What does the 0.010 inch undersize mean for my engine?

The 0.010 inch undersize indicates that these bearings are intended for a crankshaft that has been machined down by 0.010 inches from its original size. This is a common practice when a crankshaft has wear and needs to be reconditioned to be used again.

What is the tri-metal overlay construction?

ACL uses a tri-metal overlay, which is a layered material designed for high performance. This construction offers excellent durability, good embeddability for small debris, and the ability to maintain a strong oil film under pressure, helping to protect the bearing surfaces.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit, it is always recommended to refer to the manufacturer's installation instructions or a reputable service manual for the correct procedures. Proper installation, including cleaning and oiling, is crucial for engine longevity.

Product Details

When you're rebuilding a Ford 370, 429, or 460 engine, the connecting rod bearings are critical for smooth operation and longevity. This set from ACL is built with a 0.010 inch undersize, meaning it's designed to fit crankshafts that have been machined down to compensate for wear. This is a common requirement for engines that have seen significant mileage or are undergoing a performance rebuild where the crankshaft has been reconditioned.

ACL uses a specialized tri-metal overlay on these bearings, which is a well-known material for its ability to handle high loads and maintain oil film integrity. This construction helps reduce friction and wear, even under demanding conditions. The bearings are also designed to fit right into the connecting rods and crank journals for a straightforward installation process, assuming the crankshaft has been properly prepared to the correct undersize specification.

This set is a solid option for many Ford and Lincoln vehicles from the late 60s and early 70s. If you're working on a Ford Country Sedan, Galaxie 500, LTD, Lincoln Continental, or even a Mustang from these years, and your crankshaft has been turned 0.010 inches undersize, these ACL bearings will be the right choice to get your engine back in reliable running order.
