CHECK OF STEERING SYSTEM

REGULAR INSPECTION

Initial Check

·The maintaining staff should pay attention to the steering system troubles reflected by the

user first. In this way, it could save a lot of repairing time. For example, as the user
complains that the steering is heavy, it is necessary to clear that it is heavy on left or right;
or on spot; or discontinuous heaviness or even no steering power at all.

·If possible, try to drive the vehicle under the available condition in order to get the direct

sense about the troubles complained by the user. After the trouble confirmation, do not
hurry to remove the steering gear or the fuel pump as the other components of the steering
system may cause the troubles in fact. Please check these components first and then the
steering gear.

·First, check if there are proper, equal and conform to the standard.

·Second, check the front wheel alignment (caster, king pin inclination, camber and toe-in)

and the tightness of the steering tie rod, joint and king pin.

·If the oil tubes have been replaced by consumers, the following cases must be taken into

consideration: installation in a wrong way; too small diameter of the tube; clogging;
twisting or overbending which would cause the unsmooth flowing or insufficient flux. The
unqualified oil tubes must be replaced.

·Next, check the power steering oil reservoir and make sure that the oil level reaches the

specified point.

·Check if there is bending on the steering column; Wear or damage on the safety coupling;

invalidation of the spring elasticity. Repair or replace, if necessary.

Basic Check

---- Check if the set bolt of the steering system is loose.

---- Check if the free play of the steering wheel is appropriate. If necessary, check, adjust or

replace the components of the steering system.

Overhaul of the steering tie rod

---- Check if the steering tie rod ball joint is loose inside. Replace it, if necessary.

---- Check if the steering tie rod dust cover is damaged. Repair or replace it, if necessary.

Overhaul of the steering gear

---- Check if the dust cover of the steering gear is broken. Replace it, if necessary. Otherwise

the water and dust will enter the cover easily which would result the initial damage of
the components. Check if the clamp of the dust cover is fixed firmly.

---- Check if the clearance of the steering gear is appropriate. Adjust it, if necessary.

N-18

Overhaul of the hydraulic power pump

---- Check if the hydraulic power pump is clogged. Replace it, if necessary.

---- Check if there is abnormal noise in the hydraulic power pump Replace it, if necessary.

----

Check if there is leakage in the hydraulic system.

Replace it, if necessary.

CHECK OF THE SEAL OF POWER STEERING SYSTEM

Please follow the below steps:

·

Turn the steering wheel quickly to the left and right limit position and keep it immovable,
which can make the internal system pressure reach the maximum. Please pay attention to
the stay time.

·Visual inspect if the steering flux control valve, rack seal, vane pump(power steering pump)

or oil tube connectors leakage. Replace the seal components, if necessary.

·

Check if the ATF oil of the oil reservoir is enough. If it is shortage, inspect if the seal of the
power steering system is available.

·

If all the rack & pinion in seal components of the power steering gear housing are not
available, the ATF oil may flows into the bellow housing. Therefore, disassemble the
steering gear and replace all the seal rings.

·

Check if there is leakage in the oil tube connector. If necessary, find out the cause and

reconnect it.

Oil pump flow test

·

During inspection, turn the steering wheel to the limit position and apply enough force on
the wheel to ensure that the control valve of the steering gear can function normally.

·

When the engine is idling and the oil temperature range is 50℃±5℃, measure the flux of
the fuel pump and compare the reading of the flow meter with the specified value.

·

Next, adjust the rotating speed of the engine to three times as much as the idling speed and
repeat the test mentioned above. If the flux of the fuel pump can not return to the original
position immediately, it also shows that the oil pump works abnormally which could lead
to the instant failure or the discontinuity of the power. If the value of the internal leakage is
larger than 1.2L/min, the steering gear should be repaired.

Precaution: All the tests should be carried out when the engine is hot.

N-19

CHECK AND REPLACEMENT OF THE HYDRAULIC POWER OIL

Check the hydraulic power oil

----Repeat turning the steering wheel from one

limit position to another when the engine
is idling in order to increase the
temperature of the power steering oil to
40~80

℃

----Check the oil volume left in the oil

reservoir, the oil surface should reach
“max” mark of the reservoir. When the oil
is not enough, please check there is no
leakage of all the parts, otherwise fill with
the oil to the “max”.

Precaution: It is recommended to use the special machine for vacuumizing the injection
when filling with the power steering oil. Otherwise (for example, when the vehicle is
repaired). The specifications for filling the power steering oil and exhausting are shown
below: fill the oil reservoir with the power steering oil to the maximal position first, and
then start the engine at low speed (idling) to drive the steering pump so as the steering
system is full of the hydraulic oil. The engine must be kept in idling status to drive the
vane pump during refueling and meanwhile refueling continuously to avoid inhaling the
air of by the vane due to the fall of the oil level.

Replace the hydraulic power oil

---- Lift the vehicle to discharge the oil left in the oil reservoir and backflow hose.

---- Keep the engine idling, discharge the oil and meanwhile turn the steering wheel to the

end position until there is no hydraulic oil left.

Precaution: All these steps should be finished as soon as possible to avoid damaging the

hydraulic power pump.

---- Add the power steering oil.

---- Discharge the air completely in the hydraulic system.

EXHUAST OF THE STEERING HYDRALIC SYSTEM

---- Check the oil level. Fill with the oil, if necessary.

It should be exhausted as the hydraulic oil in the oil reservoir is emulsionized or the noise

of the pump is extremely loud (generally the maximal is 80 dbs) .The steps are shown
below:

Lift the vehicle, start the engine and turn the steering wheel left and right to the limit
position (Precaution: Do not keep stay on the limit position. If necessary, keep it less than
