TASK 72-50-00-030-801
1 . General.
A.This procedure gives instructions to disassemble the high pressure turbine (HPT) module. Refer to Figure 501.
B.This procedure starts with the HPT module on the 11C3010   build-up fixture. Refer to Figure 502.
C.Make sure that the engine assembly/sub-assembly/module has the correct support at all times to prevent injury to personnel or damage to engine parts.
D.Before you do this procedure, read the assembly and disassembly techniques section. Refer to TASK 70-10-00-800-009 (ASSEMBLY AND DISASSEMBLY TECHNIQUES).
E.Make sure that you follow the instructions carefully and know the special tools usage before you disassemble the HPT module.
F.All directions are aft looking forward (ALF), unless specified differently.
  G.If an axisymmetric rotating part with a visible crack through the axial or radial thickness of the part feature is found during the disassembly procedure, then the mating Life Limited Part(s) (LLP) can be affected. The mating LLP must be considered not serviceable and not repairable.
  NOTE:
Typical axisymmetric parts are disks, spools, blisks, seals, shafts, retainers, and other rotating structures.
  NOTE:
Contact GE Aerospace with part details of the cracked part and mating LLP with the Inquiries Widget on the https://my.geaerospace.com/ portal.

1Attach an overhead hoist to the hoist rings (item 8).
2Align the cutout in the base (item 17) with the split-line gap of the aft stage 2 blade retainer.
NOTE:
The cutout will give access for the 9429M68   retaining ring tool set.
3Lower the base (item 17) on the aft stage 2 blade retainer.
NOTE:
The stage 2 ring (item 16) that is attached to the base (item 17) will be on the aft stage 2 blade retainer.
(c)Install the hydraulic cylinder (item 7) on the shaft of the push-pull plate (item 4).
(d)Attach the nut (item 14) to the shaft on the push-pull plate (item 4).
(e)Connect the hydraulic pump to the hydraulic cylinder (item 7) of the 11C3017   install/remove fixture.
(f)Put the valve on the hydraulic pump in the PUSH position.
(g)Operate the hydraulic pump three to five full strokes to prevent free movement of the 11C3017   install/remove fixture.
(h)Make sure that the stage 2 ring (item 16) of the 11C3017   install/remove fixture is aligned with the aft stage 2 blade retainer.
CAUTION:
DO NOT APPLY MORE THAN 10,000 PSIG (68950 KPA) TO THE HYDRAULIC CYLINDER (ITEM 7) OF THE 11C3017   INSTALL/REMOVE FIXTURE OR YOU CAN CAUSE DAMAGE TO THE AFT STAGE 2 BLADE RETAINER.
(i)Apply a maximum pressure of 10,000 psig (68950 kPa gage) to deflect the aft stage 2 blade retainer. When you apply the pressure, the 11C3017   install/remove fixture will apply downward pressure on the aft stage 2 blade retainer. Apply sufficient pressure to permit free movement of the aft retainer ring.
(j)Compress the aft retainer ring (150B7) as follows:
1Install the 9429M68   retaining ring tool set in the holes on the ends on the aft retainer ring.
2Adjust the tool set to move the aft retainer ring in (compressed position) below the hook of the stage 2 disk.
NOTE:
This will permit the stage 2 blade retainer to be removed.
3Compress the aft retainer ring completely below the hook and install a clip (item 19) of the 11C3017   install/remove fixture around each end of the aft retainer ring end gap.
NOTE:
The clip will hold the aft retainer ring aft and inboard in the hook of the stage 2 disk.
4Install the remaining clips (item 19) around the aft retainer ring approximately 30 degrees apart.
(k)Remove the 9429M68   retaining ring tool set.

N.Remove the HPT rotor stage 2 blades (stage 2 blades) (01-110 , 72-53-00) (SIN 150B0) or (01-111 , 72-53-00) (SIN 150B0) or (01-112 , 72-53-00) (SIN 150B0) or (01-113 , 72-53-00) (SIN 150B0) or (02-110A , 72-53-00) (SIN 150B0) from the stage 2 disk. Refer to Figure 515 and do as follows:
(1)If necessary, use the C05-003   pen to put a mark on each dovetail slot of the stage 2 disk and each dovetail of the stage 2 blades in relation to the blade position in the stage 2 disk. Begin the marks with the 1-1 slot (marked on the disk post) and move CW, ALF.
NOTE:
If the HPT rotor assembly will be completely disassembled, it is not necessary to put marks on the dovetails of the stage 2 disk and stage 2 blades.
(2)Remove the stage 2 blades and dampers (01-120 , 72-53-00) (SIN 150B8) or (02-120 , 72-53-00) (SIN 150B8) from the stage 2 disk as follows:
(a)Move a blade axially aft a small distance until you can move the adjacent blade axially aft.
CAUTION:
BE CAREFUL NOT TO LET THE STAGE 2 BLADE DAMPERS FALL INTO THE ENGINE OR DAMAGE CAN OCCUR.
(b)Continue this procedure until you can remove a blade and a stage 2 damper.
NOTE:
As this procedure is done, each adjacent blade will move further aft than the previous one until a blade can be removed from the disk.
(c)Remove the remaining stage 2 blades and dampers.
(d)Put all the stage 2 blades in the 11C3015   blade container, airfoils facing down.
(3)Discard the stage 2 blade dampers (01-120 , 72-53-00) (SIN 150B8) or (02-120 , 72-53-00) (SIN 150B8).
