The thrust ring, code number K 32386, is specifically designed to support axial loads generated by the worm gear K 32323 in the Sulzer ZV40/48 diesel engine. Positioned to absorb and distribute force along the shaft, the thrust ring ensures smooth gear engagement and minimizes wear. Precision-engineered for fit and strength, it enhances the performance and reliability of the worm gear assembly, preventing misalignment and prolonging service life in high-load operational conditions.

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.

The raw water pump, with code number K 73100, plays a critical role in the Sulzer ZV40/48 diesel engine’s cooling system. Its primary function is to circulate seawater or another external water source through the engine's heat exchangers, preventing overheating during operation. Built for durability and corrosion resistance, this pump handles high flow rates and harsh marine environments. Its efficient performance ensures stable engine temperatures, contributing significantly to the reliability and longevity of the engine under continuous load.

The indicator valve, identified by code H 27750, is an essential diagnostic component used in the ASL25 diesel engine to monitor cylinder pressure during operation. By allowing temporary connection to pressure gauges, it provides critical insight into combustion performance and engine health. Built to endure high pressure and thermal cycles, the valve ensures safe and reliable readings. This makes it an invaluable tool for maintenance teams aiming to optimize performance, detect issues early, and extend engine life.

The oil scraper marked as H 34028 plays a vital role in controlling oil distribution within the ASL25 engine. This component ensures that excess lubricating oil is removed from the cylinder walls during piston movement, preventing oil buildup and minimizing consumption. Its precision design helps maintain optimal lubrication, reduces emissions, and protects engine parts from unnecessary wear. Regular inspection and replacement of the oil scraper are essential to maintaining engine efficiency and complying with environmental standards.

The spring with code number H 43627 is a resilient mechanical component designed for critical use within the ASL25 diesel engine system. Its primary function is to store and release mechanical energy, either to maintain pressure, absorb shock, or ensure proper positioning of connected elements. Built from high-quality, fatigue-resistant material, this spring withstands demanding operational conditions typical of marine and industrial environments. Whether part of a valve mechanism or a tensioning system, its reliability directly affects engine performance and longevity.

The flywheel with gear rim is a vital component of the MAN L21/31 engine that combines energy storage with gear engagement. The flywheel stabilizes engine rotation by storing kinetic energy, while the gear rim facilitates connection to the starter motor for engine ignition. This dual-function part is essential for smooth engine starts, balanced operation, and consistent power transmission.

The housing for the roller guide in the MAN L21/31 engine is a crucial structural part that supports and guides the roller bearings in the valve train. This housing ensures precise alignment and smooth movement of components, reducing wear and enhancing durability. Its robust construction helps maintain engine reliability by preventing misalignment and mechanical failure in the valve operation system.

The governor and governor drive are essential components in the MAN L21/31 engine responsible for regulating engine speed and maintaining stable operation under varying loads. The governor ensures the engine runs at the desired RPM by adjusting fuel delivery, preventing overspeeding, and optimizing performance. This precise control system is critical for both engine safety and efficiency, especially in demanding marine and industrial applications.

Designed specifically to support flexible rod K 72135, the spring guide with code K 72137 ensures proper alignment and controlled movement of the rod within the mechanical system of the Sulzer ZV40/48 engine. This component helps maintain tension and reduces the risk of unwanted deflection or vibration, especially under dynamic operating conditions. Made from durable materials and engineered for high precision, the spring guide extends the lifespan of connected parts and contributes to smoother overall engine performance.
