Clutch
• Measuring clutch coil resistance.
1. Turn the engine and PTO switch off.
2. Disconnect the clutch at the clutch
connector.
3. Set the meter to read ohms.
4. Connect the meter leads to the clutch.
5. Check the meter reading.
CMS-175 (237 Nm) = 2.45 - 2.71 Ω.
CMS-200 (271 Nm) = 1.74 - 1.93 Ω.
The values above are at 23°C (68°F).
If the reading falls within the acceptable
range, measure the supply voltage at the
clutch. If not, replace the clutch.
• Measuring the supply voltage at the
clutch.
1. Turn the engine off.
2. Connect the meter leads at the clutch
connector.
3. Set the meter to read volts.
4. Ensure that the wires will not become
entangled in the rotating parts of the
clutch.
5. Start the engine and engage the PTO
switch.
6. Measure the voltage across the leads at
the connectors.
7. The voltage should be 12 - 14 volts DC. If
the clutch still fails to operate, replace the
clutch.
8. If voltage is not within the 12 - 14 volt
range, measure input voltage and output
voltage at the clutch switch. Any drop in
voltage is unacceptable.
