What does a 0.010 inch undersize bearing mean?

An undersize bearing, like this 0.010 inch set, is used when the crankshaft journals have been machined down by that amount. This allows the new bearings to provide the correct oil clearance for the reconditioned crankshaft.

What vehicles does this main bearing set fit?

This Clevite main bearing set is designed for a range of Ford and Mercury vehicles from 1972 to 1992, specifically those equipped with 2.6L, 2.8L, or 2.9L engines. Examples include the Ford Ranger, Bronco II, and Mercury Capri.

What are the symptoms of worn main bearings?

Worn main bearings can lead to a noticeable knocking sound from the bottom of the engine, especially under load. You might also experience fluctuating or low oil pressure readings on your gauge.

Product Details

This main bearing set from Clevite features a 0.010 inch undersize, meaning it's designed to be used when the crankshaft journals have been machined down by 0.010 inches during an engine rebuild. These bearings are crucial for maintaining the proper oil clearance between the crankshaft and the engine block, ensuring smooth operation and preventing metal-on-metal contact. They are built to fit a range of Ford and Mercury vehicles from 1972 to 1992, including popular models like the Ford Ranger, Bronco II, and Mercury Capri.

Clevite uses a multi-layer material construction with a steel backing for strength and a bearing surface designed for durability and proper oil retention. This combination helps to handle the loads placed on the crankshaft while allowing for the thin film of oil that lubricates the rotating assembly. When your engine's main bearings are worn, you might notice increased oil pressure issues or knocking sounds, and replacing them with a set like this is a key step in restoring engine health.

This set is intended for use during an engine overhaul where the crankshaft has been reconditioned to a 0.010 inch undersize. Always refer to your vehicle's specific service manual for detailed installation procedures and torque specifications.
