4. Procedure
_________ (Ref. Fig. 201/TASK 29-00-00-991-013) Subtask 29-00-00-870-064
A. Bleeding Procedure of the Blue Hydraulic System Upstream of the Blue E-Pump
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)
Put a container under the Blue E-pump.
(2)
Disconnect the case drain line (2) of the Blue E-pump from the housing (1) of the case drain filter (2084GM).
(3)
Install a blanking plug (4) in the open port of the housing (1).
(4)
Connect the adapter hose (3) to the case drain line (2).
(5)
Put the end of the adapter hose (3) in the container.
(6)
Make sure that the fluid level in the Blue reservoir is correct. Add fluid as necessary (Ref. TASK 12-12-29-611-001) or (Ref. TASK 12-12-29-611-002).
(7)
Slowly pressurize the Blue hydraulic reservoir so that the air or the mixture of hydraulic fluid and air comes out from the adapter hose
(3) and into the container (Ref. TASK 29-14-00-614-002).
(8)
Depressurize the Blue hydraulic reservoir when the hydraulic fluid flows freely without air (Ref. TASK 29-14-00-614-001).
(9)
Disconnect the adapter hose (3) from the case drain line (2).
(10)
Remove the blanking plug (4) from the housing (1).
(11)
Make sure that the hydraulic line end-fittings are serviceable.
(12)
Connect the case drain line (2) to the housing (1).
(13)
TORQUE the nut of the case drain line (2) to between 2.9 and 3.2 m.daN (21.38 and 23.59 lbf.ft).

(14)
Keep the reservoir depressurization valve (2087GM) open and fill the reservoir to 7.0 l (1.8491 USgal).
(15)
Pressurize the reservoir of the Blue hydraulic system (Ref. TASK 29-14-00-614-002).
