4.19 Remove the two lower fixing nuts from the steering column

with 13# socket.

Torque: 25±3 Nm

4.20 Remove the connecting nuts of steering column and steering

universal joint with 10# socket to remove the steering column

assembly.

Torque: 25±3 Nm

4.21 Remove the connecting bolts of steering universal joint and

steering gear with hand.

Take out steering universal joint assembly.

5. Installation Procedure

Refer to removal procedures.

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.

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.
