Troubleshooting & FAQ
How do I know if this bearing kit fits my specific Volvo Penta engine?
This kit is a replacement for OEM part REC875307. The most reliable way to confirm fitment is to check your engine's service manual or cross-reference the part number on your original bearings. As specific model compatibility is not listed, direct verification against your old part number is essential before purchasing.
What are the signs of a failing main bearing?
Common symptoms include a deep, rumbling or knocking sound from the bottom of the engine that often changes with RPM, low oil pressure readings, and the presence of metallic particles (bearing material) in the engine oil and filter during an oil change.
Is any special preparation needed before installation?
Yes, absolute cleanliness is critical for a successful installation. Both the crankshaft journals and the bearing housing surfaces in the engine block must be immaculately clean and free of burrs or scoring. Use a quality assembly lubricant on the bearings and journals before assembly to prevent dry startup.
