MAN L21/31; CYLINDRICAL PINS (Code EN1P1228)

Written by

Cylindrical pins with code EN1P1228 are precision alignment elements used throughout the MAN L21/31 engine to ensure the correct positioning of components such as casings, housings, and covers. Manufactured from hardened steel, these pins provide repeatable and stable assembly, reducing mechanical wear and improving servicing accuracy. Their role in maintaining geometric consistency across critical joints makes them vital for the long-term mechanical stability of the engine.

The cap nut M33x2, bearing code 11.01296-0071.A, is a specialized fastening component used in conjunction with tie rods or studs in the MAN L21/31 engine. Its robust design allows it to sustain repeated tightening cycles and maintain a secure hold under vibration and thermal stress. Accurate torque application on the cap nut ensures a leak-free and vibration-resistant seal, making it a small yet indispensable part of engine reliability during long-term operation.

MAN L21/31; TIEROD (Code 11.01295-0311.C)

Written by

The tie rod with code 11.01295-0311.C is a critical structural component in the MAN L21/31 engine, used to securely fasten the cylinder head to the engine block. Designed to endure extreme mechanical loads and thermal expansion, the tie rod ensures uniform clamping force across the combustion chamber. Its high-tensile steel construction and precise machining are essential for maintaining engine integrity, reducing distortion, and preventing leaks during high-pressure operation—especially vital in marine and power generation applications.
