TASK 71-00-02-400-025 (A1/A5-PPBU) - Install The Common Nozzle Assembly, Installation-025
General
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 70-41-00-400-501 and SPM TASK 70-41-02-400-501.
Special torque data is included in the procedure.
Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-094 ANTI-SEIZE COMPOUND, PURE Ni-SPECIAL, unless other lubricants are referred to in the procedure.
The number for each radial location is 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 installation of the components.
Make sure the upper strut recess of the Common Nozzle Assembly (CNA) is at the top center.

Remove the IAE 1N20001 Common nozzle fixture 1 off with the attached CNA Common Nozzle Assembly (CNA) (78-11-11, 01-010) from the IAE 1N20004 Common nozzle dolly 1 off with a suitable lifting device.
NOTE
Access to some of the CNA fasteners is difficult. Access to these fasteners can be improved by the use of a standard 5/16 in. (7.93 mm) wrench modified to fit the contour of the CNA.Carefully move the CNA to the rear of the engine. Make sure that the CNA does not touch the exhaust cone Engine Exhaust Cone And Plug (78-11-12, 01-010).
Pre SBN 78-0208: Install the bolts Common Nozzle Assembly (CNA) (78-11-11, 01-020), washers Common Nozzle Assembly (CNA) (78-11-11, 01-025) and nuts Common Nozzle Assembly (CNA) (78-11-11, 01-030) to attach the CNA Common Nozzle Assembly (CNA) (78-11-11, 01-010) to the engine flange. Do not fully torque the nuts until they are all installed. Do not install washers on the bolts which go through the EGT harness brackets on the engine flange.
SBN: 78-0208: Install the bolts Common Nozzle Assembly (CNA) (78-11-11, 01-020) and washers Common Nozzle Assembly (CNA) (78-11-11, 01-025) to attach the CNA Common Nozzle Assembly (CNA) (78-11-11, 01-010) to the engine flange.
