Procedure

    1. SUBTASK 72-42-11-320-052 Machine the Front Outside Diameter Before Coating

    1. Refer to: Figure

      2. Machine diameter DH to the dimension given in the figure.

      1. Remove only the minimum quantity of material to get the dimension given in the figure.

        If the part was repaired on this diameter before, make sure you remove all the plasma spray coat.

    2. SUBTASK 72-42-11-350-057 Mask all the Areas that are not to be Plasma Spray Coated

    1. Refer to Figure.

      2. Mask all the areas that are not to be plasma spray coated.

      1. Do the procedure given in the SPMTASK 70-34-03-340-501.

        No coating is permitted on the face of the flange.

    3. SUBTASK 72-42-11-380-051 Grit Blast the Front Outside Diameter

    1. Refer to Figure.

      2. Grit blast the front inside seal diameter.

      1. Do the procedure given in the SPM TASK 70-34-03-340-501.

    4. SUBTASK 72-42-11-340-051 Apply Plasma Spray Coating to the Front Outside Diameter

    1. Refer to Figure.

      2. Apply plasma spray coating to the front outside diameter.

      1. Do the procedure given in the SPM TASK 70-34-03-340-501.

        Apply a sufficient thickness of coating to get the final machining dimensions given in the figure.

    5. SUBTASK 72-42-11-350-058 Remove the Mask and the Overspray Coating

    1. Refer to: Figure

    2. Remove the mask.

      3. Remove the overspray coating that is too much.

      1. Use a scraper that is not metal.

    6. SUBTASK 72-42-11-320-053 Machine the Front Outside Diameter

    1. Refer to: Figure

      2. Machine the plasma spray coating to the dimensions given in the figure.

      1. All dimensions apply when surfaces DF and DE are flat in 0.005in. (0.127 mm) and diameters DH and DF maintain a clearance envelope of 25.210in. (640.334mm) and 28.226in. (716.94 mm) in a free or held condition. Held contact is permitted only on surfaces DJ, DX, DE, DY and diameters DH and DF.

        In a free condition, surfaces DJ and DE are flat in 0.010in. (0.254 mm) and diameters DH and DF are between 25.174 and 25.239in. (639.42 and 641.07 mm) and 28.197 and 28.263in. (716.20 and 717.88 mm).

    7. SUBTASK 72-42-11-220-067 Examine the Front Outside Diameter

    1. Refer to: Figure

    2. Examine the front outside diameter to the dimensions given in the figure.

    8. SUBTASK 72-42-11-350-054 Mark the Part

    1. Refer to: Figure

      2. Mark the repair number VRS3033 on the diffuser case adjacent to the part number.

      1. Mark the part by the procedures given in the SPM TASK 70-09-00-400-501.

        Use the vibration peen method.

        NOTE

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