TASK 72-32-00-430-010-D00 LPC/Intermediate Case Module - Install The LPC Booster Stage Assembly onto The LPC/Intermediate Case Module, Assembly-010
General
This TASK gives the procedure to install the LP compressor booster stage assembly onto 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-D00 (DISASSEMBLY-006, CONFIG-004) 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 onto 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.
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.

NONESafety Requirements
NONEProcedure
Make sure that the engine is in a horizontal position. If not, turn the engine from the vertical to the horizontal position. Refer to TASK 72-00-40-560-002 (INSTALLATION-002) or TASK 72-00-50-560-004 (INSTALLATION-013).
SUBTASK 72-32-00-430-361 Make sure that the Engine is in a Horizontal Position
NOTE
The retaining protector is installed in TASK 72-32-00-030-006-D00 (DISASSEMBLY-006, CONFIG-004).Remove the retaining protector (IAE 1J12182 Retaining protector) from the LPC stub shaft.
Install the three aligning pins (part of the IAE 1J12106 Aligning pin set 1 off) into three of 24 nuts of the rotor center shaft through the holes B.
Install IAE 1J12026 Turning handle 1 off onto the stub shaft with the two wing bolts and washers (part of the turning handle).
Adjust the angular position of the stub shaft.
SUBTASK 72-32-00-430-362 Adjust the Angular Position of the LPC Stub Shaft
Refer to Figure.
Attach the first hoist to link (part of IAE 1J12108 Sling adapter 1 off) and lift up.
Attach the second hoist to the shackle (part of IAE 1J12105 Cantileer sling 1 off).
SUBTASK 72-32-00-430-363 Prepare the Cantilever Sling and the Sling Adapter (Sling Assembly)
Install the IAE 1J12505 0AM53 heater 1 off to the LPC assembly.
Connect the cables of the local heater to the IAE 6F10027 Heater control unit 1 off.
NOTE
Install the LPC assembly to LPC stage 2.5 stator assembly (Stage 2.5 Stator) before the front flange of the LPC assembly becomes cool and the jointing compound becomes dry.Increase the temperature of the LPC assembly, Figure.
Use a clean cloth made moist with CoMat 01-124 ISOPROPYL ALCOHOL to clean the mating faces.
Apply CoMat 04-004 JOINTING COMPOUND, LIGHT GRADE to the mating faces with a soft brush.
Apply jointing compound to the mating faces of the stage 2.5 stator, Figure.
Adjust the position of the LPC stage 1.5-2.5 disk to align the top position of the sling adapter with the correlation mark * on the LPC stage 1.5-2.5 disk, Figure.
Slowly lift the two hoists equally at the same time until the LPC assembly is clear of the storage stand, Figure.
Remove the LPC assembly from the storage stand.

WARNING
DO NOT TOUCH THE LPC ASSEMBLY WITHOUT PROTECTIVE GLOVES.
WARNING
HOT PARTS CAN CAUSE REDDENING AND BLISTERING OF THE SKIN IF THE HANDS ARE NOT PROTECTED.
WARNING
IMMERSE THE CONTACTED AREA IN COLD WATER FOR 10 MINUTES IF THE SKIN IS BURNED. IMMEDIATELY GET MEDICAL ATTENTION IF PAIN OR BLISTERING PERSISTS.Install the sling assembly to the LPC assembly.
