Troubleshooting & FAQ
How do I know if this bearing kit is correct for my engine?
The surest way is to match the part number 876666 from your service manual or the old part. While this kit fits many Volvo Penta diesel engines, always verify the part number before ordering.
What are the signs of a failing main bearing?
Common symptoms include a deep, rhythmic engine knocking sound that increases with RPM, low oil pressure readings, and the presence of metallic particles in the engine oil during an oil change.
Will I need any other parts for this job?
This kit includes the main bearings. Depending on the extent of your engine work, you may also need new connecting rod bearings, thrust washers, rear and front main seals, and assembly lubricants.
What's the difference between main bearings and rod bearings?
Main bearings support the crankshaft within the engine block. Rod bearings are located at the end of the connecting rods where they attach to the crankshaft. Both are critical for engine operation but are distinct parts.
