III. Control Valve and Bi-directional Hydraulic Motor Test

Flo-Check

FIGURE 9 - 

Control Valve and Bi-directional Hydraulic Motor Test

A.  Motor Test No Load

1.  Open the Flo-Check loading valve fully to read maximum pump 

fl

 ow at zero pressure.

2.  Select Run and/or Record on the PC (see Recording Measurements to a File on page 8).
3.  Put one control valve in the forward operating position. (If there are multiple valves, only one control valve 

should be in an operating position at any one time.)

4.  Using a tachometer run the motor with no load. The 

fl

 ow and RPM should match the manufacturer’s 

speci

fi

 cation. A decrease in RPM from the manufacturer’s speci

fi

 cations indicates a loss of the motor’s 

ef

fi

 ciency.

Note:  This test can be repeated for the reverse direction.

B.  Motor Test Loaded

1.  Open the Flo-Check loading valve fully to read maximum pump 

fl

 ow at zero pressure.

2.  Select Run and/or Record on the PC (see Recording Measurements to a File on page 8).
3.  Put one control valve in the forward operating position. (If there are multiple valves, only one control valve 

should be in an operating position at any one time.)

4.  Using a tachometer run the motor while providing a load on the motor. The 

fl

 ow and RPM can now be 

checked against the motor manufacturer’s speci

fi

 cations. A decrease in RPM from the manufacturer’s 

speci

fi

 cations or the unloaded motor test indicates a loss of the motor’s ef

fi

 ciency.

Note:  This test can be repeated for the reverse direction.

C.  Motor Test Simulated Load

1.  Reverse the pump 

fl

 ow.

2.  Open the Flo-Check loading valve fully to read maximum pump 

fl

 ow at zero pressure.

3.  Install one or both of the following instruments on the hydraulic motor.

a.  Place a Hedland Variable Area Flow Meter¹ on the case drain and manually record the 

fl

 ow as you 

increase the load on the tester. Then compare it to the manufacturer’s speci

fi

 cations.

b.  Place a tachometer on the motor’s shaft.
