What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining precise oil clearance, which is essential for lubrication and preventing wear.

Are these bearings sold as a set or individually?

These are individual main bearings. You will need to purchase the correct quantity for your specific Caterpillar 6C9 engine application to replace all necessary main bearings.

What is important to know before installing these bearings?

Proper installation is crucial for the longevity of these bearings. Always ensure the crankshaft and bearing surfaces are clean, and adhere strictly to the manufacturer's recommended oil clearance specifications.
