The main rocker shaft, with code number H 27032, is a core mechanical axis in the valve train of the ASL25 engine. It supports and guides the movement of rocker arms, translating camshaft motion into precise opening and closing of engine valves. Built for strength and stability, the shaft must endure continuous stress from reciprocating forces while maintaining perfect alignment for optimal valve timing. Proper lubrication and machining precision are essential for its longevity. As a backbone of the valve mechanism, the main rocker shaft significantly influences engine breathing efficiency and overall performance.

The rubber seal identified by code number H 27096 serves a critical sealing function in the ASL25 diesel engine, ensuring that fluids such as oil or coolant remain contained within their designated pathways. Designed to be flexible and resistant to wear, this seal adapts to surface irregularities and prevents contamination or leaks under both static and dynamic conditions. Whether positioned in rotating or fixed joints, the rubber seal’s resilience to heat, pressure, and chemical exposure makes it indispensable to maintaining operational integrity and reducing the risk of mechanical failure.

The compression spring with code number H 16173 is a vital energy-storing component within the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 diesel engine. Designed to absorb and release mechanical force, this spring is used in various assemblies, particularly where controlled motion or force regulation is essential. Its coiled structure resists compressive loads, helping maintain pressure or tension between components in valve gear or control systems. Engineered from high-strength steel, it ensures durability and consistent performance under cyclic stress, playing a key role in preserving the precision and reliability of the engine’s moving parts.

The conical pin, carrying the code H11155, is a small yet indispensable fastening element in the mechanical assemblies of the ASL25 diesel engine. Its tapered shape allows for precise positioning and tight fixation of engine components, minimizing play and enhancing structural integrity. Often used in conjunction with moving parts or high-stress assemblies, the conical pin helps distribute loads evenly and maintain alignment during operation. Despite its modest size, this pin contributes significantly to the mechanical stability and long-term durability of the engine system.

The pipe seal marked with code number H16331 is an essential element of the ASL25’s fluid management system. Designed to ensure a tight and leak-free connection between engine piping and key components, this seal is exposed to fluctuating temperatures and vibrations. Its robust design and material composition make it highly resistant to wear and deformation, which is vital for long-term reliability. A properly functioning pipe seal not only supports efficient fluid transfer but also helps maintain environmental and operational safety in both stationary and marine engine applications.

The seal identified by code number H16524 plays a fundamental role in preserving the internal integrity of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 engine. This component is designed to prevent the leakage of fluids such as oil or coolant, ensuring consistent pressure and protecting sensitive engine internals from contamination. Crafted from high-grade sealing materials, the H16524 seal withstands heat, pressure, and mechanical stress during extended engine operation. Its correct installation and regular inspection are crucial for maintaining system efficiency and preventing costly downtimes due to fluid loss or internal damage.

The special bolt, marked with code number K 28035, is engineered for mounting the main rocker arm K 28005 within the complex mechanism of the ZV40/48 diesel engine. This bolt must withstand extreme loads and maintain the precise geometry of the engine’s moving parts. Its design allows for precise fitting and maximum resistance to bending and shear forces, which is crucial for the smooth operation of the valve system. The reliability of this bolt directly affects engine performance, making proper installation and periodic inspection critically important.

The lock nut, designated by code number K 28038, is a critical safety element in the construction of the Sulzer ZV40/48 engine. Designed to secure the special bolt K 28035, this nut prevents the bolt from loosening during engine operation, thereby protecting vital components from potential damage. Its robust construction and precise threading ensure consistent clamping force and assembly stability, even under intense vibrations and load changes. Regular checks of its tightness are vital for engine safety and operational durability.

The spring cage, identified by code number K 28042, is an integral part of the valve train assembly in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Designed for use with spring K 28041, this component serves as a protective and stabilizing structure that ensures proper guidance and function of the spring under high loads. Made from durable materials, the spring cage withstands strong mechanical forces and ensures reliable system operation in demanding working conditions. Proper installation and regular maintenance of this component are essential for the longevity and precision of the mechanical assembly.

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.
