What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are designed for use when the crankshaft journals have been machined undersize by 1.0mm. This is a common practice during engine rebuilds to ensure proper oil clearance when the crankshaft has been reconditioned.

What is the construction of these main bearings?

These main bearings are made with a bimetal construction, featuring an aluminum base. This type of construction is chosen for its ability to handle load and heat while maintaining good bearing properties.

Are these bearings a direct replacement for all Mazda 626 models?

This specific bearing set is for the Mazda 626 with the F8 engine and is sized at +1.0mm. Always verify your engine code and the required bearing size before ordering to ensure correct fitment for your rebuild.
