What does the 0.040in O/S sizing mean for my engine rebuild?

This means the bearings are 0.040 inches larger in diameter than standard. This size is used when your engine's crankshaft journals and/or main housing bores have been machined to an oversize to correct wear or damage. It allows you to achieve the correct bearing clearance after machining.

What is the benefit of the coated overlay on these bearings?

The advanced overlay coating helps to reduce friction and wear, especially during the critical engine break-in period and under high-stress operating conditions. It provides an extra layer of protection against scuffing and helps maintain oil film integrity.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit into rebuilt Duramax diesel engines, it is always recommended to refer to the King Engine Bearings installation guidelines or your engine builder's specifications for proper installation procedures and torque values.
