What does a crankshaft main bearing do?

Crankshaft main bearings are crucial for engine operation. They are located between the crankshaft and the engine block, allowing the crankshaft to rotate smoothly while supporting the significant loads generated during combustion and power delivery.

What does the '.75' in the part number mean?

The '.75' in the part number 4M7182A-.75 indicates that these are a .75 undersize bearing set. This means they are designed for use when a crankshaft has been machined down by 0.075 inches to correct for wear or damage.

What condition should the crankshaft be in before installing these bearings?

Before installing new main bearings, it's essential that the crankshaft journals are clean and free from debris. They should also be within the manufacturer's specified tolerances for roundness and straightness. Always consult your vehicle's service manual for detailed preparation steps.

About this part

Product Details

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your Chrysler Concorde is one of their staples. If you're rebuilding the engine in your 1998-2004 Concorde with a 3.2L or 3.5L V6, these bearings are a critical component. They sit between the crankshaft and the engine block, allowing the crankshaft to spin smoothly while supporting the engine's load.

This set is specifically made for the Chrysler SOHC engines found in your vehicle, covering VINs J, 4, G, K, M, and V. They are built with materials suited for the demands of engine operation, helping to ensure proper oil clearance and reduce friction. When you're doing an engine rebuild, getting the right bearing size is key, and this set is designed to fit correctly.

For a successful engine rebuild, it's important to ensure the crankshaft journals are clean and within factory specifications before installing these bearings. Always refer to your vehicle's service manual for the complete installation procedure and any required torque specifications.
