What is the primary function of main bearings?

Main bearings sit between the crankshaft and the engine block. Their main job is to reduce friction and support the crankshaft as it rotates, keeping it properly aligned within the engine.

Are these bearings undersized or oversized?

This set, MS970AL, is a standard size bearing set. It is designed to fit crankshafts that are still within their original factory specifications.

What else might I need when installing main bearings?

When installing main bearings, it's critical to ensure the crankshaft journals are clean and within factory specifications. You'll also need to refer to the manufacturer's service manual for proper installation procedures, including torque specifications for the main caps.
