The nut coded K 27045 is specifically designed to fasten the stud K 27038 within the ZV40/48 diesel engine assembly. Engineered for strength and resistance to vibration, this component ensures that structural connections remain tight under continuous thermal and mechanical loads. Its precision threading provides a secure fit, helping to preserve alignment and load distribution across the connected parts. Whether part of a cylinder head, manifold, or housing, this nut is essential for the long-term durability and operational safety of the engine.
The O-ring with code number K 27055 is a vital sealing element used in conjunction with ring K 27010 in the ZV40/48 engine. Its main function is to prevent fluid or air leakage at the joint interface, particularly where high-pressure fuel or oil systems operate. Crafted from elastomeric materials resistant to heat, oil, and pressure variations, the O-ring ensures a tight and secure seal even under dynamic engine conditions. Its role is crucial for maintaining system integrity and avoiding performance losses due to leaks or pressure drops.
The insert bush coded K 27107 plays a critical role in the precise and stable mounting of the fuel injection valve in the ZV40/48 diesel engine. It acts as an intermediary sleeve, ensuring proper alignment and seating of the injection valve within the cylinder head. Designed to absorb mechanical stress and prevent wear between metallic surfaces, this component contributes to long-term sealing integrity and consistent fuel delivery. Made from heat- and pressure-resistant materials, it supports the injector’s function under high thermal loads and guarantees reliable engine performance across long maintenance intervals.
Round steel bars, code EN43AE0090, serve as foundational raw materials in the production and repair of various MAN L21/31 engine parts. Known for their high tensile strength, uniform diameter, and machinability, these bars are transformed into essential engine components such as pins, shafts, and mounting elements. Their metallurgical reliability ensures they meet the demanding structural and thermal requirements of diesel engines operating under continuous load.
The spray-nozzle with code 11.01227-0017.A is engineered to provide critical cooling and lubrication to high-heat zones inside the MAN L21/31 engine, such as the piston undersides and cylinder walls. Operating under pressure, it ensures optimal oil atomization and precise fluid delivery, reducing wear and enhancing performance. This component is vital in maintaining thermal balance and extending the service life of engine internals in marine and industrial applications.
The spray nozzle for control drive, code 11.01213-0060-1.0, is a key precision component within the MAN L21/31 engine’s lubrication system. Specifically designed to deliver a fine, targeted stream of oil to the control drive mechanism, this nozzle helps reduce friction and regulate operating temperature. By ensuring reliable lubrication under variable load and speed conditions, it contributes significantly to the overall efficiency and longevity of the engine’s control systems.
