B. Test Preparation CAUTION : USE A SECOND WRENCH TO APPLY COUNTERTORQUE TO THE UNION WHEN
_______ YOU DISCONNECT/CONNECT HYDRAULIC LINES ON UNIONS. IF YOU USE THE SECOND WRENCH, YOU WILL NOT LOOSEN OR TIGHTEN THE UNION TOO MUCH.
(1)
Disconnect the air supply line (20) from the reservoir pressurization unit (21).
(2)
Install a blanking cap on the open port at the reservoir
pressurization unit (21).
(3)
Put the open end of the air supply line (20) in a container.
(4)
Fill the container with water so that the end of the air supply line
(20)
is under water. Subtask 29-14-00-280-050
