Procedure

    1. SUBTASK 72-60-43-320-065 Machine the Roller Bearing Shoulder

    2. Refer to Figure.

      1. Machine the roller bearing shoulder.

      2. The preplating dimension must be 1.3691 in. minimum (34.775 mm minimum) in relation to surface D.

      3. Remove all damage and wear.

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

      5. Surface rough must be 63 microin. (1.6 micron) before plating.

    1. SUBTASK 72-60-43-240-061 Examine the Bevel Gearshaft

      1. Do the magnetic particle inspection for cracks.

      2. Refer to the SPM TASK 70-24-01-240-501.

      3. No cracks are permitted.

    1. SUBTASK 72-60-43-380-057 Shot-Peen the Roller Bearing Shoulder

      1. Shot-peen the roller bearing mating face to an intensity of 0.006A to 0.008A in.

      2. Refer to the SPM TASK 70-38-04-300-503.

    1. SUBTASK 72-60-43-330-058 Chromium Plate the Roller Bearing Shoulder

      1. Do the chromium plate.

      2. Refer to the SPM TASK 70-33-02-330-501.

      3. Plate to a sufficient thickness to permit the machining to the last dimensions.

      4. The plate out of the roller bearing mating face is permitted but must be removed.

    1. SUBTASK 72-60-43-370-061 De-embrittle the Gearshaft

      1. Put the gearshaft into the oven at 260 to 289 deg F (127 to 143 deg C) for 5 hours.

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

    1. SUBTASK 72-60-43-220-087 Examine the Plating

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

      2. Plating must have a constant color.

      3. No bubbles or sign of burned metal are permitted.

    1. SUBTASK 72-60-43-320-066 Machine the Roller Bearing Shoulder

    2. Refer to Figure.

      1. Machine the roller bearing shoulder.

      2. The last dimension must be between 1.3858 to 1.3701 in. (35.800 to 34.800 mm) in relation to surface D.

    1. SUBTASK 72-60-43-220-088 Examine the Chromium Plated Area

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

      2. The natural network of crack, made more apparent by grinding, is permitted.

      1. Measure the thickness of the plating.

      2. Do not accept thickness less than 0.001 in. (0.025 mm) after the last machining.

    1. SUBTASK 72-60-43-350-060 Record the Repair

      1. Vibro engrave VRS5628 adjacent to the part number.

      2. Remove the metal lifted by marking.

      3. Refer to the SPM TASK 70-09-00-400-501.
