What does the 0.001" undersize mean for my engine build?

The 0.001 inch (0.025mm) undersize indicates that these bearings are slightly smaller than standard size. This is necessary if the crankshaft journals have been machined down during a previous rebuild or repair to ensure proper oil clearance and fit.

What specific Ford engines are these bearings for?

These bearings are designed for Ford BD series engines, including variants like the BDA, BDB, BDC, and BDD. They are commonly found in performance applications for the 1099cc to 1700cc displacement range.

Are these bearings suitable for a stock engine rebuild?

While these are high-performance bearings, they can be used in a stock rebuild if the crankshaft journals have been machined to the 0.001" undersize specification. For a completely stock, unmachined crankshaft, you would typically need standard size bearings.

Product Details

Rebuilding the top end of your 1962-1965 Ford Capri's BD Cosworth engine? This ACL Connecting Rod Bearing Set is a crucial piece for ensuring smooth operation and longevity. These bearings sit between the connecting rod and the crankshaft, allowing the rod to rotate freely while handling immense forces. This set is specifically designed for the 1099-1700cc displacement range common in these performance engines.

This set features a 0.001 inch (0.025mm) undersize, which is important if your crankshaft journals have been machined down during a previous rebuild or repair. ACL is known for making well-built engine components, and these high-performance bearings are no exception. They are built to handle the increased stresses found in performance applications, helping to maintain proper oil clearance and reduce friction under demanding conditions.

When you're putting an engine back together, especially a performance build like a Cosworth BD series, using the right internal components is key. This set is designed to fit the Ford Capri models from 1962 through 1965, ensuring you get the correct dimensions for your specific application.
