Tire Inflation; Installation Of Wheel And Tire Assembly; Tightening Method Of Wheel Bolts; Installation Of Decorative Cover - Chery A113 Maintenance Manual

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 3.0bar,
and the spare wheel assembly shall be stored separately from four
wheels. Before the four-wheel alignment, check the air pressure of
all wheels and adjust the air pressure: 2.3bar for front wheels and
2.1bar for rear wheels.

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 100g·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 Assembly.

When fixing wheel and tire assembly, first, manually screw up the
wheel bolt onto the hub for pretension, after that 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 prevent from wheel damage, over loose or over tight. It is not
allowed to apply grease on wheel bolt (For new installed wheel
and tire assembly, the wheel bolts should be tightened at first
running of 100km to guarantee the tightening torque. The
tightening torque checking of wheel bolts is one of the items of
regular maintenance)
5. Tightening Method of Wheel Nuts
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 Decorative Cover

Mount trim cover or place trim cover as required. When fitting clip-
type trim cover, place knock in position by hand or via rubber tools.
