Pin for Crankshaft (Code Number K 31039)

Written by

The pin with code number K 31039 is a precision-machined component used in the crankshaft assembly of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. It ensures accurate alignment and secure positioning of critical rotating parts, supporting both mechanical balance and structural integrity. Designed to withstand heavy loads and repeated stress cycles, this pin contributes significantly to the engine’s reliable performance. Despite its modest size, it plays a crucial role in maintaining the overall geometry and durability of the crankshaft system under demanding conditions.

The nut marked with code number K 31038 is designed to securely fasten bolt K 31022, which anchors the counterweight (K 31020) to the crankshaft of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. This high-strength fastener ensures that the counterweight remains precisely in place during intense operational conditions, maintaining rotational balance and minimizing vibrations. Manufactured for durability and exact fit, the nut resists loosening under mechanical and thermal stress, playing a key role in preserving the structural integrity of the engine's core components.

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.

The spacer, designated by code number K 32327, is a support element used in the installation of worm gear K 32326 within the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Though often overlooked due to its simple appearance, the spacer plays a vital role in ensuring the correct axial positioning and alignment of the worm gear on the shaft. By maintaining the proper clearance between moving components, it helps reduce friction and mechanical wear, ultimately extending the service life of the gear assembly. A properly fitted spacer is crucial for maintaining the gear system's integrity and smooth operation under continuous load.
