What is the main function of main bearings?

Main bearings are crucial for supporting the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining proper oil pressure throughout the engine.

Do these bearings come with any installation hardware?

This listing is for the main bearing set only. It does not include any additional installation hardware, such as main cap bolts or assembly lube. You will need to source these separately and refer to the manufacturer's installation instructions.

What is the sizing of these main bearings?

The 'P10' in the part number MS685P10 indicates that these are 0.010 inch undersize bearings. This sizing is intended for crankshafts that have been machined undersize to correct for wear or damage.
