What does '0.040 undersize' mean for these bearings?

This means the bearings are manufactured to be 0.040 inches smaller in diameter than standard size. They are intended for use when the crankshaft journals have been machined down by 0.040 inches during an engine rebuild.

What is bimetal construction?

Bimetal construction typically involves a steel backing for strength and a bearing material layer, often aluminum-based, on the surface that contacts the crankshaft. This design helps manage load and reduce friction.

Are these bearings sold individually or as a set?

This product is sold as a set of connecting rod bearings, which is what you would typically need for an engine rebuild.

About this part

Product Details

This kit includes a set of connecting rod bearings for your Austin Apache 1275 GT. These bearings are built with a bimetal construction, featuring an aluminum base, which is a common and effective design for engine components like these. They are specifically sized at 0.040 inches undersize, meaning they are intended for use when the crankshaft journals have been machined down by that amount during an engine rebuild.

King Engine Bearings uses this bimetal approach to balance durability with the necessary performance characteristics for engine internals. This type of bearing is designed to handle the loads and friction encountered in a running engine, helping to ensure smooth operation and longevity for your Austin Apache's powerplant. When you're rebuilding the bottom end of your engine, getting the right bearing size is crucial for proper oil clearance and function.
