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

Main bearings sit between the engine block and the crankshaft. Their primary job is to support the crankshaft, allowing it to rotate smoothly while maintaining the correct oil clearance.

Do I need to replace the crankshaft when installing new main bearings?

Not necessarily. New main bearings are typically installed when the original bearings show wear or during a performance build. You should inspect your crankshaft for any damage or excessive wear before installing new bearings.

What else might I need when installing main bearings?

When replacing main bearings, it's highly recommended to also replace the connecting rod bearings. You'll also need a good quality engine assembly lube to properly coat the bearings and crankshaft journals before installation.
