Procedure

    1. SUBTASK 72-50-53-320-105 Machine the Oil Transfer Tube Mating Diameter

    1. Refer to: Figure

      2. Machine the oil transfer tube mating diameter before nickel plate.

      1. Keep material removal to a minimum so the plating will be 0.002 to 0.012 in. (0.05 to 0.30 mm) thick after finish machining.

        If the diameter was plated before, you can strip the plating.

        Refer to the SPM TASK 70-33-05-300-503.

    2. SUBTASK 72-50-53-230-093 Examine the Turbine Exhaust Case

      1. Fluorescent penetrant inspect the surface to be plated.

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

        No cracks are permitted.

    3. SUBTASK 72-50-53-330-069 Nickel Plate the Oil Transfer Tube Mating Diameter

    1. Refer to: Figure

      2. Apply a mask to the areas not be plated.

      3. Nickel plate the diameter.

      1. Refer to the SPM TASK 70-33-06-330-501.

        Apply the plating to a sufficient thickness to permit finish machining.

        NOTE

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

    4. Remove the mask.

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

      1. Clean and dry the case.

      1. Flush the case with cold water, then flush with hot water.

        Dry with air blast.

    5. SUBTASK 72-50-53-370-076 Bake the Turbine Exhaust Case after Nickel Plate

      1. Bake after nickel plate.

      1. Bake at 360 to 390 deg F (182 to 199 deg C) for three hours.

        Do this process as soon as possible in less than one hour after plating.

    6. SUBTASK 72-50-53-320-106 Machine the Oil Transfer Tube Mating Diameter after Nicekl Plate

    1. Refer to: Figure

      2. Finish machine the diamter after nickel plate.

      1. Machine the diameter to 0.378 to 0.382 in. (9.602 to 9.702 mm).

    7. SUBTASK 72-50-53-220-204 Examine the Repair

      1. Visually examine the plated area for cracks and plating that is not attached to the base metal.

      1. Use a 4X or greater magnifying glass.
