The tightening instruction document, code 11.00160-0152-1.K, provides vital specifications for torque application on critical bolts and fasteners throughout the MAN L21/31 engine. This guide ensures correct tightening sequences and torque values are followed during assembly and maintenance. Precise adherence helps prevent mechanical deformation, seal failures, and structural imbalance, ultimately safeguarding the performance and reliability of the engine under demanding operating conditions.
The measuring points, code FK0831.0, play a crucial role in the routine monitoring and diagnostics of the MAN L21/31 engine. Strategically located across the engine’s mechanical system, these points allow technicians to gather essential data such as temperature, pressure, vibration, or wear indicators during operation. By facilitating early detection of irregularities, these measuring points contribute to preventative maintenance, reduced downtime, and extended engine life, making them indispensable in marine and industrial applications.
The complete "VULKAN" vibration damper K 31510 is designed to minimize torsional vibrations in the Sulzer ZV40/48 engine. Manufactured for performance and durability, it enhances the engine’s lifespan, reduces wear on the crankshaft, and ensures smoother operation even in continuous heavy-duty conditions.
The self-locking nut K 31026 is engineered to provide secure fastening even under conditions of vibration and thermal cycling. Used in the mounting of components K 31024 and K 31520, this nut ensures the reliability of threaded joints, reducing the risk of loosening during operation.
The spring plate with code number K 31027 is a crucial mechanical element used to ensure proper tension and load distribution between components K 31024 and K 31520. It helps stabilize the assembly and absorb shocks, which is especially important in high-vibration environments such as large diesel engines.
The PS (power supply or pump set) for the hydraulic tie rod, code 0743814-5.0, is a specialized system that provides the required hydraulic pressure to operate the tie rod mechanism in the MAN L21/31 engine. Hydraulic tie rods ensure uniform pre-tensioning of cylinder heads, promoting even load distribution and structural stability. The power supply unit is vital for maintaining the precision and reliability of the hydraulic tightening process, especially during engine installation or overhaul.
