What is the purpose of main bearings in an engine?

Main bearings are critical components that sit between the crankshaft and the engine block. They support the crankshaft, allowing it to rotate smoothly while handling the significant forces generated during combustion.

What is the significance of Clevite as a brand for engine bearings?

Clevite is a well-known manufacturer of engine components. Their bearings are generally considered well-built and are often chosen by mechanics and engine builders for their reliability and performance in demanding applications.

What should I check before installing these main bearings?

Before installing, it's important to inspect your crankshaft journals for any damage or wear. You should also verify the correct oil clearance using a micrometer and Plastigage, ensuring it meets the manufacturer's specifications for your specific engine model.

Product Details

If you're rebuilding the bottom end of a Caterpillar engine, specifically a C10, C11, or C12 model, these individual main bearings from Clevite are what you'll need. They are designed to sit between the crankshaft and the engine block, allowing the crankshaft to spin smoothly while supporting its weight and the forces acting upon it.

Clevite is known for making well-built engine components, and these bearings are no exception. They are made to handle the demanding environment inside an engine, helping to ensure proper oil clearance and reduce friction. This is crucial for the longevity and performance of your engine, especially after a rebuild where everything needs to be set up just right.
