What does the 0.75mm undersize mean for my engine?

The 0.75mm undersize 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 ensure proper oil clearance if the original journals are worn or damaged.

What is the construction of these main bearings?

These main bearings feature a bimetal construction. They have an aluminum base, which is a common and effective material for engine bearings, designed to work with the rotating crankshaft.

Are these bearings sold individually or as a set?

This product is a Main Bearing Set, meaning it includes all the necessary main bearings required for a complete engine rebuild for the specified applications.
