Front PTO clutch questions

[heinriech]

I tried my best to search and find the answers but couldn't.

My 782 with a magnum 18 in it has some issues with the electric PTO.

It's gotten worse after 2 days of snow blowing.

Sometimes the PTO will randomly disengage. Toggle still centered in engaged position.

Since the blower has been installed, I noticed that upon turning the PTO switch off the blower kept rolling at the same speed. I had to run the blower into the snow to get the PTO to stop turning. Had to do this A LOT because the QA42A blower was pretty much worthless until I coated the shoot with turtle wax.

Anyway today I was running it again and it was randomly shutting off. But today it was stopping turning. And after only about 15 minutes it wouldn't turn the blower anymore. It kind of looked like it tried to turn over but was not making the "click" sound and it would eventually stop. I also tried to hold the toggle in the up position and blow that way. No dice.

So without turning any wrenches any thoughts?

Adjust the PTO?
Remove PTO and exchange for a PTO off parts tractor, has series 1 kt17.
Remove PTO and put a rebuilt/new PTO on? (Probably not in the budget).
Push it out in the driveway and set it on fire to finish clearing snow that way?

Thanks OCC!!!!

Sounds like 2 problems:
the bearing in the clutch is bad causing it to continue turning.
It might have gotten so bad it took out the electric coil.
See if you have 12V. power to the clutch plug about 6" out of the PTO clutch in the "ON" position.
either way remove the pto clutch and inspect.

No, if your that frustrated with it, just send me your address and I'll haul the piece of junk off for you.

If you want to fix it, it looks like George has you headed in the right direction.

look up the air gap setting for the PTO in question and set it properly at all sides with a feeler gauge. It sounds to me like it might be out of spec. This would be your cheapest/easiest fix, it's free to check and adjust as needed.

Ok guys thanks. The pus it outside and set it on fire comment would of happened a long time ago. More of a joke than anything. We have a love/hate relationship!

Ditto to what ol' George said.

Does this happen while operating going forward or does it have to do with shifting from forward to reverse?

My 882 has the same issue as it is equipped with a reverse cutout switch.
Perhaps your machine has one as well.

Thanks for the input guys. I will see if I can find some time tonight to work on it. Will the PTO off the KT17 work on the magnum?

Thanks.

[ol'George]

Yes! they are the same.
And the bearing in them are replaceable,and easy to do, FWIW.

Ok so I spent about 30 ,minutes on this after work. First observance is that the pulley does not have any slop or wobble. It does spin semi freely. It does sound like metal on metal scraping when I turn it. When the motor is running I hear the same metal on metal scraping sound. I tried to follow these instructions:

I tried loosening the adjustment screws as far as I felt comfortable, 1-2 turns from the end of the stud. I still am not able to get a .010" feeler gauge in the inspection hole. I did not try anything lesser than .010". it looks like there are two steel discs that are spinning about each other, but no gap. Does the feeler gauge go the whole way in between these two plates or is the measurement taken way out at the edge?

Just trying to clarify what I should be looking for?

I also went and felt the one on the other motor and it's much stiffer to turn and the same amount of slop/wobble.

Let me know what you guys think?

Thanks!
