What is the main function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on and help maintain consistent oil pressure throughout the engine's lubrication system.

What does 'tri-metal construction' mean for these bearings?

Tri-metal construction refers to the bearing's layered design, typically including a steel backing for strength, a middle layer for load carrying, and a soft overlay for embeddability and wear resistance. This combination offers excellent durability and performance under demanding conditions.

Do these bearings come with installation hardware?

This listing is for the main bearing set only. Installation hardware, such as main bearing bolts, is typically sold separately. Always refer to the manufacturer's instructions for a complete list of required components.

About this part

Product Details

This Clevite MS2249A10 main bearing set is built with a tri-metal construction, featuring a steel-backed overlay with a lead-tin-copper overlay. This advanced material composition is designed to handle the high loads and temperatures found in your engine's main journals, ensuring the crankshaft spins smoothly and stays properly aligned. When you're rebuilding your engine or addressing wear in the bottom end, a solid set of main bearings is crucial for maintaining oil pressure and preventing premature wear on other components.

These bearings are specifically made to fit the 2.8L and 2.9L DOHC engines found in the 2004-2012 Chevrolet Colorado, 2004-2012 GMC Canyon, 2006 Isuzu i-280, and 2007-2008 Isuzu i-290. The tri-metal design offers improved embeddability and conformability, meaning they can adapt to minor imperfections in the crankshaft journal while providing a durable surface. This helps to maintain consistent oil film thickness, which is vital for reducing friction and heat.

Installing a new set of main bearings is a key step in any engine overhaul. It ensures the crankshaft has a solid foundation to rotate within, which directly impacts engine performance and longevity. Make sure to follow the manufacturer's installation instructions carefully, including proper cleaning of the crankshaft and block surfaces, and using the correct torque specifications.
