What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are 0.25mm larger in diameter than a standard-sized bearing. This is used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to ensure a proper fit and oil clearance.

What is the construction of these main bearings?

These bearings feature a bimetal construction, utilizing an aluminum base. This type of material is chosen for its good heat transfer properties and compatibility with the rotating crankshaft.

Do these bearings come with installation hardware?

This product is for the main bearing set only. Installation hardware, such as main bearing bolts, is typically sold separately and should be replaced during an engine rebuild.

About this part

Product Details

If you're rebuilding the engine in your Volvo 960, S60, S80, S90, V60, V90, XC60, or XC70, these King Engine Bearings main bearing set (part number MB7023AM0.25) are a solid option. These are main bearings, which support the crankshaft within the engine block, ensuring it spins smoothly and stays properly aligned. This set is specifically sized at +0.25mm, meaning they are 0.25mm larger than standard, which is crucial if your crankshaft has been machined to that size during an overhaul.

King uses a bimetal construction with an aluminum base for these bearings. This design helps manage heat and provides a good surface for the crankshaft to rotate against. Because these are a specific size (+0.25mm), it's important to confirm that your crankshaft has been machined to match this size. If your crankshaft is still at standard size, you'll need a standard-sized bearing set.
