Procedure

    1. SUBTASK 72-00-50-420-385 Install the Vacuum Test Adapter and the Blank-off Plate to the Turbine Exhaust Case

      1. Install the IAE 1P16354 Vacuum Test Adapter 1 off to the No. 5 bearing outer oil scavenge tube. Figure.

      1. Make sure that the adapter has no damage.

      2. Lubricate the bolts, nuts and washers with CoMat 10-077 APPROVED ENGINE OILS.

      3. Attach the adapter to the No. 5 bearing outer oil scavege tube and safety with four bolts. Torque the bolt to 85 to 105 lbsfin (9.604 to 11.863 Nm).

      2. Install the IAE 1P17523 Blank-off Plate 1 off to the No. 5 bearing outer oil feed tube. Figure.

      1. Make sure that the plate has no damage.

      2. Lubricate the bolts, nuts and washers with CoMat 10-077 APPROVED ENGINE OILS.

      3. Attach the plate to the No. 5 bearing outer oil feed tube and safety with three bolts. Torque the bolt to 85 to 105 lbsfin (9.604 to 11.863 Nm).

    2. SUBTASK 72-00-50-720-052 Do an Evacuation Check for the No. 5 Bearing Compartment

    1. Refer to Figure.

    2. Connect the hose of the IAE 6F10030 Vacuum test cart 1 off to the nipple of the IAE 1P16354 Vacuum Test Adapter 1 off.

    3. NOTE

      Refer to the manufacturer's manual for the operation of the vacuum test cart.

      Attach the cart vacuum gage hose to the plug of the IAE 1P16354 Vacuum Test Adapter.

    4. Set the air pressure at the test port to -20in Hg (-508 mm Hg gage). Based on the ambient pressure, refer to the table below for the vacuum pressure in psia.

    5. Read the airflow indicated by the rotor meters on the vacuum cart.

    6. Make a record of the indicated airflow.

    7. If the indication is more than 10 PPH (4.54 kg per hour), reject the module.

    8. Stop the vacuum pump.

    3. SUBTASK 72-00-50-420-386 Remove the Vacuum Test Cart, Adapter and Plate.

    1. Disconnect the hoses of the vacuum test cart from the adapter. Figure,

    2. Remove the plate and the adapter. Figure and Figure.
