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

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining precise oil clearance for lubrication.

Do these Clevite main bearings come with new main cap bolts?

This set includes the main bearings themselves. New main cap bolts are typically sold separately, and it's recommended to use new, properly torqued bolts for a reliable engine rebuild.

What is the significance of the 'A20' in the part number MS2249A20?

The 'A20' typically indicates a specific size or clearance specification for the bearing. In this case, it refers to a standard size bearing, meaning it's intended for a crankshaft that is within factory specifications.
