    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.



    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


    ProbleMCausesTroubleshooting
    Oil leakage on the joint surface between the steering unit rear cover, stator and valve bodyrear cover stator bolt looseness (or uneven force), or O-rings damagedEvenly tighten the bolt, replace the seal
    Oil leakage at steering shaftExcessive wear or damage of the seal ring at the shaft of steering unitReplace new seal
    feels light when turn the steering wheel slowly, feels heavy when turn the steering wheel quicklyInsufficient oil supply from the oil pump to the steering unitCheck 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 moveThere 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 occurThe oil in the tank is below the specified positionAdd oil to prescribed height
    Oil viscosity is too highUse oil as required
    Fast and slow steering wheels are both heavy, and there is no pressure on steeringCheck 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 s, it is necessary to check the effectiveness of the sealing tape recovery.

    No load or light load turns light, increase load turns to heavyRelief valve is of system's pressure lower than required valueAdjust 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 damagedClean the relief valve (check the effectiveness of the sealing tape), or replace the spring or sealing ring
    Steering wheel cannot be automatically centeredSpring broken or deformationReplace with new spring
    Steering wheel rotates or swings left and right automaticallyRotor and the linkage shaft are in the wrong position

    Stop immediately!

    Align the rotor and linkage shaft

    Can not reach an end positionLow pressure on relief valveProperly 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 valvesProperly increase shock valves pressure (it is best to adjust with a pressure gauge)
    when machine is off, turn the wheel, cylinder not moveradial clearance or axial clearance is too large between radial and statorReplace rotor and stator
    Low viscosity of oilChange oil
    Slow cylinder actionshock 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 adjustedSpring brokenReplace the spring
    Safety valve sealing quality is not highReplacement parts
    Spool blockedTake out, check, and refurbish
    Poor spool actionCheck whether the spool is blocked
    Spring bent or too softReplace the spring
    Oil is not clean and the spool hole is blockedReplace clean oil and clear spool holes
