What does '0.020 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.020 inches smaller in diameter than the standard size. This is typically done when the crankshaft journals have been machined down (ground) to remove wear or damage. You must use these bearings only if your crankshaft has been machined to this specific undersize.

Do these bearings come with thrust washers?

No, this set is optional to the MB431SI and requires separate thrust washers. You will need to source those independently if your engine requires them.

What is the material of these main bearings?

These bearings are made from a bimetal material with an aluminum silicon base. This construction is chosen for its good wear characteristics and ability to handle engine loads.

Product Details

If you're rebuilding the bottom end of your Ford Taunus V6, or another compatible vehicle like a Ford Ranger or Mercury Capri, a fresh set of main bearings is crucial. These bearings sit between your crankshaft and the engine block, allowing the crank to spin smoothly while handling the immense forces generated during combustion. Getting this part right is key to a healthy, long-lasting engine.

This main bearing set from King Engine Bearings uses a bimetal construction with an aluminum silicon base. This material choice is well-suited for the demands of a V6 engine, offering good wear resistance and load-carrying capacity. The set includes four main bearings, and they are sized at 0.020 inches undersize, which is important to note if you're machining your crankshaft. This set is an optional upgrade to the MB431SI, requiring separate thrust washers.

When you're putting an engine back together, using well-built components like these bearings can make a significant difference. Ensure you consult your vehicle's service manual for proper installation procedures and any specific requirements for your build.
