What is the main function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on and are crucial for maintaining proper oil pressure throughout the engine.

Are these bearings undersized or oversized?

The part number MS1265P10 indicates that these are standard size bearings. Always verify your crankshaft journal measurements before ordering to ensure you have the correct size.

What should I check before installing these bearings?

Before installing, ensure your crankshaft journals are clean, smooth, and within the manufacturer's specified tolerances. Any debris or damage on the journals can lead to premature bearing failure.
