III. Adjustment of Clearance of Steering System

1. Maintain vehicle wheel at straight line traveling position;
2. Turn the steering wheel towards the both sides;
3. If heard steering gear noise, adjust the bolt position as shown in the figure until no impinging
noise is heard while turning steering wheel;
4. Tighten up the bolt for another 1/8 circle (about 45º);
5. Road test;
6. If the steering mechanism can not return to the central position by itself, then loosen the bolt
for 15º;
7. Road test.

IV. Adjustment of Power Steering System

1. Correctly connect power steering oil pipe, where the tightening torque for the connector of
steering gear with oil return pipe, high-pressure oil pipe should be 35±3N.m, and the tightening
torque of hollow bolt connecting high-pressure oil pipe and power steering pump shall be 45±
3N.m. When filling power steering oil, it is recommended to use special purpose vacuum
pumping oil. The specifications for filling power steering hydraulic fluid and exhaustion are
shown as below:

Fill power steering hydraulic fluid into steering reservoir assy to the maximum level, start

engine at low speed (idle speed) to drive the steering pump, the steering system will be quickly
full of hydraulic fluid. In the oil filling process, only let engine run at idle speed to drive vane
pump. Meanwhile, continuously add hydraulic fluid to prevent vane from sucking air due to oil
level drops.

2. When hydraulic fluid in the oil tank presents emulsification state, or the pump emits excessive
noise (under normal condition, max. noise shall be 80 db), it must carry out exhaustion process.
The exhaustion procedure is described as below:

Jack the front part of the vehicle till two front wheels are hung up, start the engine, turn the

steering wheel to right and left till reach limit position (caution: after come to the limit position,
try not to stop, even if stop, never maintain over 2 seconds). Repeat above action for several
times, until the air in the system is gradually exhausted from the oil reservoir. In this process,
with the drop of oil level, continuously supplement hydraulic fluid until the oil comes to
specified level.

3. Regularly check and adjust the tension of power steering belt: vertically apply a 100N force at
the middle of the belt, the max. deflection of belt shall be less than 5 mm, otherwise adjust the
belt tension until meet the above requirement via adjusting tension bolt.

4. When in operation, it is prohibited to turn the steering wheel to limit position, even if it has to
do so, never maintain at this position over 10 seconds. It is strictly prohibited to use power
steering pump without oil. If the driver suddenly feels the steering heavy in operation,
immediately stop the vehicle to make removal and repair accordingly.
