Toro Reelmaster 5100-D - Test No. 7: Reel Drive Motor Efficiency

TEST NO. 7: Reel Drive Motor Efficiency
Reel drive motor efficiency can be tested by blocking
outlet flow from the motor, then measuring flow from the
motor case drain line. Use a graduated container, such
as special tool TOR4077 to measure flow from the motor
case drain line over a 15 second time period (Fig. 23b).
Use the chart to determine the flow (Fig. 23c).
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for
approximately 10
minutes.
2. Lower cutting units, engage parking brake and stop
the
engine.
3. Disconnect the motor case drain hose (small diame-
ter hose) where it connects to traction unit (not at the
motor). Put a steel cap on the fitting at the traction unit.
leave the case drain hose open (Fig. 23a)
4. Disconnect hose from outlet of motor to be tested. Put
a steel cap on the motor fitting. Put a
steel plug in the
disconnected hose (Fig. 23a).
5. Set HOC Selector Knob, located under the instrument
panel, to
position A (full speed). Make sure Backlap
switch is OFF.

Keep away from cutting units during
reel blades. Do not stand in front of the ma-
chine.
CAUTION
6. Sit on the seat and start the engine. Move throttle to
full speed (approx. 3200 RPM). Move “Enable/Disable”
switch to ENABLE. Move “Lower-Mow/Raise” lever for-
ward to engage cutting units. Have another person
measure flow from the case drain line for 15 seconds,
then move the switch to DISABLE and stop the engine.
TEST RESULTS: Flow not more than 0.5 GPM.
7. If flow is more than 0.5 GPM motor is worn or
damaged and should be repaired or replaced.
