The piston ring H 34026 plays a crucial role in sealing the combustion chamber of the ASL25 engine, maintaining compression while controlling oil consumption. Positioned on the piston, it prevents gas leakage and ensures efficient power transfer during each combustion cycle. Built from wear-resistant alloys, the ring endures high thermal and mechanical stresses, contributing to both engine efficiency and reduced emissions. Regular inspection and timely replacement of piston rings are essential to sustaining the long-term reliability and performance of the engine.
The pressure lever with code H 43618 is a robust mechanical linkage in the ASL25 engine, responsible for transmitting controlled force within the valve or fuel actuation system. By converting motion into regulated pressure, it ensures that the engine’s internal mechanisms function with precision and stability. Made from hardened materials to resist wear and mechanical stress, the lever supports long service life even under demanding operating conditions. Its role highlights the importance of seemingly small components in maintaining the smooth operation of complex diesel engines.
The distribution valve coded H 43612 is a central component in the ASL25 diesel engine’s fuel and air control system. Its purpose is to regulate the timing and distribution of working fluids, ensuring that combustion occurs at the right moment and under optimal conditions. Designed to withstand high pressure and temperature fluctuations, the valve is precision-engineered to provide consistent performance and durability. Its reliability directly impacts engine efficiency, making it an indispensable part of the overall power generation process.
The indicator valve K 27751 is a vital diagnostic tool in the Sulzer ZV40/48 engine, allowing engineers to measure cylinder pressure during operation. By connecting to pressure gauges, it enables the monitoring of combustion efficiency and detection of potential mechanical issues. Built to withstand extreme pressure and temperature variations, the valve provides reliable performance in demanding conditions. Regular inspection and maintenance of the indicator valve are crucial for ensuring engine safety, performance, and long-term reliability.
The distance piece K 27753 is an important spacer component used in conjunction with the indicator valve of the Sulzer ZV40/48 diesel engine. It provides the necessary alignment and spacing between the valve and its associated parts, ensuring correct operation during cylinder pressure monitoring. Precision machining guarantees that it withstands the stresses of high-pressure conditions without deformation. This seemingly simple piece is essential for the accurate and safe installation of the indicator valve system.
The joint ring K 27761 is a precision sealing component designed for the distance piece K 27753 in the Sulzer ZV40/48 engine. Its main purpose is to provide a tight, reliable seal between mating parts, preventing leaks of gases or fluids during engine operation. Made from durable, heat- and pressure-resistant materials, the joint ring ensures proper function of the indicator valve assembly. Despite its small size, it plays a critical role in maintaining the integrity and efficiency of the engine’s diagnostic systems.
The assembly box spanner, code 11.49001-0532.0, is a specialized tool engineered for precision work on the MAN L21/31 engine’s critical fasteners. Its tailored design ensures a secure fit, minimizing the risk of slippage or damage during maintenance. By providing accurate torque application, this spanner enhances safety and efficiency in engine servicing, making it an essential item in the toolkit of marine and industrial engineers.
Socket spanners with square drive, code EN506L12, are indispensable tools for servicing the MAN L21/31 engine. Designed to deliver precise torque while ensuring a firm grip on fasteners, these spanners allow secure tightening and loosening of bolts under heavy-duty conditions. Their durable construction and compatibility with various attachments make them essential for both routine maintenance and complex repair tasks, supporting engine reliability and performance.
The extension piece, code 11.49003-0083.0, is a practical tool accessory used with the MAN L21/31 engine to provide additional reach and flexibility during assembly or maintenance. By extending the length of a tool, it allows technicians to access bolts and fasteners in hard-to-reach areas without compromising torque or safety. Reliable extension pieces are vital for efficient workflows and reducing downtime in demanding marine and industrial environments.
The valve spindle K 27511 is the hardened, precision-turned stem that transmits motion between the rocker/actuator and the inlet valve head in the Sulzer ZV40/48. Its straightness, surface finish and dimensional tolerance are crucial: the spindle must run true in the valve guide, resist bending under side loads and present a wear-resistant surface for the guide and seal. Made from alloy steel and often surface-hardened or coated, K 27511 directly affects sealing performance and valve timing — scoring, bending or excessive wear on the spindle will degrade combustion efficiency and should trigger guide inspection and component replacement to restore reliable engine operation.
