T-45A UJPT, E2-C2, ADV, & IUT Eng-09
Hydraulic System
(3) Provides fluid pressure to compo-
nent seals during nonoperating
periods to minimize leaks
b.
Physical
(1) Similar to HYD 1 reservoir, except
smaller, less load, less capacity.
Consists of a cylinder with a free-
floating piston that separates
hydraulic fluid from nitrogen
(2) Pressurized with nitrogen to
proper pressure during ground
maintenance
(3) Fluid quantity depends both on
quantity remaining in the accumu-
lators and the hydraulic fluid
temperature
2.
Engine-driven pump (EDP)
Overlay 2
HYD 2 EDP
a.
Location: forward left side of engine
accessory gearbox
b.
Description
(1) Produces hydraulic pressure for
HYD 2 system
(2) Output volume varies in response
to demand
c.
Physical
(1) Mounted on and driven by engine
accessory gearbox
(2) Variable displacement pump
(3) Constant output pressure: 3,000
psi at 6 gpm flow due to smaller
load
