Common Information

TASK 72-32-00-430-013-A00 LPC/Intermediate Case Module - Install The LPC Inlet Guide Vane Assembly, Assembly-013

General

This TASK gives the procedure to install the LPC inlet guide vane assembly.

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 the 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.

Lubricate all threads and abutment faces of nuts and bolts with the approved engine oils, unless other lubricants are referred to in the procedure, refer to the SPM TASK 70-64-00-640-501.

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.

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.

The No.1 strut, which is the top position strut of the fan frame assembly, is identified by the five pressure tubes on the No.1 strut leading edge.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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

1. Refer to Figure.
2. Make sure that the fan frame and fan case assembly is installed horizontally on the turnover stand. Refer to TASK 72-32-00-430-011-A00 (ASSEMBLY-011, CONFIG-001).
3. Make sure that the work mat is in position in the fan case. Refer to TASK 72-32-00-430-011-A00 (ASSEMBLY-011, CONFIG-001).
4. Use a clean cloth made moist with CoMat 01-124 ISOPROPYL ALCOHOL to clean the mating faces.
5. NOTE
  Install the LPC inlet guide vane assembly on to the LP compressor front case before the jointing compound becomes dry.
  Apply CoMat 04-004 JOINTING COMPOUND, LIGHT GRADE to the mating faces with a soft brush.
1. Refer to Figure and Figure.
2. 1. Attach the vane assembly to the front flange on the front case.
  2. Safety the vane assembly with the 12 washers (01-268) and bolts (01-265). Tighten the bolts lightly.
3. 1. Align the two locating pins of each bracket with the holes in the front case.
  2. Attach the brackets to the front flange on the front case and safety with the 34 bolts V2500-A5-72-32-93-01A-941A-D (72-32-93, 01-570).
  3. Tighten the bolts lightly.
4. Torque the 46 bolts (01-265 and 72-32-93, 01-570) to between 36 and 45 lbfin (4.00 and 5.00 Nm). UseIAE 1J12483 Socket wrench 1 off to apply the torque to the 34 bolts which attach the brackets.
1. Refer to Figure.
2. 1. Make sure that the curvic teeth on the stub shaft and the measuring stretch are clean. Clean the teeth with a clean cloth made moist with CoMat 01-124 ISOPROPYL ALCOHOL if the curvic teeth are not clean.
  2. Engage the curvic teeth of the measuring stretch with the curvic teeth of the stub shaft.
  3. Safety the measuring stretch with the set screws (part of the measuring stretch). Tighten the set screws.
3. 1. Install the dial gage on to the base pin of the measuring stretch.
  2. Calibrate the zero position of the dial gage.
  3. Remove the dial gage from the base pin.
4. Remove the workmat from the fan case.
1. Refer to Figure.
2. NOTE
  No.1 bearing axial play causes the LP stub shaft to be moveable when the module is in horizontal position. The LP stub shaft must be at the rear position in the movement range for correct measurement of AA1. The LP stub shaft moves correctly to the rear end position if you push it by sufficient force.
  Apply force of 33 lbs (15 kg) or more than to push the LP stub shaft rearwards by hand until its movement stops. Continue pushing to keep the LP stub shaft in position until step D. is completed.
3. Read the tool dimensions L and H marked on the clocking pin C (part of IAE 1J12457 Measuring stretch 1 off) and the measuring stretch.
4. NOTE
  Do steps C. to F. at 12, 3, 6 and 9 o'clock positions.
  Install the clocking pin C on to the LPC inlet guide vane through the measuring stretch hole.
5. Measure the dimension XC with the dial gage (part of the measuring stretch). Remove the clocking pin C.
6. Use the following formula to calculate the module interface dimension AA.
  AA = L - XC - H.
7. Make sure that the dimension AA is between 0.823 and 0.889 in. (20.90 and 22.60 mm).
1. Refer to Figure.

  Install the clocking pin C on to the LPC inlet guide vane through the measuring stretch hole.
5. Measure the dimension XC with the dial gage (part of the measuring stretch). Remove the clocking pin C.
6. Use the following formula to calculate the module interface dimension AA.
  AA = L - XC - H.
7. Make sure that the dimension AA is between 0.805 and 0.871 in. (20.43 and 22.13 mm).
1. Refer to Figure.
2. Install the work mat in to position in the fan case again.
3. 1. Remove the set screws which attach the measuring stretch to the stub shaft. Remove the measuring stretch.
1. Refer to Figure and Figure.
