General

Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the IPC.

For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.

For standard torque data and procedures, refer to TASK 70-41-01-400-501 and TASK 70-41-02-400-501.

Special torque data and assembly tolerances are included in the procedure.

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS, unless other lubricants are referred to in the procedure.

To identify, lubricate and install seal rings, refer to TASK 70-44-01-400-501.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to TASK 70-38-21-380-501.

The number for each radial location must be identified in a clockwise direction. These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.

Transportation covers/blanks must be removed immediately before installation of the components.

      2. Safety the vertical stand with the four arms.

      Refer to Figure.

    3. Install the expanding retainer to the inner diameter of the LP turbine shaft. Attach the support fixture to the rear inner flange of the turbine exhaust case.

    4. Turn the hand wheel counterclockwise until the support is installed safely in the rear end of the LP turbine shaft.

    5. Turn the knob counterclockwise to push the clamps against the inner diameter of the LP turbine shaft.

    6. Attach the IAE 1F10052 Two cables sling 1 off to the rear spools of the IAE 1F10058 Handling fixture 1 off.

    7. Lift the handling fixture. Turn the front end down.

    8. Lower the handling fixture carefully. Engage the handling fixture on the sleeve. Align the handling fixture with the rear flange of the turbine exhaust case. Make sure that the guide pin of the handling fixture is aligned to the turbine exhaust case.

    9. Attach the handling fixture to the rear flange of the turbine exhaust case with the 13 bolts and washers. Tighten the bolts, refer to Figure.

    10. CAUTION

      MAKE SURE THAT THE NUTS ARE TIGHTENED. IF THE FIXTURES ARE NOT CORRECTLY SECURED THE LP TURBINE CASE AND ROTOR PARTS CAN BE DAMAGED DURING HANDLING OF THE LP TURBINE MODULE.

      Safety the expanding retainer to the handling fixture with the two nuts. Tighten the nuts.

    3. SUBTASK 72-00-50-560-054-B00 V2500-A5: Attach the Handling Fixture to the LP Turbine Module

    1. NOTE

      2. 1 off is installed to the IAE 1F10049 Vertical stand 1 off.

      3. Safety the vertical stand with the four arms.

      Refer to Figure.

    3. Install the expanding retainer to the inner diameter of the LP turbine shaft. Attach the support fixture to the rear inner flange of the turbine exhaust case.

    4. Turn the hand wheel counterclockwise until the support is installed safely in the rear end of the LP turbine shaft.

    5. Turn the knob counterclockwise to push the clamps against the inner diameter of the LP turbine shaft.

    6. Attach the IAE 1F10052 Two cables sling 1 off to the rear spools of the IAE 1F10058 Handling fixture 1 off.

    7. Lift the handling fixture. Turn the front end down.

    8. Lower the handling fixture carefully. Engage the handling fixture on the sleeve. Align the handling fixture with the rear flange of the turbine exhaust case. Make sure that the guide pin of the handling fixture is aligned to the turbine exhaust case.

    3. Turn down the locknut.

    4. Turn down the lockring.

    5. Remove the eight bolts, nuts and washers which attach the LP turbine module to the vertical stand.

    6. Attach the IAE 1F10052 Two cables sling 1 off to the front spools of the handling fixture. Make sure that the spools of the handling fixture are in the correct position at the center of gravity.

    7. Lift the LP turbine module until the front end of the LP turbine shaft is free of the locating fixture.

    8. Remove the LP turbine module from the vertical stand.

    6. SUBTASK 72-00-50-560-057-A00 V2500-A1: Turn the LP Turbine Module in to Horizontal Position

      NOTE

      If IAE 1M14127 Support plate 2 off are removed, install support plates to the LP turbine case front flange and the LP turbine shaft before LP turbine module is turned into the horizontal position.

    1. Turn the LP turbine module in to horizontal position.

    7. SUBTASK 72-00-50-560-057-B00 V2500-A5: Turn the LP Turbine Module into Horizontal Position
