TM 9-2320-364-34-1
The LHS hydraulic system operates at oil
S
pressures up to 3675 psi (25,339 kPa).
Never disconnect any hydraulic line or
fitting without first dropping pressure
to zero. Failure to comply may result in
serious injury or death to personnel.
Fuel and oil are slippery and can cause
S
falls. To avoid injury, wipe up spilled
fuel or oil with rags.
PRESSURE TEST
(1) Connect 0 to 6000 psi (0 to 41,370 kPa)
pressure gage to multifunction
manifold, port G2.
(2) Start engine (TM 9-2320-364-10).
(3) Set hydraulic selector switch to
AUTO position.
(4) Adjust LHS relief valve while
observing pressure gage connected
to port G2.
(a) If pressure cannot be adjusted
up to 3600 to 3625 psi
(24,822 to 24,994 kPa) using LHS
relief valve, perform Steps (5)
through (7) below and replace
LHS relief valve (Para 17-8).
(b) If pressure can be adjusted up
using LHS relief valve, fault not
corrected. Perform Steps (5)
through (9) below and notify
supervisor.
(5) Set hydraulic selector switch to OFF
position.
(6) Turn OFF ENGINE switch.
(7) Disconnect pressure gage from
