What does it mean that these bearings are undersize 0.010 inch?

This means the bearings are manufactured to be 0.010 inches smaller in diameter than the standard size. This is necessary when the engine's crankshaft has been machined down by 0.010 inches to remove wear or damage. Using the correct undersize bearing ensures proper oil clearance for the crankshaft.

About this part

Product Details

This ACL main bearing set is built for Ford V6 engines, specifically the 3.8L (232ci) and 4.2L (256ci) found in many 1982 and later models. Main bearings are critical for keeping your crankshaft spinning smoothly within the engine block. When they wear out, you can get excessive bearing noise, oil pressure loss, and eventually, serious engine damage. This set is undersized by 0.010 inches, which is important if you've had your crankshaft machined to a similar undersize to clean up wear or damage. Using the correct undersize bearing ensures a proper oil clearance, which is key for engine longevity.

This set includes the main bearings needed for your Ford V6. Always refer to your vehicle's service manual for the correct installation procedures and torque specifications.
