YAMAHA BUSHING 6E0-45316-09 PAF4-03000003

Function and technical context

This bushing is a fastening and alignment component that is part of the transmission system and structural support of the engine. Its function is to provide a precise anchor point and maintain correct alignment between rotating engine components, avoiding excessive vibrations and misalignments that could compromise overall propulsion performance. A worn or fractured bushing generates mechanical play that directly affects the efficiency of the transmission system and can cause secondary damage to adjacent components if it is not replaced in time.

When to replace this part?

Symptoms of wear in a bushing include abnormal vibrations during acceleration, noticeable mechanical play in the mounting area, metallic noises on startup, and gradual loss of rotational stability of the shaft or coupling. It is recommended to inspect this component during each seasonal maintenance and replace it preventively if any signs of cracks, deformation or wear are observed on its surface. Replacing this bushing preventatively prevents costly repairs resulting from prolonged vibrations that can damage adjacent bearings, seals and couplings.
