Common Information
TASK 72-00-45-420-001-B01 HPT Assembly - Install The HPT Assembly (Horizontal) - Method 1, Installation-001
General
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 SPM TASK 70-41-00-400-501 and SPM TASK 70-41-02-400-501.
Special torque data and assembly tolerances are included in this procedure.
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.
To identify, lubricate and install seal rings, refer to SPM TASK 70-44-01-400-501.
The number for each radial location must be identified in a clockwise direction. Use CoMat 06-153 FELT TIP MARKER, RAPID DRYING, CoMat 06-153 FELT TIP MARKER, RAPID DRYING X or CoMat 06-158 MARKER, EXTRA FINE POINT(BLACK). These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure. Refer to SPM TASK 70-09-00-400-501.
Transportation covers/blanks must be removed immediately before the installation of the components.

Install the IAE 1P16046 Removal/Installation fixture or IAE 1P16543 Removal/Installation fixture 1 off.
NOTE
Make sure when you take the measurements that the vernier does not go into the slots that are located on the hub flange.Measure the distance from the two machined areas of the fixture to the rear flange of the Stage 2 Hub. Use a depth vernier, Figure.
Check to see if the HP Turbine Rotor And Stator Assembly is in the proper running position.
Install the IAE 1P17022 Removal/installation jaws assembly 1 off.
Install the scalloped plate, of the IAE 1P16272 Adapter 1 off, to the rear inner flange of the fixture and install and tighten the bolts.

SUBTASK 72-00-45-420-058 Install the Tooling to the HPT Rotor and Stator Assembly
If the C - B calculation results in a class 9 or 10 spacer - Install a class 11 spacer.
If the C - B calculation results in a class spacer that is less than 9 - Install a class 10 spacer.
If the C - B calculation results in a class 13 or 14 spacer - Install a class 12 spacer.
If the C - B calculation results in a class spacer that is more than 14 - Install a class 13 spacer.
Use the guidelines for correct bearing tolerances that follow so you can meet the final assembly check:
Usually, the necessary spacer will be a class 11 or 12. After you subtract dimension B from dimension C, if a different class is necessary, check the measurements and do the calculation again.
Subtract dimension B from dimension C and the result will be the required No. 4 bearing spacer dimension.
After you have machined the spacer, mark the new class number at the location shown in Figure. Cross off old class marking. Refer to SPM TASK 70-09-00-400-501. Use vibration peen method. Remove high metal.
If the correct class spacer is not available, you can machine a larger (numerically higher) class spacer to a smaller (numerically lower) class spacer as follows:
Use the table to find the correct class of the spacer, refer to Figure.
Position the spacer with the IAE 1P16470 Drift 1 off. Refer to Figure.
Apply CoMat 10-129 ANTI-SEIZE PASTE to the mating surface on the HPC rear hub, Figure. Wipe off excess paste.
SUBTASK 72-00-45-420-059 Get the No. 4 Bearing Spacer Dimension
Refer to Figure.
Remove the pin and remove the cover from the IAE 1P16040 Heater 1 off.

CAUTION
REMOVE THE THERMOCOUPLE FROM THE HEATER BEFORE THE HP TURBINE ROTOR AND STATOR ASSEMBLY IS INSTALLED. IF THIS IS NOT DONE, DAMAGE TO THE THERMOCOUPLE MAY RESULT.Turn the HP Turbine Rotor And Stator Assembly to the front end down position and lower onto the heater until the case flange rests on the heater flange.
Attach the heater to the IAE 6F10027 Heater control unit 1 off. Heat the HP turbine rotor and stator assembly to 400 °F (204 °C).
SUBTASK 72-00-45-420-060 Install the HP Turbine Rotor and Stator Assembly onto the Heater

NOTE
This cover is used to prevent damage to the Rotor Assembly when the tools are installed to torque the bearing retaining nut.Install the IAE 1P17509 Protective cover 1 off to the rear flange of the HP Turbine Rotor And Stator Assembly.
NOTE
Bake step for the anti-galling compound after it has been applied is not necessary.
The bearing retaining nut must be silver plated when you install or remove the nut more than five times or engine operation has occurred.
Apply CoMat 10-031 ANTI-GALLING COMPOUND to the mating surface of the bearing retaining nut ENGINE-ATTACH PARTS & FITTINGS-HP SYSTEM (72-40-00, 04-020).
Engage the slots of the retaining nut with the teeth of the IAE 1P16284 Hand wrench 1 off and install the bearing nut.
Install IAE 1P17023 Torque adapter 1 off in the slots of the bearing retaining nut.
Install the scalloped plate of the IAE 1P16272 Adapter 1 off over the puller rod and into the rear flange of the fixture.
Install the IAE 1P16341 Torque adapter 1 off over the hydraulic cylinder and engage the four pins in the flange holes of the torque adapter.
Connect the IAE 1F10026 Hydraulic hand pump 1 off to the hydraulic cylinder.
NOTE
Keep the hydraulic load applied when you move the torque adapter to a new set of holes.If necessary to get the correct torque, remove the torque adapter and position the adapter into a new set of four holes in the IAE 1P17023 Torque adapter to provide the proper clearance with the hydraulic cylinder connector.
Install a torque wrench into the rear of the torque adapter and torque the retaining nut to 500 lbfin (56.493 Nm).
Loosen the wingnuts on the four clamp assemblies on the IAE 1P17025 Adapter or IAE 1P17047 Adapter.

CAUTION
TURN THE ADAPTER TO LOCATE THE SLOTS WITH THE LOCKS BETWEEN THE TEETH OF THE ADAPTER. MAKE SURE THE SLOTS AND THE TEETH OF THE ADAPTER ARE ALIGNED TO PREVENT DAMAGE TO THE SIDES OF THE SLOT.Lift the adapter in position and engage the teeth of the adapter with the slots of the Stage 2 Turbine Hub.
