Troubleshooting & FAQ
How do I know if this damper bush needs replacing?
Signs of a failing damper bush include increased engine vibration, rattling noises near the ignition coil, or visible signs of wear such as cracking, hardening, or crumbling of the rubber material.
Where is this part located on my specific engine?
The location varies. On smaller Yamaha models (like the F4-F6), it is often found in the engine block assembly. On larger models (F8-F60), it is typically used on the magneto assembly or with other electrical components. Always refer to your engine’s official service diagram to confirm its exact position.
What tools are needed for installation?
Because this is a press-fit component, you will likely need a bench vise, arbor press, or a similar tool to press the new bush into its housing without damaging it. Basic hand tools will also be needed to access the component.
What is the difference between Yamaha part numbers 624-42542-00-00 and 90387-06119-00?
Both part numbers refer to the same functional component. Yamaha often uses different numbers for the same part across different model years or diagram references. They are interchangeable for the applications listed.
