Assemble the HP Compressor Rotor Disks using IAE1P16616 by TASK 72-41-10-440-008-B00 (ASSEMBLY-008).

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.

Overhaul processes referred to in this procedure by the TASK/SUBTASK number are in SPM.

For standard torque data and procedures, refer to:

SPM TASK 70-41-00-400-501.

SPM TASK 70-41-01-400-501.

SPM TASK 70-41-02-400-501.

Special torque data is identified with the symbol * after the torque value.

Special assembly tolerances are included in this procedure.

Lubricate all threads and mating faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS, unless other lubricants are referred to in the procedure.

All the mating faces and curvic teeth must be cleaned with CoMat 01-001 SOLVENT, DELETED or CoMat 01-002 SOLVENT, DELETED. before assembly. Refer to SPM TASK 70-11-01-300-503. They must also be dry assembled unless told differently in the procedure.

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

Do a check of the interference dimensions of the Stage 3 To 8 Disk Assembly to the Stage 9 To 12 Disk Assembly. Also do a check of the Stage 9 To 12 Disk Assembly to the HPC Rear Shaft. This must be done to make sure you get the correct interference fits.

All the temporary marks made in this procedure must be removed before the engine is started.

The data found in this procedure, when used during assembly, will permit the Rotor Assembly to be assembled with all of the parts concentric to specified limits.

The following SUBTASKS can also be achieved in conjunction with the Axiam V2500 High Pressure Compressor, Rotor Component Measurement and SmartStack Assembly Process. Document No V2500-HPC-01, Revision G (last revised in August 2010). Use of other versions need to be validated by IAE.

It is important to prevent unwanted swash and run-out during this procedure. Thus, all of the rotor parts, tools and equipment used in this procedure must be kept very clean.

Run-out.

Run-out is the total movement of the measuring equipment display, in relation to a Location diameter, when a part is turned. Run-out includes eccentricity and ovality, (or out of roundness).

All of the dimensions given in this procedure in relation to run-out, refer only to eccentricity. If there is ovality, it will be necessary to correct it. To correct the ovality, get the difference between two opposite values only. The difference between these values must not be more than the total specified dimension permitted.

If there is irregular ovality, it can be necessary to make a graph of the run-out values on CoMat 02-130 POLAR GRAPH PAPER. The quantity of ovality can then be calculated.

Swash.

Swash is the total movement of the measuring equipment display, in relation to a mating face, when a part is turned.

Run-out and Swash data.

The subsequent data must be used when you measure run-out and swash, to permit the values to be put in to a computer.

All of the measured values are to be known as positive if;

the Location diameter moves radially out, and/or

the mating face moves rearwards in relation to a datum face.

This is correct if the measuring equipment display reads positive or negative values.

A minimum of nine values for run-out and swash must be read at eight equally spaced positions, for all components. The first and last values must be the same. If the first and last values are not the same, read all of the nine values again and again until the first and last values are the same.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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