Common Information

TASK 72-00-40-050-002 HP System Module Components - Remove The Active Clearance Control (ACC) Actuator, Removal-012

General

This TASK gives the procedure to remove the active clearance control (ACC) actuator.

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 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, Pubref 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.
