1864 PTO issue
 

It's always something isn't it? Fix one problem, find another. :bash2:

I finally got around to installing a deck on my 1864. I managed to remember how the mule drive was installed, man-handled the deck under there, got lucky finding a belt that fit in the barn... going smoothly for a change. Go to start the tractor and surprise, the blades start spinning. That shouldn't be happening. Flip the PTO switch, won't turn off.

So the PTO is stuck on. Been reading a bunch of other threads and it seems to almost always be a seized bearing or similar.

I took a little video of what it's doing, just hoping someone can confirm if this behavior is consistent with a seized bearing or if it might be something else- https://photos.app.goo.gl/ti8ghr3bsJgSPuEw8

Still took it out for a lap though, good news is that it seems to cut really well, especially considering the poor condition of the blades. I could not for the life of me get them off. Project for next weekend once I get this PTO figured out.

Run it through some tall grass and flip the switch on and off a few times. Sometimes you get lucky and have it break loose.

Bearing is stuck. You may get lucky if you can get some grease into it with a needle adapter. You stick it in under the bearing seal and pump some new grease into the bearing. then you will need to manually work the pulley to get it free. If that doesn't work it's replace the bearing or PTO time.

What Sam said....

Started driving it out towards some long grass, and basically as soon as I got in I hit a little 2-3" tree stump that was hidden. Blades stopped. Flip the PTO switch, blades start. Moment of truth, flip PTO switch off... it disengaged :beerchug:

Mowed about an acre, pto on/off a dozen times and it didn't stick at all.

But, knowing it was stuck and likely was not well taken care of in the years before my ownership, what should I try to do re preventative maintenance here? I should note I have no idea how long this tractor was sitting in the barn before I bought the place. If the original deck was any indication, quite awhile.

LOL.. well yeah. that kind of abrupt stop can do that. Glad ya sorted it out. I would try greasing the bearing the way Sam said. You might save that pto for a few seasons

Well, spoke too soon. I noticed as I was driving it around (w/o PTO engaged) that the belt was just barely moving. Then started moving a little more, then eventually seized up again.

So the question is, do I tear it apart and just replace the bearing? When I have it apart, what could I look for to determine if I should just replace the whole assembly?

If I were to replace it, is this what I would need? https://xtremeope.com/p/pto-clutch-f...gt2186-gt2523/
(good vendor? better one to buy from?)

(A) The vendor is very good.

(B) The 1864 used two different PTO Clutches. Make sure you order the right one.

Replace the bearings for what they cost, it's worth a try. I have not done an 1864 yet but all the others I have done were a 6206 double sealed. See if you can get some numbers off of the bearing or measure it.

I've used ones like these with no issues yet.

Finally got around to pulling the PTO. In a stroke of luck, it appears the bearing in the armature is seized. Knowing my luck, the PTO will be shot too, but better to start with the $15 fix than the $250 fix.
I don't have a bearing press, can I just hammer it out with a socket or something? Certainly don't want to damage the armature in the process.
