Power steering system adopts driv 鄄
er's physical power and engine
power as steering energy. It can be
steering solely driven by driver if the
boost device do not work. So com
鄄
pared with common mechanical
steering system, power-steering sys
鄄
tem is acuter and safer, easing fa 鄄
tigue of driver to a large extent.
Checking procedures of power -steer 鄄
ing system's working state:
1. Put front wheel on the steering
platform.
2. Turn the steering wheel to left and
right pole to check if the steering
wheel has phenomenon of getting
stuck and getting impeded.
3. Check free play of steering wheel
when engine runs in idle speed. Free
play of steering wheel is 15-35mm.
Rotate adjusting screw clockwise to
decrease the free play, while rotate
anti-clockwise to increase it.
4. Rotational force of steering wheel
is around 19.6N when engine runs in
idle speed.
5. Check working condition of all of
the switches including starter switch,
rain wiper switch, exhaust brake
switch, horn switch and combination
switch.
Procedures of air exhausting in power
steering system:
1. Add steering oil (specified oil ) in 鄄
to oil tank.
2. After standing up the front axle by
using jack, use prop stand to sup
鄄
port frame.
3. Rotate steering wheel to left and
right pole for several times.
4. Check oil level of power-steering
oil tank, add steering oil if there is
not enough oil. Check whether oil lev
鄄
el is in normal temperature scope.
5. Start engine, rotate steering wheel
to left and right pole for several times
if engine runs in idle speed. During
the process of exhausting air, add
steering oil constantly into oil tank to
ensure power-steering oil tank full.
6. Rotate steering wheel to make
wheel confront forward.
7. After switching off engine, check
oil level and add steering oil if neces
鄄
sary.
