The intermediate piece coded K 31513 is a crucial connecting element within the vibration damping system of the Sulzer ZV40/48 diesel engine. Positioned between the crankshaft and the main damper unit, it ensures optimal transfer of rotating mass forces while isolating harmful vibrations. Designed from high-strength materials with precise tolerances, this component helps reduce mechanical stress on engine bearings and structural components. Its role is essential in extending engine lifespan and maintaining smooth and quiet operation, particularly under heavy load conditions.
