What is the purpose of crankshaft main bearings?

Crankshaft main bearings sit between the crankshaft and the engine block. Their main job is to support the crankshaft, allowing it to rotate smoothly while maintaining the correct oil clearance to reduce friction and wear.

Do I need to check oil clearance when installing these bearings?

Yes, checking oil clearance is a critical step during engine assembly. You'll need a set of Plastigage and a micrometer to ensure the clearance is within the manufacturer's specifications for proper engine function and longevity.

What other parts are typically replaced during an engine bearing job?

When replacing main bearings, it's common practice to also replace connecting rod bearings, piston rings, and gaskets. Inspecting the crankshaft for any damage or wear is also highly recommended.
