Procedure

    1. SUBTASK 72-60-22-320-055 Machine the Piloting Diameter of the Housing

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. Remove all damage and wear.

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

        The piloting diameter must be between 7.3986 to 7.3937 in. (187.924 to 187.800 mm).

    2. SUBTASK 72-60-22-230-053 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 72-60-22-110-053 Remove the Grease from the Housing

      1. Do the vapor degreasing.

    4. SUBTASK 72-60-22-330-053 Nickel Plate the 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 SPMTASK 70-33-08-330-503 .

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

      3. The plating out of the plating 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.

    5. SUBTASK 72-60-22-370-053 De-embrittle the Housing

      1. Put the housing into a furnace at 266 to 302 deg F (130 to 150 deg C) for 12 hours.

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

    6. SUBTASK 72-60-22-220-073 Examine the Housing

      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.

    7. SUBTASK 72-60-22-320-056 Machine the Piloting Diameter of the Housing

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. The piloting diameter must be between 7.4016 to 7.3998 in. (188.00 to 187.954 mm).

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

    8. SUBTASK 72-60-22-220-074 Examine the Nickel Plated Areas

      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.

    9. SUBTASK 72-60-22-350-053 Record the Repair

      1. Vibro engrave VRS5033 adjacent to the part number.

      1. Remove the metal lifted by marking.
