Procedure

    1. SUBTASK 72-50-21-325-005 Machine the Diameter "Z"

      NOTE

      If the LP turbine case was plasma spray repaired before, remove the old coating fully.

      1. Machine the diameter "Z".

      1. Use IAE 3M14318 Turning fixture 1 off and vertical turning lathe.

        Refer to Figure, Figure, Figure, Figure, and Figure.

        Keep the material removal to the minimum to allow subsequent repairs. Remove the old coating and damage fully.

    2. SUBTASK 72-50-21-220-167 Examine the Machined Surfaces

      1. Examine the machined surfaces dimensionally.

      1. For dimensions refer to Figure, Figure, Figure, Figure, and Figure.

        Use radius gage set and dial caliper and micrometer.

    3. SUBTASK 72-50-21-230-108 Examine the Machined Surfaces for Cracks

      1. Do the test for cracks.

      1. Refer to the SPM TASK 70-23-05-230-501.

        Use medium sensitivity level.

        No cracks are permitted.

    4. SUBTASK 72-50-21-110-105 Clean the LP Turbine Case

      1. Aqueous degrease.

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

    5. SUBTASK 72-50-21-340-063 Prepare the Surfaces for the Plasma Spray Procedure

      1. Mask the areas A3.

      1. Make sure that all adjacent surfaces have full protection. Use CoMat 02-047 TAPE, HEAT REFLECTIVE or CoMat 02-050 HIGH TEMPERATURE GLASS CLOTH TAPE.

        Refer to Figure, Figure, Figure, Figure, and Figure.

      2. Grit blast the area A1.

      1. The surface texture must be 120 to 200 microinch RMS (3.0 to 5.0 micrometer Ra). Blasting in area A2 is permitted.

      3. Replace the masking if necessary.

      1. Replace the damaged masking. Do not touch or bring unwanted material on the blasted areas.

    6. SUBTASK 72-50-21-340-064 Plasma Spray the Prepared Surfaces

      1. Plasma spray the area A1.

      1. Overspray in area A2 is permitted if it was blasted before, refer to Figure, Figure, Figure, Figure, and Figure. Make sure that there is sufficient material to do last machining. Refer to the SPM TASK 70-34-03-340-501. Use CoMat 03-080 METAL SPRAYING POWDER,Co BASE ALLOY.

    7. SUBTASK 72-50-21-340-065 Remove the Protection from the Masked Areas

      1. Remove the masking.

      1. Remove all the tape.

    8. SUBTASK 72-50-21-325-006 Machine the Coated Areas

      1. Machine the coated areas.

      1. Use IAE 3M14318 Turning fixture 1 off and vertical turning lathe.

        For dimensions refer to Figure, Figure, Figure and the SPM TASK 70-34-03-340-501.

    9. SUBTASK 72-50-21-110-106 Clean the LP Turbine Case

      1. Aqueous degrease.

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

    10. SUBTASK 72-50-21-220-168 Do the Post Repair Inspection

      1. Examine the repaired areas dimensionally.

      1. For actual dimensions refer to Figure, Figure, and Figure.

        Use dial caliper, micrometer, roughness microtester and radius gage set.

      2. Examine the coating.

      1. Refer to the SPM TASK 70-34-03-340-501 and SPM TASK 70-34-03-340-501-002 for acceptance standards.

        Use illuminated magnifier.

    11. SUBTASK 72-50-21-380-055 Make a Mark to Identify the Repair

      1. Vibropeen VRS4471 and applicable bee-hive symbol adjacent to the part number.

      1. Refer to the SPM TASK 70-09-00-400-501.

        Suffix for Stage 3 to 7 areas as follows:

        Stage 3 rear hook diameter VRS4471A.

        Stage 4 rear hook diameter VRS4471B.

        Stage 5 rear hook diameter VRS4471C.

        Stage 6 rear hook diameter VRS4471D.

        Stage 7 rear hook diameter VRS4471E.
