What is the purpose of connecting rod bearings?

Connecting rod bearings are crucial components that sit between the connecting rod and the crankshaft. They allow the connecting rod to rotate smoothly around the crankshaft while maintaining a precise oil gap to lubricate the surfaces.

What does '1.00mm undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 1.00mm. This is typically done when a crankshaft is worn or damaged and needs to be resurfaced to a smaller diameter.

Do I need to measure my crankshaft before ordering?

Yes, it is highly recommended to measure your crankshaft journals. This ensures you order the correct bearing size, whether it's standard or an undersize like the 1.00mm offered here, to achieve the proper oil clearance.

Product Details

Connecting rod bearings are critical for your engine's health. They sit between the connecting rod and the crankshaft, allowing the rod to spin smoothly while maintaining a precise oil gap. When these bearings wear down, that oil gap increases, leading to excessive play, knocking noises, and eventually, catastrophic engine failure. This set from ACL is made to the correct specifications to restore that vital oil clearance.

This set is specifically sized at 1.00mm undersize, meaning it's designed for crankshafts that have been machined down by 1.00mm due to wear or damage. It's important to measure your crankshaft journals to confirm this is the correct size needed for your rebuild.
