B. Installation of the Hand Pump

CAUTION: USE A SECOND WRENCH TO APPLY COUNTERTORQUE TO THE UNION WHEN YOU DISCONNECT/CONNECT HYDRAULIC LINES ON UNIONS. IF YOU DO NOT USE THE SECOND WRENCH, THERE IS A RISK THAT YOU WILL LOOSEN OR TIGHTEN THE UNION TOO MUCH.

CAUTION: YOU MUST INSTALL HYDRAULIC TUBES WITH HYDRAULIC FLUID AS LUBRICANT.

(1) Clean the component interfaces and the adjacent area.
(2) Do an inspection of the component interfaces and the adjacent area.

NOTE: Make sure that the groove in the adapter for the hand pump handle, is in the neutral position.

(3) Put the hand pump (3) in position in the ground service panel (6).
(4) Install the bolts (20) and the washers (19) to attach the hand pump (3) to the bracket (18). Do not tighten the bolts (20) at this time.
(5) Put the bracket (17) in position on the ground service panel (6).
(6) Install the screws (4) and the washers (5). Fully tighten the screws (4).
(7) Install the bolts (15) with the washers (16). Fully tighten the bolts (15) and (20).
(8) Make sure that the hydraulic line end-fittings are serviceable.
(9) Apply Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) to the thread of the union nut (7).
(10) Attach the union nut (7) to the adapter (8).
(11) TORQUE the union nut (7) to between 1.7 and 1.5 m.daN (12.54 and 11.06 lbf.ft )

E. Test of the Hand Pump
(1) Remove the blanking cap from the reservoir fill valve 1698GM.
(2) Connect the flexible hose 1699GM to the fill valve 1698GM.
(3) Put the end of the flexible hose into a container of Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
(4) Make sure that the manual selector valve 1134GM is set to NEUTRAL.
(5) Put the hand pump lever (located on the ground service panel of the Yellow hydraulic system) on the hand pump 1009GM.
(6) Operate the hand pump through 3 or 4 cycles to pressurize the manual selector valve 1134GQ.

NOTE: A pressure relief valve in the fill selector valve operates if too much pressure is put into the system. If this happens, a small amount of fluid will go into the reservoir of the Yellow hydraulic system.

(7) Set the selector switch on the manual selector valve 1134GQ to BLUE. The blue indicator light comes on.
(8) Operate the hand pump between 5 and 10 strokes. The needle of the reservoir quantity indicator shows the contents of the reservoir of the Blue hydraulic system.

NOTE: When you operate the hand pump between 5 and 10 strokes, a small quantity of fluid (between 200 ccs and 400 ccs) goes into the selected reservoir.

(9) Make sure that there are no leaks from the pipe connections at the outlet port (mark A on the port).
(10) Set the selector switch of the manual selector valve 1134GQ to NEUTRAL. The Blue indicator light goes off and the needle of the reservoir quantity indicator does not show the reservoir contents.
(11) Disconnect the flexible hose from the fill valve 1698GM.
(12) Put the flexible hose in its position in the ground service panel of the Green hydraulic system.
(13) Install the blanking cap on the fill valve 1698GM.
(14) Remove the hand pump lever from the hand pump 1009GM.
(15) Put the hand pump lever in position on the ground service panel of the Yellow hydraulic system.
