What does it mean that these bearings are 0.25mm oversized?

This means the bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.25mm to correct for wear. This allows for a proper fit and oil clearance in a rebuilt or repaired engine.

What is the benefit of using ACL rod bearings?

ACL is a popular manufacturer of engine bearings. Using their performance rod bearings helps to ensure reduced friction and proper oil clearance, which is crucial for the health and longevity of your engine.

Do I need to have my crankshaft machined for these bearings?

Yes, because these bearings are 0.25mm oversized, your crankshaft journals will need to be machined to match this size. It's recommended to consult with a professional machine shop to ensure correct measurements and preparation.

About this part

Product Details

This ACL rod bearing set is built for the W11B16 Tritec engine found in the 2002-2008 Mini Cooper. Rod bearings are critical for reducing friction between the connecting rod and the crankshaft. When they wear out, you can experience increased engine noise, reduced oil pressure, and potential engine damage. This set is .25mm oversized, meaning it's designed to be used when the crankshaft journals have been machined down to account for wear. This allows for a fresh, tight fit, restoring proper clearances and helping to ensure the longevity of your engine.

ACL is a well-known name in engine bearings, and this set is a solid option for rebuilding or refreshing your Mini Cooper's engine. Make sure to check your crankshaft journal dimensions and consult with your machine shop to confirm these are the correct size for your rebuild project.
