What is the purpose of crankshaft main bearings?

Crankshaft main bearings sit between the crankshaft and the engine block. Their main job is to reduce friction as the crankshaft spins and to support the crankshaft's weight and the forces acting upon it during engine operation.

Are these bearings a direct fit for my 1970 Ford Country Sedan?

Yes, this ACL 5M1039A-10 main bearing set is specifically designed to fit the 1969-1973 Ford Country Sedan with the specified V8 engines. Always confirm your engine size matches the application.

What else might I need when installing new main bearings?

When installing new main bearings, it's critical to ensure the crankshaft journals and bearing bores in the block are clean and within specified tolerances. You'll also need assembly lubricant to protect the bearings during initial startup. Refer to your vehicle's service manual for detailed installation procedures and torque specifications.
