      2. Mask the areas of the seal housing not to be sprayed.

      3. Abrasive blast the air seal land.

      1. Refer to the SPM TASK 70-12-02-120-501.

        Use abrasive blasting facility.

        Pressure of the air: 42.67 psi (294.2 Kpa).

        Distance of the spraying: 6 to 7.87 in. (150 to 200 mm).

    4. Remove the mask.

      5. Clean the seal housing.

      1. Clean with dry air blast.

    6. SUBTASK 72-50-53-370-067 Metal Plasma Spray the Air Seal Land

      CAUTION

      METAL PLASMA SPRAY THE BOND COAT ON THE LAND DIAMETER AS SOON AS POSSIBLE IN LESS THAN TWO HOURS AFTER THE ABRASIVE BLASTING. DO THE ABRASIVE BLASTING AGAIN IF YOU EXCEED THIS TIME LIMIT.

      CAUTION

      METAL PLASMA SPRAY THE TOP COAT ON THE LAND DIAMETER AS SOON AS POSSIBLE IN LESS THAN TEN MINUTES AFTER THE BOND COAT SPRAY.

    1. Refer to: Figure

      2. Mask the areas of the seal housing not to be sprayed.

      3. Preheat the surface to be sprayed.

      1. Preheat temperature: 194 to 248 deg F (90 to 120 deg C).

      4. Metal plasma spray the bond coat on the air seal land.

      7. Clean the seal housing.

      1. Clean with dry air blast.

    7. SUBTASK 72-50-53-220-137 Examine the Plasma Sprayed Surface

      1. Do the visual inspection of the coating for good adhesion.

      1. Use a 4X magnifying glass.

        No cracks or separation from the parent material are permitted.

        Do the process again if there are cracks.

    8. SUBTASK 72-50-53-350-068 Install the Oil Seal Housing

      1. Install the oil seal housing on the turbine exhaust case.
