What does the '+0.75' size mean for these bearings?

The '+0.75' indicates that these bearings are 0.75mm larger in diameter than standard size. They are designed for use when the engine's crankshaft has been machined down by 0.75mm during a rebuild to correct wear or damage.

What is the construction of these main bearings?

These main bearings are constructed with a bimetal design, featuring an aluminum base. This type of construction is common for engine bearings due to its good load-carrying capacity and compatibility with crankshaft surfaces.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary bearings to replace the main bearings for the specified engine. You will receive multiple bearings as part of this kit.

About this part

Product Details

King Engine Bearings is well-known for making solid engine bearings. This main bearing set is built for a range of Infiniti and Nissan vehicles, including the J30, 300ZX, and Maxima, using the 181 cubic inch 3.0L VG30DE/TT V6 or the 122 cubic inch 2.0L VG20DET V6 engines.

This set features a bimetal construction with an aluminum base, which is a common and reliable material for main bearings. These bearings are sized at +0.75mm, meaning they are meant for crankshafts that have been machined down by that amount during an engine rebuild. Using the correct size bearing is crucial for maintaining proper oil clearance and ensuring the crankshaft spins freely within the engine block.
