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 the SPM TASK 70-41-00-400-501 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 the 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 07-062 TWO-PACK EPOXY FINISH, GREY, AIRCRAFT, BS381C 693 to any damaged surface protection, joint flanges and attach parts. Use the correct color of two-pack epoxy finish and catalyst. Refer to the SPM TASK 70-38-34-300-503.

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.
