Troubleshooting & FAQ
How do I confirm this bearing shell fits my specific engine model?
While this part is listed for a wide range of Yamaha and Parsun 90-115HP models, always cross-reference the OEM part number (115-05010002 for Yamaha, PAF115-05010002 for Parsun) with your engine's service manual or parts diagram. If you are unsure, contact us with your engine's serial number.
Is this the upper or lower bearing shell?
This part is specified as "Bearing Shell A," which corresponds to the upper/main bearing shell for the crankshaft in the compatible models.
What are common signs that a crankshaft bearing is failing?
Symptoms of a worn or failing crankshaft bearing include a persistent knocking or rumbling sound from the engine, low oil pressure, and the presence of metallic shavings in the engine oil during an oil change.
Can I replace just one bearing shell, or should they be replaced in a set?
It is best practice to replace all main bearing shells at the same time to ensure even wear, consistent oil clearances, and balanced engine performance. Replacing a single shell can lead to premature failure of other components.
What is the recommended replacement interval?
Crankshaft bearings do not have a standard replacement interval and are typically replaced only during a complete engine overhaul or when signs of wear or failure are detected.
What is the difference between this bearing and an OEM part?
This aftermarket part is designed to meet or exceed OEM specifications for fit, material, and performance. The primary difference is the price point, as we source directly from the manufacturer.
