Procedure

    1. SUBTASK 72-60-25-320-069 Machine the Seal Housing Seat of the Fuel Pump Drive Housing

    1. Refer to Figure.

      2. Machine the seal housing seat.

      1. The diameter must be between 2.8331 in. to 2.8346 in. (71.960 mm to 72.000 mm) after the removal of the damage.

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

      3. Remove all damage and wear.

      4. Deleted.

      3. Blend sharp edges around the three drain holes.

      1. Refer to Figure.

    2. SUBTASK 72-60-25-220-072 Examine the Fuel Pump Drive Housing

      1. Inspect the housing for cracks in the area of the seat.

    3. SUBTASK 72-60-25-330-062 Apply the Chromate Conversion Coating

      1. Apply the chromate conversion coating to the machined surfaces.

      1. Refer to the SPM TASK 70-38-02-300-503.

    4. SUBTASK 72-60-25-350-071 Install the Bushing

    1. WARNING

      DO NOT TOUCH THE HOT PARTS WITHOUT PROTECTIVE GLOVES.
      HOT PARTS CAN CAUSE REDDENING AND BLISTERING OF THE SKIN, IF THE HANDS ARE NOT PROTECTED.
      IMMERSE THE CONTACTED AREA IN COLD WATER, FOR 10 MINUTES, IF THE SKIN IS BURNED. IMMEDIATELY GET MEDICAL ATTENTION IF PAIN OR BLISTERING PERSISTS.

      CAUTION

      INSTALL BUSHING IN MACHINED BORE IMMEDIATELY AFTER REMOVAL FROM FREEZER; OTHERWISE BUSHING CANNOT BE CORRECTLY INSTALLED.

      Refer to Figure.

    2. CAUTION

      MAKE SURE THAT THE LEAD IN CHAMFER OF THE BUSHING POINTS AWAY FROM THE DRIFT.

      Install the bushing on the IAE 3F10336 Drift, bushing (dia 67) 1 off.

    3. Increase the temperature of the housing and/or decrease the temperature of the assembled drift and bushing.

    4. Use an Oven and/or a Freezer.

      NOTE

      The difference in temperature between the parts must be 216 deg F (120 deg C).

    5. Do not increase the temperature of the housing above 284 deg F (140 deg C).

    6. Do not decrease the temperature of the assembled drift and bushing below -58 deg F (-50 deg C).

    7. Remove the housing from the oven and/or the assembled drift and bushing from the freezer.

    8. Install the bushing into machined seat.

    9. Use IAE 3F10336 Drift, bushing (dia 67) 1 off and an arbor press.

    10. Give sufficient back-up support, at bushing bore area, to prevent housing distortion when you install the bushing.

    11. Allow the parts to reach ambient temperature.

    12. Remove the drift.

    5. SUBTASK 72-60-25-320-070 Machine the Inner Diameter of the Bushing

    1. Refer to Figure.

      2. Machine the inner diameter of the bushing.

      1. The dimensions must be between 2.6791 in. to 2.6831 in. (68.050 mm to 68.150 mm).

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

      3. Chamfer where necessary.

      4. Deleted.

    6. SUBTASK 72-60-25-330-063 Apply the Chromate Conversion Coating

      1. Apply the chromate conversion coating to the machined surfaces of the bushing.

      1. Refer to the SPM TASK 70-38-02-300-503.

    7. SUBTASK 72-60-25-350-072 Record the Repair

      1. Vibro engrave VRS 5053 adjacent to the part number.

      1. Remove the metal lifted by marking.
