 TM 9-2320-364-34-1
The truck steering operates with 3000 psi (20,685 kPa) hydraulic pressure. A high pressure hydraulic oil stream
can pierce a body and cause severe injury to personnel. Never disconnect any high pressure hydraulic oil line or
fitting without first dropping pessure to zero.
PURGE STEERING SYSTEM
Perform steering system purging
procedure (Para 12-13).
(1) If there is air present in steering
hydraulic system, continue to purge
system (Para 12-14) and go to Step
13 of this fault.
(2) If there is no air in steering hydraulic
system go to Step 3 of this fault.
NOTE
Leave input shaft and steering shaft
disconnected. They will be reconnected later
in this task.
