    1. Refer to Figure and Figure.

    2. Disassemble and remove the bolts, the clips, the nuts and the washers which attach the electrical connectors together at the bracket. Remove and discard the lockwire at the bracket, refer to the view at A.

    3. Disconnect the electrical connectors 4022KS-A, 4022KS-B, 4022KS-C and temporarily tie them clear of the actuator with CoMat 06-086 TIES.

    2. SUBTASK 72-00-40-050-059-B00 Disconnect the EEC Harness Electrical Connectors from the VSV Actuator (SBE 71-0111)

    1. Refer to Figure and Figure.

    2. Remove and discard the lockwire from the connectors 4022KS-A, 4022KS-D, 4022KS-B and 4022KS-C. Remove and discard the lockwire at the bracket, refer to the view at A.

    3. Disconnect the electrical connectors 4022KS-A, 4022KS-B, 4022KS-C and 4022 KS-D and temporarily tie them clear of the actuator with CoMat 06-086 TIES.

    3. SUBTASK 72-00-40-050-060 Remove the VSV Actuator

      NOTE

      Some fuel leakage could occur during this procedure. It is recommended that an applicable container be available.

    1. Refer to Figure, Figure, Figure and Figure.

    2. Disconnect the two fuel servo tubes (44 and 46) from the VSV actuator and remove the two packings.

    3. Disconnect the fuel drain tube (47) from the VSV actuator.

    4. Remove the bolts, washers and clipnuts from the clip positions 5745 and 5746.

      5. Remove the VSV actuator.

      1. Move the VSV actuating mechanism to the high speed position.

      2. Install IAE 1R18254 Rigging pin 1 off through the bearing housing and locate in the crankshaft recess.

      3. Remove the nut HPC Variable Stator Vane Actuator (75-32-42, 01-082), the washer HPC Variable Stator Vane Actuator (75-32-42, 01-083) and the bolt HPC Variable Stator Vane Actuator (75-32-42, 01-084) to disconnect the control rod.

      4. Hold the VSV actuator, remove the four bolts and the two washers that attach the actuator to the HP compressor case and remove the actuator. Remove the bracket HPC Variable Stator Vane Actuator (75-32-41, 01-070).

      5. NOTE
