For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item numbers.
For standard torque data and procedures refer to SPM TASK 70-41-00-400-501, SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-410-501.
Special torque data and 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.
To identify, lubricate and install seal rings, refer to SPM TASK 70-44-01-400-501.
After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanged and attach parts. Use the correct color of the CoMat 07-038 AIR DRYING ENAMEL. Refer to SPM TASK 70-63-02-380-501.
The number for each circumferential 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 otherwise specified in the procedure.
This TASK gives the procedure to assemble the HP compressor rear cases and vanes on to the HP compressor rotor assembly. TASK 72-41-00-440-002-B00 (ASSEMBLY-002) gives the procedure to install the HP compressor front cases on to the HP compressor rotor assembly.
The practices and processes referred to in the procedure by the TASK/SUBTASK number are in SPM.
