Manufactured from heat- and wear-resistant materials, this component withstands high temperatures and repeated impact, maintaining its shape and functionality over time. A properly fitted valve seat is crucial for preserving engine compression, improving fuel efficiency, and supporting smooth combustion cycles.

The bearing cushion for the column axle-half, marked with code H 12020, plays a crucial role in supporting rotational movement within the ASL25 engine. Positioned strategically to reduce vibration and absorb loads, this cushion ensures smooth operation and protects the shaft from wear. Its precise design allows for balanced pressure distribution and long-lasting performance even under heavy-duty conditions. As a key component in the bearing system, it significantly contributes to the overall mechanical stability and efficiency of the engine.

The cylinder cover bolt with code H 11113 is a fundamental fastener in the ASL25 diesel engine, responsible for securely fastening the cylinder head to the engine block. Operating under extreme pressure and thermal conditions, this bolt must provide a reliable and durable seal to maintain compression and prevent leaks. Precision-engineered and made of high-strength material, it is designed to resist stretching and fatigue over prolonged engine use. Regular inspection and proper torque application are vital to ensure the engine’s operational integrity and performance.

The upper spring plate, designated as K 27501, is part of the inlet valve assembly in the ZV40/48 diesel engine. Positioned at the top of the valve spring, it evenly distributes the spring force and helps maintain correct alignment of the inlet valve during operation. This plate must withstand high cyclical loads and elevated temperatures, making material strength and structural integrity crucial. A well-functioning upper spring plate ensures reliable valve movement, which is vital for efficient air intake and overall engine breathing performance.

The piston with code K 27404 is an integral part of the starting valve mechanism in the ZV40/48 engine. It plays a central role in regulating the airflow during the start-up sequence, moving within the valve body to open or close the passage for compressed air. This piston must be machined with exact tolerances to ensure airtight operation and swift response under pressure. Its condition significantly influences the performance of the entire starting system, and regular inspection is critical to prevent starting failures.

The complete starting valve, marked with code K 27400, is a key component in the starting system of the Sulzer ZV40/48 diesel engine. This valve controls the admission of compressed air into the cylinder during engine start-up, initiating piston movement before combustion begins. Engineered for high precision and durability, the starting valve must function flawlessly under extreme pressure and temperature conditions. Its reliability directly affects the engine's ability to start smoothly and efficiently, making it essential for safe and dependable operation in marine and industrial settings.

The adjustment screw with code number H 27217 plays a fine-tuning role within the ASL25 diesel engine’s mechanical system. It is typically used to calibrate clearances or positions in critical assemblies, such as valve gear, injector settings, or control mechanisms. Precision in its design ensures accurate, repeatable adjustments that can withstand operational vibrations and thermal expansion. This small but essential part directly influences engine efficiency, performance, and longevity, making it a key element in regular maintenance and tuning procedures.
