The complete cylinder cover, designated by code H 27000, is a major structural and functional component of the ASL25 diesel engine. It encloses the upper section of the cylinder, sealing the combustion chamber and supporting components such as valves, injectors, and cooling passages. This cover must endure high pressures and temperatures, making its integrity vital for safe and efficient engine operation. Precision-engineered and built to last, the cylinder cover plays a central role in maintaining compression, managing thermal loads, and ensuring smooth engine performance in demanding industrial and marine environments.
The bearing cover bolt, marked by code H 11151, is a high-strength fastener used to secure the bearing cover to the engine block in the ASL25 engine. It ensures that the bearing assembly remains tightly enclosed, maintaining the integrity of the lubrication system and preventing bearing movement under dynamic engine loads. Engineered for durability and precise torque application, this bolt is critical for withstanding the stresses of vibration and thermal expansion. Proper installation and maintenance of this bolt help ensure the continued reliability and performance of the engine.
The half ring of the adjacent bearing, identified by code H 12010, is an essential component in the ASL25 diesel engine's crankshaft support system. This semi-circular ring is designed to fit around the bearing housing, ensuring the precise positioning and secure retention of the crankshaft within its seat. By maintaining correct axial alignment and supporting rotational loads, it plays a crucial role in minimizing friction and wear. Made from durable, high-strength materials, the half ring ensures the longevity and operational stability of the engine, particularly under continuous mechanical stress.
The upper spring plate with code number K 27528 is a critical part of the exhaust valve assembly in the ZV40/48 engine. Positioned above the valve spring, it evenly distributes the spring load and holds the assembly in proper alignment during engine operation. This plate must endure high temperatures and dynamic mechanical forces, making its precision and material strength essential. By maintaining stable spring compression, it ensures reliable exhaust valve function, directly supporting combustion efficiency and exhaust management in demanding marine and industrial conditions.
The spherical headed pin, identified by code K 28009, is a precision-machined component used to connect and articulate the main and auxiliary rocker arms (K 28005 and K 28015) in the ZV40/48 engine. Its spherical head allows for smooth rotational and angular motion, reducing friction and wear in the high-stress environment of the valve gear mechanism. Built for strength and reliability, this pin ensures accurate alignment and stable operation of the valve train system, contributing to the overall efficiency and durability of the engine.
The O-ring with code number K 28044 is a small but vital sealing component used in conjunction with flange K 28029 in the Sulzer ZV40/48 engine. It plays a critical role in preventing fluid or gas leaks by creating a tight, reliable seal between mating surfaces. Manufactured from durable, heat- and pressure-resistant materials, this O-ring ensures long-lasting performance even in the harsh conditions of marine and industrial engine environments. Proper maintenance and replacement of this component are essential for preserving engine integrity and avoiding costly system failures.
