General

This TASK gives the procedure to replace (by hand cropping) individual HP compressor stator vanes for stage 6 on an assembled front case.

As each stator vane is removed its location in the assembly must be recorded.

There is no requirement to measure stator to rotor drum clearance when performing this repair procedure.

The practices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the SPM.

Procedure

    1. SUBTASK 72-41-30-350-001 Remove the Damaged Vane

    1. Position the rear case to get access to the damaged vane.

      2. Remove the damaged vane.

    3. NOTE

      Position in the assembly of the vane removed to gain access to the damaged vane must be recorded.

    2. SUBTASK 72-41-30-350-002 Remove, Clean and Measure the Nearest Serviceable Vane

    1. Refer to Figure and Figure.

      2. Remove the nearest serviceable vane.

      1. Locate the damaged vane.

        Remove the nearest adjacent serviceable vane.

      3. Clean the nearest serviceable vane.

      1. Refer to SPM TASK 70-11-34-300-503.

      4. Measure the nearest serviceable vane.

      1. Use workshop inspection equipment.

        Measure the vane at three positions given in figure.

        Record the measurements.

    3. SUBTASK 72-41-30-220-509 Measure the Replacement New Vane

    1. Refer to Figure and Figure.

      2. Measure the replacement new vane.

      1. Use workshop inspection equipment.

        Measure the vane at three positions given in figure.

        Record the measurements.

    4. SUBTASK 72-41-30-220-510 Mark-out the Replacement New Vane

    1. Refer to Figure and Figure.

      2. Mark the replacement new vane.

      1. Mark the area to be cropped from the tip on the replacement new vane.

        Use workshop inspection equipment.

        Measure the vane at three positions given in figure.

        Use the difference in dimensions recorded in Step para D. and Step.

        Make sure the mark is within 0.002 in. (0.05 mm) of the required distance from the vane platform.

    5. SUBTASK 72-41-30-350-003 Crop the Replacement New Vane

      CAUTION

      IF YOU USE MECHANICAL CUTTERS ON THE VANE, MAKE LIGHT CUT TO PREVENT OVERHEATING OF THE MATERIAL.

    1. Refer to Figure and Figure.

      2. Attach the replacement vane.

      1. Attach the replacement new vane into an applicable fixture with soft jaws.

        The fixture must safety the vane at the airfoil not only at the root.

      3. Remove tip material by cropping.

      1. Hand crop the tip of the vane.

        Make sure that the tip is dressed in the direction from the leading edge tip to the trailing edge tip.

        If necessary, use mechanical hand cutters, smooth hand metal file and/or CoMat 05-140 ABRASIVE STONE SILICON CARBIDE silicon abrasive stone.

        Make sure that you get the dimensional limits set in Step.

      4. Blend and polish the replacement new vane tip.

      1. Blend and polish the replacement new vane tip.

        Make sure that the tip is dressed in the direction from the leading edge tip to the trailing edge tip.

        Use CoMat 05-020 WATERPROOF SILICON CARBIDE waterproof silicon carbide paper, CoMat 05-082 WATERPROOF SILICON CARBIDE waterproof silicon carbide paper and CoMat 05-127 ABRASIVE PAD scotch brite.

        Make sure that you get the dimensional limits set in Step.

    6. SUBTASK 72-41-30-110-055 Swab Etch the Cropped Area

      1. Do a local swab etch of the cropped area.

      1. Refer to SPM TASK 70-11-39-300-503, SUBTASK 70-11-39-300-001.

    7. SUBTASK 72-41-30-230-001 Crack Test the Cropped Area

      1. Locally crack test the cropped area.

      1. Refer to SPM TASK 70-23-01-230-501.

        Cracks are not permitted.

        If you find cracks, do the SUBTASK 72-41-30-220-059 thru Step again with a new replacement vane.

    8. SUBTASK 72-41-30-110-056 Clean the Replacement New Vane

      1. Clean the replacement new vane.

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

    9. SUBTASK 72-41-30-220-511 Dimensionally Examine the Replacement New Vane

    1. Refer to Figure and Figure.

      2. Dimensionally examine the replacement new vane.

      1. Use workshop inspection equipment.

        Measure the vane length at three positions given in figure.

        Make sure the vane length is within 0.002 in. (0.05 mm) of the adjacent serviceable vane length measured in Step para D.

        If the vane is outside the required limits do the Step thru Step again with a new replacement vane.

        .

    10. SUBTASK 72-41-30-350-004 Identify the Replacement New Vane

      1. Mark the repair symbol adjacent to the part number.

      1. Refer to SPM TASK 70-09-00-400-501, SUBTASK 70-09-00-400-001.

        Use vibro-engraving equipment.

        Mark the symbol 20 inside a triangle adjacent to the part number.

    11. SUBTASK 72-41-30-350-005 Install the Replacement New Vane

      1. Install the replacement new vane in original vane set.

    2. NOTE

      Vanes must be installed again at their original positions in the assembly.
