The disk identified with code number K 72149 is a precision-machined component essential for the smooth functioning of the geared pump K 72106 in the ZV40/48 engine. Its main role is to ensure stable rotation and optimal torque transmission within the pump assembly. Built from wear-resistant materials, this disk endures continuous mechanical stress and high temperatures, making it indispensable for maintaining consistent fluid flow and pressure. Its reliability directly affects the efficiency and durability of the engine’s lubrication or fuel system, depending on the pump's function.
Crankshaft bearings, commonly associated with code H33016, play a vital role in supporting the crankshaft within the engine block, enabling smooth rotation under heavy loads. In the MAN L21/31, these bearings endure significant mechanical and thermal stresses. Failure or excessive wear in crankshaft bearings can lead to severe engine damage. Therefore, consistent inspection, lubrication, and prompt replacement are critical for maintaining engine health and avoiding costly repairs.
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.
