Procedure

    1. SUBTASK 72-60-42-320-082 Machine the Pilot Diameter C of the Oil Duct

    1. Refer to Figure.

      2. Machine the pilot diameter.

      1. The preplating diameter must be between 1.9243 in. to 1.9350 in. (48.878 mm to 49.150 mm).

      2. Remove all damage and wear.

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

    2. SUBTASK 72-60-42-240-001 Examine the Oil Duct

      1. Do a penetrant inspection for cracks.

      1. Refer to TASK 72-60-42-200-007, SUBTASK 72-60-42-230-062.

      2. Cracks are not permitted.

    3. SUBTASK 72-60-42-380-001 Shotpeen the Pilot Diameter

      1. Shotpeen the bearing journal surface to an intensity of 6 to 8A.

    4. SUBTASK 72-60-42-110-001 Clean the Oil Duct

      WARNING

      WHEN YOU USE CoMat 01-001 SOLVENT, DELETED YOU MUST USE THE NECESSARY PROTECTIVE CLOTHING. DO NOT GET THE SOLVENT ON YOUR SKIN OR IN YOUR EYES. YOU MUST NOT SMOKE WHEN YOU USE THE SOLVENT AS THE VAPOR MAY CHANGE AND BECOME TOXIC.

      1. Do the vapor degreasing

      1. Refer to SPM TASK 70-11-01-300-503.

    5. SUBTASK 72-60-25-330-004 Chromium Plate the Pilot Diameter C

    1. Refer to Figure.

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

      3. Chromium plate the pilot diameter.

      1. Refer to SPM TASK 70-33-02-300-503.

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

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

    4. Remove the masking.

      5. Clean and dry the fuel oil duct.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    6. SUBTASK 72-60-42-370-001 Do the Embrittlement Relief to the Oil Duct

      1. Put the oil duct into a furnace at 284 deg F to 320 deg F (140 deg C to 160 deg C) for 5 hours.

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

    7. SUBTASK 72-60-42-220-001 Examine the Oil Duct

      1. Do the visual inspection of the plating for finish, cracks and adhesion.

      1. The plating must have a constant color. Blistering and signs of burned metal are not permitted.

    8. SUBTASK 72-60-42-320-001 Machine the Pilot Diameter C of the Oil Duct

    1. Refer to Figure.

      2. Machine the pilot diameter.

      1. The pilot diameter must be between 1.9360 in. to 1.9370 in. (49.175 mm to 49.200 mm).

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

    9. SUBTASK 72-60-42-220-002 Examine the Chromium Plated Areas

    1. Refer to Figure.

      2. Do the visual inspection of chromium plated areas 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 0.001 in. (0.025 mm) after the final machining.

    10. SUBTASK 72-60-42-350-001 Identify the Repair

    1. Refer to Figure.

      2. If required, vibro etch VRS5687 adjacent to the part number.

      1. Refer to the SPM TASK 70-09-00-400-501, SUBTASK 70-09-00-400-001.
