       3. Attach the plate to the No. 5 Bearing outer oil feed with two bolts. Torque the bolts to 85 lbfin to 105 lbfin (9.60 Nm to 11.86 Nm).

32. SUBTASK 72-00-50-420-221 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. Attach the cart vacuum gage hose to the plug of the vacuum test adapter.

       NOTE

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

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

       Ambient Pressure of the Day (psia)	Vacuum Pressure (psia)
       14.7	4.9
       14.5	4.7
       14.3	4.5
       14.1	4.3
       13.9	4.1
       13.7	3.9
       13.5	3.7
       13.3	3.5
       13.1	3.3

       Vacuum pressure (psia) = Ambient pressure of the day (psia) - 9.8 psia

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

    6. Record 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.

33. SUBTASK 72-00-50-420-222 Remove the Vacuum Test Cart, the Adapter and the Plate

    1. Disconnect the hose of the vacuum test cart from the adapter. Refer to Figure.

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

34. SUBTASK 72-00-50-420-223 Install the Module Dressings

    1. Install the module dressings. Refer to TASK 72-00-50-420-005-B00 (INSTALLATION-007).
