Troubleshooting & FAQ
How do I know if I need the "Red" bearing versus another color?
Crankshaft bearings are often color-coded to indicate minute differences in size for achieving precise oil clearances during engine assembly. The correct color depends on measurements of the crankshaft journal and engine block bore. Always consult your official service manual or a qualified marine mechanic to determine the exact color-coded bearing your engine requires.
What are the signs of a failing crankshaft bearing?
Common symptoms of a worn crankshaft bearing include a deep, rhythmic knocking or rumbling sound from the engine (engine knock), low oil pressure, excessive engine vibration, and the presence of metallic particles in the engine oil during an oil change.
When should crankshaft bearings be replaced?
Crankshaft bearings are not replaced on a routine maintenance schedule. They are typically replaced only during a major engine overhaul or rebuild, or if they have failed, which is diagnosed by symptoms like engine knock or low oil pressure.
Will this bearing fit my Yamaha F115 outboard?
This part is listed as a direct cross-reference for Yamaha part number 6EK-11417-30, which is used on some F115 models. However, Yamaha may use different bearing specifications across different production years or serial number ranges. You must verify the required part number for your specific engine before ordering.
Is this bearing pre-lubricated?
No. New bearings are coated with a protective anti-corrosion film but are not pre-lubricated for operation. It is critical to thoroughly lubricate the bearing with clean, new engine oil upon installation to prevent immediate engine damage.
