Hydraulic Valve Solenoids - Toro Reelmaster 5200-D Service Manual

Hydraulic Valve Solenoids

Note: Prior to taking small resistance readings with a
digital multimeter, short the test leads together. The me-
ter will display a small resistance value (usually 0.5
ohms or less). This resistance is due to the internal re-
sistance of the meter and test leads. Subtract this value
from from the measured value of the component you are
testing.
1. Make sure engine is off. Disconnect solenoid valve
electrical connector.
2. Apply 12VDC source directly to the solenoid. Listen
for solenoid to switch on.
3. Remove 12VDC source from the solenoid. Listen for
solenoid to switch off.
4. Measure resistance between the two connector ter-
minals.
A. The resistance for a 20 watt coil should be about
7.2 ohms.
B. The resistance for a 28 watt coil should be about
5.1 ohms.
5. Install new solenoid if necessary.
A. Make sure o-ring is installed at each end of the
coil. Apply "Loctite 242" or equivalent to threads on
end of valve stem before installing nut.
B. Tighten nut to a torque of 15 in-lb (17.3 kg-cm).
Over-tightening may damage the solenoid or cause
the valve to malfunction.
Note: Each electrical harness connection for the
valve solenoids has a colored power and a black ground
wire attached to it.
