What does the '0.020 inch undersize' mean for these bearings?

This indicates the bearings are designed to fit crankshaft journals that have been machined down by 0.020 inches. This is common during engine rebuilds when the crankshaft needs to be resurfaced due to wear or damage.

Are these bearings sold individually or as a set?

This part number, CB1806A20(6), represents a set of connecting rod bearings. Typically, a set includes enough bearings for all the connecting rods in the engine.

What is the typical lifespan of these bearings?

The lifespan of connecting rod bearings depends heavily on proper installation, consistent oil changes with the correct oil type and viscosity, and the overall condition of the engine. Clevite bearings are well-regarded for their durability when installed correctly.

About this part

Product Details

These Clevite connecting rod bearings are built with a 0.020 inch undersize, making them a solid choice when you're rebuilding an engine and need to machine the crankshaft journals. They are designed to fit a wide range of Buick V6 engines, including popular models like the Regal, LeSabre, and Park Avenue, as well as many Chevrolet, Oldsmobile, and Pontiac applications from the early 90s through the late 2000s.

Clevite uses a multi-layer bearing material that helps manage oil flow and reduce friction, which is crucial for the longevity of your engine's rotating assembly. The specific alloy composition is chosen to provide good wear resistance and conformability to the crankshaft surface. When installing these bearings, it's important to ensure the crankshaft journals are clean and within the specified tolerance for the 0.020 inch undersize to achieve proper oil clearance and performance.
