What does the +0.75mm size 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. This is typically done to correct wear on the original crankshaft or to achieve specific tolerances during an engine rebuild.

What is the MC overlay on these bearings?

The MC overlay is a multi-layer coating applied by King Engine Bearings. This advanced coating is designed to reduce friction between the bearing and the crankshaft, which helps to improve durability and engine performance.

Are these bearings a direct replacement for the original Toyota bearings?

These bearings are a direct replacement in terms of fit and function for the Toyota 3Ur-Fe engine, provided the crankshaft has been machined to the specified +0.75mm size. Always consult your engine's service manual for proper installation procedures.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and this Main Bearing Set for the Toyota 3Ur-Fe engine is no exception. If you're rebuilding the bottom end of your 3Ur-Fe, these bearings are a critical part of ensuring your crankshaft spins smoothly and stays properly aligned within the engine block. They handle the immense forces generated during combustion and power delivery, so having a well-made set is key to a healthy engine.

This set is specifically sized at +0.75mm, meaning it's intended for use with a crankshaft that has been machined down by 0.75mm to account for wear or to achieve a specific build tolerance. The MC designation in the part number indicates King's high-performance overlay, which is a multi-layer coating designed to reduce friction and improve durability. This coating helps the bearings withstand the rigors of engine operation, especially in builds where performance is a priority.
