III. Adjustment of Steering Gear Clearance
1. Place the wheels at linear driving position;
2. Rotate the steering wheel towards both sides;
3. If heard noise of steering gear, adjust the screw as shown in the diagram until no impinge noise is heard
when turning steering wheel;
4. Tighten the screws for further 1/8 turn (approximate 45°);
5. Carry out the road test;
6. If the steering mechanism can not return to the central position by itself, then loosen the bolt for 15°;
7. Carry out the road test.
IV. Adjustment of Power Steering System
1. Correctly connect power steering oil pipe—where the tightening torque for the connector between oil return
pipe, high-pressure oil pipe and steering gear shall be 35±3N.m, 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 described as below:
Fill power steering hydraulic fluid into steering reservoir assembly 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.
