Ⅲ. Adjustment to clearance of steering gear
1. Maintain wheel at straight line traveling position;
2. Turn steering wheel to both sides;
3. If heard noise of steering gear, adjust the bolt as shown in the diagram until no impinge noise is
heard when turning steering wheel;
4. Tighten up the bolt for another 1 / 8 circle ( about 45°);
5. Road test;
6. If the steering mechanism can not return to the central position by itself, then loosen the bolt for
15°;
7. Road test.
Ⅳ. Adjustment to 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.
4. When in service, 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 service, immediately stop the vehicle,
dismantle and repair accordingly.
