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.

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.

The No. 1 strut, which is the top position strut of the fan frame assembly, is identified by the five pressure tubes on the No. 1 strut leading edge.

This TASK gives the procedure to install the fan frame assembly. The subsequent TASKS give the procedure to assemble the LP compressor/intermediate case module.

Procedure

    1. SUBTASK 72-32-00-430-085 Install the Brackets A and B to the Fan Frame Assembly

    1. Refer to Figure.

    2. Attach a hoist to the shackle of the bracket B (part of IAE 1J12317 Turnover adapter 1 off).

    3. Lift and move the bracket B adjacent to the No. 8 and No. 9 struts of the fan frame assembly.

    4. NOTE

      Do not tighten the bolts at this step.

      Align the 10 bolt holes in the bracket B with the 10 threaded holes in the No. 8 and No. 9 struts. Safety the bracket B with the 10 bolts and washers.

    5. NOTE

      Do not tighten the nuts at this step.

      Align the four bolt holes in the bracket B with the four bolt holes in the flanges of the No. 8 and No. 9 struts. Safety the bracket B with the four screws, four nuts and the eight washers.

    6. Tighten equally the 10 bolts and the four nuts until the bracket B is installed in position.

    7. Remove the hoist from the shackle of the bracket B.

      8. Install the bracket A (part of IAE 1J12317 Turnover adapter 1 off) to the fan frame assembly.

      1. Do Step through Step with the bracket A to install the bracket A to the No. 3 and No. 4 struts of the fan frame assembly.

    2. SUBTASK 72-32-00-430-086 Install the lifting Slings to the Fan Frame Assembly

    1. Refer to Figure.

    2. Put a lifting sling around the roots of No. 3 and No. 4 struts and attach the lifting sling eyes on to the hook on a hoist. Keep the lifting sling loose.

    3. Put a second lifting sling around the roots of No. 8 and No. 9 struts and attach the lifting sling eyes on to the hook on the hoist. Keep the lifting sling loose.

    4. Adjust the hoist to make the lifting slings tighter. Make sure that the lifting slings are correctly installed.

    3. SUBTASK 72-32-00-430-087 Install the Fan Frame Assembly to the Turnover Stand

    1. Refer to Figure and Figure.

    2. Slowly lift the fan frame assembly and make sure that it is in a level position.

    3. Move the fan frame assembly adjacent to the supports A and B (part of IAE 1J12311 Turnover stand 1 off).

    4. Slowly lower the fan frame assembly until each square rod end of the brackets A and B is correctly engaged with each slot in the supports A and B.

    5. Install each of the two plates (part of the turnover stand) on to the supports A and B and safety with the four bolts and washers (part of the turnover stand).

    6. NOTE

      Make sure that the hole in the support C and one of the eight holes in the handle are aligned. If necessary, turn the handle to make the two holes aligned.

      Install the lock pin in to position to lock the handle of the turnover stand.

    4. SUBTASK 72-32-00-430-088 Remove the Two Lifting Slings from the Fan Frame Assembly

    1. Refer to Figure.

    2. WARNING

      DO NOT REMOVE THE LIFTING SLINGS UNTIL AFTER THE INSTALLATION OF THE LOCK PIN IN TO THE HANDLE OF THE TURNOVER STAND. THIS CAN PREVENT THE ROTATION OF THE FAN FRAME ASSEMBLY AND INJURY TO PERSONS.

      Adjust the hoist to loosen the lifting slings.

    3. Release the eyes of each lifting sling from the hook on the hoist and remove the lifting slings from the struts.

    5. SUBTASK 72-32-00-430-089 Turn the Fan Frame Assembly Horizontal with the No. 6 Strut Up

    1. Refer to Figure.

    2. Release the lock pin from the holes in the handle and the support C of the turnover stand.

    3. Turn the handle to set the fan frame assembly horizontal with the No.6 strut up.

    4. NOTE

      Make sure that the hole in the support C and one of the eight holes in the handle are aligned. If necessary, turn the handle to make the two holes aligned.

      Install the lock pin in to position to lock the handle.
