Common Information

TASK 72-32-00-030-008-B00 LPC/Intermediate Case Module - Remove The LPC Bleed Duct, Booster Stage Bleed Valve And Actuating Mechanism, LPC Stage 2.5 Vane, And The Right And Left Rod Assemblies, Disassembly-008

General

This TASK gives the procedure to remove the LP compressor bleed duct, the booster stage bleed valve and actuating mechanism, the LP compressor stage 2.5 vane and the right and left rod assemblies.

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

Discard all tab washers removed in this procedure.

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.
