SR-12Steering System
Power Steering (Introduction)
Suggestion on maintenance
The failure of power steering system usually relates to the
steering difficulty due to lack of supplementary force. In such
case, it is the first to verify the problem is produced by the pump
or steering gear when repairing. In doing so, the problem can be
checked on vehicle with the pressure meter.
On-vehicle Inspection
As the power steering is a hydraulic pressure device, its
trouble usually caused by the lack of specified hydraulic
pressure or the abnormal work of control valve. As a result, it
cannot acquire the moderate hydraulic pressure.
In case the problem is caused by the pump, the steering
wheel will deflect toward right or left. On the other side, if the
problem is caused by control valve, when the steering wheel
rotates to left or right, the steering will become more difficult
due to the unequal supplementary force. However, when there
is wear on the piston sealing ring of power cylinder, it also cause
the hydraulic pressure loss that may lead into steering difficulty
toward right or left.
Before making inspection on vehicle, verify the power
steering system firstly to see whether there is air. If any, the air
volume will increase with the variation of hydraulic pressure,
which will cause the hydraulic pressure fluctuation that makes
the power steering work abnormally. In order to verify whether
there is any air in the system, check whether the liquid level
varies or not when the steering wheel rotates completely toward
the right or left. For instance, if there is air in the system, the air
will be compressed, which will reduce the liquid level
remarkably, when the steering wheel rotating. If there is no air
in system, the liquid level variation is very small even though
the hydraulic pressure increases. This is because the liquid
volume will not varies when being compressed. And the small
liquid level variation is caused by the expansion of hose
between the pump and steering gear when the hydraulic pres-
sure increasing.
Meanwhile, the air in system sometimes will cause the
pump or steering gear produce noise when the steering wheel
rotating completely toward a certain direction. After checking
or exchanging the pump or steering gear, the on-vehicle inspec-
tion should be often conducted to guarantee the normal work of
power steering system.

Inspection on tension of driver conveyor
Measure the tension of drive conveyor.
Drive conveyor tension: under the condition of 98 N.
New conveyor: (5-7)mm
Old conveyor:
(7-9)mm
Remark:
ìnew conveyorî means the conveyor that is used on the
machine less than five minutes;
ìold conveyorî means the conveyor that is used on machine
more than five minutes
Check for height of liquid level
1. Keep the body in horizontal status
2. Increase the liquid temperature
When the engine runs idly by 1000 r/m or less, rotate the
steering wheel several times from the locking position to the
reverse locking position to increase the liquid temperature.
3. Check to see whether there is foam or emulsification;
Remark: the foam or emulsification shows there is air in the
system or the liquid level is over-low.
4. Check the liquid level height in oil cup;
Check the liquid level height and, if needed, add the oil.

Change of power steering liquid
1. Tear down the oil-returning hose from the oil cup to
drain the liquid into the container;
2. Run the engine in the idle status, and rotate the
steering wheel toward the max rotating angle for
several times in right or left direction while draining the
liquid, until the oil in steering liquid is drained up.
3. Turn off the engine.
4. Connect the oil-returning pipe and inject the new
power steering liquid in the liquid tank;
Hydraulic oil type: No.8 Liquid drive oil (Q/SH003.01.012-88)
5. Start the engine, and make it running in the idle status.
Rotate the steering wheel to the max rotating angle repeatedly
several times, meanwhile, supplement new power steering
liquid in the liquid tank until there is no foam or turbidities in
the liquid tank, and the oil indicating lamp reaches the marked
range when the engine is turned off.
6. Tighten the liquid tank cover
7. Exhaust the air in the power steering system;
Ai-r bleeding in power steering system
1. Check the liquid level height in the liquid tank
Check the liquid level and, if needed, supplement the liquid.
2. Start the engine in the idle status and rotate the
steering wheel repeatedly to the max rotating angle
several times.
3. Turn off the engine and connect the ethane pipe and
bleeding plug.
4. Start the engine and rotate the steering wheel
repeatedly to the max rotating angle several times.
5. Locate the steering wheel at the intermediate position.

Remark
(a) Where the bolts of recirculating ball are connected with
the arm or lever, the lubricant on its surface should be
cleaned.
(b) Screw up the bolts and nuts of re-circulating ball to the
specified torque, and then screw the nut forward to the
degree that the split pin can be encased in.
(c) Check the Alignment of Front Wheel and side slip after
any part of steering linkage is mounted.

Common Troubleshooting
a. Such failures as inaccuracy indication, out-operation of indicator, on the fly of large and small summation meters
(mechanical wheel drive excluded) or incomplete liquid crystal display are caused by the interior failures of the
instrument, therefore, these failures, once occur, should be judged according to the instrument interior failures, and
change the combination instrument directly.
b. In case both the large and small summation meter and the indicator of electronic odometer are on the fly, such failures
can be removed by disassembling the speed sensor from the whole vehicle first, then connecting the sensor and
combination instruments as shown in the drawing.
Then, open the power supply and run the rotors quickly to observe the indicator variation of odometer.
the odometer indicator
should be no less than 40Km/
h variation in speed under
common condition whenrunning the rotors,
otherwise,
