Installation Notes
Installation of this internal crankshaft bearing is a complex procedure that requires engine disassembly. We strongly recommend that a qualified marine mechanic perform the installation. Always refer to your engine’s official service manual for detailed procedures, torque specifications, and required tools. Incorrect installation can lead to severe engine damage.
Troubleshooting & FAQ
What are the signs of a failing crankshaft bearing?
Common symptoms include a knocking or rumbling sound from the engine, increased engine vibration, the presence of metal shavings in the engine oil upon inspection, and potentially low oil pressure. If you notice any of these signs, it is crucial to have your engine inspected immediately.
How do I confirm this bearing fits my engine?
Please check the "Engine & Model Compatibility" table on this page. Cross-reference your engine's model number, horsepower, and year to ensure it is listed. Verifying the OEM part number (93310-954U1) in your service manual is the most reliable method.
What is the difference between part 93310-954U1 and 93310-954V3?
The part number 93310-954V3 was the original number for this bearing. It has since been superseded by 93310-954U1. Both refer to the same part specification, and this aftermarket bearing replaces both versions.
Can I replace just one crankshaft bearing?
While technically possible, it is best practice to replace all main and connecting rod bearings at the same time during an engine rebuild. This ensures even wear and clearances, promoting engine longevity and reliability.
Is this an OEM or aftermarket part?
This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials and manufactured in an ISO 9002 facility, with batch inspections for consistency.
What are your shipping speeds and costs?
We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free, and expedited options may appear at checkout where available.
What is the warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal use. If any issues arise, contact our support with your order details. Returns are accepted within our standard window for items that are unused and in their original condition. See our policy page or reach out for instructions.
