Common Information

TASK 72-50-00-430-001 LP Turbine (LPT) And Turbine Exhaust Case (TEC) Unit - Assemble The LPT Shaft To The LPT Case And Rotor Assembly, Assembly-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 the SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.

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

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

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.

Refer to TASK 72-50-00-990-501 for a sectional view of the LP turbine module.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

Special tools are identified in the procedure by the tool primary number.

      NOTE

      Make sure that the IAE 1F10101 Counter weights kit 1 off is installed on the IAE 1F10049 Vertical stand 1 off. Do not move the stand with the installed LP turbine case and rotor without the counterweight kit.

    1. Make sure that the locating fixture, part of the vertical stand, is in the bottom position.

      2. Remove the LP turbine shaft from the storage stand as follows:

      1. Remove the two wing nuts of the storage stand and open the two covers.

      2. Install the IAE 1J12201 Front sling 1 off to the front thread of the LP turbine shaft. Attach hoist equipment to the sling.

      3. Install the IAE 1J12202 Rear sling 1 off to the rear thread of the LP turbine shaft. Attach a second hoist equipment to the rear sling.

      4. Lift the LP turbine shaft from the storage stand.

      3. Install the LP turbine shaft to the IAE 1F10049 Vertical stand 1 off as follows:

      1. Adjust the two hoists so that the LP turbine shaft turns from horizontal to vertical with the front end down.

      2. Remove the hoist equipment and the front sling from the front end of the LP turbine shaft.

      3. Move the LP turbine shaft near the vertical stand. Engage the LP turbine shaft in the vertical stand.

      4. Lower the LP turbine shaft in to the vertical stand.

    4. Install the LP turbine shaft to the vertical stand.
