TASK 72-50-10-430-005 LPT Case And Rotor Assembly - Assemble The LPT Stage 5 Stator Vanes To The LPT, Assembly-005
General
Fig/item numbers 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.
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 the SPM TASK 70-63-02-380-501.
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.
Refer to TASK 72-50-00-990-501 (DESCRIPTION AND OPERATION-001) for a sectional view of the LP turbine module.
The abbreviation Intf shows an interference or tight fit. This causes REJECT IF MORE THAN to become REJECT IF LESS THAN. The abbreviation Clear shows a clearance fit.

Refer to Figure.
Check each stage 5 vane segment for total number of "+" markings on the part.
NOTE
The total number of vane segments which show each two "+" markings is limited to five parts per LPT module assembly. Make sure that not more than five vane segments each marked with two "+" symbols are installed per LPT module assembly.NOTE
Make sure that all strip seals are correctly installed in the grooves of the stage 5 vane segments.Install the three strip seals in the grooves on the right inner and outer platform of the vane segment number one. Use CoMat 10-062 ASSEMBLY FLUID.
