Common Information

TASK 72-50-50-440-001-A00 Turbine Exhaust Case (TEC) Assembly - Assemble The TEC Assembly, Assembly-001 - Pre SBE 72-0063

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 the SPM TASK 70-41-00-400-501 and SPM TASK 70-41-02-400-501.

Special torque data and assembly tolerances are included in the procedure.

Lubricate all threads and abutment face 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 the SPM TASK 70-44-01-400-501.

After assembly apply CoMat 07-012 AIR DRYING ENAMEL air drying touch-up enamel to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to the SPM TASK 70-38-06-380-501.

The number for each radial location must be identified in a clockwise direction. These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.

Transportation covers/blanks must be removed immediately before the installation of the components.

For oil service tube installation reference the SPM TASK 70-41-00-400-501 for general torque tightening procedures.

NOTE

To identify the consumable materials refer to the PCI.

Procedure

    1. SUBTASK 72-50-50-440-051 Install the Turbine Exhaust Case on the Build Stand

    1. Install IAE 1F10178 Storage and Turnover adapter 1 off on the trunnion plate of IAE 1M14110 Turnover stand 1 off. Attach with the bolts. Put the trunnion plate in vertical position.

    2. Install IAE 1F10042 Engine lift eye rear bare 1 off on IAE 1F10041 TEC lift adapter 1 off. Attach with the bolts.

    3. Attach the TEC bare engine adapter to the engine mounts of the turbine exhaust case.

    4. Lift the turbine exhaust case. Align the front flange of the turbine exhaust case with the flange of the adapter. Attach with the bolts.

    5. Turn the handle of the build stand and put the turbine exhaust case horizontally with the rear face to the top.

    2. SUBTASK 72-50-50-440-052- Install the Outer Race of the No. 5 Bearing

    1. Refer to: Figure and Figure

    2. Install the retainer ring over the outer race of the No. 5 bearing. Put the lugs on the rear flange of the outer race in to the slots on the front flange of the retainer ring.

    3. Put the outer race and the retainer ring to the flange of the No. 5 bearing housing with the outer race forward. Align the offset holes on the retainer ring with the holes on the flange of the No. 5 bearing housing.

    4. Install IAE 1F10151 Locating pin 4 off through the holes of the retainer ring and put in to the bolt holes on the rear flange of the No. 5 bearing housing.

    5. Install IAE 1F10152 Removal/installation fixture 1 off on the rear flange of the turbine exhaust case. Safety with the three knobs.

    6. Operate the slide hammer of the fixture to put the outer race and the retainer ring in position.

    7. Remove the locating pins and the fixture.

    8. Install the upper and lower deaerators on the retainer ring. Align the holes.

    9. Install the eight bolts which attach the deaerators and the retainer ring to the flange of the turbine exhaust case. Torque to 85 to 105 lbfin (10 to 12 Nm).

    3. SUBTASK 72-50-50-440-055- Connect the Oil Scavenge Tube of the No. 5 Bearing

    1. Refer to: Figure

      NOTE

      Make sure mating surfaces are completely free from debris, grease or oil. Use shop inspection mirror or adequate tool to view mating surfaces.

      NOTE

      Prior to fit make sure no internal blockages, carbon/coke or debris exist on the ID of the parts (tubes, jets and fittings).

      NOTE

      Fit oil scavenge tube to mating surface (without seal) in case. Make sure there is a 0.001 in. (0.0254 mm) gap maximum after tightening tube for fit check. Fit up between case face and tube flange (Reference TASK 72-50-53-200, step 28).

      Prior to final assembly:

    2. Install ENGINE-EXHAUST CASE AND FITTINGS (72-50-53,01-700) metallic seal 1 off to the flange of the oil scavenge tube.

    3. Install the three bolts which attach the oil scavenge tube to the No. 5 bearing compartment. Torque the bolts in increments of 25 lbfin (2.82 Nm) to 101.784 lbfin (11.5 Nm).

    4. Install the bracket on the inner support of the case. Install the two bolts and locknuts and torque to 101.784 lbfin (11.5 Nm).

    5. Install the clamp to the oil scavenge tube. Attach the clamp to the bracket with the bolt and the locknut. Torque to 39.828 lbfin (4.5 Nm).

    6. Install and align the bracket to the external flanges of the oil scavenge tube and case.

    7. Install the two bolts and locknuts which attach the bracket to the external flange of the case. Torque to 101.784 lbfin (11.5 Nm).

    8. Install the bolts and locknuts which attach the oil scavenge tube to the bracket. Torque to 101.784 lbfin (11.5 Nm).

    4. SUBTASK 72-50-50-440-056- Install the Tube Union

    1. Refer to: Figure

    2. Install ENGINE-TURBINE EXHAUST CASE ASSEMBLY (72-50-50,01-330) oil seal 1 off on the tube union. Make sure that the oil seal is installed in the correct position.

    3. Install the tube union on the turbine exhaust case. Torque to 203.5 lbfin (23 Nm).
