for tires will be additionally provided in written forms by product division of Chery Company or

suppliers, and indicated on process sheet.

2.5 Carry out tire inflation strictly in accordance with specified pressure. During inflating

process, air pressure shall not exceed 10% of rated pressure. When performing separate

packaging to spare wheel assembly, the rated inflation pressure shall be 3.0 bar, and the spare

wheel assembly shall be stored separately from four wheels. Before the four-wheel alignment

work, check the air pressure of tires of four wheels and regulate the pressure: 2.3 bar for front

wheel, and 2.1bar for rear wheel.

3. Tire Inflation

After completion of tire inflation, screw up the protective cap of valve, and then carry out

dynamic balancing test. Fit appropriate balance weight at the internal and external fringe of

wheel rim as required. It is required that the unbalancedness of the final assembly shall be less

than 100 g·cm, which is approximately equivalent to a 5g balance weight at the internal and

external fringe of wheel rim. Note: each wheel and each side can use only one balance weight.

Additionally, its maximum mass shall not be more than 70g. During assembling process, never

hit the balance weight too heavy. Otherwise, replace balance weight in time. In addition, never

use the replaced balance weight again.

4. Installation of Wheel and Tire Assy

When install wheel and tire assy, firstly, manually screw up the wheel bolt onto the hub for

pretension, then use special tools for tightening in accordance with diagonal process. Tightening

torque shall be 110±10N.m. It is prohibited to use impact wrench to cause wheel damage, over

loose or over tight. It is not allowed to apply grease on wheel bolt. (For the newly-installed

wheel and tire assy, after the initial mileage of 100 km, tighten the wheel bolts once to ensure the

tightening torque. Checking the tightening torque of wheel bolts is one of routine maintenance.)

5. Method to Tighten the Wheel Nut

Tighten the fixing nut in a decussate way, the tightening force shall be approximately equal, then

wheel shall be able to turn freely. When carry out final tightening, the wheel shall be on the

ground.

6. Installation of Trim Cover

Install trim cover or place trim cover as required. When fitting clip- type trim cover, place knock

in position by hand or via rubber tools.

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.
