What does 'undersize' mean for these bearings?

An undersize bearing, like this 0.020 inch set, is used when the crankshaft has been machined down to remove wear or damage. The bearing is made slightly smaller to compensate for the material removed from the crankshaft journals.

What is the main function of crankshaft main bearings?

Crankshaft main bearings are crucial components that sit between the crankshaft and the engine block. They support the crankshaft's rotation, reduce friction, and help maintain precise alignment of the crankshaft within the engine.

Do I need to measure my crankshaft before ordering these bearings?

Yes, it's essential to measure your crankshaft journals to confirm the correct size. If your crankshaft has been machined, you'll need to know the exact undersize (e.g., 0.020 inches) to order the correct bearings.

These ACL bearings are made for your 1985-1996 Ford Escort with the 1.9L 4-cylinder engine.
