Steering Valve Test (Control Valve Section)
Using Hydraulic Tester With Flow Meter
1. Engage the parking brake and block the front wheels
to prevent movement of the machine. Lower the cutting
unit or implement to the floor and turn the engine OFF.
2. Disconnect
the hydraulic hose at the charge pump
outlet (pressure) fitting.
3. Connect the inlet hose of the tester to the hydraulic
fitting on the transmission and the outlet hose of the
tester to hose that was disconnected in step 2.
IMPORTANT: Make sure that the oil flow indicator
arrow on the flow gauge is showing that the oil will
flow through the tester from the charge pump to the
steering valve.
4.
Make sure that the tester load valve is fully open
(counterclockwise). Start the engine and allow it to run
for approximately 5 minutes so that the hydraulic oil
reaches normal operating temperature.
5. With the tester load valve fully open (counterclock•
wise) run the engine at full throttle.
6.

(clockwise) and hold it against the right stop. Look at the
flow meter. There should be    no  flow as the steering
wheel is held against the right stop. Flow should be
approximately 3 gpm when the steering wheel is re•
leased. Repeat this procedure with the steering wheel
all the way to the left (counterclockwise). If flow does not
return to approximately 3 gpm when the steering wheel
is released the control valve within the steering valve
may be sticking.
