What is the main function of crankshaft main bearings?

Crankshaft main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining precise oil clearance.

When should I consider replacing my main bearings?

Main bearings should always be replaced during an engine rebuild or overhaul. Signs of wear include knocking or rumbling noises from the engine, low oil pressure, or excessive crankshaft end play.

Does this bearing set include all the necessary main bearings for my engine?

Product Details

When you're rebuilding a 4.0L V6 engine in your Ford Ranger, Explorer, or Mercury Mountaineer, the crankshaft main bearings are critical. These ACL main bearings, part number 4M2006A-10, are built to handle the stresses of daily driving and more demanding use. They are designed to provide a solid foundation for your crankshaft, ensuring smooth rotation and proper oil clearance.

ACL uses a specialized overlay material that's well-built for durability and wear resistance. This means they can stand up to the heat and friction generated during engine operation. Proper installation is key here; making sure the crankshaft journals are clean and within spec, and that you're using the correct oil weight, will help these bearings last a long time. If you're doing a full engine overhaul, replacing these bearings is a necessary step to ensure the longevity and performance of your engine.

This set includes the main bearings needed for your engine. Always refer to your vehicle's service manual for the exact installation procedure and specifications.
