TASK 72-00-50-420-002 LPT Module - Install The LPT Module Without Turbine Exhaust Case (TEC) (Horizontal) - Method 2, Installation-003
General
This TASK gives the procedure to install the LP Turbine Module without TEC in horizontal 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 (vertical) - Method 2 by TASK 72-00-50-420-004-A00 (INSTALLATION-005) and TASK 72-00-50-420-004-C00 (INSTALLATION-005).
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 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 value.
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.
After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to SPM TASK 70-38-21-380-501.
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 lockwire data and procedures, refer to SPM TASK 70-42-05-400-501.
