Procedure

    1. SUBTASK 79-21-41-320-064 Machine the Piloting Diameter of the Drive Gear

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. Remove all damage and wear.

      2. The piloting diameter must be between 0.8657 and 0.8726 in. (21.990 and 22.165 mm) after the removal of the damage.

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

    2. SUBTASK 79-21-41-230-059 Examine the Drive Gear

      1. Do the magnetic particle inspection for cracks.

      1. Refer to SPM TASK 70-24-01-240-501.

      2. No cracks are permitted.

    3. SUBTASK 79-21-41-330-063 Nickel Plate the Piloting Diameter of the Drive Gear

    1. Refer to Figure.

      2. Mask the areas of the drive gear 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 machining to the last dimensions indicated in the reference figure.

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

    4. Remove the mask.

      5. Clean and dry the drive gear.

      1. Flush with cold water

      2. Flush with hot water

      3. Dry with air blast

    4. SUBTASK 79-21-41-370-055 De-embrittle the Drive Gear

      1. Put the drive gear 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 79-21-41-220-161 Examine the Drive Gear

      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 or blistering are permitted.

    6. SUBTASK 79-21-41-320-065 Machine the Piloting Diameter of the Drive Gear

    1. Refer to Figure.

      2. Machine the piloting diameter.

      1. Machine the piloting diameter, the dimension must be between 0.8647 to 0.8653 in. (21.980 to 21.965 mm).

      2. Chamfer, where necessary.

    7. SUBTASK 79-21-41-220-162 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 a thickness of less than 0.0006 in. (0.015 mm), after the last machining.

    8. SUBTASK 79-21-41-350-065 Record the Repair

    1. Refer to Figure.

      2. Vibro engrave VRS5298 adjacent to the part number.

      2. Remove the metal lifted by marking.
