MAN L21/31; GASKET (Code 06.56936-2355.0)

Written by

The gasket with code 06.56936-2355.0 serves as a vital sealing element within the MAN L21/31 engine, preventing fluid or gas leakage between critical surfaces such as cylinder heads, covers, and manifolds. Engineered from high-temperature and pressure-resistant materials, this gasket plays an essential role in maintaining combustion efficiency, system integrity, and environmental compliance. Its proper fit and function are indispensable for avoiding performance losses and potential mechanical failures.

The material specification document with code 11.00196-0001 is a critical reference that defines the exact chemical and mechanical properties required for components used in the MAN L21/31 engine. It outlines the quality standards, treatment processes, and tolerances that ensure each part meets the engine's high-performance and durability requirements. Strict adherence to this specification guarantees component reliability under demanding marine and industrial conditions, supporting engine longevity and operational safety.

The screw identified by code number K 33421 serves as a locking component for the serrated bolt-locking device K 33420 in the Sulzer ZV40/48 engine. Though small, this screw is essential in maintaining secure connections under vibration-heavy conditions. By preventing loosening of the bolt-locking mechanism during engine operation, it plays a crucial safety role and ensures mechanical stability, especially in parts of the engine where high-speed rotation and repeated stress cycles are the norm.
