Procedure

    1. SUBTASK 72-60-28-320-061 Machine the Outer Diameter

    1. Refer to Figure.

      2. Machine the outer diameter.

      1. Remove all damage and wear.

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

      3. The preplating diameter must be between 3.2190 in. to 3.2162 in. (81.764 mm to 81.691 mm.).

    2. SUBTASK 72-60-28-230-055 Examine the Housing

      1. Do the fluorescent penetrant inspection for cracks.

      2. No cracks are permitted.

    3. SUBTASK 72-60-28-330-059 Nickel Plate the Outer Diameter

    1. Refer to Figure.

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

      3. Do the nickel plating.

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

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

      3. The plating out of the outer diameter area is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the housing.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    4. SUBTASK 72-60-28-370-057 De-embrittle the Housing

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

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

    5. SUBTASK 72-60-28-220-090 Examine the Plating

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

      1. Plating must have a constant color.

      2. No circumferential cracks are permitted.

      3. No rough and blistering are permitted.

    6. SUBTASK 72-60-28-320-062 Machine the Outer Diameter

    1. Refer to Figure.

      2. Machine the outer diameter.

      1. The last dimension of the outer diameter must be between 3.2269 in. to 3.2230 in. (81.964 mm to 81.864 mm).

      2. Clean up the edges of groove and chamfers, where necessary.

    7. SUBTASK 72-60-28-220-091 Examine the Nickel Plated Area

      1. Do the visual inspection of the plated areas for cracks and adhesion.

      1. Use a 4x magnifying glass.

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

      2. 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 72-60-28-350-065 Record the Repair

      1. Vibro engrave VRS5239 adjacent to the part number.

      1. Remove the metal lifted by marking.
