Thats what it says in my copy of the servicing notes for crankshaft journal diameters for 910 series engines. If you're talking line boring the block, you need to take account of the thickness of the bearing shells to get the diameter required. The max undersize for reground journals is stated as 0.0200 in. if you intend to grind the shaft.
