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 standard size bearings. This is typically used when the crankshaft journals have been machined to a larger size during an engine rebuild to correct wear or damage.

Are these bearings a direct replacement for all Cummins 2.8 Isf engines?

These bearings are designed for the Cummins 2.8 Isf engine. It is always recommended to verify fitment with your specific engine application and consult the manufacturer's specifications before installation.

What is the primary function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create the necessary clearance for the crankshaft to rotate smoothly while allowing oil to flow between the bearing and the crankshaft journal, preventing direct metal-to-metal contact.
