The cover with code K 27007 is a vital protective component used in conjunction with the bearing casing K 28000 in the Sulzer ZV40/48 diesel engine. Its primary function is to shield the bearing assembly from external contaminants such as dust, oil mist, and moisture, while also helping to retain internal lubrication. Precision-machined from corrosion-resistant materials, this cover ensures long-term protection of the rotating elements, preserving the alignment and performance of the engine's drive train. By minimizing wear and preventing ingress of harmful particles, it contributes to smoother engine operation and reduced maintenance needs.
The silicone paste sealing material, code EN14AM0.001, is a versatile and high-performance compound used in the MAN L21/31 engine for sealing joints and preventing fluid leaks. Applied during assembly between metal surfaces such as flanges or covers, it fills microscopic gaps and resists heat, oil, and pressure. This packing material enhances engine cleanliness and reduces maintenance by maintaining tight seals over extended service intervals, even under harsh operational conditions.
The hexagon collar nut, code EN89DE12, is a specialized fastening component designed for use with studs in the MAN L21/31 engine. Its collar provides a larger bearing surface, improving load distribution and resistance to loosening from vibrations. Engineered for use in high-torque and high-temperature environments, this nut contributes to consistent clamping force, sealing effectiveness, and long-term joint reliability, especially in critical engine assemblies like cylinder and exhaust systems.
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.
