The spring identified by code number K 32373 is a small yet essential component paired with the arrestor pin K 32356. Its role is to provide the necessary force to engage or disengage the arrestor mechanism within the Sulzer ZV40/48 engine. This ensures precise locking or release of mechanical elements during operation or maintenance. Made from resilient material, the spring maintains consistent performance under repetitive stress and thermal variation, supporting the safe functioning of the engine’s internal systems.
