Chery A15. Manual — part 71

INTRODUCTION OF PERFORMANCE

※The steering force of the steering wheel can be decreased. Power can be felt obviously,

especially when the vehicle turns on spot or turns with great corner at low-speed.

※The steering sensitivity is enhanced.

※The impact of kickback from ground on the steering wheel is reduced.

※In the case of tire burst, the sudden turning of the wheels can be effectively avoided. So the

security of driving can be improved.

※The load on the steering wheel is permitted to increase, which can improve the freedom

motion of the general arrangement.

The power steering gear of the steering system of A15LHD is a standard feature, and the
mechanical steering gear is optional.

In fact, the power steering gear of A15LHD is based on the mechanical rack & pinion
steering gear and enhanced with a set of power mechanism which is composed of the engine
used as energy sources, the steering oil pump, the steering control valve, the power oil
cylinder and other components. Under the working condition, the power of the engine drives
the steering oil pump through the ribbed belt. The power steering fluid (ATF oil) is suck out
from the oil reservoir by the steering oil pump and formed pressure oil to get into the control
valve. After distributed by the control valve, the pressure oil enters the power cylinder to
push the working piston which is connected with one end of the steering rack. So the steering
power can be formed by the pressure oil through the working piston.

If the power steering system is in failure, the steering of the vehicle can be also completed by
the driver.

The optional mechanical steering gear is a rack & pinion steering gear which the power
source is the physical force (strength of the hand) of the driver. All the dynamic components
are mechanical.

REMOVAL/INSTALLATION OF STEERING COLUMN

Removal and Installation of the Steering
Column

·Remove the nuts on the steering wheel

·Remove the upper and lower protector of the

instrument cluster and the switch

·Remove the instrument panel assy. (Please refer

to the removal of the instrument panel)

·Remove the joint bolt of the upper steering

column bracket and the car body upper bracket.

·Grind away the safety screw and replace with a

new one when installing.

·Remove the joint bolt between the steering gear

and the steering column (tightening torque:
30N·m)

·Install the steering column inversely according

to the removal steps.

The inner spline of the steering gear is

shown as the picture below:

Removal and Installation of Steering Shaft and Steering Tube

·Remove the clip.

·Take off the serrated set bush and the steering gear lock housing from the steering column

·Draw out the steering shaft and press the lower bearing of the steering column out with a

presser.

·Disassemble the lock housing spring of the bracket ring steering shaft with a presser.

·Assemble the steering column inversely according to the removal steps.

Precaution：

·Apply a little grease around the lower bearing and the inner wall of the steering hose

column lower end, press the lower bearing into the steering hose column using a
presser.(Do not move the upper and lower universal joint of the guard column)

·Adjust the relative height of the lock housing and the hose column according to the height

of the pre-installed ignition lock cylinder and the combined switch cover.

·Apply lithium base grease evenly around the contact ring.

REMOVAL/INSTALLATION AND CHECK OF STEERING GEAR

Lift the whole vehicle at a designated safe
place with a lifter

·Remove the high and low pressure oil tube
of the steering gear with torques of 45±3N·m
and 30±3N·m respectively.

·Remove the joint piece of the steering link

·Remove the shift shaft bracket

·Remove the front tube and the three way
catalytic converter with torques of 60±3N·m

Two bolts on one side of the steering gear are
shown as the picture below. Tightening
torque: 30±3N·m.

and 25±3N·m respectively.

·Remove the four bolts of the steering gear.

·Remove the fixing bracket of the steering

gear and the rubber hose.

·Install the steering column in the reverse

order of the removal.

Note:

The right picture shows the status of

the power steering oil tube of the steering

gear removed.

The tightening torque for the hollow bolt

which connects the high pressure oil tube

and the power steering pump is 45±3Nm.
