What does the 0.010 inch undersize mean for these bearings?

The 0.010 inch undersize indicates that these bearings are intended for use on a crankshaft whose main journals have been machined down by 0.010 inches. This is a common practice during engine rebuilding to correct wear or damage on the crankshaft.

What is the advantage of Clevite's multi-layer bearing material?

Clevite's multi-layer construction combines a strong steel backing with a conformable babbit overlay. This design helps the bearing to absorb shock loads, embed small debris particles, and maintain a consistent oil film for better crankshaft protection.

Do these bearings come with new main bolts?

This product is a main bearing set and typically includes only the bearings themselves. Main bearing bolts are usually sold separately, and it is recommended to use new, high-quality bolts when rebuilding an engine.

Product Details

This Clevite main bearing set is built with a 0.010 inch undersize, meaning it's designed to accommodate crankshaft journals that have been machined down by 0.010 inches during an engine rebuild. These bearings are crucial for the health of your Ford 351M, 351W, or 400 V8 engine, providing a smooth, low-friction surface for the crankshaft to rotate within the engine block. When you're rebuilding the bottom end of an engine, especially for these popular Ford V8s, getting the main bearings right is a critical step for ensuring longevity and proper oil pressure.

Clevite uses a multi-layer bearing material construction, combining a steel backing for strength with a babbit overlay for excellent conformability and embeddability. This design helps to absorb shock loads and maintain oil film integrity, even under demanding conditions. This set is specifically sized for crankshafts that have been machined 0.010 inches undersize, a common practice when dealing with wear or damage on the main journals. Proper installation is key, so always refer to the manufacturer's service manual for torque specifications and assembly procedures.

This set fits a wide range of Ford vehicles from 1977 through 1996, including popular models like the F-150, E-150 Econoline, and Bronco. Ensuring you have the correct size bearing for your machined crankshaft is essential for a successful engine rebuild.
