Procedure

    1. SUBTASK 72-50-53-320-090 Machine the Locating Pin Hole in the Front Flange of the Turbine Exhaust Case

    1. Refer to Figure and Fig. .72-50-053-990-064-002.

      2. Machine the locating pin hole in the front flange.

      1. Maintain the 0.270 in. (6.86 mm) maximum dimension. Keep the removal of material to the minimum necessary to remove the damage and to permit sufficient plating thickness.

        NOTE

        Do not machine the elongated locating pin hole more than 0.270 in. (6.86 mm) circumferentially.

    2. SUBTASK 72-50-53-230-084 Examine the Turbine Exhaust Case

      1. Fluorescent penetrant inspect the turbine exhaust case.

      1. Refer to the SPM TASK 70-23-05-230-501.

        No cracks are permitted.

    3. SUBTASK 72-50-53-380-054 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.

    4. SUBTASK 72-50-53-330-064 Nickel Plate the Locating Pin Hole in the Front Flange of the Turbine Exhaust Case

    1. Refer to Figure and Figure.

      2. Nickel plate the locating pin hole in the front flange.

      1. Refer to the SPM TASK 70-33-06-300-503.

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

        Plating outside the locating pin hole is permitted but must be removed.

    3. Remove the mask.

    5. SUBTASK 72-50-53-110-104 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.

    6. SUBTASK 72-50-53-370-072 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 four hours.

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

    7. SUBTASK 72-50-53-220-182 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.

    8. SUBTASK 72-50-53-320-091 Machine the Locating Pin Hole in the Front Flange of the Turbine Exhaust Case after Nickel Plate

      1. Machine the locating pin hole in the front flange after nickel plate.

      1. Refer to Figure.

    9. SUBTASK 72-50-53-220-183 Examine the Repair

    1. Refer to Figure and Figure.

      2. Examine the turbine exhaust case after nickel plate.

      1. Refer to 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).

    10. SUBTASK 72-50-53-350-094 Identify the Repair

      1. Mark VRS3116 on the repaired turbine exhaust case adjacent to the part number.

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

        Use vibrating marking pencil.

        Remove high metal caused by marking the number.
