Take an ohm meter and check the the resistance of the electric clutch. Should read 2.4-3.4 ohms. Sounds like the electric clutch coil is shorting out when it gets hot.
It's time for a new clutch!!!
Clutches can fail in either or both of these ways, the coil insulation can break down causing the coils of wire to short to themselves and the coil can short to ground.
If the coil shorts to ground, the path of least resistance is thru the crankshaft, the main bearings and then to ground.
You need to know both of these conditions, the resistance between the two coil wires and from either coil wire to ground.
Do the check from either coil wire to ground. This reading should be infinity or no continuity.
Although fairly rare, a clutch coil that has shorted to ground can cause serious internal engine damage as the electricity passes thru the main bearings can damage them and cause engine failure.
Let us know what you find.
Over the years I have torn down two engines that had main bearing failure due to a grounded clutch coil. The main bearing closest to the clutch is where the damage usually is found.
Blind Freddy job.
Disconnect the wire first and reconnect it last.
Look carefully at the anchor.
Some come in from under the clutch and will need to be removed while others just hang down and the clutch falls off.
Undo the center bolt which normally requires a deep socket preferably on the end of a rattle gun.
Don't shove your face directly under it as they are heavy and can suddenly drop off.
Check the main drive belt while the PTO is off as it is easier to change when the PTO is off.
Reverse it onto soe car ramps to give yourself room to move, just watch for the clutch dropping off the bolt into the end of the crank is the only thing that holds it on, apart from some rust.
Thank you bertsmobile1, I feel comfortable with changing the clutch with your in put, you never know what problems will show them selves. Glad to get the knowledgeable imfo.
