The coupling halves identified by code K 72120 form a mechanical link between the drive shaft and the geared pump in the Sulzer ZV40/48 engine. Designed to transmit torque smoothly and absorb minor misalignments, these coupling halves ensure reliable power transfer under high load and continuous use. Their precise fit and robust construction help maintain the integrity of the pump assembly, contributing to the overall reliability and efficiency of critical systems such as lubrication or fuel delivery.
The lever marked with code K 72127 is designed to interact with the flexible rod K 72135, providing mechanical advantage and precision movement within control or regulation systems of the ZV40/48 engine. It serves as a critical linkage point, translating linear or rotary force to drive auxiliary mechanisms such as lubrication or fuel regulation. Constructed for strength and precision, this lever plays a key role in ensuring responsive and consistent engine performance under varying operational loads.
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.
