Common Information
TASK 72-41-30-440-004-C00 HPC Front Case And Vane Assembly - Install The Stage 3 Variable Stator Vanes, Assembly-004 - SBE 72-0560 (SelectOne Retrofit And Production Standard), SBE 72-0564 And SBE 72-0571 (Select One Production Standard)
General
This task gives the procedure to install the stage 3 variable stator vanes (VSV) for: The engines which have SBE 72-0560 (A5 Standard, SelectOne(TM) Retrofit Standard) incorporated or the engines which have SBE 72-0560, SBE 72-0564, SBE 72-0571 and SBE 72-0573 (SelectOne(TM) Production Standard) incorporated. The subsequent TASKS give the procedure to assemble the HP Compressor front cases.
Install the Stage 4 and 5 Rotor Path Rings and Stage 6 Rotor Ring Segments by TASK 72-41-30-440-001-C00 (ASSEMBLY-001).
Measure and then machine the Stage 6 Stator Vanes and the Stage 4, 5 and 6 Rotor Path Rings by TASK 72-41-30-440-002-B01 (ASSEMBLY-002).
Install the VIGV by TASK 72-41-30-440-003-C00 (ASSEMBLY-003).
Install the Stage 4 VSV by TASK 72-41-30-440-005-C00 (ASSEMBLY-005).
Install the Stage 5 VSV by TASK 72-41-30-440-006-C00 (ASSEMBLY-006).
Install the Stage 6 Stator Vanes by TASK 72-41-30-440-007-B00 (ASSEMBLY-007).
Install the VIGV and the Stage 3 to 5 Bridge Pieces by TASK 72-41-30-440-008-C00 (ASSEMBLY-008).
Measure the HP Compressor Front Cases by TASK 72-41-30-440-009-C00 (ASSEMBLY-009).
Disassemble the HP Compressor front cases by TASK 72-41-30-440-010-C00 (ASSEMBLY-010).
Check and Set VSV System with Optimised Build and Setting Clearances - SBE 72-0400 by TASK 72-41-30-440-011-C00 (ASSEMBLY-011).
Fig/item numbers in parentheses in the procedure agree with those used in the EIPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the EIPC.
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 70-41-01-400-501 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 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 colour of the air drying enamel. Refer to SPM TASK 70-63-02-380-501.
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.
Refer to Figure for a sectional view of the HP Compressor front case.
The Fits and Clearances, NEW PART DIMENSIONS and REJECT IF MORE THAN columns will be used by most operators. This permits the full use of the maximum wear allowance and a reduction in the number of parts which are rejected, is possible.
As long as REJECT IF MORE THAN columns do not include reject values, NEW PART DIMENSIONS do not have to be measured before assembly, as there are no reject-if criteria. Values are only valid for new parts, not for worn parts.
The column WORN PART DIMENSION (Non-select) is included for operators who want to have full interchangeability. If this column is used an increase in the number of parts which are rejected is possible.
After the part has been in service for some time the REJECT IF MORE THAN and WORN PART DIMENSIONS could be changed. The operator must tell IAE and if agreed the manual will be changed.
The abbreviation Intf shows an interference or tight fit. This causes REJECT IF MORE THAN to become REJECT IF LESS THAN.
The abbreviation clear shows a clearance fit.

It is not necessary to lubricate the stage 3 locations with CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R) during this SUBTASK.If all lever arm holes are within 0.4843 in. (12.300 mm) or less in the largest diameter, continue with Step.
If one or more lever arm hole is above the limits reject the part and continue with a serviceable part.
NOTE
"If the measurement has been previously accomplished or if a new part is installed then TASK 72-41-34-200-006-D00, Step 3.B can be skipped."
Measure the 16 lever arm holes in each of the upper or lower VIGV actuating rings.
If all lever arm balls are within 0.4768 in. and 0.4787 in. (12.110 mm and 12.160 mm), continue with Step.
If any lever arm ball is above the limits reject the part and continue with a serviceable part.
NOTE
"If the measurement has been previously accomplished or if a new part is installed then TASK 72-41-34-200-004-B00, Step 15.C can be skipped."
Measure the 32 actuating lever arm balls.
The position information given in this procedure indicates that you must look from the front to the rear of the module.
Set the stage 3 upper actuating ring adjacent to the stage 3 stator vane at the positions 1 to 16.
Put the stage 3 upper actuating ring HPC Variable Stator Vane Actuation System (72-41-34, 03-440) into position on the upper half HP Compressor front case. Install three of IAE 1R18423 Rigging pin 3 off or IAE 1R18893 Riggingpin 3 off to attach the stage 3 upper actuating ring to the upper half HP Compressor front case.
Install the stage 3 upper actuating ring on to the upper half HP Compressor front case.
NOTE
The position information given in this procedure indicates that you must look from the front to the rear of the module.
Set the stage 3 lower actuating ring adjacent to the stage 3 stator vane at the positions 17 to 32.
Put the stage 3 lower actuating ring HPC Variable Stator Vane Actuation System (72-41-34, 03-540) into position on the lower half HP Compressor front case. Install three of IAE 1R18423 Rigging pin 3 off or IAE 1R18893 Riggingpin 3 off to attach the stage 3 lower actuating ring to the lower half HP Compressor front case.
Install the stage 3 lower actuating ring on to the lower half HP Compressor front case.
NOTE
Install the two stage 3 actuating levers HPC Variable Stator Vane Actuation System (72-41-34, 03-140) to the position 8 and 9 and the two bolts HPC Variable Stator Vane Actuation System (72-41-34, 03-142) to the actuating levers.
Install the three stage 3 actuating levers HPC Variable Stator Vane Actuation System (72-41-34, 03-120) to the position 21,22 and 25 and the three bolts HPC Variable Stator Vane Actuation System (72-41-34, 03-122) to the actuating levers.
Install the 27 stage 3 actuating lever HPC Variable Stator Vane Actuation System (72-41-34, 03-100) to the position 1 to 7, 10 to 20, 23 to 24 and 26 to 32 and the 27 bolts HPC Variable Stator Vane Actuation System (72-41-34, 03-102) to the actuating levers.
NOTE
The stage 3 actuating levers must be parallel with the casing centre line when you torque the bolts. This is the null position.

CAUTION
MAKE SURE THAT THE VANE SPINDLE IS FULLY ENGAGED INTO THE LEVER AND THAT THE VANE TRAILING EDGE POINTS REARWARD. THIS WILL HELP TO PREVENT DAMAGE TO THE ENGINE.Install the 32 guide vane actuating lever on the spindles of the guide vanes and in to their locations in the actuating ring.
NOTE
The position information given in this procedure indicates that you must look from the front to the rear of the module.
Install the stage 3 stator vane actuating levers.
Put the two brackets HPC Variable Stator Vane Actuation System (72-41-34, 03-800) in position on the stage 3 lower actuating ring HPC Variable Stator Vane Actuation System (72-41-34, 03-540).
Install the two bolts HPC Variable Stator Vane Actuation System (72-41-34, 03-798) and two self locking nuts HPC Variable Stator Vane Actuation System (72-41-34, 03-796) to attach the brackets to the stage 3 lower actuating ring.
Install the drive bracket.
