What is the main function of crankshaft main bearings?

Crankshaft main bearings are crucial for supporting the rotating crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to spin freely while withstanding the significant forces from the pistons and combustion.

Do these bearings come with installation hardware?

This listing is for the crankshaft main bearing set only. It does not include any additional installation hardware. Always refer to the manufacturer's instructions for any specific hardware requirements.

What is the proper procedure for installing these bearings?

Proper installation is critical for bearing performance and engine longevity. Always consult the manufacturer's official service manual for detailed instructions, including cleaning, lubrication, and torque specifications.
