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 the Fig/item number.

Remove and discard the lockwire before the component is disconnected.

Apply the approved CoMat 10-058 PENETRATING OIL before the removal of threaded parts. Let the parts soak before removal.

During the removal procedure make sure that the harnesses are held temporarily along their different lengths. This is to prevent too much strain on the harnesses, cables and electrical connectors.

During the removal procedure put the special plastic caps on the electrical connectors and receptacles. This is to give protection from unwanted fluids or materials.

During the removal procedure remove the lacing tape which attaches the different harnesses to each other.

Seal all openings when the tubes or components are disconnected to prevent contamination from unwanted material.

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).

NOTE

To identify the consumable materials refer to the PCI.
