Steering wheel rotation, Tai'an biggest excavator school, can not return to the neutral position against this type of failure generally occurs after the repair or maintenance of steering gear apart reassembly, excavators school, because the relative position of the rotor with the coupling device installed wrong, Relationship disorder caused by steering with oil. Replace the casket should linkage, a sign marks the alignment of the rotor so that the linkage is splines splines. If there is no mark, it should make the deadbolt linkage groove center line is aligned on the upper end of the rotor centerline any teeth. (Continued a) 4) diverter valve failure, premature opening. Check valve spring is deformed or failure, Tai'an excavators school phone, if the spring force is insufficient, Tai'an excavator schools Which is good, it can increase the gasket between the spring and the seat. (5) spool and sleeve deformation, can cause both stuck. We shall go into the oil mouth of a small amount of hydraulic oil before filling installed, turn the valve should be flexible and comfortable, if catching phenomenon to be polished. Sometimes, when tightening the bolts at the bottom steering uneven force, there will be the phenomenon of the valve is stuck, the correct approach is 2-3 times evenly tighten the bolts.
