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

The +0.75mm sizing 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 clean up worn or damaged surfaces and achieve proper oil clearance.

What is trimetal construction?

Trimetal construction refers to a bearing design that uses three layers of materials. This typically includes a steel backing for strength, a copper-lead alloy for strength and embeddability, and a softer overlay like babbitt for conformability and reduced friction against the crankshaft.

Do these bearings come with installation instructions?

While these bearings are designed as a direct fit, it is always recommended to refer to the manufacturer's installation instructions or a professional service manual for the correct procedures and specifications, especially regarding oil clearance and assembly torque.

About this part

Product Details

If you're rebuilding the bottom end of your Mercedes OM611 engine, especially in a Freightliner Sprinter 2500 from 2002-2006, a solid set of main bearings is crucial. These King Engine Bearings are built with a strengthened trimetal construction, which means they're designed to handle the loads and stresses of daily driving and heavier work. They're a direct replacement for your original bearings, ensuring they fit right into your engine block.

The trimetal design offers a good balance of strength and wear resistance, important for keeping your crankshaft supported properly. This particular set is sized at +0.75mm, meaning it's intended for use when the crankshaft journals have been machined down by that amount to clean up wear or damage. Using the correct undersize bearing is key to achieving proper oil clearance and ensuring the longevity of your engine rebuild.
