What does '0.010 inch undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.010 inches. This is common when rebuilding an engine to clean up worn or damaged crank journals.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear, allowing the crankshaft to spin smoothly within the connecting rods under high pressure.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, a set includes enough bearings for all the connecting rods in the engine, which is usually 6 bearings for the inline-six engines this part fits.

About this part

Product Details

Already running a rebuilt or performance engine in your classic Chevrolet? This connecting rod bearing set from ACL is a crucial piece for ensuring smooth operation and longevity. These bearings sit between the connecting rod and the crankshaft, allowing the rod to spin freely while handling the immense forces generated during combustion. For engines like the 194, 230, or 250ci inline-six, getting the right bearings is key to preventing premature wear and potential engine failure.

ACL has been making engine bearings for a long time, and this set is built to handle the demands of these classic engines. They're made with a multi-layer material that balances strength and friction reduction, which is exactly what you need for reliable performance. When you're rebuilding an engine or replacing worn parts, using well-built bearings like these helps ensure your engine runs right for miles to come. This particular set is sized at 0.010 inches undersize, meaning it's designed to fit a crankshaft that has been machined down by that amount to clean up any imperfections or wear.

When installing these bearings, make sure your crankshaft journals are clean and within the specified tolerance for the 0.010 undersize. It's always a good idea to check the manufacturer's installation instructions for proper oil clearance and any specific break-in procedures.
