Troubleshooting & FAQ
How do I know if this main bearing kit fits my Volvo Penta engine?
This kit is a direct replacement for Volvo Penta part number 875753. The most reliable method for confirming fitment is to check the part number specified in your engine's service manual or by inspecting the number on your existing bearings.
What are the common signs of a failing main bearing?
Symptoms of main bearing failure often include a deep, knocking or rumbling sound from the lower part of the engine that may increase with RPM, low oil pressure readings, and the presence of metallic shavings (bearing material) in the engine oil and filter.
When should main bearings be replaced?
Main bearings are typically replaced during a complete engine overhaul or if they show signs of wear or failure. There is no fixed replacement interval; their lifespan depends on engine hours, maintenance, and operating conditions.
Can I replace just one main bearing?
While technically possible, it is strongly recommended to replace all main bearings as a complete set. This ensures consistent clearances, proper crankshaft alignment, and uniform wear, preventing potential imbalances and premature failure of other bearings.
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.
