Check and Replacement of the Components of the Steering Mechanism

Check the steering rack piston assy（Refer to
Illustration 14）

Check(1)：Inspect the stagger of the rack 31 of
the rack piston assy, which the maximum value
is 0.15mm. Examine if there is flake or
indention on the rack surface and crack or
damage on the working surface. Check if there
is wear or damage on the back surface. Replace
the rack piston assy, if necessary. Check the
damage of the piston ring 32 and the O rubber
ring 33 of the piston. Replace both, if necessary.
Remove the piston ring 32 and O rubber ring 33
with a screwdriver.

Precaution：Do not damage the rack 31. Apply the power steering oil on the new O
rubber ring 33, and then install it. Enlarge the piston 30 with finger.

Precaution：Do not enlarge the piston ring excessively. Install the new piston ring 32 on
the piston of the rack piston, apply power steering oil on it, press it tightly with finger.

Check the bearing of the rack hull assy
（Refer to Illustration 15）

Check (2) ：

Examine if there is indention or

damage on the lower bearing 25 of the hull oil
reservoir assy 17 and if it can rotate freely.
Replace it, if necessary. Apply the white special
grease on the installation position of the bearing
when install a new one.

Check the oil seal of the stop collar assy.
（Refer to Illustration 16）

Check (3): Inspect if there is flake or indention
on the working surface of the oil seal 30 of the
stop collar assy and damage on the lip. Examine
if there is scratch on the inner surface of the
housing 34 and damage on the O rubber ring 28.
Replace the oil seal, housing or O rubber ring, if
necessary. Apply the white special grease on the
inner and outer surface when install a new one.

Valve core assy

Check (4): Inspect if there is crack, damage,
flake or deformation on the rack surface of the
pinion shaft of the valve core assy 13. Replace
the valve core, if necessary. Examine if there is
damage on the seal ring 8 of the valve core assy.
Replace with a new one, if necessary. Remove the
seal ring with a screwdriver when replace.

Precaution: Do not damage the valve bush.
Enlarge the new seal ring with a special
purpose tool and install the enlarged one on
the valve bush of the valve core assy and then
shape it with a set sleeve.

Check the conical connectors which are
connected with the hull assy (Refer to
Illustration 18)

Check (5): Inspect if there is scratch or damage
on the surface of the conical connectors 16 and 18
which are connected with the hull and the oil
reservoir connectors. Replace with a new one, if
necessary. When replace, remove the conical
connector with a special purpose tool and beat
lightly a new one with a plastic hammer.

Assemblage of the Steering Mechanism

Preparation:

Clean all components in clean organic solvents before assemblage, then dry them with a

blower

Precaution: Be careful during operation. The organic solvent is flammable and

explosive, keep it away from any tiny sparks. Otherwise, it may lead hurt
or even death.

Precaution: Make sure to wear the goggles while using the compressed air.

Lay the clean components separately and avoid the collision or scratch.

Replace all the oil seal, seal loop and seal ring. Apply the white special grease on the
O-ring and oil seal of the seal sections.

Get the replacing components ready every component must be qualified before

assemblage.

Precaution: When replace, all the set bolt, adjusting screw, seal component, lock nut

and the other components must be conformed to the technical specification
of Chery and can not be substituted arbitrarily.

Get the clean MoS

2

Lithium lubricating grease or the same performance grease ready

during assembling.

Precaution: If the unclean grease is used, the seal components would be damaged or

scratched, which will impact the steering power and result in accidents.

Assemblage

Precaution: Do not twist any seal components during assembling.
