The bush with code number K 73021 is a vital component within the cooling water pump assembly of the Sulzer ZV40/48 diesel engine. Acting as a guide and wear-resistant surface for the rotating shaft, this bush minimizes friction and helps ensure smooth operation of the pump. Made from durable, corrosion-resistant materials, it withstands continuous exposure to water and thermal cycles. Its reliability directly impacts the cooling efficiency and overall health of the engine, making it essential for long-term marine and industrial use.
The piston is a critical moving part in the MAN L21/31 engine responsible for transferring combustion force to the crankshaft via the connecting rod. Manufactured from durable materials to withstand extreme pressure and temperature, the piston plays a central role in the engine’s power generation and efficiency. Regular inspection and maintenance of pistons help prevent engine wear and sustain performance.
The complete cylinder unit is a fundamental assembly in the MAN L21/31 engine that houses the combustion chamber and associated components. This unit is engineered to withstand high pressure and temperatures while ensuring effective sealing and combustion efficiency. Proper maintenance of the cylinder unit is essential for optimal engine performance and longevity.
The axle is a vital structural component in the MAN L21/31 engine. It supports rotational elements and ensures the precise alignment of moving parts within the engine assembly. The robust design of the axle contributes to the overall stability and smooth operation of the engine, reducing wear and preventing mechanical failures during continuous heavy-duty operation.
The spring plate designated by code K 72140 works in conjunction with the flexible rod K 72135, providing essential tension and support within the ZV40/48 engine assembly. It helps absorb vibration and maintain precise rod alignment during engine operation. This component ensures the flexible rod can transmit force or motion reliably, especially in systems where accurate movement is critical, such as fuel injection or lubrication control. Manufactured from resilient, wear-resistant material, the spring plate enhances both operational stability and service life of connected parts.
The threaded pin marked as code K 72148 serves as a key fastening and pivot element for the levers K 72127 and K 72130 in the Sulzer ZV40/48 engine. Designed for strength and precise alignment, this pin ensures secure and smooth articulation of the lever mechanisms involved in actuation or control systems. Its threaded design allows for tight, vibration-resistant assembly, contributing to long-term mechanical stability and accurate system function under dynamic load conditions. This small component plays a big role in maintaining engine control integrity.
