The reservoir is made of two molded light alloy sections which are welded together to make a cylindrical shape. The top of the reservoir has a manifold for the components of the air pressurization system (Ref. 29-14-00). The bottom of the reservoir has two ports for the hydraulic connections. The ports are for the suction and return line connections. A drain valve is installed in the return port. The reservoir also has flanges to attach the quantity indicator/transmitter and the low level switch (Ref. 29-31-00).
The inside of the reservoir includes baffles which give a supply (for 20 s) of fluid under negative 'g' conditions. The baffles also form an anti-emulsion device which limits the emulsion of the fluid when there is a large return flow.
The hydraulic fluid capacities of the reservoir are:
-
the normal fill level 12 l (3.8 USgal),
-
the maximum gageable level 18 l (4.77 USgal),
-
the low-level warning level 3.0 +0.4 -0.4 l (0.8 +0.1 -0.1 USgal).
The reservoir is pressurized to 50 psi (3.5 bar) and is sealed to hold the pressure if there is no supply of air (for example, when the aircraft is parked). It is possible to pressurize the reservoir from a ground supply (Ref. 29-14-00).
The reservoir is filled with hydraulic fluid through the reservoir filling system (Ref. 29-16-00).

B. Engine Pump Fire-Valve 3046GD The engine pump fire-valve is installed in the RH wing between the rear spar and rear false spar, inboard of the pylon. It is in the suction line between the reservoir and the EDP. When the valve closes, it stops the supply of fluid to the EDP.
The engine pump fire-valve 3046GD is the same as the fire valve 1046GK installed in the Green hydraulic system (Ref. 29-11-00).
C. Engine Pump 3030GD The engine pump 3030GD is installed on the accessory gearbox of the RH (No. 2) engine. It is the same as the engine pump 1030GK installed in the Green hydraulic system (Ref. 29-11-00).

D. Manifolds
There are four manifolds in the system. They are:
-
the HP manifold,
-
the PTU manifold,
-
the brake manifold,
-
the LP manifold.
All of the manifolds are aluminum castings. They are machined to make it possible to install different components on them. Some of the hydraulic connections between the manifolds and components are of the bobbin type (Ref. 29-00-00). Thus, replacement of components is possible with minimum effect on other components or pipes. The manifolds are drilled to make the internal connections between components.
The following are the components installed on their related manifolds:
