TASK 72-60-43-440-001 Angle Gearbox Driven Gearshaft Assembly - Assemble The Gearshaft Assembly, Assembly-001
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.
Special torque data and assembly tolerances are included in the procedure.
Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-039 ENGINE OIL, 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 SPM TASK 70-38-21-380-501.
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.
