TASK 72-41-10-040-001-A00 HPC Rotor Assembly - Disassemble The Rotor Assembly, Disassembly-001

General

This TASK gives the procedure to disassemble the HP compressor rotor assembly. It includes the procedure to measure the seal and stator path diameters and the blade lengths before removal.

Make sure the tip check and seal check equipment has been calibrated before you use it. Refer to the Illustrated Tools and Equipment Manual, Pub ref ITE-V2500-1IA.

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.

Apply the approved penetrating oil before the removal of threaded parts and parts with an interference fit. Let the parts soak before removal. For the approved oils and procedures, refer to the SPM TASK 70-64-00-640-501.

If it is necessary to remove blades from the disks they must be correlated to the disk.
