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.
