What does 'standard' mean for these main bearings?

Standard size bearings are meant to be installed when the crankshaft journals are still within their original factory specifications. If your crankshaft has been machined undersize due to wear or damage, you would need an undersize bearing set.

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

Installing main bearings typically requires engine disassembly and reassembly. While the bearings themselves are a direct fit, you'll need standard engine rebuilding tools, including torque wrenches and potentially a bearing installation tool. Always refer to the manufacturer's installation instructions for specific details.

What other parts should I consider replacing when installing main bearings?

When rebuilding an engine and replacing main bearings, it's a good time to also replace connecting rod bearings, piston rings, and check the condition of the crankshaft itself. Inspecting and replacing seals and gaskets is also recommended for a complete engine overhaul.

About this part

Product Details

When you're rebuilding a worn-out 4.0 liter engine in your 1991-1996 Jeep Cherokee, Comanche, Grand Cherokee, or Wrangler, replacing the main bearings is a critical step.

This complete set includes all the necessary bearings for your engine's standard crankshaft. Omix is known for providing well-built replacement parts that help you get the job done right.

This set is designed to fit right, making the installation process as straightforward as possible when you're already deep into an engine overhaul.
