Common Information

TASK 72-41-20-440-007-A02 HPC Rear Cases And Vanes Assembly - Disassemble (For Subsequent Final Assembly) After Machining (Mechanical Clamping Tool Method), Assembly-007

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.

Make sure that the clamping tools are removed and the HP compressor rear cases and vanes are machined before you remove the stator vanes, rotor path ring or case. Refer to TASK 72-41-20-440-006-A02 (ASSEMBLY-006).

Refer to Figure for a sectional view of the HP compressor rear cases and vanes.

As each set of stator vanes are removed from the assembly they must be kept in IAE 1R18283 Cabinet 1 off. Make sure the stator vanes are put in to the cabinet in the correct sequence.

As each rotor path ring or case is removed they must be put into IAE 1R18281 Storage rack 1 off.

NOTE

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