Hydraulic Steering Unit Safety precautions OSPC, OSPB, 101S, 102S, 109S

 

 

 

Safety precautions

Always consider safety precautions before beginning a service procedure. Protect yourself and others from injury. Take the following general precautions whenever servicing a hydraulic system.

 

 

Hydraulic Steering Unit OSPC, OSPB, 101S, 102S, 109S 0


Warning
Unintended vehicle or machine movement hazard.
Unintended movement of the machine or mechanism may cause injury to the technican or bystanders. To prevent uintended movement, secure the machine or disable/disconnect the mechanism while servicing.

 

 

Warning
Flammable cleaning solvents
Some cleaning solvents are flammable. To eliminate the risk of fire, do not use cleaning solvents in an area where a source of ignition may be present.

 

 

Warning
Fluid under pressure
Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious injury and/or infection. This fluid may also be hot enough to cause burns. Use caution when dealing with hydraulic fluid under pressure. Relieve pressure in the system before removing hoses, fittings, gauges, or components. Never use your hand or any other body part to check for leaks in a pressurized line. Seek medical attention immediately if you are cut by hydraulic fluid.


Warning
Personal safety
Protect yourself from injury. Use proper safety equipment, including safety glasses at all times.

 


Warning
Product safety
Steering units are safety components and therefore it is extremely important that the greatest care is taken when servicing these products. There is not much wear on a steering unit and therefore they normally outlast the application they are built into. Therefore the only recommended service work on steering units is:
• Changing shaft seals and O-rings
• Disassemble, clean and assemble if contaminated
• Make hydraulic testing including valve setting

 

 

 

Common causes of failure and troubleshooting

 

ProbleM Causes Troubleshooting
Oil leakage on the joint surface between the steering unit rear cover, stator and valve body rear cover stator bolt looseness (or uneven force), or O-rings damaged Evenly tighten the bolt, replace the seal
Oil leakage at steering shaft Excessive wear or damage of the seal ring at the shaft of steering unit Replace new seal
feels light when turn the steering wheel slowly, feels heavy when turn the steering wheel quickly Insufficient oil supply from the oil pump to the steering unit Check whether the oil pump is working properly (including liquid level, oil pump efficiency, pipeline smoothness, etc.)
There is foam in the oil, irregular sound, the steering wheel turns and the cylinder does not move There is air in the steering system

Eliminating the air in the system,

Check the suction pipe leaks or not, Or if the return nozzle is below the liquid level

Heavy steering continues to occur The oil in the tank is below the specified position Add oil to prescribed height
Oil viscosity is too high Use oil as required
Fast and slow steering wheels are both heavy, and there is no pressure on steering Check valve of the P and T fails

Check the ball.

If the steel ball is missing, then insert the steel ball;

If the ball gets stuck dirty, it should be cleaned;

In both cases, it is necessary to check the effectiveness of the sealing tape recovery.

No load or light load turns light, increase load turns to heavy Relief valve is of system's pressure lower than required value Adjust the pressure of the relief valve to the specified value (but not more than 16 MPa)
Relief valve stucked by dirt, Or spring failure,Or seal is damaged Clean the relief valve (check the effectiveness of the sealing tape), or replace the spring or sealing ring
Steering wheel cannot be automatically centered Spring broken or deformation Replace with new spring
Steering wheel rotates or swings left and right automatically Rotor and the linkage shaft are in the wrong position

Stop immediately!

Align the rotor and linkage shaft

Can not reach an end position Low pressure on relief valve Properly increase the pressure of the safety valve (it is best to adjust with a pressure gauge)

After turning to the end, the steering wheel can still be easily turned

Low pressure on shock valves Properly increase shock valves pressure (it is best to adjust with a pressure gauge)
when machine is off, turn the wheel, cylinder not move radial clearance or axial clearance is too large between radial and stator Replace rotor and stator
Low viscosity of oil Change oil
Slow cylinder action shock valves failure (ball caught by dirty, or spring failure, or seal damage) Clean shock valves, replace spring or seal
Pressure of Steering system not able to be adjusted Spring broken Replace the spring
Safety valve sealing quality is not high Replacement parts
Spool blocked Take out, check, and refurbish
Poor spool action Check whether the spool is blocked
Spring bent or too soft Replace the spring
Oil is not clean and the spool hole is blocked Replace clean oil and clear spool holes
