The spring H 27705 is a critical control element in the valve train of the Sulzer ASL25 engine, responsible for maintaining precise valve timing by ensuring rapid and consistent valve closure during each engine cycle. Engineered for high fatigue resistance and dimensional stability, this spring performs reliably under repeated compression, elevated temperatures, and continuous dynamic loading. Its carefully calibrated stiffness guarantees optimal contact between camshaft, valve, and rocker mechanism, contributing directly to efficient combustion, reduced mechanical wear, and smooth long-term engine operation.
The valve guide H 27153 is a precision-machined component that ensures accurate axial alignment and controlled movement of the engine valve within the cylinder head of the Sulzer ASL25 engine. Designed to withstand high combustion temperatures, continuous mechanical load, and aggressive operating conditions, this valve guide minimizes stem wear and maintains proper valve seating over long service intervals. Its optimized material composition and surface finish reduce friction, support efficient heat transfer from the valve stem to the cylinder head, and play a crucial role in sustaining stable combustion performance and long-term engine reliability.
The pipe clamp, code 06.66012-1101.0, is an important support component in the MAN L21/31 engine, used to securely fasten pipes and hoses to the engine structure. It prevents unwanted movement, vibration, and mechanical stress on fluid lines, reducing the risk of fatigue or leakage. Designed for durability and precise fit, the pipe clamp supports safe routing of oil, fuel, and cooling lines, contributing to orderly installation, easier maintenance, and dependable engine operation in harsh marine and industrial environments.
The round seal ring, code 06.56933-2418.0, is a critical sealing element in the MAN L21/31 engine, used to prevent leakage at static or dynamic joints within oil, fuel, or cooling circuits. Manufactured from durable, heat- and pressure-resistant materials, it ensures reliable sealing even under demanding operating conditions. By maintaining tight connections and preventing contamination or fluid loss, this seal ring contributes directly to engine cleanliness, efficiency, and long-term reliability.
The plug screw, code 06.08045-0144.0, is a precision sealing fastener used in the MAN L21/31 engine to close threaded ports in lubrication, cooling, or fuel systems. Designed to withstand pressure, temperature fluctuations, and vibration, this component ensures leak-free sealing of inspection openings or fluid channels. Its robust material quality and accurate thread geometry are essential for maintaining system integrity and preventing fluid loss during continuous marine or stationary engine operation.
The connecting rod with cover H 33001 is a precision-engineered power transmission component that converts the linear motion of the piston into rotational motion of the crankshaft in the Sulzer ASL25 engine. Designed to handle high compressive and tensile loads, this assembly ensures accurate alignment of the bearing surfaces and smooth force transfer during every engine cycle. Its robust construction, precise machining, and balanced design minimize vibration and bearing wear, making it essential for efficient combustion energy utilization and long-term durability of the engine’s rotating assembly.
