4.5 Steering System Adjustment
4.5.1 Full Hydraulic Steering System Cautions
The XT series four-wheel drive tractor uses a full hydraulic steering system, as shown in the figure.
Before leaving the factory, the steering system of the tractor is adjusted. Pay attention to the
followings during use:
• Check the threaded connections frequently and tighten them if there is any looseness. There should not be
any leakage at the connection when the
full hydraulic steering system is working.
• If any steering difficulty is found or there is a steering failure during operation, inspect for the cause first. Do
not turn the steering wheel too hard or dismantle the steering gear to prevent the parts from being damaged.
Never have two people turn the steering wheel together.
• While installing the full hydraulic steering system, the steering gear should be coaxial to the
steering shaft and there should be some clearance between the axial directions. Check the
steering wheel for flexible resetting after the installation.
• Ensure that the oil is clean. Check the condition of the core and oil of the filter frequently. Checking method:
dribble a drop of oil onto the a paper towel, and change the oil if there is a black spot in the center of the oil
mark.
• The diverter valve is a precise part which should not be removed except in a clean environment. It should be
cleaned with clean solvent.
• Before leaving the factory, the pressure of the diverter valve is adjusted. Do not dismantle or adjust it by
yourself. Replace if bad.
