What does '.010 Over' mean for these main bearings?

The '.010 Over' designation means these bearings are 0.010 inches larger than standard size. This indicates they are intended for use with a crankshaft that has been machined down by 0.010 inches during an engine rebuild to account for wear.

Do I need any special tools to install these main bearings?

Installing main bearings is part of a larger engine rebuild process. While the bearings themselves don't require special tools for installation, you will need engine-specific tools for crankshaft removal, machining verification, and reassembly.

Product Details

When you're rebuilding an engine, especially in a Jeep where every bit of power counts, replacing worn internal components is key. This Omix main bearing set is designed to be 0.010 inches undersize, meaning it's meant for crankshafts that have been machined down to that specific size during the rebuilding process. These bearings sit between the crankshaft and the engine block, allowing the crank to spin smoothly while supporting the engine's weight.

This set includes all the main bearings needed for a complete engine rebuild on a range of Jeep models from 1972 through 1991, specifically those equipped with the 5.0L and 5.9L engines. Using bearings that are the correct size for your machined crankshaft is crucial for proper oil clearance, which ensures the engine runs efficiently and lasts. Omix offers these replacement parts to help you get your Jeep's engine back to its original performance levels after significant wear.

Installing these bearings is part of a larger engine overhaul. It's important to ensure your crankshaft journals have been properly machined to the 0.010-inch undersize specification before installation. This set is backed by a limited 5-year warranty from Omix.
