Clevite Caterpillar 3406 C18 6 Cyl 3408 8-Cyl 3412 12-Cyl Individual Main Bearings

If you're rebuilding the engine in your Caterpillar 3406, C18, 3408, or 3412 series engine, getting the main bearings right is critical. These Clevite main bearings are designed to handle the heavy loads and high operating temperatures these large displacement engines are known for. They sit between the crankshaft and the engine block, supporting the crankshaft and allowing it to spin smoothly.

Clevite uses a multi-layer bearing design that incorporates a steel backing for strength, a bronze interlayer for durability, and a bearing overlay that's engineered to withstand the demands of diesel power. This construction helps to manage heat and reduce friction, which is key to the longevity of your engine. These are individual bearings, meaning you'll order the specific ones you need for your crankshaft journal size during an engine overhaul.
