PTO switch had melted the casing so decided to install another one. After operating for 15 minutes the second PTO switch did the same. Yellow wires are the ones getting hot. wires go to ignition switch and the other to a relay. Any idea's

ANSWER: Hello Wally:
>>Test the PTO Unit.
>>The Following is a PTO Test File I made. Any Input is Appreciated. **If you have an Ohmmeter, Disconnect the Wiring Harness from the Front of the Clutch and Check the Resistance of the Clutch. You should have around 4 or 5 OHMs. If at or near Zero, the Coil has Shorted.**
>>The Following is a Basic File I made for Setting the PTO Clearance. Any Input is Appreciated. **Some of the Newer PTOs cannot be Adjusted.
>>If you can Get a Blade Style Feeler Gauge between the PTO Magnet and Clutch, then Set the Clearance at .015in. The Newer PTOs have the Same Set Up as the Older PTOs, except there is No Adjustments.
>>I Suggest also that you Rig a 12 Volt Light for Testing the Current Flow to the PTO while Operating the Mower. If the Light Blinks During Operation, then you have a Bad Connection somewhere to the PTO Clutch.
>>If the Light Stays Steady and the PTO Still Kicks in and Out, then it is the Adjustment.
>>You can Also Try Turning the Spring Loaded Adjuster Nuts 1/4 Turn and Operate the Mower. Do Not Adjust Over 1/2 Turn.
>>If you have Adjusted to 1/2 Turn and the Problem is Still Present and you Know the Voltage to the PTO is Steady, then Replace the PTO.**
>>From your Description it Sounds like the PTO is Pulling too Much Power and Requires Replacing.

QUESTION: John,
I connected the ohm meter to pto clutch and got no reading across black and yellow leads. I'm assuming this
clutch is bad but I have another Q for you. I'm having problems removing the 5/8's bolt on bottom of shaft.
Is this bolt threaded clockwise or counter-clock wise?
AnswerHello Again Wally:
>>It is Counter Clockwise to Loosen.
>>Remove the Spark Plug and Use a Bolt with the Same Diameter and Threads as the Spark Plug and About 3" Long.
>>Thread the Bolt into the Spark Plug Hole Until it Engages the Piston.
>>Slowly Tighten the Bolt Until you have Locked the Piston and it Does Not Move. **BE CAREFUL A LOT OF TORQUE IS NOT REQUIRED. PISTON DAMAGE CAN OCCUR IF TO MUCH TORQUE IS USED ON THE STOP BOLT**
>>Now Remove the Crankshaft Center Bolt from the PTO Clutch Assembly.
>>These Bolts are Hard to Remove Unless you are Using an Air/Electric Impact Wrench.
