Table 6
Cause    Solution    
The track alignment is not correct.     Adjust the track alignment.    
The belt tension is not correct.     Check the belt tension.    
The pressure of the air springs are not equal.     Check the pressure of the air spring. As required, inflate the air spring to the correct pressure.    
There is pilot pressure in NEUTRAL.     The steering control is not adjusted correctly. The pilot valve spool is stuck. The centering spring for the steering wheel is malfunctioning.    
The multifunction valves in the steering pump are malfunctioning.     Consult any CLAAS dealer.    
The control for the pump stroke is malfunctioning.     Consult any CLAAS dealer.    
The load on the drawbar is off-center.     Remove the pin for the swinging drawbar.    The Steering Wheel Rotation Is Excessive Before the Turn Begins

Table 8
The Temperature of the Hydraulic Oil in the Steering System Is High.    
Cause    Solution    
The oil cooler core is plugged or the air flow of the oil cooler core is low.     Clean debris from the oil cooler core.    
The oil cooler bypass valve is stuck open.     Replace the valve.    
You are using the incorrect oil viscosity.     Use the correct oil viscosity in the hydraulic system.    
The oil level is low.     Check the hydraulic system oil level. If the level is low, add oil to the hydraulic system.    
There is air in the oil.     Find the location of the entry of the air into the system. As required, repair components or replace components.    
There is excessive wear in the steering pump or in the steering motor.     Replace the steering pump or replace the steering motor.    
The multifunction valves in the steering pump are malfunctioning.     Consult any CLAAS dealer.    
The control for the pump stroke is malfunctioning.     Consult any CLAAS dealer.    
A line is restricted.     Consult any CLAAS dealer.    
The load on the steering system exceeds the capability of the steering system.     Reduce the load on the steering
