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 resistance

•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.
