What is the main function of crankshaft main bearings?

Crankshaft main bearings sit between the crankshaft and the engine block. Their primary job is to reduce friction and support the crankshaft as it rotates, preventing excessive wear on both components.

Do I need to measure my crankshaft journals when installing these bearings?

Yes, it's highly recommended. You should always check that your crankshaft journals are clean, smooth, and within the manufacturer's specified diameter and roundness before installing new bearings.

Does this bearing set come with assembly lube?

This set includes the main bearings themselves. You will need to purchase a suitable engine assembly lubricant separately to properly coat the bearings and journals before installation.
