Procedure

    1. SUBTASK 75-24-48-350-065 Remove the Bracket

      1. Remove the bracket.

    2. SUBTASK 75-24-48-350-066 Remove all the Soil from the Surface

      1. Remove all the oxides, hydrocarbon, grit and scale from the surface to be welded and adjacent area by local cleaning.

      1. Refer to Cleaning-000 TASK 75-24-48-100-100.

    3. SUBTASK 75-24-48-220-059 Examine the Turbine CLG Manifold Assembly

      1. Visually examine the turbine CLG manifold assembly.

      2. Refer to SPM TASK 70-21-01-220-501.

      2. Penetrant examine the turbine CLG manifold assembly.

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

      3. Replace the joint, if required.

      1. Refer to VRS1536 (Repair-006) TASK 75-24-48-300-006.

      4. Weld the damaged surface, if required.

      1. Refer to VRS1532 (Repair-001) TASK 75-24-48-300-001.

    4. SUBTASK 75-24-48-350-067 Weld the Bracket

    1. Refer to Figure.

      2. Set the bracket and turbine CLG manifold assembly to the fixture.

    3. Finish the surface of turbine CLG manifold assembly to fit the bracket.

    4. Tack weld the bracket.

      5. Weld the bracket to the manifold and two junction corners of the bracket by tungsten inert gas (TIG) weld.

      1. Refer to Figure.

      2. Refer to SPM TASK 70-31-02-300-501.

    6. NOTE

      If it is necessary, remove the turbine cooling manifold assembly from the fixture before you weld the two junction corners of the bracket.

      Remove the turbine CLG manifold assembly from the fixture.

    5. SUBTASK 75-24-48-220-060 Examine the Joint of Turbine CLG Manifold Assembly

      1. Replace the joint, if required.

      1. Refer to VRS1536 (Repair-006) TASK 75-24-48-300-006.
