Procedure

    1. SUBTASK 72-50-53-350-088 Remove the Nut Plates from the Turbine Exhaust Case

      1. Remove the nut plates.

      1. Refer to TASK 72-50-53-300-069, Repair 069 VRS3256 (REPAIR-069).

    2. SUBTASK 72-50-53-320-082 Machine the Rear Face of the Rear Inner Flange of the Turbine Exhaust Case

      1. Machine the rear face of the rear inner flange.

      1. Refer to Figure.

        Maintain the 10.0177 in. (254.450 mm) minimum dimension. Keep the removal of material to the minimum necessary to remove the damage and to permit sufficient plating thickness.

    3. SUBTASK 72-50-53-230-082 Examine the Turbine Exhaust Case

      1. Fluorescent penetrant inspect the turbine exhaust case.

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

        No cracks are permitted.

    4. SUBTASK 72-50-53-380-051 Apply a Mask to the Turbine Exhaust Case

      1. Apply a mask to the areas of the turbine exhaust case that are not to be plated.

    5. SUBTASK 72-50-53-330-060 Nickel Plate the Rear Face of the Rear Inner Flange of the Turbine Exhaust Case

    1. Refer to Figure.

      2. Nickel plate the rear face of the rear inner flange.

      1. Apply nickel plate to a sufficient thickness to permit finish machining.

        Plating outside the repair area is permitted but must be removed.

    3. Remove the mask.

    6. SUBTASK 72-50-53-110-099 Clean the Turbine Exhaust Case

      1. Clean the turbine exhaust case.

      1. Flush the case with cold water.

        Flush the case with hot water.

        Dry the case with air blast.

    7. SUBTASK 72-50-53-370-068 Bake after Nickel Plate

      1. Bake the turbine exhaust case after nickel plate.

      1. Put the case into a furnace at 350 to 400 deg F (176 to 204 deg C) for three hours.

        Do this process as soon as possible in less than four hours after nickel plate.

    8. SUBTASK 72-50-53-220-176 Examine the Turbine Exhaust Case

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

      1. The plate must have a constant color.

        No circumferential cracks are permitted.

        No roughness or blisters are permitted.

    9. SUBTASK 72-50-53-320-083 Machine the Rear Face of the Rear Inner Flange of the Turbine Exhaust Case after Nickel Plate

      1. Machine the rear face of the rear inner flange after nickel plate.

      1. Refer to Figure.

    10. SUBTASK 72-50-53-220-177 Examine the Repair

      1. Examine the turbine exhaust case after nickel plate.

      1. Refer to Figureand TASK 72-50-53-200-000 (INSPECTION/CHECK-000).

        Use a 4X magnifying glass to examine for cracks.

        The normal network of cracks that are emphasized by grinding are permitted.

        The thickness of the plate after finish machining must be a minimum of 0.0006 in. (0.015 mm).

    11. SUBTASK 72-50-53-350-089 Install the Nut Plates on the Turbine Exhaust Case

      1. Install the nut plates on the turbine exhaust case.

      1. Refer to TASK 72-50-53-300-069, Repair 069 VRS3256 (REPAIR-069).

    12. SUBTASK 72-50-53-350-090 Identify the Repair

      1. Mark VRS3087 on the repaired turbine exhaust case adjacent to the part number.

      1. Make a permanent mark by the procedure given in SPM TASK 70-09-00-400-501.

        Use a vibrating marking pencil.

        Remove high metal caused by marking the number.
