General

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

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

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.

Refer to the SPM TASK 70-63-02-400-501 for the general instructions on the repair of surface protection.

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.

NOTE

Special tools are identified in the procedure by the tool primary number.

Procedure

    1. SUBTASK 72-00-50-560-059 Install Lifting Turn Adapter to the TEC Rear Flange

    1. Refer to Figure.

    2. Attach the hoist equipment to the lifting eye hook of the IAE 1F10108 Lifting turn adapter 1 off.

    3. CAUTION

      YOU MUST NOT LET THE LIFTING TURN ADAPTER HIT THE TEC REAR FLANGE OR OTHER PARTS OF THE ENGINE.

      Lift and position the lifting turn adapter above the TEC rear flange so the lifting eye hook will align with the TDC (12 o'clock position) when the engine is turned in the horizontal atitude.

    4. Install the lifting turn adapter on the TEC rear flange, tighten the 12 tool flange bolts and 12 tool lock nuts.

    2. SUBTASK 72-00-50-560-060 Install the Trunnions and Lift Sling to the LP Compressor/Intermediate Case Module

    1. Refer to Figure and Figure.

    2. Attach IAE 1J12008 Trunnion 2 off, to IAE 1J12000 Lift bracket 2 off. Secure with the eight trunnion bolts and the eight trunnion washers.

    3. Attach the trunnion/lift bracket assemblies on to the LP compressor and intermediate case module, between flange FE and FD. Secure with the four tool bolts and nuts.

      4. Attach IAE 1F10051 Two cable sling 1 off, to the trunnions on the module.

      1. Attach a hoist to the lift eye on the lift sling.

      2. Lift the sling.

      3. Lower the lift sling to permit the hook and bolt plate to be attached to the trunnions on the LP compressor/intermediate case module. Refer to Figure.

      4. Attach the hook and bolt plates to the outer trunnions. Insert the safety clip to safety the lift sling.

    3. SUBTASK 72-00-50-560-061 Lift and Turn the LP Compressor/Intermediate Case Assembly, HP System and LP Turbine Modules in to the Horizontal Position,

    1. Refer to Figure and Figure.

    2. Remove the eight tool nuts, the eight tool bolts and the eight tool washers which attach the LP compressor/intermediate case module front flange to the working stands, IAE 1J12210 Vertical build stand.

    3. Use the rear hoist to lift the modules from the working stands.

    4. Remove the four working stands from below the LP compressor/intermediate case module.

    5. Use the front hoist to turn the modules into the horizontal position.

      6. Install the LP compressor/intermediate case module, HP system and LP turbine modules on to the support posts and cradle pedestal/spacer support equipment.

      1. Make sure that the trunnion supports, (Part of IAE 1F10028 Support Pedestal 2 off) are in their upper position (upper hole of the pedestal).

      2. Make sure the support bracket (Part of IAE 1P16002 Cradle pedestal 1 off), is at its mid position.

      3. Adjust the height of the LP compressor/intermediate case module, HP system and LP turbine modules to permit the support posts and the cradle pedestal to be installed.

      4. Make sure there is sufficient clearance between the LP compressor/intermediate case, HP/LP system modules and the ground to permit the external gearbox module to be installed. With IAE 1F10024 Support spacer used in conjuction with IAE 1P16002 Cradle pedestal the floor to engine centerline height is 68.9 in. (176cm).

      5. Put the support posts adjacent to the trunnion assemblies with the trunnion supports below the trunnions.

      6. Put the cradle pedestal under the HP/LP system module assembly, with the support assembly slightly forward of the diffuser case rear flange. Make sure that the large face of the support assembly points forward.

      7. Turn the adjustment handle on the cradle pedestal until the support assembly touches the diffuser case.

      8. Lower the lift slings, to allow the support posts and cradle pedestal to take the weight of the modules. This will permit the lift sling, hook and bolt plates to be removed.

      9. Make sure the engine horizontal center line is level. If necessary, use the cradle pedestal to level the engine.

      10. Remove the hook and bolt plates from the front trunnions.

      11. Put the wide lift sling on to a suitable work surface.

    4. SUBTASK 72-00-50-560-062 Remove the Lifting Turn Adapter from the TEC Rear Flange

    1. Refer to Figure.

    2. Loosen the 12 lock nuts and flange bolts which secure the IAE 1F10108 Lifting turn adapter 1 to the TEC rear flange.

    3. CAUTION

      YOU MUST NOT LET THE LIFTING TURN ADAPTER HIT THE TEC REAR FLANGE OR OTHER PARTS OF THE ENGINE.

      Use the attached hoist equipment to remove the lifting turn adapter clear of the TEC rear flange.

    4. Put the lifting turn adapter on a suitable work surface and remove the hoist.
