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

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining precise oil clearance, which is essential for lubrication and preventing wear.

What is the importance of using the correct assembly lube with main bearings?

Assembly lube is critical for protecting the bearing surfaces during the initial engine startup before full oil pressure is established. It provides a protective film that prevents metal-to-metal contact and scoring.

Does this set include all the necessary main bearings for a complete engine rebuild?

This set, MS459P20, contains the main bearings as specified by Clevite for the intended application. It's important to verify the exact contents against your engine's requirements for a complete rebuild.
