Zusammenfassung:	A repaired turbine housing for use in an air cycle machine including a journal bearing bore having an inlet, an outlet, and an inner diameter of about 2.580±0.001 inches (6.553±0.003 centimeters). The repaired turbine housing including a cylindrical insert secured within the journal bearing bore. The cylindrical insert having a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The diametric interference being between about 0.000-0.003 inches (0.000-0.008 centimeters). The cylindrical insert being inserted into the inlet of the journal bearing bore up to the step. The step has an outer diameter greater than the outer diameter of the cylindrical insert. The inner surface of the cylindrical insert includes at least one selected inner diameter.
