles.
The O-ring with code K 21406 is a vital sealing element in the ZV40/48 diesel engine, specifically designed for the cylinder liner interface. Its primary function is to create a pressure-tight seal between the liner and the engine block, preventing the escape of combustion gases and the ingress of coolant into the combustion chamber. Manufactured from high-temperature and chemically resistant elastomer, this O-ring withstands extreme engine conditions while maintaining flexibility and integrity. It plays a crucial role in ensuring proper engine compression and preventing efficiency losses due to internal leaks.
The pipe identified by code 01.93105-2069.C is a robust fluid transport element in the MAN L21/31 engine, commonly employed in oil, cooling water, or air systems. Engineered to withstand pressure, temperature, and vibration, it ensures consistent and uninterrupted flow between engine components. Its correct routing and durability are key to maintaining thermal balance and fluid integrity across the engine’s operating cycles.
The guide pipe with code 11.01132-0023.A serves as an alignment and routing component within the MAN L21/31 engine, often used to position rods, wires, or fluids through designated channels. Its sturdy cylindrical design maintains directional accuracy and prevents chafing or vibration damage, especially in dynamic environments. This part plays a subtle yet critical role in supporting internal coordination and mechanical reliability.
