TASK 72-41-10-440-005-A00 HPC Rotor Assembly - Final Balance The Rotor Assembly, Assembly-005

General

This TASK gives the procedure to final balance the HP compressor rotor assembly.

The procedure to measure, assemble and balance the HP compressor rotor assembly is given in the subsequent TASKS.

TASK 72-41-10-440-001 (ASSEMBLY-001, CONFIG-001) Measure the HP compressor rotor assembly parts.

TASK 72-41-10-440-002 (ASSEMBLY-002, CONFIG-001) Assemble the HP compressor rotor assembly.

TASK 72-41-10-440-003 (ASSEMBLY-003, CONFIG-001) Do a balance check of the HP compressor rotor assembly and install the blades.

TASK 72-41-10-440-004 (ASSEMBLY-004, CONFIG-001) Grind the tips of the HP compressor blades.

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 numbers.

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

For standard torque data and procedure refer to SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.

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

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 curvic teeth and mating faces 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.

All of the temporary marks made in this procedure must be removed after completion of this task.

Data to balance

The tools used in this procedure are used to adapt the HP compressor rotor assembly to the 'Schenck HL5' dynamic balancing machine. A balancing speed between 650 and 1000 rpm that gives stable and repeatable results is recommended. The best speed to use will be different for different machines. The correct RPM will usually agree with the gear ratios available. The balancing machine must turn the HP compressor rotor assembly in a clockwise direction (direction of engine turn) when seen from the rear of the engine.

NOTE

To identify consumable materials refer to the PCI.

NOTE

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