What is the construction of these Clevite main bearings?

These main bearings feature a tri-metal construction. This design is known for providing a good balance between strength and the ability to conform to the crankshaft surface, which is important for proper oil film formation and bearing support.

What is the main purpose 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 they are crucial for maintaining proper oil clearance.

What should I do before installing these main bearings?

Before installation, ensure the crankshaft journals are thoroughly cleaned and inspected for any damage or wear. It's also critical to follow the manufacturer's specified torque values and procedures for installation to ensure proper bearing crush and alignment.
