Procedure

    1. SUBTASK 72-50-53-320-101 Prepare the Cover Bore Diameter for Nickel Plating

    1. Refer to Figure.

      2. Prepare the cover bore diameter for nickel plate to the limits in Figure by one or more of the methods that follow.

      1. Machine the diameter of the cover bore. Keep material removal to a minimum so the plating will be 0.002 in. to 0.012 in. (0.05 mm to 0.30 mm) thick after finish machining.

        2. Remove nickel plate by SPM TASK 70-33-06-300-503. Mask other non-nickel strip region. See Figure.

        1. Part is steel with a hardness is greater than 25 HRC and less than 40 HRC.

    2. SUBTASK 72-50-53-110-212 Clean the Turbine Exhaust Case (TEC)

      1. Clean the part.

      1. Refer to SPM TASK 70-11-03-300-503.

    3. SUBTASK 72-50-53-230-091 Examine the Surfaces to be Plated

      1. Do a local fluorescent penetrant inspection of the repair area.

      1. Refer to SPM TASK 70-23-05-230-501 (High Sensitivity). No indications permitted.

    4. SUBTASK 72-50-53-380-064 Apply a Mask to the Turbine Exhaust Case

      1. Apply a mask to the areas of the Turbine Exhaust Case that are not to be plated.

    5. SUBTASK 72-50-53-330-066 Nickel Plate the Diameter of the Cover Bore

    1. Refer to Figure.

      2. Nickel plate the diameter by one of the following processes.

        1. Refer to SPM TASK 70-33-06-300-503 (Nickel Plating on Stainless Steel, Cobalt, and Nickel Base Alloys).

        1. Part is stainless steel with a hardness greater than 25 HRC and less than 40 HRC.

        2. Part cannot be damaged if heated to 375 deg F (190 deg C) or greater.

        3. Apply the plating to a sufficient thickness to permit finish machining. Plating outside the repair area is permitted but must be removed.

        2. Refer to SPM TASK 70-33-28-300-503 (Brush Nickel Plating).

        1. Part is 400 series stainless steel with a hardness greater than 25 HRC and less than 40 HRC.

        2. Part cannot be damaged if heated to 375 deg F (190 deg C) or greater.

        3. Apply the plating to a sufficient thickness to permit finish machining. Plating outside the repair area is permitted but must be removed.

    6. SUBTASK 72-50-53-320-102 Machine the Diameter of the Cover Bore after Nickel Plate

    1. Refer to Figure.

      2. Machine the diameter of the cover bore after nickel plate.

      1. Machine the diameter to 6.943 in. to 6.947 in. (176.353 mm to 176.453 mm). Final plating thickness 0.002 in. to 0.012 in. (0.05 mm to 0.30 mm).

    7. SUBTASK 72-50-53-110-213 Clean the Turbine Exhaust Case (TEC)

      1. Clean the part.

      1. Refer to SPM TASK 70-11-03-300-503.

    8. SUBTASK 72-50-53-220-202 Examine the Repair

      1. Do a visual and dimensional inspection of the repair location. Refer to Figure.

      1. Use a 4X or greater magnifying glass to examine for cracks and adhesion.

    9. SUBTASK 72-50-53-350-224 Identify the Repair

    1. Mark VRS3111 on the repaired Turbine Exhaust Case adjacent to the part number.

      2. Make a permanent mark by the procedure given in the SPM TASK 70-09-00-400-501.

      1. Use vibration peen marking method.

      2. Remove high metal caused by marking the number.

      3. If the VRS repair number is already marked on the part, do not mark the repair number again.
