What does 'STD' size mean for these main bearings?

STD stands for standard size. This means the bearings are manufactured to the original factory dimensions. They are intended for use when the crankshaft journals are still within their original factory specifications and have not been machined undersize.

What other parts might I need when installing new main bearings?

When replacing main bearings, it's crucial to inspect the crankshaft journals for wear or damage. You'll also need new main bearing cap bolts and potentially new oil seals. Always refer to the service manual for your specific vehicle for a complete list of recommended parts and procedures.

How should I lubricate these bearings during installation?

It's essential to lubricate the new main bearings thoroughly with a quality engine assembly lubricant before installation. This ensures proper oil film formation upon initial startup and prevents metal-to-metal contact. Always follow the specific lubrication and torque specifications outlined in your vehicle's service manual.

About this part

Product Details

Doing an engine rebuild on your 1998-2004 Chrysler Concorde with the 2.7L V6? These ACL crankshaft main bearings are a direct replacement for your stock bearings. They are essential for keeping the crankshaft properly supported and aligned within the engine block, ensuring smooth operation and preventing excessive wear.

ACL has been making engine bearings for a long time, and these are well-built replacements. They are designed to meet the original equipment specifications, so you can be confident they'll fit right and perform as expected. This set is for the standard size (STD), meaning it's intended for crankshafts that are still within their original factory tolerances. If your crankshaft has been machined undersize due to wear or damage, you'll need a different size bearing set.

When you're putting in new main bearings, it's a good idea to also check the condition of your crankshaft journals for any scoring or out-of-roundness. Make sure to follow the manufacturer's lubrication and torque specifications during installation to get the best results from these bearings.
