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 TASK 70-41-02-400-501.

Special torque data and assembly tolerances are included in the 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 07-012 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to TASK 70-38-06-380-501.

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.
