Troubleshooting & FAQ
How do I confirm this bearing fits my specific engine?
Check your engine model against the compatibility table. The surest method is to cross-reference the part number stamped on your original bearing with the numbers in our Part Number Matrix (818184, 875302, 875330).
What are the signs of a failing connecting rod bearing?
Common symptoms include a persistent, rhythmic knocking or tapping sound from the engine (rod knock), which often changes with RPM. Low oil pressure, metallic particles in the engine oil, and eventual engine seizure are also indicators.
What is the difference between part number 818184 and 875302/875330?
Part number 818184 was the original OEM part number. It was later superseded by Volvo Penta to parts 875302 and 875330. They are functionally identical and fully interchangeable for the specified applications.
Do I need special tools for installation?
Yes. Installing connecting rod bearings is an advanced mechanical task. You will need a torque wrench, plastigauge for checking oil clearances, and other standard engine rebuilding tools. Professional installation is highly recommended.
