(7) Install the screws (21) and the washers (22).
(8) Connect the pipe to the adapter (8) installed in port B of the valve assembly (17).
(9) TORQUE the union nut (9) to between 1.7 and 1.5 m.daN (12.54 and 11.06 lbf.ft )

.
(10) Connect the pipe to the adapter (11) installed in port A of the valve assembly (17).
(11) TORQUE the union nut (10) to between 1.7 and 1.5 m.daN (12.54 and 11.06 lbf.ft )

.
(12) Connect the pipe to the adapter (19) installed in port G of the valve assembly (17).

E. Do this Test

ACTION	RESULT
1.On the ground service panel of the Green hydraulic system: operate the hand pump through 3 or 4 cycles to pressurize the manual selector valve.	On the ground service panel of the Green hydraulic system: there are no leaks from the manual selector valve or from the pipe connection at the port marked A of the manual selector valve. NOTE: A pressure relief valve in the fill selector valve will operate 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.
2.On the manual selector valve 1134GQ: set the selector switch to BLUE.	On the reservoir quantity indicator 1834GQ: the blue indicator light comes on.
3.On the hand pump 1009GM: operate the hand pump between 5 and 10 strokes.	On the reservoir quantity indicator 1834GQ: the needle of the reservoir quantity indicator shows the contents of the Blue reservoir. there are no leaks from the pipe connection at the port marked B of the manual selector valve. NOTE: When the hand pump is operated between 5 and 10 strokes, a small quantity of fluid (between 200 and 400 ml) will go into the selected reservoir.
4.Do the steps 2 and 3 again for the Yellow system.	The same result as in the steps 2 and 3, for the Yellow reservoir.
5.Do the steps 2 and 3 again for the Green system.	The same result as in the steps 2 and 3, for the Green reservoir.
6.On the manual selector valve 1134GQ: set the selector switch of the manual selector valve to NEUTRAL.	On the reservoir quantity indicator 1834GQ: the Green indicator light goes off. the needle of the reservoir quantity indicator does not show the reservoir contents.
