Procedure

    1. SUBTASK 72-60-22-320-063 Machine the Inner Diameter of the Starter Seal Housing

    1. Refer to Figure.

      2. Machine the inner diameter of the starter seal housing.

      1. The inner diameter must be between 2.3166 in. to 2.3115 in. (58.843 mm to 58.713 mm).

      2. Remove all damage and wear.

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

    2. SUBTASK 72-60-22-230-054 Examine the Starter Seal Housing

      1. Do the fluorescent penetrant inspection for cracks.

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

      2. No cracks permitted.

    3. SUBTASK 72-60-22-110-057 Clean the Starter Seal Housing

      1. Do the vapor degreasing.

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

    4. SUBTASK 72-60-22-330-057 Nickel Plate the Inner Diameter of the Starter Seal Housing

    1. Refer to Figure.

      2. Mask the areas of the housing 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 starting seal housing areas is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the seal housing.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    5. SUBTASK 72-60-22-370-060 De-embrittle the Starter Seal Housing

      1. Put the housing into a furnace at 266 deg F to 302 deg F (130 deg C to 150 deg C) for 12 hours.

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

    6. SUBTASK 72-60-22-220-081 Examine the Inner Diameter

      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 72-60-22-320-064 Machine the Inner Diameter of the Starter Seal Housing

    1. Refer to Figure.

      2. Machine the inner diameter of the housing.

      1. The diameter must be between 2.3104 in. to 2.3088 in. (58.683 mm to 58.643 mm).

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

    8. SUBTASK 72-60-22-220-082 Examine the Inner Diameter of the Starter Seal Housing

    1. Refer to Figure.

      2. Do the visual inspection of the plated areas 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 thickness less than 0.0006 in. (0.015 mm) after the last machining.

    9. SUBTASK 72-60-22-350-057 Record the Repair

      1. Vibro engrave VRS5204 adjacent to the part number.

      1. Remove the metal lifted by marking.
