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 standard torque data and procedures, refer to SPM TASK 70-41-00-400-501, SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.

Special torque data and assembly tolerances are included in the procedure.

Lubricate all threads and touch 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 the SPM TASK 70-44-01-400-501.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and parts used to attach. Use the correct color of the air drying enamel. Refer to SPM TASK 70-63-02-380-501.
