Procedure

    1. SUBTASK 72-41-00-440-142 Install the HP Front Split Cases

    1. Refer to Figure.

    2. NOTE

      The retaining clamp plate assembly will need to be released and moved clear of the jacking screws if the axial settings need to be adjusted.

      Loosen the locknut on the heel pin (detail 15). Release the hand knob (detail 22) and move the retaining clamp plate assembly clear of the three jacking screws (detail 12).

    3. If necessary loosen the locknut on the tie-rod adapter (installed through the center of the HP module), refer to Figure by approximately 0.40in. (10 mm) to allow axial movement of the static and rotating parts.

      4. Position the six dial test indicators or equivalent instrumentation measuring devices as follows.

      1. NOTE

        This instrumentation will monitor the relative movement of the HP static components and the stand.

        Put three dial test indicators, equally spaced, on the surface of the stand top plate (detail 3) so each dial indicator button contacts each of the three support plates (detail 4).

      2. Put three dial test indicators, spaced equally, on the IAE 1P16046 Removal/Installation fixture or IAE 1P16543 Removal/Installation fixture tooling structure so each dial indicator button contacts the rear surface of the Stage 2 retaining plate slot on the Stage 2 Turbine Hub ENGINE-STAGE 2 TURBINE HUB (72-45-31,01-011).

        NOTE

        This instrumentation will monitor the true relative movement of the HP rotating components and the static components. This is the critical dimension to be monitored.

      5. Confirm the true axial displacement of the HP module cases and stage 2 HP turbine and the IAE 1R19463 Stand - Surgical strike 1 off.

      1. Refer to the record of the readings taken at the six positions with the front half casings removed, refer to TASK 72-41-00-040-001-D00.

      2. Take the readings on the three dial test indicators in contact with each of the three support plates (detail 4). These readings should be the same as the final readings taken during TASK 72-41-00-040-001-D00.

      3. NOTE

        This is to make sure that the relative reverse movement during installation is the same as that recorded during the removal of the cases.

        Take the readings on the three dial test indicators in contact with the rear surface of the stage 2 retaining plate slot on the stage 2 turbine hub ENGINE-STAGE 2 TURBINE HUB (72-45-31,01-011). These readings should be the same as the final readings taken during TASK 72-41-00-040-001-D00. These readings should be within 0.020 in. (0.5 mm) of the readings taken at the three support plates.

      6. Install the HP compressor front split half casings as given in Step at the same time as the procedure in this SUBTASK.

      1. CAUTION

        THESE READINGS ARE THE MAXIMUM PERMITTED TOTAL MOVEMENT TO RETURN TO THE DATUM POSITION. YOU MUST NOT EXCEED THESE READINGS OR DAMAGE TO ENGINE COMPONENTS WILL OCCUR.

        Make sure the dial test indicator readings agree with the final readings taken in TASK 72-41-00-040-001-D00.

      2. CAUTION

        DURING THE REMOVAL AND INSTALLATION OF THE HP COMPRESSOR FRONT HALF CASES TAKE CARE NOT TO DAMAGE THE HP COMPRESSOR ROTOR BLADES. DO NOT USE EXCESSIVE OR MORE FORCE THAN IS NECESSARY.

        Support the split casings on detail 10 half rings. Move the cases carefully into position on detail 10 and then install and fully locate the split casings around the HP compressor assembly . Make sure that the casings do not touch and damage the HP compressor rotor blades.

      3. CAUTION

        THERE MUST NOT BE A DIFFERENCE OF MORE THAN 0.020 IN. (0.5 MM) BETWEEN THE READINGS OF EACH OF THE DIAL TEST INDICATORS. IF THE DIFFERENCE IS MORE THAN THIS LIMIT THEN DAMAGE MAY OCCUR TO HP MODULE COMPONENTS.

        CAUTION

        YOU MUST MAKE A RECORD OF THE DIAL TEST INDICATOR READINGS AFTER EACH INCREMENTAL MOVEMENT MADE.

        Refer to the readings taken in TASK 72-41-00-040-001-D00. During installation use the readings in a series of incremental steps to reverse and match those taken during the Disassembly procedure.

      4. Adjust the three jacking screws (detail 12) to make adjustments to the axial movement of the static components relative to the rotating components. Turn the jacking screws in an anti-clockwise direction to move the HP compressor rear cases forward (the rear cases move in a direction towards the base of the build stand). Make each adjustment so each of the dial test indicator readings are no more than 0.020 in. (0.5 mm) for each increment adjustment.

      5. Make sure that readings do not differ by more than 0.020 in. (0.5 mm) between dial test indicators. This is to make sure that the axial movement is adjusted evenly and equally and is the same as that recorded during Disassembly.

      6. The readings at stage 2 HP turbine position is the critical dimension to be monitored and represents the true axial movement between the static and rotating assemblies. The final reading must agree with that taken during Disassembly to make sure that the original axial displacement is correctly restored.

      7. Remove the instrumentation.

      8. Move the retaining clamp plate assembly into position to make contact with the three jacking screws (detail 12). Adjust and tighten the locknut on the heel pin (detail 15) but do not fully torque the lock nut. Tighten the hand knob (detail 22) to hold the assembly firmly.

      9. Tighten the locknut on the tie-rod adapter (installed through the center of the HP module) to prevent the axial movement of the static and rotating parts.

    2. SBE 72-0400: HP compressor variable vanes - inlet guide vane and stages 3 to 5 with optimised build and setting instructions.

    3. This check must be done after each time the connectors are installed to the VSV actuating ring assemblies.

      4. This is the general procedure to make sure that the left and right hand connectors which are installed to the upper and lower actuating rings are installed correctly. The check will make sure that the dowels which hold the connectors to the actuating ring are installed correctly and are not mis-seated. The following gives the causes of an incorrectly installed assembly and what to look for :-.

      1. It is not easy to decide if the connectors for a particular stage is installed incorrectly. An incorrect installation can occur if a dowel is not installed correctly in a mating hole of an actuating ring and instead touches the mating face of the actuating ring.

        The wall of the actuating ring can become clamped between the dowel and the internal actuating ring boss, when this occurs the bridge piece is not held. The head of the mis-seated dowel can be visible above the connector and/or the connector could be offset from the actuating ring.

        No indication of misaligned connectors is evident when the bolt(s) are torque tightened because of a 'cross-keying' action of the dowels in the connectors.

      5. Inspect the left hand and right hand actuating ring and connector joint for each stage.

      1. Check the clearance between the connector and the actuating ring, it should be possible to put a 0.001 in. or 0.002 in. (0.025 mm. or 0.05 mm) feeler gauge in the clearance. If this is not possible do Step.

      2. For the left hand and/or right hand joint (as applicable) examine the dowel heads, use a torch if necessary. Make a comparison in the position of each dowel. Look for differences in radial distances between the connector and the upper and lower actuating ring, all the distances should be the same. If there is a distance which does not appear regular then do Step to Step.

      3. Remove the connector and look for new marks on the actuating ring adjacent to the dowel mating hole caused by a mis-aligned dowel.

      4. Install the connector and make sure the dowels are correctly seated before you torque tighten the bolts.
