5.6 Adjustment of Steering System
5.6.1 Precautions for Use of Full Hydraulic Steering System (Hydraulic Check)
Lovol four-wheel drive tractor adopts full hydraulic steering, as shown in the figure. The steering system is
correctly adjusted before the tractor leaves the factory. Attention shall be paid to the following matters during use:
Check each thread joints frequently, and tighten them in time if necessary. When the full hydraulic steering
system works, there shall be no oil leakage at each joint.
During use, if heavy steering or failure is found, the cause shall be carefully found out at first. Do not pull the
steering wheel hard, and do not disassemble the steering gear easily to prevent parts from being damaged. It
is forbidden for two people to turn the steering wheel at the same time.
The steering gear shall be coaxial with the steering shaft and shall have clearance in the axial direction when
people are installing the full hydraulic steering system. Check the steering wheel for flexible return after
installation.
The oil must be clean. For this purpose, check the condition of filter element and oil frequently. Method:
Drop the oil on blotting paper. If the center of the oil spot is black, the oil needs to be replaced.
After that, exhaust the gas in the cylinder. Method: Loosen the bolt of the steering cylinder, and let the oil
pump run at a low speed for venting until there is no foam in the oil flowing out. Remove the connection
between the piston rod of the steering cylinder and the steering wheel, turn the steering wheel to make the
piston reach the leftmost or rightmost position (do not stop at the two extreme positions), and then fill the oil
tank to the specified maximum oil level.
