Common Information

TASK 72-32-00-030-006-D00 LPC/Intermediate Case Module - Remove The LPC Booster Stage Assembly To Gain Access To The Front Bearing Compartment Area, Disassembly-006

General

This TASK gives the procedure to remove the LP compressor booster stage assembly from the LP compressor/intermediate case module to gain access to the front bearing compartment area.

This procedure uses a method that does not require separation of the HP system module and the external gearbox module from the LP compressor/intermediate case module.

Where this TASK is used for removal of the LP compressor booster stage assembly, it is recommended to use TASK 72-32-00-430-010-D00 (ASSEMBLY-010, CONFIG-004).

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.

NOTE

Special tools are identified in the procedure by the tool primary number.
