What is the purpose of rod bearings?

Rod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear in this critical rotating assembly, while also helping to maintain oil pressure.

Are these bearings a specific size or standard size?

The part number CR4042SM indicates a standard size bearing set. If you require an undersize or oversize bearing, you would need to consult King Engine Bearings' catalog for the appropriate part number.

What should I do before installing these bearings?

Before installation, it's crucial to clean the crankshaft journals thoroughly and ensure they are within the manufacturer's specified tolerances for roundness and taper. Always follow the manufacturer's recommended torque specifications during installation.
