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 cases, 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 turnedLow 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

Function Code:
101 series steering units are one of our most popular type, founction available ON (open center non-reaction), CN (close center non-reaction), OR (open center reaction) and LS (load sensing).

Appliions:

Steering units have widely appliions, such as conveyor drives, agricultural machines, construction machines, transmission and lift equioment, etc.
