Abstract
Processing used pistons includes receiving defective and non-defective pistons removed from service, sorting the used pistons into standard and expanded processing categories, and repairing a defect in pistons in the expanded processing category via welding. An inventory of interchangeable replacement pistons is populated with remanufactured pistons from both the standard and expanded processing categories.
