 TM 9-2320-364-34-1
The LHS hydraulic system operates at
S
oil 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
S
cause falls. To avoid injury, wipe
up spilled fuel or oil with rags.
Do not allow valve to go over relief for
over 10 seconds, or damage to equipment
may result.
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) With the aid of an assistant, observe
pressure gage while holding joystick
in LOAD position.
(a) If pressure is not 3600 to 3625 psi
(24,822 to 24,994 kPa), perform
Steps (5) and (6) below and go to
Step 8 of this Fault.
(b) If pressure is 3600 to 3625 psi
(24,822 to 24,994 kPa), relief
valve is OK, perform Steps (5)
through (7) below and go to
Step 10 of this Fault.
(5) Set hydraulic selector switch to OFF
position.
(6) Turn OFF ENGINE switch.
(7) Disconnect pressure gage from
multifunction manifold.
