General

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.

Apply the approved penetrating oil before the removal if threaded parts. Let the parts soak before removal. For the approved oils and procedures, refer to SPM TASK 70-64-00-640-501.

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.

The No.1 strut, which is the top position strut of the fan frame assembly, is identified by the five pressure tubes on the No.1 strut leading edge.

This TASK gives the procedure to remove the LP compressor stage 2.5 vanes and the rear fairing.
