The torsion spring/scale (code KS 72141) in the Sulzer ZA40S engine plays a vital role in maintaining precise mechanical balance and controlled movement of various engine components. Designed to store and release energy efficiently, this component helps regulate forces within the engine, reducing wear and ensuring smooth operation. Manufactured from high-strength materials, the torsion spring is built to endure continuous stress and harsh working conditions. Routine checks and timely replacements are essential to maintaining its functionality, ultimately contributing to the engine’s performance and longevity in demanding marine and industrial applications.
