What does the .50mm undersize mean for these bearings?

The .50mm undersize specification means these bearings are designed to fit a crankshaft that has been machined down by 0.50mm (approximately 0.020 inches). This is common when rebuilding an engine with a worn or damaged crankshaft.

What is the benefit of using ACL main bearings?

ACL is a popular brand known for producing reliable engine bearings. Using their well-built bearings helps ensure proper oil clearance and pressure, which is essential for the longevity and performance of your engine.

Do I need to measure my crankshaft before ordering?

Yes, it's highly recommended. You should measure your crankshaft journals to confirm they have been ground to a 0.50mm undersize. This ensures you order the correct size bearing set for your engine rebuild.

About this part

Product Details

This ACL main bearing set is built for the Ford/Cosworth 2.0L YB engine, commonly found in the 1971-1974 Ford Pinto and Mercury Capri. When your engine's main bearings wear down, they can cause excessive clearance between the crankshaft and the engine block. This leads to reduced oil pressure, increased engine noise, and can eventually cause catastrophic engine failure. This set is precisely machined to be 0.50mm undersize, meaning it's designed to be used when the crankshaft has been ground down by 0.50mm to correct for wear or damage. Using the correct undersize bearing ensures a proper fit and optimal oil clearance, which is crucial for engine longevity and performance.

ACL is a well-known name in engine bearings, and this set is a solid option for rebuilding or repairing your 2.0L YB engine. They are made to meet the demands of performance applications, ensuring they can handle the stresses of regular driving and more spirited use. Make sure to check your crankshaft's actual measured size before ordering to confirm you need the 0.50mm undersize set.
