Procedure

    1. SUBTASK 72-50-53-320-061 Machine the Cover Seat Diameter of the Turbine Exhaust Case Assembly

    1. Refer to: Figure

      2. Machine the cover mating diameter.

      1. The mating diameter must be between 7.1987 to 7.2074in. (182.848 to 183.068 mm) after the removal of the damage.

        Remove all damage and wear.

        Keep the removal of material to the minimum necessary to remove the damage.

    2. SUBTASK 72-50-53-230-059 Examine the Turbine Exhaust Case Assembly

      1. Do the fluorescent penetrant inspection for cracks.

      1. Refer to the SPM TASK 70-23-02-230-501.

        No cracks are permitted.

      2. Drain the fluorescent penetrant from the struts.

      1. Repair, VRS3655 TASK 72-50-53-300-076 (REPAIR-076).

    3. SUBTASK 72-50-53-330-055 Nickel Plate the Cover Mating Diameter of the Turbine Exhaust Case Assembly

    1. Refer to: Figure

      2. Mask the areas of the turbine exhaust case not to be plated.

      3. Do the nickel plating.

      1. Refer to the SPM TASK 70-33-10-200-502.

        Plate to a sufficient thickness to permit the machining to the last dimensions.

        The plating out of the cover mating diameter is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the turbine exhaust case assembly.

      1. Flush with cold water.

        Flush with hot water.

        Dry with air blast.

    4. SUBTASK 72-50-53-370-056 De-embrittle the Turbine Exhaust Case Assembly

      1. Put the turbine exhaust case into a furnace at 266 to 302 deg F (130 to 150 deg C) for 12 hours.

      1. Do this process as soon as possible in less than 4 hours after the plating.

    5. SUBTASK 72-50-53-220-091 Examine the Turbine Exhaust Case Assembly

      1. Do the visual inspection of the plating for finish, cracks and adhesion.

      1. Plating must have a constant color.

        No circumferential cracks are permitted.

        No rough and blistering are permitted.

    6. SUBTASK 72-50-53-320-062 Machine the Cover Mating Diameter of the Turbine Exhaust Case Assembly

    1. Refer to: Figure

      2. Machine the cover mating diameter.

      1. The mating diameter must be between 7.1936 to 7.1976in. (182.718 to 182.818 mm).

        Chamfer where necessary.

    7. SUBTASK 72-50-53-220-092 Examine the Nickel Plated Area

    1. Refer to: Figure

      2. Do the visual inspection of the plated area for cracks and adhesion.

      1. Use a 4x magnifying glass.

        The natural network crack, emphasized by grinding, is permitted.

      3. Measure the thickness of the plating.

      1. Do not accept thickness less than 0.0006in. (0.015 mm) after the last machining.

    8. SUBTASK 72-50-53-350-059 Record the Repair

      1. Vibro engrave VRS5406 adjacent to the part number.

      1. Remove the metal lifted by marking the number.
