General

This TASK gives the procedure to remove the components and the air off-take ducts from the HP compressor/diffuser case assembly. Refer to the TASKs which follow for other related procedures:

TASK 72-00-40-020-001-A00 (REMOVAL-001, CONFIG-001) or TASK 72-00-40-020-001-B00 (REMOVAL-001, CONFIG-002). Remove the components, the electrical harnesses and the tubes from the HP turbine.

TASK 72-00-40-020-002-A00 (REMOVAL-002, CONFIG-001) or TASK 72-00-40-020-002-B00 (REMOVAL-002, CONFIG-002). Remove and disconnect the components, the electrical harnesses and the tubes from the front of the HP compressor case.

TASK 72-00-40-020-003-A00 (REMOVAL-003, CONFIG-001) or TASK 72-00-40-020-003-B00 (REMOVAL-003, CONFIG-002). Remove the components, the ducts, the electrical harnesses and the tubes from the HP compressor case vertical splitline.

Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For 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 CoMat 10-058 PENETRATING OIL before the removal of threaded parts. Let the parts soak before removal.

All ducts removed in this procedure must have their maintenance completed, as given in the Component Maintenance Manual (CMM-THD-V2500-1IA).

Discard all rubber seal rings removed in this procedure.

Seal all openings to prevent contamination from unwanted materials.

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.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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