Common Information

TASK 72-00-50-420-004-B00 LPT Module - Install The LPT Module (Vertical) - Method 2, Installation-005 - SBE 72-0063

General

This TASK gives the procedure to install the LP Turbine Module in vertical position. Other related TASKS are:

Install the LP Turbine Module horizontal - (Method 1) by TASK 72-00-50-420-001-A00 (INSTALLATION-002), TASK 72-00-50-420-001-B00 (INSTALLATION-002) and TASK 72-00-50-420-001-C00 (INSTALLATION-002).

Install the LP Turbine Module without TEC by TASK 72-00-50-420-002 (INSTALLATION-003).

Turn the LP Turbine Module from horizontal to vertical (front end down) by TASK 72-00-50-560-001 (REMOVAL-003).

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 is identified by the symbol * after the torque valve.

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.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of air drying enamel. Refer to the SPM TASK 70-63-02-400-501.

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.

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

For lockwire data and procedures refer to the SPM TASK 70-42-05-400-501.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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