What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a precise clearance that allows the crankshaft to rotate smoothly while maintaining a film of oil for lubrication and to prevent direct metal-to-metal contact.

Does this set include upper bearing shells?

No, this set specifically includes only the lower bearing shells. You will need to use the upper shells from your existing set or a compatible replacement set to complete the main bearing installation.

What is the typical installation process for these bearings?

These bearings are designed to fit into the factory main bearing saddles in the engine block. Installation involves cleaning the block and crankshaft thoroughly, placing the bearings, and then torquing the main caps according to the manufacturer's specifications. Always consult your service manual for detailed instructions.

Product Details

If you're rebuilding the bottom end of your Chrysler 383, 426, or 440 V8 engine from 1959 through 1973, these Clevite main bearings are a solid option. They are designed to replace the lower shells of your existing main bearing set, providing a crucial interface between the crankshaft and the engine block. Proper bearing clearance is essential for oil flow and to prevent metal-on-metal contact, which can quickly lead to catastrophic engine failure.

This set includes nine lower shells, which is the standard quantity for a V8 engine of this era. Clevite is known for producing well-built engine components, and these bearings are made with materials and manufacturing processes aimed at providing reliable performance for your rebuild. They are designed to fit right into the factory bearing saddles, making installation straightforward for a mechanic familiar with engine assembly.

When assembling your engine, always ensure you have the correct oil clearance by measuring your crankshaft journals and the inside diameter of the bearing saddles. These bearings are intended to be used with the upper shells from your existing set or a compatible replacement set to achieve the proper specification. Always refer to your vehicle's factory service manual for detailed assembly procedures and torque specifications.
