What is the difference between standard and undersize bearings?

Standard size bearings are meant to be installed when the crankshaft journals are in good condition and within factory specifications. Undersize bearings are used when the crankshaft journals have been machined down to remove damage or wear.

Do I need to machine my crankshaft to install these bearings?

No, these are standard size bearings. They are designed to fit the original crankshaft journals without requiring any machining. Always check your crankshaft for straightness and damage before installation.

What else might I need when replacing connecting rod bearings?

When replacing connecting rod bearings, it's highly recommended to also replace the main bearings, oil pump, oil filter, and engine oil. Inspect the connecting rods and crankshaft for any signs of damage or wear.

About this part

Product Details

You get a full set of connecting rod bearings in this kit, which means one box handles the whole engine rebuild or repair. These ACL bearings are made specifically for the 2.0L Duratec engine found in the 2005 Ford Focus. They are a standard size, meaning they're meant to replace your original bearings without needing any machine work on the crankshaft.

Properly functioning connecting rod bearings are crucial for keeping your engine running smoothly. They create a thin film of oil between the connecting rod and the crankshaft, preventing metal-on-metal contact and reducing wear. If your engine is making knocking noises or you're doing a full rebuild, replacing these bearings is a key step to ensure longevity and performance. ACL is a well-known name in engine bearings, and this set is a solid option for getting your Focus back on the road.
