Procedure

    1. SUBTASK 72-60-28-320-075 Machine the Large Piloting Diameter of the Housing

    1. Refer to Figure.

      2. Machine the large piloting diameter.

      1. The diameter must be between 7.0815 to 7.0787 in. (179.870 to 179.800 mm).

        Remove all damage and wear.

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

    2. SUBTASK 72-60-28-230-059 Examine the Housing

      1. Do the fluorescent penetrant inspection for cracks.

      1. Refer to the SPM TASK 70-23-01-230-501.

        No cracks are permitted.

    3. SUBTASK 72-60-28-330-066 Nickel Plate the Large Piloting Diameter of the Housing

    1. Refer to Figure.

      2. Mask the areas of the housing not to be plated.

      3. Do the nickel plating.

      1. Refer to the SPM TASK 70-33-08-300-503.

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

        The plating out of the large piloting diameter is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the housing.

      1. Flush with cold water.

        Flush with hot water.

        Dry with air blast.

    4. SUBTASK 72-60-28-370-067 De-embrittle the Housing

      1. Put the housing into an oven at 241 to 260 deg F (116 to 127 deg C) for 60 to 90 minutes.

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

    5. SUBTASK 72-60-28-220-104 Examine the Housing

      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 72-60-28-320-076 Machine the Large Piloting Diameter of the Housing

    1. Refer to Figure.

      2. Machine the large piloting diameter.

      1. The diameter must be between 7.0866 to 7.0827 in. (180.000 to 179.900 mm).

        Clean up the edges of groove and chamfer where necessary.

    7. SUBTASK 72-60-28-220-105 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 0.0006 in. (0.015 mm) after the last machining.

    8. SUBTASK 72-60-28-350-072 Record the Repair

      1. Vibro engrave VRS5068 adjacent to the part number.

      1. Remove the metal lifted by marking the number.
