Update: the JBWELD did its job.
No leaks .
:worthy:
So today I clean and organize the shop again, clutter = stress, then I’ll split the tractor to address the clutch again.

:help:
I swear to God I feel like putting a match to this thing!
Yesterday I split the tractor, again. Pulled it all apart and put it back together today, again. The fingers are all adjusted to 1-1/4" and the TO bearing sits 1/8" back. I pull the clutch pedal and watch it lift off the plate. The springs are not fully compressed at rest.
Fired it up, press the pedal and the SOB still won't release ! Damn !
Is the pilot bushing grabbing? It's not new and has done its job for many years. If it's whipped is that it? I shut it down and rolled the tractor in neutral and see no movement in the engine.
I'm at my wits end with this thing. Wasn't ever one to throw wrenches but I was there today. It's got the better of me and it isn't pretty. I have more important projects to get done but this little tractor was my first and I'd hate to roll it out to join the others "that don't run and will be fixed one day."
I don't want to walk away from it again with out it going back in service.
I know I'm going to have to split it a third time and all I can think of is to throw money at it and replace it all, pressure plate, disk, TO bearing (go back to graphite) and the pilot bushing.
Another thought you guys don't grease yours right (pilot bushing) ?

So sorry you are having this trouble!
And I have a hard time believing that a older pilot bushing that has been working fine now doesn't? Am I hearing that right?

I am grasping at straws here.
There are things I was sure of yesterday but not so much now. I’ve done this job before and had this once with a new bushing. I split it, reamed it and it was fine for 7+ years. I really don’t know what I’ve done different. All I can think is will a worn out pilot bushing grab? Is the pressure plate worn out?

Has this tractor ever operated properly with the ball bearing TOB?

Nope that’s why I said I’m moving to buy all new including the graphite TO bearing

I hope going back to original solves the problem.

I hope so too but you’d think it would at least release. Not releasing was why I tore it down in the first place so I feel like the new TO bearing isn’t the problem. The pressure plate or pilot bushing weren’t changed and the original problem hasn’t changed either.
Looking at the pressure plate I can’t see an obvious thing wrong with it.
A new pilot bushing is about $11 so it’s getting changed too.
Could the pilot bushing be doing it???
Don’t know but I’m not splitting it 4 times if I can help it so I’m just falling back on what I know worked in the past.
If it doesn’t work then I might follow Elvis’s example of when his Pantera wouldn’t start. ;)

So, it was doing this when it still had a graphite TOB? In your work on it, I assume that you physically separated the clutch disk from the flywheel at some point? In other words, the disk is not rusted to the flywheel?

Mike,

Last year I replaced a pilot bushing in a Farmall BN.

The bushing was trashed for some reason.

But what was happening in my case, is when I pressed the clutch in fully, the clutch would make a noise to where you knew something was wrong, and you could not put it in gear!

What I found out was the pilot bushing was like partially shreaded and the transmission input shaft would wobble around with the clutch pedal depressed and the clutch disc as it was wobbling around too, was catching on the recess in the flywheel!

Is your tractor making any unusual noise while you press the clutch pedal?

With your tractor engine OFF, sit in the seat, put your pto in gear, then push on the clutch and try to turn the pto shaft by hand. It spin ok?
