The pinion with code number K 32325 is a small but powerful gear mounted on the pinion shaft of the ZV40/48 diesel engine. This component engages with a larger gear to transmit torque and rotational energy with high precision. Its compact, hardened design allows it to withstand high stress and rapid motion, making it ideal for critical timing or drive mechanisms. The pinion's performance directly influences the efficiency and durability of gear transmissions, contributing to the reliable function of various auxiliary systems within the engine.
The bush coded K 32304 is a precision-engineered insert used inside the housing K 32301 of the ZV40/48 engine. It acts as a protective and low-friction interface between moving mechanical parts, especially where shafts rotate or slide. Manufactured from a wear-resistant, self-lubricating material or a high-grade metal alloy, the bush reduces metal-to-metal contact, extending the lifespan of the housing and adjacent components. Its role is vital in maintaining alignment, minimizing wear, and ensuring the smooth operation of the engine’s gear systems.
The worm gear with code number K 32322 is a critical drive component in the horizontal worm gear assembly of the Sulzer ZV40/48 diesel engine. Designed to transmit motion and torque efficiently at a right angle, this gear ensures smooth and precise rotational movement between the worm shaft and the gear wheel. Its robust construction from high-strength, wear-resistant alloy allows it to endure heavy loads and continuous operation under harsh marine and industrial conditions. The precision-cut gear teeth contribute to reduced vibration, minimal backlash, and long-lasting performance in the engine’s auxiliary systems.
The piston rings, code P50605-02, form a critical seal between the piston and cylinder wall in the MAN L21/31 engine. Typically consisting of compression and oil control rings, they serve to contain combustion gases, transfer heat from the piston to the liner, and regulate oil consumption. Manufactured with precision and durability in mind, these rings ensure proper sealing, reduced blow-by, and optimized lubrication—key factors in prolonging engine life and maintaining consistent performance under harsh operational conditions.
The piston, code P50602-03, is a high-performance component at the heart of the MAN L21/31 engine’s combustion cycle. Made from heat-resistant alloys, it endures explosive pressures and high temperatures while moving rapidly within the cylinder liner. Its carefully engineered crown shape maximizes combustion efficiency, while its light weight and strength reduce inertia and wear. Designed for long service life, this piston plays a key role in fuel efficiency, emission control, and overall engine performance.
The connecting rod, code P50603-02, is one of the most vital components in the MAN L21/31 engine, serving as the mechanical link between the piston and the crankshaft. Engineered to withstand extreme tensile and compressive forces, this forged steel rod converts the reciprocating motion of the piston into rotational movement, delivering efficient power transmission. Its precision-machined bearing surfaces and optimal weight balance are critical to minimizing vibration and maintaining high mechanical integrity during continuous operation in marine and stationary power generation environments.
