TASK 72-50-30-440-001 LPT Stage 3 Rotor Assembly - Assemble, Assembly-001

General

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 70-41-01-400-501 and SPM TASK 70-41-02-400-501.

Special torque data and assembly tolerances are included in the procedure.

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 TASK 72-50-00-990-501 for a sectional view of the LP turbine module.

Use new rotor bolts and nuts

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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

NOTE

During assembly, it is not necessary to measure, calculate and record the fits and clearances if:
a) Both parts are new, or
b) Used parts (inspected and/or repaired) are within limits.
Above is valid for any combinations of a) and b), except for "Selected Fit" parts.

    1. Refer to Figure.

    2. Protect the moment weight equipment for environmental effect.

    3. Install the moment weight equipment on a surface plate which is free from vibrations.

    4. Do not change the adjustment of the hydraulic stabilizer at the moment weight equipment.

    5. Make sure that during the moment weight of the blades no tension or load will be applied to the moment weight equipment.

    6. Balance the moment weight equipment with the adjusting screw and the spirit level.

    7. Install the blade distribution system to the moment weight equipment.

    5. SUBTASK 72-50-30-440-052 Weigh the Stage 3 Turbine Blades

    1. Refer to Figure.

    2. Before you weigh the stage 3 turbine blades, examine if a unbalance value is engraved on the stage 3 turbine disk. Refer to Figure. If there is a unbalanced value engraved on the disk, use this value on the disk for technical data to blade distribution in Step.

    3. Turn on the installed blade distribution system.

    4. Use the blade distribution diskette and put it in to the computer.

    5. Make the input for all required technical data to do blade distribution in accordance with the computer manual in to the blade distribution system.

    2. Identify the disk slot with the disk serial number. The serial number is vibrograved on the rear face of the disk. The groove number one is the first groove on the right side of the serial number. Make a mark to the groove number one at the front side. Use CoMat 02-129 MARKER.

    3. NOTE

      Make sure that you use the correct locating ring of the IAE 1M14153 Assy/disassy stand 1 off for the stage 3 disk.

      Put the stage 3 turbine disk on the IAE 1M14153 Assy/disassy stand 1 off, turbine disk front flange upwards.

    4. NOTE

      The turbine blade identification number is the same as the blade identification number at the blade distribution protocol.

      Insert the first stage 3 turbine blade in accordance with the blade distribution protocol in to the groove number one.

    5. Insert the remaining turbine blades in accordance with the blade distribution protocol. Work in counterclockwise direction look to the front side of the disk and insert blades helical in to the grooves.

    6. Lightly hit the blades at the blade roots. Operate stepwise and in counter clockwise direction to engage the blades. Move stepwise the support of the assy/disassy stand upwards. Use the IAE 1M14079 Plastic wedge 1 off and a soft headed mallet.

    7. Repeat Step until all the blades are fully engaged in to the grooves of the disk. Make sure that the hook from each turbine blade root is in contact with the turbine disk front face.

    8. Inspect the gap at the stage 3 turbine blade inner platforms. Use a torch light. If you can not see a gap, use a feeler gage to measure the correct gap (minimum thickness 0.00118 in. (0.03 mm)).

    7. SUBTASK 72-50-30-440-054-A00 V2500-A1 Install the Clamping Ring on to the Stage 3 Turbine Disk

    5. Attach the balancing fixture disk with the 12 screws to the balancing fixture base plate. Tighten the screws.

    6. NOTE

      1. The balancing fixture sleeve is used to safety the LP turbine rotor assembly in radial position. This is achieved when the balancing fixture disk is pushed at the inner diameter against the balancing base plate. The caused deflection of the balancing fixture disk goes to a small diameter reduction at the abutment face to the LPT rotor disk rear snap diameter. Correct adjustment of the set screw, part of the balancing base plate prevents overstressing.

      2. Do not tighten the balancing fixture sleeve bolt at this moment.

      Install the IAE 1M14021 Balancing fixture sleeve 1 off to the balancing fixture disk.
