Troubleshooting & FAQ
How can I confirm this bearing fits my engine?
First, check the compatibility table on this page to see if your Yamaha model and year are listed. The most reliable method is to cross-reference your existing part's number. This bearing replaces OEM part numbers 93310-620V5 and 93310-620W5.
What are the symptoms of a failing connecting rod bearing?
A worn or failing con rod bearing typically causes a distinct knocking or ticking sound from within the engine, which may increase with RPM. Other signs can include excessive engine vibration, loss of power, and the presence of fine metal shavings in the engine oil.

Yes, this is critical. The needle bearing must be thoroughly coated in clean, high-quality 2-stroke engine oil before being installed to prevent premature failure.

This bearing should be replaced during any major engine rebuild, or immediately if you diagnose symptoms of bearing failure. It is a critical wear item that is essential for engine longevity and performance.
