Connecting rods in the MAN L21/31, with an estimated code of H33001, serve as the crucial link between pistons and the crankshaft, translating reciprocating motion into rotational energy. Bearings, approximately H33016, support the connecting rods and reduce friction between moving parts. Due to constant mechanical stress, these components are prone to wear and require regular monitoring and maintenance to prevent catastrophic engine failure and ensure smooth operation.
The MAN L21/31 engine relies heavily on its pistons and piston rings, crucial components for maintaining engine compression and efficient combustion. Pistons, estimated at code H27222, withstand intense heat and pressure while transferring force to the crankshaft. The piston rings, likely coded around H31110 series, provide a critical seal between piston and cylinder walls to prevent gas leakage and control oil consumption. Regular inspection and timely replacement of these parts are vital for optimal engine performance and longevity.
The spindle coded K 87088 is a key internal part of the pressure regulating valve in the Adriadiesel ZV40/48 engine. This spindle transmits motion from the actuator to adjust the flow and pressure within the valve body, directly influencing fuel or lubrication regulation. Crafted to tight tolerances, the spindle ensures accurate control under fluctuating operational demands. Its performance directly affects the valve’s responsiveness, making it crucial for maintaining engine stability, fuel efficiency, and protection against overpressure scenarios.
The sleeve identified by code number K 81265 serves as a bearing surface for the hinge component K 81264 in the ZV40/48 engine framework. Designed to reduce friction and ensure smooth pivotal movement, the sleeve also helps maintain proper alignment and mechanical stability in moving joints. Its durable construction, typically from wear-resistant materials, makes it ideal for repeated cycles of motion. This component enhances operational precision and contributes to the overall structural robustness of the engine’s supporting assemblies.
The O-ring marked with code number K 87094 is a precision-sealing component designed specifically for housing K 87086 within the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine system. This small but vital part plays a crucial role in preventing fluid leakage and maintaining system pressure by ensuring a tight seal between mating surfaces. Made from high-performance elastomers resistant to temperature extremes and chemical exposure, the O-ring supports reliable engine function even in demanding conditions. Its integrity is essential for the longevity and safety of the pressure-related components it protects.
The threaded union with code number K 84468 is a precision-engineered connector used in the visual flow control system of the Sulzer ZV40/48 engine. It enables secure and leak-free joining of flow monitoring components, allowing operators to observe and assess fluid movement within the system. Designed for high-pressure environments, the union features durable threads and sealing surfaces to ensure long-lasting reliability. This small but essential part supports effective maintenance and diagnostics, making it indispensable in complex fuel, oil, or coolant monitoring setups.
