PTO switch is burning up within hours of replacement , connections clean , wires get hot at switch , resistance across pto clutch leads is 2.5 ohms. gap is correct . Do we need to replace the pto clutch ?

Sounds like either a bad connection someplace in the wiring, or there is a short in the clutch causes it to draw too many amps. Unplug the clutch and take a ohm reading between one of the wires and the medal part of the clutch. If you have continuity replace the clutch because you have a short. Have seen more than one clutch with a intermittent short, so you may want to replace the clutch just in case.

Thanks , Looked for short and found none , Bypassed all wiring and connected directly to 12v source - pigtail on PTO , the pigtail to the PTO gets hot when energized with 12v Replace PTO clutch or get coil kit and just replace the coil ? Thanks

Also looked for a ground as described from each lead to ground and found none , I am assuming the PTO coil operates on 12v . Thanks

May not be much difference in price between complete clutch and the coil pack with consist of over half the clutch assy anyway.

So you would recommend the PTO replacement plus another new switch . The last switch I put in smoked and now has an intermittent condition (only works cold , I imagine the contacts are burnt up a bit , and since they are sealed it would be a 20 dollar throw away item anyhow ) Thanks for your speedy reply I can go to SEPW and get pretty good price and shipping .

Where can you get just the coils for clutches?

A little more info on SEPW ,please

Just google sepw small engine parts warehouse of West Bend WI Has almost everything or can get it with a phone call

We get a few of these every season - still say a clean deck is a happy deck . These machines come to the shop so loaded with dead grass that the grass is hard and scorched from the pulleys and belts ...

Got the new clutch and switch SEPW only 3 days !

Clutch installation simple except instruction sheet mentions throw away rear engine mount bolt and replace with the one in the kit , The problem here is the new lever which holds the clutch from spinning is thicker than the original wire one and the new bolt is shorter . When you proceed to torque the bolt to 40 ft. lbs. the bolt will begin to fail at approx 32 ft. lbs. because it is a half inch shorter than the original bolt and it does not get deep enough into the threads to take hold . I suspected this when installing and watched the dial on the torque wrench like a hawk then stopped in time to save the threads on the engine . I installed the original bolt and torqued to 40 ft. lbs. No problem with the new bolt for the clutch itself . The Kit is an upgrade so you remove the clutch and spacer and pulley plus keys to install the new design .This is also not really clear in the instructions , Briggs really needs to rewrite the sheet ! all in all 15 minute job . Done Deal works great no more hot wires , a lot quieter too ! Thanks to all who helped !
