Location of Remanufacture Information Tag

"TG" will be stamped on the top surface of a remanufactured cylinder block that has been machined by Caterpillar to a dimension between 321.50 to 321.75 mm (12.657 to 12.667). A Caterpillar remanufactured cylinder block that is machined to this dimension will have "TG" on the remanufacture information tag. These remanufactured cylinder blocks require a thick cylinder head gasket.
