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.
Lubricate all the bolt shanks given in this procedure with CoMat 10-073 SYNTHETIC GREASE, MoDISULFIDE, Mo disulphide. Lubricate all the bolt holes with CoMat 10-072 ANTISEIZE COMPOUND (MoDISULFIDE), unless other lubricants are referred to in the procedure.
Transportation covers/blanks must be removed immediately before the installation of the components.
For the torque tightening procedures, refer to the SPM TASK 70-41-00-400-501 and SPM TASK 70-41-01-400-501.
