Illustration 23

 

·  Install the new conical connectors 18 and 16 
on the ends of      the left oil tube assy 19 and 
right oil tube assy 27. 

·Tighten the left and right oil tube assy with the 
tightening torque of 15~25N.m 

   

 

 

Assembling and adjustment（Refer to 
Illustration 24） 

·Adjust the adjusting plug 21 with a special 
purpose tool. 

· Cover the input shaft with the crank handle 
and rotate it to feel if it turns smoothly. 

·Apply the 5242 sealant on the 1/4 circle thread 
of the adjusting plug 21 which is close to the 
hull, fix the adjusting plug and screw the lock 
nut 20 with the tightening torque of 40~50N.m 

 
 

If it is easy to adjust the lock nut of the rack holder, it is not required to remove the 

★

steering gear from the vehicle. Therefore the adjustment can be completed on vehicle. 

 
a）Check the clearance 

Pull the steering tie rod to make it swing back and forth by hand to ensure that there is no 
clearance between the rack and the pinion shaft.   

Hint: It is not needed to adjust it if it is normal during the check. 

b) Adjust the lock nut of the rack holder to eliminate the clearance

 

If there is the clearance, loosen the lock nut 18 and screw the adjusting plug 19 clockwise 
until the clearance can not be felt between the rack 29 and the pinion shaft. Screw the 
adjusting plug 19 back about 30º~40 º, and then apply the 5242 sealant on the lock nut 18 and 
screw it with the tightening torque of 40~50N .m.

Install the rack lock-plate and the inner ball 
joint assy（Refer to Illustration 25）

Illustration 25

·Apply Kerui 5242 sealant on the thread of the 
inner ball pin.   

·  Install and screw the inner ball joint assy with 
a special purpose tool. The tightening torque is 
70~90N.m. 

 

 

 

 

Install the protector, outboard joint assy and 
single ear no-level clip（Refer to Illustration 
26） 

·Apply the grease on the lip of the protector 5, 
and then install the hull oil cylinder assy and the 
inner ball joint assy 7 in it. 

·Clip the big end of the protector with the single 
ear no-level clip 6. 

·Clip the small end of the protector with the 
clamp 4. 

·Install the rod lock nut 3. 

·Screw the outboard joint assy into the inner ball joint assy.

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.
