Procedure

    1. SUBTASK 72-60-25-320-073 Machine the Small Piloting Diameter of the Fuel Pump Drive Housing

    1. Refer to Figure.

      2. Machine the small piloting diameter.

      1. The preplating dimension must be between 5.0366 to 5.0311 in. (127.930 to 127.790 mm) after the removal of the damage.

      2. Remove all damage and wear.

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

    2. SUBTASK 72-60-25-230-054 Examine the Housing

      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 72-60-25-330-066 Nickel Plate the Small Piloting Diameter of the Fuel Pump Drive 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 SPM TASK 70-33-08-300-503.

      2. Plate to a sufficient thickness to permit the machining to the last dimensions indicated in the reference figure.

      3. The plating out of the close 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 72-60-25-370-061 De-embrittle the Housing

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

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

    5. SUBTASK 72-60-25-220-074 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.

    6. SUBTASK 72-60-25-320-074 Machine the Small Piloting Diameter of the Fuel Pump Drive Housing

    1. Refer to Figure.

      2. Machine the small piloting diameter.

      1. The dimension must be between 5.0390 to 5.0378 in. (127.990 to 127.960 mm).

      2. FIR in relation to surface A and diameter B.

      3. Clean up the edge of groove and chamfer where necessary.

    7. SUBTASK 72-60-25-220-075 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 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 72-60-25-350-075 Record the Repair

      1. Vibro engrave VRS 5057 adjacent to the part number.

      1. Remove the metal lifted by marking the number.
