What is the purpose of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear in this critical area, allowing the crankshaft to spin smoothly within the engine block.

Why are these bearings 0.00075 inches undersize?

The bearings are undersize to accommodate crankshaft journals that have been machined down, typically during a previous engine rebuild or repair. This ensures a proper fit and clearance on a slightly smaller journal diameter.

What else might I need when installing these bearings?

When installing connecting rod bearings, you'll need to follow the manufacturer's service manual for proper torque specifications and procedures. It's also crucial to ensure the crankshaft journals are clean and within acceptable wear limits before installation.

About this part

Product Details

ACL has been making engine bearings for decades, and this connecting rod bearing set for your Ford Crown Victoria is one of their staples. These bearings are a critical part of your engine's rotating assembly, sitting between the connecting rod and the crankshaft. They help reduce friction and wear, ensuring smooth operation and longevity for your 4.6L or 5.4L V8 engine.

This particular set is built to the original equipment specifications, meaning they'll fit right in place of your stock bearings. They are made from a durable tri-metal material that offers good wear resistance and conformability, which is important for maintaining oil film and preventing damage under load. The set includes bearings that are 0.00075 inches undersize, which is useful if your crankshaft journals have been ground down slightly during a previous rebuild or repair. Always check your crankshaft journal dimensions to ensure proper fitment with undersize bearings.

When you're rebuilding an engine or addressing bottom-end noise, replacing the connecting rod bearings is a key step. Make sure you have the correct torque wrench and follow the manufacturer's service manual for proper installation procedures, including checking bearing clearances and ensuring the crankshaft is clean before assembly.
