PIN 90250-05046 REC90250-05046

Function and technical context

This pin is part of the fixing and articulation mechanisms of the marine engine, ensuring the correct alignment and stability of critical components in systems such as the transmission, engine mounts or drive connections. Its function is to maintain the relative position of two elements under constant load, avoiding unwanted movements that could cause excessive vibrations, misalignment of the propulsion shaft or entry of water into the sealing areas. Failure or wear of this pin compromises the structural integrity of the installation and can lead to serious secondary damage to other adjacent components.

When to replace this part?

Pins subjected to constant loading and vibration show symptoms of wear such as abnormal looseness in the joints, knocking noises coming from the fixing area, or imperceptible but detectable movements when manually manipulating the components during maintenance. It is recommended to inspect this pin at each seasonal engine inspection, especially after intensive sailing seasons or after impacts that have affected the engine structure. Preventively replacing this element avoids emergency repairs at sea and prolongs the useful life of the transmission and engine support systems.
