What does '0.030 inches undersize' mean for these bearings?

This means the bearings are manufactured to be 0.030 inches smaller in diameter than the standard size. This is typically used when the crankshaft journals have been machined down by 0.030 inches to remove wear or damage.

What is the typical application for this bearing set?

Product Details

If you're rebuilding the bottom end of your engine, a solid set of main bearings is crucial for smooth operation and long life. This Clevite Main Bearing Set, part number MS1733P30, is designed to fit a wide variety of American vehicles from the late 70s through the early 90s, including popular models like the Chevrolet S10, Pontiac Firebird, and Buick Century.

These bearings are built with a multi-layer material that includes a steel backing for strength, a copper-lead overlay for improved embeddability, and a thin overlay for added durability. This construction helps them handle the pressures and heat generated within the engine's crankcase, ensuring the crankshaft spins true and without excessive wear. They are precisely sized at 0.030 inches undersize, which is important to note if you are machining your crankshaft to match.

When installing these bearings, it's always a good idea to refer to the manufacturer's service manual for the correct torque specifications and any specific preparation steps required for your engine. Proper installation is key to getting the most out of these well-built components.
