TROUBLESHOOTING
3-4-3. Steering wheel backlash or play is large
Check point
Cause
Check/Action
1. Steering Column
Spline of column shaft or orbitrol is worn.
Replace column shaft or orbitrol.
Column shaft bearings are worn.
Replace column shaft bearings.
2. Steering Wheel
Serration (spline) of wheel or column shaft
is worn.
Replace wheel or column shaft.
3-4-4. Steering system is overheating
Check point
Cause
Check/Action
1. Oil Level of
Hydraulic Oil Tank
Oil level in hydraulic oil tank is low.
Fill tank until correct oil level is obtained.
2. Oil Cooler
Cooling ef
fi
ciency is reduced due to clogged
oil cooler
fi
ns.
Clean oil cooler
fi
ns.
3. Steering Circuit
Pressure
If circuit pressure setting is excessively low,
relief valve is open, causing temperature of
hydraulic oil in circuit to rise.
• Measure steering circuit pressure.
• If low, replace relief valve.
If load is excessively heavy, relief valve is
open, causing temperature of hydraulic oil
in circuit to rise.
• Measure steering circuit pressure.
• If high, decrease steering load.
4. Suction Filter for
Steering Pump
Load of steering pump increases due
to clogged
fi
lter, causing temperature of
hydraulic oil in circuit to rise.
Clean suction
fi
lter or replace it if necessary.
3-4-5. Abnormal noise from steering system
Check point
Cause
Check/Action
1. Oil Level of
Hydraulic Oil Tank
Pump suction pressure is high because oil
level of hydraulic oil tank is low, causing
cavitation in steering circuit system.
Fill tank until correct oil level is obtained.
2. Steering Circuit
Cavitation is caused by air in circuit.
Bleed circuit.
3. Hydraulic Hose
Clamp
Vibrator sound of hydraulic hose is
generated because clamp securing
hydraulic hose is loose.
Tighten bolts of loose hydraulic hose clamp
to speci
fi
ed torque.
4. Suction Filter for
Steering Pump
Cavitation is occurring in steering pump due
to clogged
fi
lter.
Clean suction
fi
lter or replace it if necessary.
