Common Information
TASK 72-32-00-430-008-A00 LPC/Intermediate Case Module - Install The LPC Bleed Duct, Booster Stage Bleed Valve And Actuating Mechanism, And Right And Left Rod Assemblies, Assembly-008 - Pre SBE 72-0233
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.
For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.
For standard torque data and procedures, refer to the SPM TASK 70-41-00-400-501, SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.
Special torque data is identified with the symbol * after the torque value.
Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS, unless other lubricants are referred to in the procedure.
To identify and install tab washers, refer to the SPM TASK 70-42-03-400-501.
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 install the LP Compressor Bleed Duct, the Booster Stage Bleed Valve and actuating mechanism, LP Compressor Stage 2.5 Vane and the right and left rod assemblies. For the other LP Compressor/Intermediate Case Module parts, refer to TASK 72-32-00-430-000 (ASSEMBLY-000).
