The spring plate, with code number K 31027, is an important structural element used alongside the fitted bolt K 31024 and component K 31520 in the crankshaft assembly of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. This plate serves to evenly distribute clamping forces and absorb operational stresses that occur during engine function. By helping to maintain tension and alignment across high-load connections, the spring plate reduces wear and vibration, thereby enhancing the longevity and stability of the engine’s rotating system. It’s a small but vital part in ensuring reliable performance under continuous heavy-duty operation.
