What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.75mm from its original size. This is common when rebuilding an engine with a worn or damaged crankshaft.

What is King's Machined Overlay (MC) technology?

King's Machined Overlay (MC) technology refers to their high-performance bearing surface material. It's designed to be durable and conform well to the crankshaft, helping to maintain proper oil clearance and reduce wear.

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 is a set of King Engine Bearings connecting rod bearings for Toyota 3UR-FE engines, specifically sized at +0.75mm. These bearings are a crucial part of your engine's rotating assembly, helping to reduce friction and wear between the connecting rod and the crankshaft. When rebuilding or repairing an engine, especially if the crankshaft has been machined, using the correct size bearings is essential for proper oil clearance and long-term engine health.

King Engine Bearings uses a high-performance overlay material that is designed to handle the demands of modern engines. The "MC" in the part number indicates their "Machined Overlay" technology, which is known for its durability and ability to conform to the crankshaft surface. This particular set is machined to a +0.75mm size, meaning it's intended for use when the crankshaft journals have been ground down by 0.75mm from their original size. Ensuring you have the correct bearing size is critical for establishing the proper oil film and preventing metal-to-metal contact, which can lead to catastrophic engine failure.
