What do you need to know about a PTO clutch?
Testing the PTO clutch should be done with caution, using proper safety steps. The power takeoff clutch, or PTO, on a small engine uses electricity to engage a clutch to the main engine crankshaft. PTO clutches transfer rotational torque and power, typically used on small tractors to activate mower blades or tillers.
What happens when the AC clutch does not work?
An automobile can have numerous serious problems and a dysfunctional AC compressor clutch is one of them. When this component does not work properly, the engine does not get the cold air flow – leading to some major complications. Knowing how to manually engage AC compressor clutch will help you skip a visit to the mechanic.
Where is the clutch on a riding mower?
Lift the utility vehicle up with a floor jack. Place two jack stands under the front frame and two jack stands under the rear frame, so the wheels sit above the pavement. Provide enough clearance to look under the mower deck and see the clutch drive assembly. Refer to your owner’s manual for the battery location.
When to move on to the clutch relay?
Move on to the clutch relay if the fuse turns out fine. In a few car models, the power of the air conditioning system flows from the AC switch to the fuse before being transmitted to the clutch oil through the low-pressure evaporator temperature. You have to make sure that the compressor has enough oil to function properly.
How to test current draw on electric clutch?
If the machine has been in operation, the clutch must be allowed to cool completely before testing is performed. To test for current draw, begin by turning off the enigne. Disconnect the clutch connector from the wiring harness. Set the meter to test for amps (10 amp scale).
What are the components of an electric clutch?
Components An electric clutch/brake or clutch consists of three primary components: 1. Field Assembly The clutch’s “power” source contains the coil which generates magnetic force. Most common applications require a 12 volt DC coil, although other voltages are available. 2. Rotor Assembly Generally, the input of the clutch.
How do you test a PTO clutch light?
Place the probe of the test light inside the wire connector, attaching it to the red lead that leads to the PTO clutch. Activate the PTO clutch lever and look for the bulb to illuminate from the test light.
How does the clutch work on a lawn mower?
When energized, the magnetic coil in the clutch pulls the armature into contact with the rotor, which is attached to the engine crankshaft. The armature begins to rotate, turning the attached pulley, to drive the mower blades. When the voltage is turned off, the magnet releases the
