TASK 72-32-00-430-010-C00 LPC/Intermediate Case Module - Install The LPC Booster Stage Assembly On To The LPC/Intermediate Case Module, Assembly-010
General
This TASK gives the procedure to install the LP compressor booster stage assembly on to the LP compressor/intermediate case module on which the HP system module and the external gearbox module are installed.
Where TASK 72-32-00-030-006-C00 (DISASSEMBLY-006, CONFIG-003) is used for removal of the LP compressor booster stage assembly, it is recommended to use this TASK for installation of the LP compressor booster stage assembly on to the LP compressor/intermediate case module.
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 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.
