    Engine Crankshaft Crank Grinding 010010 Myth

    Mar 27, 2017 The thickness of the steel backing varies instead of the bearing material, so the risk of a bearing failure is no greater with a .040 under bearing than it is with a .010 under bearing. We can repair a down journal today with the crank welders that were invented in the 50s, so most cores are reusable even if they have a bad journal or ...

    Oversize Vs Undersize Engine Bearings It Still Runs

    An oversized bearing has the same inside diameter but a bit more material on the outside diameter. An undersized bearing measures the same outside but is thicker on the inside. For instance, if a completed bearing measures 3 inches on the outside diameter and has a stock metal thickness of 0.20-inch, then its inside diameter will measure 2.40-inch.
