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

Main bearings sit between the crankshaft and the engine block. Their primary job is to support the crankshaft, allowing it to rotate smoothly while maintaining the correct oil clearance. This support is critical for the engine's overall health and longevity.

Do these bearings come with the necessary hardware for installation?

This listing is for the main bearing set only. Typically, installation hardware like main cap bolts would be purchased separately, as they are often specific to the engine build and torque requirements.

What is the typical condition of an engine that would require new main bearings?

Engines needing new main bearings often show signs of wear such as knocking or rumbling noises from the bottom end, especially under load. They are also a standard replacement item during a complete engine rebuild or when installing a new or reconditioned crankshaft.
