Procedure

    1. SUBTASK 72-00-32-210-051 Remove the LPC Bleed Valve Actuating Master and Slave Actuators and the Brackets

    1. Make sure that the actuators and the brackets are removed from the fan frame. If they are installed, remove them. Refer to TASK 72-00-40-020-002-A00.

    2. SUBTASK 72-00-32-210-052 Install the Setting Fixture

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

      2. NOTE

        Do not install the magnetic stand, the digital dial gage and the torque wrench in this SUBTASK.

        Install the brackets A and B (parts of IAE 1J12444 Setting fixture 1 off) onto the fan frame assembly.

      1. Align the four aligning holes in each brackets with the aligning pins on the fan frame.

      2. Attach the brackets to the fan frame. Safety each bracket with the four socket head cap screws (part of the setting fixture). Tighten the socket head cap screws.

      3. Connect the rod assemblies to the brackets.

      1. Align the holes in the crank with the hole E in each bracket.

      2. Align the hole in each rod assembly with the holes in the crank and the bracket.

      3. Make full installation of set pins.

    3. SUBTASK 72-00-32-210-053-A00 Examine the Rigging Position (Pre SBE 72-0031)

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

    2. Install wrenches into wrench holes in the cranks.

    3. Make half installation of the set pins.

    4. Slowly turn the left and right cranks with the wrenches to push the rod assemblies forward until the bleed valves are at open position. Slowly turn the left and right cranks with the wrenches to pull the rod assemblies rearward until the bleed valves are at closed position. Do this procedure three or four times and make sure that the rod assemblies and the actuating mechanism move lightly.

    5. Make full installation of the set pins into the holes E.

    6. Remove the wrenches.

      7. Install a digital dial gage and magnetic stand assemblies onto each bracket and rod assembly.

      1. Install the magnetic stand onto the bracket.

      2. Adjust position of the assembly so that clock pin of the digital dial gage touches the rear end of the rod end adapter.

    8. Adjust the digital dial gages to zero.

    9. Install torque wrenches into wrench holes in the cranks.

    10. Make half installation of set pins.

      11. Measure the movement of the rod assemblies.

        1. Torque the cranks to 173 to 193 lbfin (19.54 to 21.79 Nm).

        1. Direction of the torque must be so that the rod assemblies are pulled rearward.

        2. NOTE

          The rod assemblies are pulled by 130 to 143 lbs (59 to 65 Kg) by the torque.

          You must torque the left and right cranks at the same time.

      2. Keep the torque in Step and read indication of the digital dial gages.

      3. Write the indication of the left digital dial gage as ML on an applicable record sheet. Write the indication of the right digital dial gage as MR. Use minus sign for forward movement of the rod assemblies.

      4. Loosen the torque.

      5. Do Step thru Step eight times.

      12. Make sure that the values ML and MR are within the following limits:

      1. Each of the 16 values ML and MR is not more than 0.102 in. (2.60 mm).

    13. NOTE

      Refer to Step for the rejected engine.

      If the values ML and MR are within the limits, accept the engine. If the values ML and MR are not in the limits, reject the engine.

    14. Make full installation of set pins.

    15. Read indications of the digital dial gages.

    16. Make sure that the indications are between minus 0.0019 and 0.0019 in. (minus 0.048 and 0.048 mm).

    17. If the indications are not in the limits, make half installation of the set pins and go to Step.
