This component is essential for maintaining oil cleanliness, ensuring component longevity, and supporting reliable engine operation under continuous load.
The pipe with code 11.01299-0139.0 is a vital fluid conduit within the MAN L21/31 engine system, typically used for transporting oil, coolant, or compressed air between critical components. Engineered for pressure resistance and thermal durability, this pipe ensures uninterrupted flow and structural integrity even under the demanding conditions of marine and industrial operation. Its precise routing and secure fittings contribute to system efficiency and ease of maintenance.
The piston ring coded K 27410 is designed specifically for the starting valve assembly, particularly for part K 27404. It provides a tight seal between the piston and valve housing, preventing air leakage during pressurized starts. Manufactured from high-performance materials, this ring resists deformation, wear, and thermal cycling. Its effectiveness is critical to maintaining the efficiency and responsiveness of the engine's pneumatic starting system.
The housing with code number K 27402 serves as the structural body of the starting valve in the ZV40/48 diesel engine. It encases the spindle and related internal components, providing robust protection and alignment. Built from corrosion- and pressure-resistant materials, this housing ensures the valve operates safely and efficiently under high-pressure air injection. Its design supports quick servicing and dependable engine starts even in harsh marine environments.
The spindle coded K 27401 is a key moving component of the starting valve in the ZV40/48 diesel engine. It functions as the actuator that enables or blocks compressed air flow to the cylinders during engine start-up. Engineered for high precision and durability, the spindle must operate flawlessly under sudden pressure changes and high thermal conditions. Its role is essential for reliable engine ignition and smooth transition to full operation.
The cover with splash tube, code 11.01213-0057-1.0, is an integrated component designed to direct lubricating oil inside the MAN L21/31 engine. It prevents uncontrolled splashing, reduces oil loss, and ensures targeted lubrication of internal parts such as bearings and gears. This component plays a crucial role in maintaining oil cleanliness, reducing wear, and supporting smooth engine operation in demanding conditions at sea or in power plants.
Round steel bars coded EN43AE01100028 are essential raw materials used in the manufacturing and repair of MAN L21/31 engine components. These bars are made from high-grade steel with excellent machinability and strength, enabling them to be transformed into precision-engineered parts such as shafts, pins, or custom fittings. Their consistent diameter and metallurgical properties ensure that the resulting components meet the rigorous demands of marine and industrial engine performance.
The disc with code 11.01299-0138.0 is a key mechanical element in the MAN L21/31 engine, typically used in rotational or sealing assemblies. Its precise machining and material strength allow it to maintain alignment, absorb stress, or serve as a spacer or retainer depending on its location within the engine. This seemingly simple part contributes to overall engine balance, durability, and vibration control, particularly in high-speed and high-pressure operational environments.
