COMPLETE ROCKER

Function and technical context

The complete rocker arm is a critical component of the timing system that transmits the movement of the camshaft to the intake and exhaust valves, synchronizing their opening and closing precisely with respect to the crankshaft. Installed in the cylinder head, this mechanism regulates the flow of the fuel mixture into the combustion chambers and the evacuation of residual gases in each engine cycle. A worn or damaged rocker arm causes imbalances in valve timing, resulting in loss of power, excessive fuel consumption and the risk of water entering the combustion chamber during navigation in adverse conditions.

When to replace this part?

Typical wear symptoms include abnormal metallic noise coming from the cylinder head, irregular vibrations during acceleration, and difficulty maintaining a constant idle. It is recommended to inspect the condition of the rocker arm at each seasonal maintenance check and replace it preventively if signs of visible wear, cracks or deformation on the contact surfaces are detected. The preventive change avoids sudden navigation breakdowns and costly out-of-water repairs.
