Zusammenfassung:	A method for repairing an air cycle machine compressor housing includes removing a journal bearing support sleeve in an air cycle machine compressor housing, positioning a cylindrical insert within the air cycle machine compressor housing, wherein the cylindrical insert has an outer diameter greater than an outer diameter of at least one portion of the removed journal bearing support sleeve, an inner diameter less than an inner diameter of at least one portion of the removed journal bearing support sleeve, and a length greater than a length of the removed journal bearing support sleeve, welding the cylindrical insert to the air cycle machine compressor housing, and machining the welded cylindrical insert to form a replacement journal bearing support sleeve.
