TASK 72-00-32-020-003-A00 (REMOVAL-003, CONFIG-001) Remove the LP compressor/intermediate case tubes and the electrical harness raceways
TASK 72-00-32-020-004 (REMOVAL-004) Remove the LP compressor/intermediate case components
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 the parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.
Apply the approved penetrating oil before the removal of threaded parts and parts with an interference fit. Let the parts soak before removal. For the approved oils and procedures, refer to the SPM TASK 70-64-00-640-501.
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.
Refer to Figure for details of the module flanges given in this procedure.
