      1. Refer to Repair, VRS5025, TASK 72-60-22-300-005 (REPAIR-005).

    2. SUBTASK 72-60-22-320-087 Machine the Mating Surface of the Housing

    1. Refer to Figure.

      2. Machine the mating surface.

      1. The preplating dimension must be between 1.0157 to 1.0185 in. (25.800 to 25.870 mm) in relation to surface B, after the removal of the damage. Remove all damage and wear. Keep the removal of the material to the minimum necessary, to remove the damage.

    3. SUBTASK 72-60-22-230-059 Examine the Housing

      1. Do the fluorescent penetrant inspection for cracks.

      1. Refer to the SPM TASK 70-23-01-230-501.

        No cracks are permitted.

    4. SUBTASK 72-60-22-330-072 Nickel Plate the Seal Housing Mating Surface

    1. Refer to Figure.

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

      3. Do the nickel plating.

      1. Refer to the SPM TASK 70-33-08-300-503.

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

        The plating out of the mating surface is permitted, but must be removed.

    4. Remove the mask.

      5. Clean and dry the housing.

      1. Flush with cold water.

      2. Flush with hot water.

    5. SUBTASK 72-60-22-370-067 De-embrittle the Housing

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

      1. Do this procedure as soon as possible, in less than 4 hours, after plating.

    6. SUBTASK 72-60-22-220-118 Examine the Housing

      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 or blistering are permitted.

    7. SUBTASK 72-60-22-320-088 Machine the Seal Housing Mating Surface

    1. Refer to Figure.

      2. Machine the mating surface.

      1. The dimension must be between 1.0197 to 1.0276 in. (25.900 to 26.100 mm).

      2. Chamfer, where necessary.

      3. Use grinding machine.

    8. SUBTASK 72-60-22-220-119 Examine the Nickel Plated Area

    1. Refer to Figure.

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

      1. Use a 4X magnifying glass.

      2. The natural network crack, emphasized by grinding is permitted.

      3. Measure the thickness of the plating.

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

    9. SUBTASK 72-60-22-350-090 Install the Threaded Inserts

    1. Refer to Figure.

      2. Install the inserts.

      1. Refer to Repair, VRS5025, TASK 72-60-25-300-005 (REPAIR-005).
