Common Information
TASK 72-41-30-440-007-B00 HPC Front Case And Vane Assembly - Install The Stage 6 Variable Stator Vanes, Assembly-007
General
Fig/item numbers in parentheses in the procedure agree with those used in the EIPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the EIPC.
For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.
The number for each radial location must be identified in a clockwise direction. These start as the engine top position when you look from the rear of the engine, unless stated differently in the procedure.
Refer to Figure for a sectional view of the HP compressor front case.
After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and parts used to attach. Use the correct color of the air drying enamel. Refer to the SPM TASK 70-63-02-380-501.
This TASK gives the procedure to install the stage 6 stator vanes. The subsequent TASKS give the procedure to assemble the HP compressor front cases.
