        The SUBTASK references which follow are in TASK 72-41-30-440-011-B00 (ASSEMBLY-011, CONFIG-002).

        Follow the procedure in TASK 72-41-30-440-011-B00 (ASSEMBLY-011, CONFIG-002) when specified and this SUBTASK.

        The clearances must agree with checking limits in Table 1.

      1. During the clearance checking procedure it could be necessary to lubricate the applicable areas of a particular stage of the VSV mechanism. Use CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R), refer to TASK 72-41-30-440-011-B00, SUBTASK 72-41-30-440-211.

      3. Measure the clearance for each stage between each centralizing pad, compensating block housing pad and the contact surface of the HP compressor front case.

      1. Install all the build pins for each stage, refer to TASK 72-41-30-440-011-B00, SUBTASK 72-41-30-440-209. The build pins must stay in the installed position throughout this procedure for each stage in turn.

      2. Measure and make a record of the clearance and the location of each stage. During the procedure the feeler gauge(s) must stay in position as each stage is checked in turn. A clearance of zero is acceptable.

      3. NOTE

        If you check the clearance with a feeler gauge in an axial position it will give large errors.

        Use feeler gauge(s) between each pad and circumferentially along the length of the actuating ring. Use the positions for the feeler gauges given in Figure.or the left side of the HP compressor case and Figure.or the right side of the HP compressor case.

      4. Check the clearance at the next circumferentially adjacent pad and the remaining pad clearances until all the eight pad clearances are measured for each stage. Use the procedure in steps (2) and (3).

      5. Add the eight clearances for each stage and refer to the limits below which gives the total clearance for each stage and for each maximum clearance.

      6. NOTE

        The procedure to set the pad clearances is given in TASK 72-41-30-440-011-B00, SUBTASK 72-41-30-440-210.

        If the clearances for each stage are more than the limits given in the following table of limits (Table 1) then the particular connector must be removed and the actuating ring must be checked for misalignment marks. Refer to the checking procedure for the correct installation of the dowels given in TASK 72-41-30-440-011-B00, SUBTASK 72-41-30-220-446.

        If marks are seen then it could be possible to meet the limits in table 1 by re-installing the connectors and rechecking the clearances. Use the above procedure to re-check the clearances so they are within the limits of table 1.

        If marks are not seen then the stage must have the pad clearances reset from the start of the procedure, that is, as given in TASK 72-41-30-440-011-B00 (ASSEMBLY-011, CONFIG-002).

      2. Replace the nut if the maximum specified torque load is reached before the split cotter pin hole and the nut slot are aligned.

    3. Install the split cotter pin, refer to Figure.or the acceptable conditions.

    4. Discard used split cotter pins. Only use new split cotter pins.

    29. SUBTASK 72-41-00-440-135 Do a Check on the Stator Vanes Angular Travel

    1. NOTE

      This procedure is to make sure that the full vane angular travel is satisfactory on each stage.

      Remove all the rigging pins installed in Step.

    2. Rotate the crankshaft assembly to the low speed position - the stator vanes are in the closed position. At the rigging pin bracket on each stage of VSV install a rigging pin. Make sure the rigging pins go in to the HP compressor front case.

    3. Remove the rigging pins installed in step B.

    30. SUBTASK 72-41-00-440-136 Remove the Protective Cover from the HP Compressor Assembly

    1. Remove IAE 1R18252 Protective cover or IAE 1R19552 Protective cover from the HP compressor assembly.

    31. SUBTASK 72-41-00-440-137 Measure the Position of the HP Compressor Rear Shaft

    1. Refer to Figure.

      2. Install the IAE 1R18251 Axial measuring fixture 1 off on to the HP compressor assembly.

      1. Use the correct lifting equipment and lift the axial measuring fixture above the HP compressor assembly.

      2. Carefully lower the axial measuring fixture on to the HP compressor rear shaft and outer case. Do not let the fixture damage the HP compressor rear shaft and outer case as it is being lowered on to them.

      3. Lower the axial measuring fixture until its front flange touches the rear flange of the HP compressor rear outer case. Align the six bolt holes in the front flange of the fixture with six bolt holes in the rear flange of the HP compressor rear outer case.

      4. Install the six bolts, six nuts and twelve washers, part of the axial measuring fixture, through the aligned six holes.

      5. Tighten the six nuts.

      6. Remove the lifting equipment.

      3. Adjust the position of the bush, part of the axial measuring fixture.

      1. Turn the three bolts identified D, until the bush touches the HP compressor rear shaft at flange E. Make sure the bush touches the flange squarely.

      4. Measure the gap between the pins A and B.

      1. Install the IAE 1R18294 Clock holder 1 off on to the axial measuring fixture at pin A.

      2. Align the plunger of the dial gage, parts of the clock holder, on the head of pin A.

      3. Apply a load to the dial gage to turn the dial gage needle two revolutions.

      4. Set the dial gage to zero.

      5. Move the clock holder on the axial measuring fixture and carefully align the plunger of the dial gage on pin B.

      6. Write down and record the value shown on the dial gage. This should be 0.023 to 0.068 in. (0.58 to 1.73 mm).

      5. Remove the axial measuring fixture.

      1. Install the correct lifting equipment as given in Step.

      2. Remove the six bolts, six nuts and twelve washers which attach the axial measuring fixture to the HP compressor rear outer case rear flange.

      3. Remove the axial measuring fixture. Do not let the fixture damage the HP compressor rear shaft as it is removed.

    32. SUBTASK 72-41-00-440-139 Lubricate the Variable Stator Vane Mechanism

    1. Refer to Figure, Figure, Figure and Figure.

    2. Rotate the VSV crankshaft to the low speed stop using a suitable wrench.

      3. Apply CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R) to each variable stator vane lever spindle at location A for the VIGV stage thru to stage 6. Refer to Figure to illustrate the typical area.

      1. WARNING

        YOU MUST USE THE CORRECT PERSONNEL PROTECTION EQUIPMENT WHEN HANDLING AND APPLYING THE LUBRICANT, CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R).

        CAUTION

        DO NOT APPLY LUBRICANT TO THE VSV ACTUATOR.

        CAUTION

        DO NOT LUBRICATE THE CRANKSHAFT BEARINGS.

        NOTE

        These bearings are designed to run dry. Lubrication of the bearings shall cause "swelling" of the bearing fabroid material, resulting in tightness of operation.

        Apply the lubricant using an appropriately sized brush or hand pump spray. Not an aerosol.

      4. Apply CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R) to each pin at location B that connects the VSV levers to the unison ring. Refer to Figure to illustrate the typical area.

      1. WARNING

        YOU MUST USE THE CORRECT PERSONNEL PROTECTION EQUIPMENT WHEN HANDLING AND APPLYING THE LUBRICANT, CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R).

        Apply the lubricant using an appropriately sized brush or hand pump spray. Not an aerosol.

      5. Apply CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R) to the exposed areas of all unison ring centralizing pads, location G on the compressor cases. Refer to Figure.

      1. WARNING

        YOU MUST USE THE CORRECT PERSONNEL PROTECTION EQUIPMENT WHEN HANDLING AND APPLYING THE LUBRICANT, CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R).

        Apply the lubricant using an appropriately sized brush or hand pump spray. Not an aerosol.
