The Adapter Saga Continues

[Mark_in_NH]

Well !!! The mystery of my stuck PTO adapter has been solved. PARTIALLY !!
I was able to remove the pin and the spring and found that it had nothing to do with the adapter being stuck on the PTO shaft. The reason I know this is because the adapter is still stuck.
It is loose, it wiggles, it just won't slide off. I have even put a 3' wrecking bar on it to try and pry / force it off. I can apply enough strength to flex the wrecking bar, but the adapter stays put. The only thing that I can think of now, is that (as someone mentioned) there is a burr or some obstruction that I can't see causing the problem.
BOY, it must be one heck of a burr !!

You might want to try a gear puller. You can get the screw type, or the slide hammer type. With a puller you will be much less likely to damage anything.

I know you may have already checked for this, but is there a set screw anywhere? possibly recessed?

You say its loose - in what direction though? Is it sliding a little along the splines (in and out)? Is it rotating a little? How much play are we talking about - is it 1/8 inch or just detectable?

I have to admit that it sounds to me that if there is a good amount of play but it still wont come off then there may be some debris in there and not just a burr.

Not that I can see anywhere !

As in loose I mean. It will wiggle around, so I know it is not siezed onto the PTO shaft. It will slide back n forth along the PTO splines, ?maybe? a 1/8 inch.
I can look into the hole that the pin came out of and see movement, I don't see anything clearly evident in the way of a burr, obstruction or debris. I can look into the end of the adapter and see the end of the PTO shaft and again, I see no clear cause.
I think a gear puller may well be my next best tool to attempt removal. I also think that before I try that, I will buy a can of carburator cleaner and just spray clean the works just to make sure there isn't a little grease or something hiding the cause or culprit.

Maybe the problem is not the PTO/shaft spline connection but the slip joint in the shaft itself?? A bent shaft would cause that joint not to move. Is the implement still attached to the tractor? If yes, detach it and slide it back one joint or the other should move.

I've also seen over running clutches with a captive ball and spring style detent, that is not evident from the outside of the housing ( was internally milled and mounted.
The ball may have become rusted in place, or deformed, etc.

Is there a slip collar with this unit ( quik connect? )

Here is the same picture of the adapter that I posted in my earlier thread on this subject.
The only differance is that, Now there is no pin in place, ie. the round ended push button prtruding to the left of the adapter.

Even typing this it sounds silly - but have you tried running the pto with it as it is now to see if something will shake loose? If it's loose enough to rattle - maybe running it at 540 rpm will sling something and let it come off ---- I wouldn't advise anything or anybody be behind you at the time.

Mark,

You did remove one of those "retaining bolts" didn't you...?[img]/w3tcompact/icons/smile.gif[/img](one towards the tractor-through the PTO spline)

You may also check for a "hidden compressed lock pin" through your adaptor and tractors output PTO shaft/spline...

There is basically nothing left... [img]/w3tcompact/icons/wink.gif[/img]
