Procedure

    1. SUBTASK 72-41-12-210-001 Examine the HP Compressor Vortex Reducer Ring

    1. Refer to Figure and Figure.

      NOTE

      The number(s) of the lug(s) which has been dressed previously were recorded upon successful completion of VRS6086 to make it easier to identify the repair locations.

      NOTE

      The repaired location(s) on the individual lug(s) and the depth of the dressing were not recorded. Care must be taken during inspection to identify previously repaired locations as a second repair of the same lug is not permitted.

      2. Examine the HP Compressor Vortex Reducer Ring for previous applications of VRS6086.

        NOTE

        A combination of repairs at corresponding locations on Surface 1 and Surface 2 is not permitted.

        1. If the component has had VRS6086 applied previously and the lug with the defect(s) was repaired during the previous application.

        1. Reject.

        2. If the component has been repaired in accordance with VRS6086 previously and the previous repair location cannot be determined.

        1. Bedding check the proposed repair area to determine if the lug has been repaired before.

            1. If the bedding check of the repair area shows less than 90% bedding.

            1. Reject.

          3. If the bedding check shows greater than 90% bedding.

          1. Continue with the repair.

        3. If the component has not been repaired in accordance with VRS6086 previously.

        1. Continue with the repair.

      3. Examine the defect(s) on the HP Compressor Vortex Reducer Ring.

          1. If the repair will exceed the maximum permitted depth.

          1. Reject.

          2. If the repair area will remove material over more than 25% of the contact surface of the lug(s).

          1. Reject.

            NOTE

            A combination of repairs at corresponding locations on Surface 1 and Surface 2 is not permitted.

          3. If the lug(s) has not been repaired previously and the repair area will not remove more than 25% of the contact face of the lug.

          1. Mark the location(s) that are to be repaired and continue with the repair.

      4. Examine the identity marking location for a x mark adjacent to one of the lugs from a previous repair.

        NOTE

        The x mark will only exist if VRS6086 has been applied previously.

        1. If there is no x mark on the identity marking surface adjacent to one of the lugs.

        1. Continue the repair from Step.

        2. If there is an x mark on the identity marking surface adjacent to one of the lugs.

        1. Continue the repair from Step, Step or Step, as specified in TASK 72-41-12-200-001.

    2. SUBTASK 72-41-12-350-001 Identify a Reference Lug (If Required)

    1. Refer to Figure and Figure.

      2. If this is the first application of VRS6086 vibro-peen a circle with an X in it, x, at the identity marking location adjacent to the HP Compressor Vortex Reducer Ring Lugs to act as a reference.

        NOTE

        To determine the number of the Lug being repaired, use the lug with the vibro-peened x mark as the number 1 lug and count counter-clockwise, viewed from the front, to the repaired Lug.

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

  3. CAUTION

    DRESSING IN ACCORDANCE WITH PART 1 OF VRS6086 MUST ONLY BE DONE WHEN THE INSTRUCTION TO DO SO IS GIVEN IN THE INSPECTION/CHECK, REFER TO TASK 72-41-12-200-001.
