What is the main function of crankshaft main bearings?

Crankshaft main bearings are crucial for engine operation. They support the crankshaft within the engine block, allowing it to rotate smoothly while handling the significant forces from combustion. Proper functioning of these bearings is essential for maintaining oil pressure and preventing premature engine wear.

What engine displacements are covered by this ACL bearing set?

This ACL bearing set is designed for Ford V8 engines with displacements of 255, 289, and 302 cubic inches. These are common engine sizes found in many classic Ford and Mercury vehicles.

Are these bearings a direct replacement for the original Omega Omega engine?

Yes, this ACL crankshaft main bearing set is designed as a direct fit replacement for the specified 1967-1968 Omega Omega models equipped with the compatible Ford V8 engines. Installation requires the engine to be disassembled.

About this part

Product Details

Already rebuilt the engine or looking to do a full refresh on your 1967-1968 Omega Omega? This ACL crankshaft main bearing set is a critical component for any V8 build using Ford 255, 289, or 302 engines. These bearings sit between the crankshaft and the engine block, allowing the crank to spin smoothly while supporting the immense forces generated during combustion. Replacing them is a key step when you've got the engine apart to ensure long-term reliability and proper oil pressure.

ACL has been making engine bearings for a long time, and this set is built to handle the demands of these classic Ford V8s. They're made with a specific overlay material that's designed to work well with the crankshaft journals, helping to maintain oil film and reduce friction. When you're putting an engine back together, especially one that's going to see regular use, you want parts you can trust to keep things running right for miles to come.
