Common Information

TASK 72-45-10-440-001-A00 HPT Stage 1 Rotor Assembly - Assemble The HPT Stage 1 Rotor 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.

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 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.

To identify, lubricate and install seal rings, refer to SPM TASK 70-44-01-400-501.

The number for each radial location must be identified in a clockwise direction. Use CoMat 06-153 FELT TIP MARKER, RAPID DRYING, CoMat 06-153X FELT TIP MARKER, RAPID DRYING, FINE POINT, BLACK, TRACE ELEMENT CERTIFIED or CoMat 06-158 MARKER, EXTRA FINE POINT(BLACK). These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.

For temporary marking procedures, refer to SPM TASK 70-09-01-400-501.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

Special tools are identified in the procedure by the tool primary number.
