Common Information
TASK 72-00-40-020-003-B00 HP System Module - Remove The Components, Ducts, Electrical Harnesses, And Tubes From The HPC Case Vertical Splitline, Removal-003
General
This TASK gives the procedure to remove the components, ducts, electrical harnesses and tubes from the HP compressor case vertical splitline. Refer to the TASKs which follow for other related procedures:
TASK 72-00-40-020-001-B00 - Remove the components, the electrical harnesses and the tubes from the HP turbine,
TASK 72-00-40-020-002-B00 - Remove and disconnect the components, the electrical harnesses and the tubes from the front of the HP compressor case,
TASK 72-00-40-020-004 - Remove the remaining HP system module components, tubes and the air off-take ducts.
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 Fig./item number.
Apply the approved CoMat 10-058 PENETRATING OIL before the removal of threaded parts. Let the parts soak before removal.
Remove and discard the lockwire before the tube or connector is disconnected.
When electrical connections are disconnected special plastic caps must be installed.
All the electrical harnesses removed in this procedure must have their maintenance completed as given in the Component Maintenance Manual (CMM-EHC-V2500-1IA).
All the tubes, hoses and ducts removed in this procedure must have their maintenance completed, as given in the Component Maintenance Manual (CMM-THD-V2500-1IA).
Seal all openings to prevent contamination from unwanted materials.
Discard all rubber seal rings removed in this procedure.
