What does the +0.75mm sizing mean for these main bearings?

The +0.75mm sizing indicates that these bearings are 0.75mm undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.75mm to remove wear or imperfections.

Why are main bearings important during an engine rebuild?

Main bearings support the crankshaft within the engine block. They create the necessary oil clearance to lubricate the rotating assembly and reduce friction. Using the correct, properly sized bearings is essential for engine health and performance.

Does this main bearing set come with installation instructions?

This set includes the main bearings themselves. It is recommended to refer to the manufacturer's installation instructions or a service manual for proper installation procedures, including required oil clearances and lubrication.
