    4. Subtract dimension B from dimension C and the result will be the required No. 4 bearing spacer dimension.

       1. Usually, the necessary spacer will be a class 11 or 12. After you subtract dimension B from dimension C, if a different class is necessary, check the measurements and do the calculation again.

          1. Use the guidelines for correct bearing tolerances that follow so you can meet the final assembly check:

             If the C - B calculation results in a class 9 or 10 spacer - Install a class 11 spacer.

             If the C - B calculation results in a class spacer that is less than 9 - Install a class 10 spacer.

             If the C - B calculation results in a class 13 or 14 spacer - Install a class 12 spacer.

             If the C - B calculation results in a class spacer that is more than 14 - Install a class 13 spacer.

        7. Move the clamp assemblies in the counterclockwise direction (direction of arrows) and tighten the wingnuts.

        8. Install the IAE 1P16011 Wrench 1 off through the adapter to engage the retaining nut splines.

        9. NOTE

           You can use IAE 1F10016 Mechanical wrench as an alternative to IAE 1F10015 Hydraulic wrench.

           Attach a hoist to the IAE 1F10015 Hydraulic wrench 1 off and install over the wrench, Figure.

        10. Engage the anti-rotation pins on the wrench with the holes in the adapter. Tighten the hexagon head bolts to attach the wrench to the adapter.

    20. Torque the bearing retaining nuts with the hydraulic wrench.

        1. Turn the retaining nut an angle of turn of 80 degrees plus or minus two degrees.

    21. Remove the bearing retaining nut tools.

        1. Loosen the hexagon head bolts and remove the hydraulic wrench from the adapter.

        2. Remove the wrench from the nut.

        3. Loosen all the wingnuts on the clamp assemblies.

        4. Move the clamp assemblies in the clockwise direction (opposite direction of the arrows).

        5. Pull the clamps assemblies out and tighten the wingnuts, touches the hub.

        6. Remove the adapter from the stage 2 turbine hub.

    22. Install the No. 4 bearing lock ENGINE-ATTACH PARTS & FITTINGS-HP SYSTEM (72-40-00, 04-060).

        1. 

           CAUTION

           THE NO. 4 BEARING LOCK CAN BE INSTALLED IN THREE DIFFERENT POSITIONS WHEN YOU LOOK FROM THE REAR OF THE ENGINE. IF THE LOCK IS NOT INSTALLED IN THE CORRECT POSITION, THE BEARING RETAINING NUT CAN BECOME LOOSE.

           NOTE

           This position will keep the bearing retaining nut at the correct torque.

           Position and install the clockwise side of the rear lock tabs nearest to the counterclockwise side of the tabs on the bearing and install the lock.

    23. Install the retaining ring ENGINE-ATTACH PARTS & FITTINGS-HP SYSTEM (72-40-00, 04-040) to attach the lock in position.

    24. Remove the protective cover.

    25. NOTE

        The tool bolts and nuts must be removed as the engine bolts and nuts are installed.

        Install all the bolts and nuts and the brackets to the HP Turbine Case front flange.

    26. Torque the nuts to 180 lbfin to 200 lbfin (20.337 Nm to 22.597 Nm).

24. SUBTASK 72-00-45-220-218 Examine the HPC Rear Shaft for Surface Damage

    1. Refer to Figure.

    2. Examine the rear shaft inner bore at the inspection area given in the figure.

       1. Surface damage not more than 0.003 in. (0.08 mm) in depth

          1. Accept

       2. Other than (1)

          1. Reject

25. SUBTASK 72-00-45-220-204 Check the HP Turbine Assembly Running Distance

    1. Install the IAE 1P17515 Gage 1 off on the rear flange of the HP turbine rotor and stator assembly.

       1. Before the gage is used, move the digital indicator to the machined area on the gage and set the digital indicator to zero. The dimension of the indicator rod when the digital indicator is zero is 1.194 in. (30.328 mm).

       2. Install the gage to the rear flange of the turbine case and the digital indicator rod on the Stage 2 Turbine Hub lug end.

       3. Measure the distance to the lugs on the Stage 2 Turbine Hub at three equally spaced positions.

          1. At each measurement, add or substract the digital indicator reading to the 1.194 in. (30.328 mm) dimension.

          2. Average the three measurements.

          3. The running distance must be 1.194 in to 1.214 in. (30.33 mm to 30.84 mm).

    2. Remove the gage.

    3. Install the IAE 1P16060 Protective cover 1 off or the IAE 1P17758 Protective cover 1 off to the rear flange of the HP Turbine Rotor And Stator Assembly. Put equal hand pressure on the outer edge of the cover to hold in position.

26. SUBTASK 72-00-45-220-222 Examine the Stage 2 Turbine Hub for Damage

    1. Examine the Stage 2 Turbine Hub for dents, nicks and scratches that occured during the assembly process.

       1. Dents, nicks and scratches

          1. Diassemble. Refer to TASK 72-00-45-020-001-B02; then Repair, VRS3238 TASK 72-45-31-300-001 (REPAIR-001)
