Procedure

    1. SUBTASK 79-11-41-320-082 Machine the Piloting Diameter of the Deaerator Assembly

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. Remove all damage and wear. The piloting diameter must be between 6.4976 and 6.4882 in. (165.040 and 164.800 mm) after the removal of the damage.

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

    2. SUBTASK 79-11-41-230-066 Examine the Deaerator Assembly

      1. Do the fluorescent penetrant inspection for cracks.

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

      2. No cracks are permitted.

    3. SUBTASK 79-11-41-330-064 Nickel Plate the Piloting Diameter of the Deaerator Assembly

    1. Refer to Figure.

      2. Mask the areas of the deaerator assembly not to be plated.

      3. Do the nickel plating.

      1. Refer to SPM TASK 70-33-08-300-503. Plate to a sufficient thickness to permit machining to the last dimensions indicated in the reference figure.

      2. The plating out of the piloting diameter area is permitted, but must be removed.

    4. Remove the mask.

      5. Clean and dry the deaerator assembly.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    4. SUBTASK 79-11-41-370-053 De-embrittle the Deaerator Assembly

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

      1. Do this procedure as soon as possible, in less than 4 hours, after plating.

    5. SUBTASK 79-11-41-220-118 Examine the Deaerator 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.

      2. No roughness or blistering is permitted.

    6. SUBTASK 79-11-41-320-055 Machine the Piloting Diameter of the Deaerator Assembly

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. Machine the piloting diameter, the dimension must be between 6.4980 to 6.4960 in. (165.050 and 165.000 mm).

      2. Chamfer, where necessary.

    7. SUBTASK 79-11-41-220-119 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.

      2. The natural network crack, shown by grinding is permitted.

      3. Measure the thickness of the plating.

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

    8. SUBTASK 79-11-41-350-060 Record the Repair

    1. Refer to Figure.

      2. Vibro-engrave VRS5215 adjacent to the part number.
