TROUBLESHOOTING
3-3-3. Steering wheel backlash or play is large
Check point
Cause
Check/Action
1. Orbitrol
Spline of orbitrol is worn.
Replace orbitrol.
2. Steering Wheel
Serration (spline) of wheel is worn.
Replace wheel.
3-3-4. 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. 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, check and adjust relief valve or
replace it if necessary.
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.
3. Suction Filter for
Steering • Vibrator
• Charge Pump
Load of steering pump increases due
to clogged filter, causing temperature of
hydraulic oil in circuit to rise.
Clean suction filter or replace it if necessary.
3-3-5. Abnormal noise from steering system
Check point
Cause
Check/Action
1. O i l L e v e l o f
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 specified torque.
4. Suction Filter for
Steering • Vibrator
• Charge Pump
Cavitation is occurring in charge pump due
to clogged filter.
Clean suction filter or replace it if necessary.
