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

The +0.75mm designation indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.75mm. This is a common practice during engine rebuilding to remove wear or damage from the crankshaft surface.

What is the advantage of a bimetal bearing construction?

Bimetal bearings, like these from King Engine Bearings, use an aluminum base. This construction offers good thermal conductivity to help dissipate heat away from the bearing surface and the crankshaft, along with solid wear resistance for long-term engine operation.

Are these bearings a direct replacement for all Volvo engines?

These bearings are designed for specific Volvo engine codes, including B5252, B5254F/T, and B5234F/T, and are sized at +0.75mm. It is important to verify that your engine code and crankshaft journal size match the specifications for this bearing set before installation.
