Procedure

    1. SUBTASK 72-44-40-120-052 Clean the Stage 1 HPT Outer Seal Assembly

      1. Clean the outer seal assembly.

      1. Refer to TASK 72-44-40-100-001 (CLEANING-000).

    2. SUBTASK 72-44-40-320-052 Machine the Flange Tabs of the Stage 1 HPT Outer Seal Assembly to Remove Wear

      1. Machine the flange tabs of the outer seal assembly to remove wear.

      1. Refer to Figure for the flange thickness and width limit.

    3. SUBTASK 72-44-40-220-062 Inspect the Tab Surfaces of the Stage 1 HPT Outer Seal Assembly for Wear that Remains after Machining

      1. Inspect the tab surfaces for wear that remains after machining to the minimum thickness and/or width.

      1. Cracks or wear are not permitted.

    4. SUBTASK 72-44-40-120-053 Clean the Area of the Stage 1 HPT Outer Seal Assembly to be Repaired

      1. Clean the area to be weld repaired.

      1. Use an austenitic stainless wire brush.

    5. SUBTASK 72-44-40-310-051 Weld to Build Up the Tabs of the Stage 1 HPT Outer Seal Assembly

      1. Weld to build up the tabs to a sufficient thickness and width to permit finish machining.

        1. Use CoMat 03-284 WELDING FILLER WIRE, NiBASE and the GTAW-MA method.

        1. Refer to the SPM TASK 70-31-13-310-501 and Figure.

        2. Refer to Figure for the tab thickness and width after finish machining.

    6. SUBTASK 72-44-40-220-063 Inspect the Tabs of the Stage 1 HPT Outer Seal Assembly for Distortion

      1. Inspect the tabs for distortion.

      1. Use a surface plate and the limits as shown in Figure to check for distortion.

    7. SUBTASK 72-44-40-370-051 Stress Relieve the Stage 1 HPT Outer Seal Assembly

      1. Stress relieve the outer seal assembly.

      1. Refer to the SPM TASK 70-37-01-370-501, Cycle 12A.

    8. SUBTASK 72-44-40-320-053 Finish Machine the Stage 1 HPT Outer Seal Assembly
