TESTER HOOK-UP NO. 3
Motor Efficiency (motor with case drain)
With the control valve in the run position, and the flow meter in series between the outlet side of the motor
and the valve, we can measure motor efficiency. Disconnect the small diameter case drain hose. Use the
restrictor valve on the flow tester, to restrict flow coming out of the motor, then measure the flow coming out
of the case drain hose into a graduated container. (Oil must be at operating temperature for a valid test).
Measure how much oil goes into the container for 15 seconds, then multiply that result by 4, to get a flow
measurement in Gallons per minute, or Liters per minute. Too high a flow, indicates an inefficient, worn or
damaged motor.
