What does the +0.75mm size mean for my engine?

The +0.75mm size indicates that these bearings are intended for a crankshaft that has been machined down by 0.75mm. This is typically done to correct for wear or damage on the crankshaft journals during an engine rebuild.

What is the main benefit of a bimetal bearing construction?

Bimetal bearings, like these from King Engine Bearings, use a combination of materials, often a steel backing with a softer overlay like aluminum silicon. This construction offers good wear resistance and the ability to conform to the crankshaft journal, which helps maintain proper oil clearance and reduce friction.

Do these bearings come with installation instructions?

While installation instructions are not included with this bearing set, it is highly recommended to refer to the vehicle manufacturer's service manual or consult a professional mechanic for proper installation procedures and torque specifications.

About this part

Product Details

If you're rebuilding the engine in your Ford 4.6L V8, a fresh set of main bearings is critical for proper oil pressure and crankshaft support. This set from King Engine Bearings is built with a bimetal aluminum silicon base, a well-built material that handles the demands of the rotating assembly. These bearings are sized +0.75mm, meaning they are intended for use with a crankshaft that has been machined to a 0.75mm undersize to correct for wear or damage.

King Engine Bearings is a popular name in engine components, and this set is designed to fit a wide range of Ford vehicles, including popular models like the Ford F-150, Ford Mustang, and Ford Expedition. The bimetal construction offers good wear resistance and conforms well to the crankshaft journal, helping to maintain consistent oil clearance. This is important for ensuring your engine runs smoothly and reliably after the rebuild.
