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 handling the immense forces generated during combustion and power delivery.

Are these bearings undersized or oversized?

This is a standard size main bearing set. It is intended for use on crankshafts that are still within their original factory specifications or have been machined back to standard size.

What other parts are typically replaced during a main bearing job?

When replacing main bearings, it's common practice to also replace the connecting rod bearings (also known as rod bearings), oil pump, and oil pan gasket to ensure a complete and reliable engine rebuild.
