What does the +.026mm sizing mean for my engine?

The +.026mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.026 millimeters. This is typically done to remove minor wear or imperfections from the crankshaft journals during an engine rebuild.

What is the benefit of the specialized overlay material?

The specialized overlay material on these bearings is formulated to provide good resistance to wear and fatigue. This is important for the demanding conditions within an engine's bottom end, helping to ensure the longevity of the bearings and the crankshaft.

Do these bearings come with installation instructions?

While these bearings are designed for a specific fit, it is always recommended to consult your vehicle's official service manual for detailed installation procedures, including proper torque specifications and oil clearance checks.

Product Details

If you're rebuilding the bottom end of your Holden Alloytec 175/190 engine, a fresh set of main bearings is crucial. These main bearings from King Engine Bearings are specifically sized at +.026mm, meaning they are designed to be used when the crankshaft journals have been machined down by 0.026 millimeters to clean up wear or damage. Proper main bearings keep the crankshaft properly supported and aligned within the engine block, ensuring smooth operation and preventing premature wear.

King Engine Bearings are known for their well-built construction. This set uses a specialized overlay material that offers good resistance to wear and fatigue, which is important for the high-stress environment inside an engine. The precise sizing ensures a proper fit on a machined crankshaft, helping to restore correct oil clearances. This is important because the oil film between the bearing and the crankshaft is what actually supports the rotating assembly.

When installing these bearings, make sure your crankshaft journals have been professionally machined and measured to the +.026mm undersize specification. Always refer to your vehicle's service manual for the correct installation procedures and torque specifications.
