Procedure

    1. SUBTASK 72-50-23-326-051 Remove the Worn Machine Key

      NOTE

      When you have to repair the honeycomb also (Refer to VRS4080 TASK 72-50-23-300-006) you can braze the machine key in to position at the same time. Use the same filler and information which are given in the VRS4080 TASK 72-50-23-300-006.

      1. Machine off the worn machine key.

      1. It is permitted to electrical discharge machine the part, refer to the SPM TASK 70-32-03-320-501 and Figure. Do not remove parent material.

        Remove all signs of original braze filler before you weld in the new machine key.

    2. SUBTASK 72-50-23-110-055 Clean the Stage 7 Shroud Seal Segment

      1. Vapor degrease.

      1. Refer to the SPM TASK 70-11-01-300-503.

    3. SUBTASK 72-50-23-230-063 Examine the Stage 7 Shroud Seal Segment for Cracks

      1. Do the test for cracks.

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

        No cracks are permitted.

    4. SUBTASK 72-50-23-220-078 Examine the Stage 7 Shroud Seal Segment

      1. Dimensionally examine the machined areas.

      1. For dimensions refer to Figure. Use radius gage set, depth gage micrometer, dial caliper and vernier caliper.

    5. SUBTASK 72-50-23-310-055 Weld in the New Machine Key

      1. Tungsten inert gas weld the machine key in position.

      1. Clamp the machine key to prevent movement. Use the IAE IAE 3M14229 Clamping fixture 1 off. Use CoMat 03-197 WELDING FILLER WIRE to weld the locating key.

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

    6. SUBTASK 72-50-23-220-079 Do the Post Repair Inspection

      1. Examine the machined area for completed weld.

      1. Refer to the SPM TASK 70-31-13-310-501. Too much weld material is not permitted. Use illuminated comparator magnifier.

      2. Dimensionally examine the new machine key.

      1. For finish dimensions refer to Figure. Use dial caliper and vernier caliper.

    7. SUBTASK 72-50-23-230-064 Examine the Stage 7 Shroud Seal Segment for Cracks

      1. Do the test for cracks.

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

        No cracks are permitted.
