Its precise threading and high-grade material ensure reliable fastening, making it indispensable for maintaining structural integrity and alignment throughout the engine’s working life.

The O‑ring with code K 21404 is a critical sealing element designed for the cylinder liner of the engine. Its primary function is to provide a leak‑proof barrier between the liner and engine block, preventing coolant and combustion gases from mixing. This component endures high temperatures and pressures, maintaining its integrity even under intense thermal cycling. A properly functioning O‑ring is essential for preserving compression and ensuring optimal engine performance over long operational periods.

The upper bearing of the connecting rod, marked H 33021, is an essential wear surface between the connecting rod and crankshaft pin in the Sulzer ASL25 engine. It allows for smooth rotational movement and reduces metal-on-metal contact, thereby preventing damage and minimizing frictional losses. Constructed from high-load, fatigue-resistant materials, this bearing supports the dynamic motion of the engine’s internal components and plays a crucial role in preserving performance and efficiency over long-term use.

The connecting rod bolt, code H 33030, is a high-strength fastener used to secure the two halves of the connecting rod in the Sulzer ASL25 diesel engine. This bolt is engineered to withstand immense tensile and compressive forces during combustion cycles, making it an essential element for the engine’s structural integrity. Its precise threading and torque capacity help maintain engine balance and prevent catastrophic failure, ensuring smooth performance across thousands of operating hours.

The bearing sleeve with code number H 40002 is a critical component in the Sulzer ASL25 engine, designed to support and align rotating shafts while minimizing friction. This sleeve serves as a protective intermediary between the shaft and housing, absorbing wear and maintaining precision alignment under thermal and mechanical stress. Built with high-performance materials, it plays a vital role in extending the service life of the crankshaft system and ensuring reliable operation, especially in marine or industrial environments where durability is key.

The ball bearing with code number K 32388 is a core element in the rotating assembly of the Sulzer ZV40/48 engine, specifically designed to fit into bearing insert K 32332. This high-performance bearing minimizes friction and wear while supporting axial and radial loads during continuous engine operation. Engineered for reliability and precision, it ensures smooth movement within the drive system and contributes significantly to the longevity and performance of the entire mechanical setup.

The sealing component coded K 32394 is designed specifically for the locking screw K 32393 to provide an effective barrier against oil leakage and contamination. In the Sulzer ZV40/48 engine, this seal plays a critical role in maintaining the pressure integrity of the system and protecting internal components from dirt, moisture, and thermal fluctuations. Its precision fit and robust sealing capability support long-term engine efficiency and reduce maintenance requirements.
