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 that allows the crankshaft to rotate smoothly at high speeds. Replacing them is essential during engine rebuilds to ensure proper oil clearance and support.

Are these bearings undersized or oversized?

This is a standard size main bearing set. It is intended for use with a crankshaft that has not been machined undersize. Always verify your crankshaft journal dimensions before ordering.

What else might I need when installing these main bearings?

When installing main bearings, it's critical to have a clean work environment and proper tools. You'll need a torque wrench to tighten the main caps to specification, and it's highly recommended to use assembly lube on the bearings and crankshaft journals to protect them during initial startup.

Product Details

This is a Clevite Main Bearing Set, part number MS1039H, designed for Ford 370, 429, and 460 cubic inch V8 engines built between 1968 and 1994. These bearings are a crucial part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. When rebuilding or refreshing an engine from this era, especially in popular Ford trucks and full-size cars like the F-250, E-350 Econoline, or Gran Torino, replacing the main bearings is a standard and important step.

Clevite is known for making well-built engine components, and this main bearing set is no exception. They are manufactured to meet the specific tolerances required for these large displacement Ford V8s. Proper installation is key, as these bearings sit directly against the crankshaft and within the main caps. Ensuring the crankshaft journals are clean and within spec, and that the correct torque is applied to the main caps, will help these bearings perform as intended for many miles to come.
