Troubleshooting & FAQ
How do I know if this bearing fits my outboard engine?
This needle bearing is designed for Yamaha 75HP, 80HP, 85HP, and 90HP 2-stroke outboard models from 1984–2015. To guarantee fitment, always compare the required part number from your service manual with 93310-835U8-00 and check the detailed engine compatibility list on this page.
What are the signs of a failing crankshaft bearing?
Common symptoms include a persistent knocking, rumbling, or grinding noise from the engine block, especially when under load. You may also notice increased engine vibration or find metallic particles in the engine oil during an oil change.
Do I need special tools for installation?
Yes, professional installation is recommended. A mechanical or hydraulic press is required to properly install this press-fit bearing without causing damage to the bearing, crankshaft, or engine block.
When should crankshaft bearings be replaced?
Crankshaft bearings do not have a fixed replacement interval. They are typically replaced during a complete engine overhaul or if they show signs of failure, such as excessive noise or a sudden drop in oil pressure.
