General
Refer to the TASKs which follow for the other related procedures:
TASK 72-00-32-020-001-B00 (REMOVAL-001, CONFIG-002) - Remove the Hydraulic Tubes, the Thermal Anti-Ice (TAI) Duct, the Pneumatic Starter Duct and the EEC Cooling Ducts from the LP Compressor/Intermediate Case Module.
TASK 72-00-32-020-002-B00 (REMOVAL-002, CONFIG-002) - Remove the LP Compressor/Intermediate Case Electrical Harnesses.
TASK 72-00-32-020-003-B00 (REMOVAL-003, CONFIG-002) - 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 EIPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the EIPC.
For all the parts identified in a different ATA Chapter/Section/Subject, the applicable ATA Chapter/Section/Subject comes before the Fig/item number.
Apply the approved CoMat 10-058 PENETRATING OIL before the removal of threaded parts. Let the parts soak before removal.
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.
