The expansion bolt with code number K 34127 is a specialized fastener used in securing the upper part of the piston in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Designed to endure high thermal loads, this bolt compensates for expansion and contraction during engine operation, maintaining consistent tension and alignment. Its ability to flex slightly under heat ensures structural integrity and prevents stress fractures in the piston assembly. This precision-engineered bolt plays a critical role in extending piston life and ensuring reliable engine performance under extreme conditions.

The rubber plate identified with code number H 87616 serves as a versatile insulating and cushioning element within the ASL25 diesel engine system. Typically used between structural components, it absorbs vibrations, prevents direct metal-to-metal contact, and helps maintain alignment during engine operation. Its durable and flexible material resists chemical exposure and mechanical stress, making it ideal for use in harsh engine environments. This seemingly simple component plays an essential role in reducing wear and enhancing overall operational stability.

The spiral seal bearing code H 81153 is engineered to offer advanced sealing performance in rotating or reciprocating engine parts of the ASL25 diesel engine. Its spiral geometry increases surface contact and resilience against pressure fluctuations and mechanical wear. This seal is especially suited for high-speed or high-temperature environments where traditional seals might degrade quickly. By maintaining fluid integrity and reducing the risk of leakage, the spiral seal contributes to longer engine lifespan and minimized maintenance needs.

The O-ring with code number H 82514 is a fundamental sealing component in the ASL25 diesel engine from Adriadiesel/Jugoturbina/Zgoda/Sulzer. Designed to ensure leak-proof connections between engine components, this ring-shaped rubber element is crucial in preventing the escape of fluids or gases under pressure. Its elastic structure allows it to adapt tightly between metal surfaces, maintaining a secure seal even under thermal expansion or vibration. The O-ring is vital for engine efficiency and safety, especially in high-pressure fuel, oil, or air systems.

The pressure connection, designated by code number H 87603, is an essential interface point in the fluid or gas distribution system of the ASL25 diesel engine. This component enables the secure transfer of pressurized media—such as oil, fuel, or air—between different parts of the engine or connected systems. Its robust construction is designed to endure high pressure and temperature conditions, ensuring leak-free performance and maintaining system integrity. The precision engineering behind the pressure connection supports reliable engine functionality and safety in demanding operational environments.

The component referred to as “Blunt,” with code number H 74127, serves a specialized role within the ASL25 diesel engine. Though modest in size and appearance, this element may function as a physical stop, alignment tool, or load distribution element, depending on its specific application within the engine assembly. Engineered for strength and resilience, the blunt component ensures stability and positional accuracy of other parts, especially under high vibration or load. Its importance is often recognized in preventing misalignment or damage in high-performance engine operations.
