Procedure

    1. SUBTASK 72-60-41-320-061 Machine the Bearing Support Seat Diameter of the Angle Gearbox Casing

    1. Refer to Figure and Figure.

      2. Machine the bearing seat diameter.

      1. The diameter must be between 6.30118 in. to 6.30709 in. (160.050 mm to 160.200 mm) after the removal of the damage.

      2. Remove all the damage and wear. Keep the removal of the material to the minimum necessary to remove the damage.

    2. SUBTASK 72-60-41-220-089 Examine the Angle Gearbox Casing

      1. Do the local fluorescent penetrant inspection for cracks.

      1. Refer to SPM TASK 70-23-05-230-501.

      2. No cracks are permitted.

    3. SUBTASK 72-60-41-330-063 Nickel Plate the Bearing Seat Diameter of the Angle Gearbox Casing

    1. Refer to Figure and Figure.

      2. Mask the areas of the casing 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.

      3. The plating out of the bearing seat diameter is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the support.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    4. SUBTASK 72-60-41-370-004 De-embrittle the Angle Gearbox Casing

      1. Put the casing into the oven at 241 deg F to 260 deg F (116 deg C to 127 deg C) for 60 to 90 minutes.

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

    5. SUBTASK 72-60-41-220-090 Examine the Angle Gearbox Casing

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

      1. Plating must have a constant colour.

      2. No circumferential cracks are permitted.

      3. No roughness and blisters are permitted.

    6. SUBTASK 72-60-41-320-062 Machine the Bearing Seat Diameter of the Angle Gearbox Casing

    1. Refer to Figure and Figure.

      2. Machine the bore diameter.

      1. The dimension of the diameter must be between 6.29921 in. to 6.30079 in. (160.000 mm to 160.040 mm). Clean the edge and chamfer where necessary.

    7. SUBTASK 72-60-41-220-091 Examine the Nickel Plated Area

    1. Refer to Figure and Figure.

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

      1. Use a Magnifying glass, 4x. The natural network of crack, emphasized by grinding, is permitted.

    8. SUBTASK 72-60-41-350-072 Record the Repair

      1. Make a mark VRS5109 adjacent to the part number.

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