Procedure

    1. SUBTASK 72-60-42-320-066 Machine the Piloting Diameter of the Radial Gearshaft Support

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. The piloting diameter must be between 5.1153 in. to 5.1102 in. (129.930 mm to 129.800 mm).

      2. Remove all damage and wear.

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

    2. SUBTASK 72-60-42-230-056 Examine the Support

      1. Do the fluorescent penetrant inspection for cracks.

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

      2. No cracks are permitted.

    3. SUBTASK 72-60-42-330-059 Nickel Plate the Piloting Diameter of the Radial Gearshaft Support

    1. Refer to Figure.

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

      3. Do the nickel plating.

      1. Refer to the 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 piloting diameter is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the support.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    4. SUBTASK 72-60-42-370-063 De-embrittle the Support

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

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

    5. SUBTASK 72-60-42-220-090 Examine the Support

      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 72-60-42-320-067 Machine the Piloting Diameter of the Radial Gearshaft Support

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. The diameter must be between 5.1181 in. to 5.1165 in. (130.000 mm to 129.960 mm).

      2. Chamfer and clean up edges of groove, where necessary.

    7. SUBTASK 72-60-42-220-091 Examine the Nickel Plated Area

    1. Refer to Figure.

      2. Do the visual inspection of the plated area for cracks and adhesion.

      2. 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 72-60-42-350-064 Record the Repair

      1. Vibro engrave VRS5092 adjacent to the part number.

      1. Remove the metal lifted by marking the number.
