Troubleshooting & FAQ
How do I know if this main bearing kit fits my specific engine?
This kit is designed for a broad range of Volvo Penta 5.7L V8 models. The most reliable way to confirm fitment is to match your engine's original main bearing part number to 875751. Please also consult our compatibility table and check against your engine's model and year if possible.
