      2. Mask the areas of the support 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 the machining to the last dimensions.

      3. The plating out of the angle gearbox casing mating surface 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.

    5. SUBTASK 72-60-32-370-051 De-embrittle the Support

      1. Put the support into an 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.

    6. SUBTASK 72-60-32-220-071 Examine the Support

      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.

    7. SUBTASK 72-60-32-320-054 Machine the Casing Mating Surface of the Support

    1. Refer to Figure.

      2. Machine the angle gearbox casing mating surface.

      1. The last dimension of the casing mating surface must be between 10.3778 in. and 10.3758 in. (263.596 mm and 263.545 mm) in relation to surface C.

      2. Chamfer where necessary.

    8. SUBTASK 72-60-32-220-072 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 the thickness of the plating.

      1. Do not accept thickness less than 0.0006 in. (0.015 mm) after the last machining.

    9. SUBTASK 72-60-32-350-060 Install the New Inserts

    1. Refer to Figure.

      2. Install the two new inserts.
