The stud with code 06.06136-2817.0 is a dual-threaded fastener used in the MAN L21/31 engine for securing components such as cylinder heads, covers, or housings. Featuring threads on both ends, this stud enables strong mechanical connections through nut fastening while allowing precise alignment and reusability during engine maintenance. Manufactured from high-strength steel to withstand thermal expansion and vibration, it ensures structural integrity in high-stress applications common in marine and power-generation settings.
The snap ring coded K 27029 is a circular retaining element used to lock flange K 27026 in place within the ZV40/48 diesel engine structure. Designed to fit into a machined groove, it provides axial retention and prevents disassembly of connected parts due to pressure fluctuations or mechanical motion. This compact yet essential component is made from spring steel or similar resilient materials to ensure consistent clamping force and durability. Its proper function supports the secure fit and alignment of the starting valve assembly.
The nut with code K 27039 is a precision fastener designed specifically for securing stud K 11122 within the ZV40/48 diesel engine assembly. Built to resist vibration, high torque, and thermal cycling, it plays a critical role in maintaining mechanical stability across connected components such as covers, manifolds, or housings. Its precise threading and high-strength alloy composition ensure tight fastening without loosening during operation, contributing to engine safety and long-term reliability.
The flange coded K 27035 is a robust connection interface used to mount the starting valve securely to the engine block of the ZV40/48 diesel engine. Engineered for precise alignment and high-pressure sealing, this component ensures stable positioning and proper airflow during the engine’s pneumatic start-up phase. Manufactured from corrosion-resistant and pressure-tolerant material, the flange helps maintain system integrity under thermal stress and vibration. Its function is essential in ensuring leak-free and reliable engagement of the starting system, especially in marine and heavy-duty industrial applications.
The locking spring washer, code 06.16169-0006.1, is designed to exert consistent tension on fasteners, helping to maintain clamping force in the MAN L21/31 engine even under thermal cycling and vibration. Its spring-like profile compensates for any loosening tendencies in bolted connections, ensuring mechanical reliability over time. Commonly used in high-stress areas, this washer is vital for the safe and uninterrupted function of engine components.
The cover, code 11.01213-0061.A, serves as a protective enclosure in the MAN L21/31 engine, designed to seal off internal engine compartments from external contaminants such as dust, moisture, or debris. Engineered with precision fit and durable materials, this component not only helps retain oil and fluids but also contributes to thermal insulation and noise reduction. Its presence is crucial for preserving internal cleanliness and ensuring reliable engine performance under harsh operating conditions.
