TASK 72-41-30-440-003-C00 HPC Front Case And Vane Assembly - Install The Variable Inlet Guide Vanes, Assembly-003 - SBE 72-0564 And SBE 72-0571 (Select One Production Standard)

General

Install the HP Compressor Stage 4 and 5 Rotor Path Rings and Stage 6 Rotor Ring Segments TASK 72-41-30-440-001-C00 (ASSEMBLY-001).

Measure and then machine Stage 6 Stator Vanes and the Stage 4, 5 and 6 Rotor Path Rings TASK 72-41-30-440-002-B00 (ASSEMBLY-002).

Install the Stage 3 VSV TASK 72-41-30-440-004-C00 (ASSEMBLY-004).

Install the Stage 4 VSV TASK 72-41-30-440-005-C00 (ASSEMBLY-005).

Install the Stage 5 VSV TASK 72-41-30-440-006-C00 (ASSEMBLY-006).

Install the Stage 6 Stator Vanes TASK 72-41-30-440-007-B00 (ASSEMBLY-007).

Install the VIGV and the Stage 3 to 5 Bridge Pieces TASK 72-41-30-440-008-C00 (ASSEMBLY-008).

Measure the HP Compressor Front Cases TASK 72-41-30-440-009-C00 (ASSEMBLY-009).

Disassemble the HP Compressor Front Cases TASK 72-41-30-440-010-C00 (ASSEMBLY-010).

Check and Set VSV System with Optimised Build and Setting Clearances 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 PARTS 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.

This task gives the procedure to install the HP Compressor variable inlet guide vanes (VIGV) 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 HP Compressor front cases.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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

    The 38 actuating levers HPC Variable Stator Vane Actuation System (72-41-34, 02-100) go at the positions 1 to 9, and 12 to 40.
  2. NOTE
    The guide vane actuating levers must be parallel with the casing center line when you torque the bolts. This is the null position.
    Install the 38 bolts HPC Variable Stator Vane Actuation System (72-41-34, 02-102) and two bolts HPC Variable Stator Vane Actuation System (72-41-34, 02-142) to attach the actuating levers to the guide vanes. The two bolts HPC Variable Stator Vane Actuation System (72-41-34, 02-142) go at the positions 10 and 11. Torque the bolts to 85 to 105 lbfin (10 to 12 Nm).
  3. Do a check for correct assembly of the levers.
    Make sure that the spindles fully engage into the levers, there is no gap permitted between the lever and spindle mating faces.
    Make sure that the lever balls do not protrude out of their actuating ring holes.
    Make sure that the vane trailing edges point rearward.
  4. Remove the rigging pins from the guide vane actuating ring.
