Troubleshooting & FAQ
How do I know if this bearing kit fits my specific engine?
This kit replaces Volvo Penta parts 875750 and 875750-2. The most reliable method for confirming fit is to match these part numbers to your engine's service manual or an existing part. As detailed compatibility lists are not available, cross-referencing the part number is essential.
What are common signs of main bearing failure?
Symptoms of worn or failing main bearings include a deep, knocking sound from the engine that increases with RPM, low oil pressure readings, and the presence of metallic particles in the engine oil during an oil change.
Do I need special tools for installation?
Yes, professional installation is highly recommended. Specialized tools such as a torque wrench, bearing pullers/drivers, and plastigage for checking clearances are necessary for a correct and safe installation.
Is this a complete kit for a full engine overhaul?
This kit contains the main bearings only. A complete engine overhaul would typically require additional components like connecting rod bearings, piston rings, gaskets, and seals, which are sold separately.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
