TRUCK IS HARD TO STEER. (Cont) -726250847

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 pressure to zero.

Damage to main steering pump or hydraulic pump control will occur if load valve is closed for more than 10 seconds.

FLOW/PRESSURE TEST

(1)

Disconnect hose 2301 from front

steering gear.

(2) Install a flowmeter in line between

hose 2301 and rear steering gear.

(3) Fully open flowmeter load valve.

(4) Start engine (TM 9-2320-364-10).

(a) If less than 6 gpm (23 lpm) are

present, replace priority flow

valve (Para 12-13).

(b) If 6 gpm (23 lpm) are present,

priority flow valve is OK.

(5) Slowly close load valve on meter.

(a) If 2000 to 2025 psi

(13,790 to 13,962 kPa) are not

present when flow drops

to 0 gpm (0 lpm), adjust

pressure sensing valve

(Para 12-2).

(b) If 2000 to 2025 psi

(13,790 to 13,962 kPa) are

present, pressure sensing valve

is adjusted correctly.

(6) Open load valve fully.

(7) Turn OFF ENGINE switch.

(8) Install pressure sensing valve

cover.

(9) Connect hose 2301 to front

steering gear.

(10) Check steering oil level and add oil

as necessary (TM 9-2320-364-20).

(11) Close front access cover.
