D14 just dropped the clutch. HELP!!!

My wife was box scrapping the sheep feed lot and she said the clutch squealed for 5 seconds and then the pedal dropped. The tractor stayed in gear and needed to be shut off to stop. I opened up the
bell housing access hole and you can see that the fork slipped off of the throwout bearing. There are 4 tabs on the throwout bearing that hold it in place with the fork. I released the clutch lever from the
pedal and I could tap the throwout bearing around enough to get the fork to go back between the 4 tabs. I thought maybe it just slipped loose and needed to be relocated. Nope. Fell right off again. Back
to square 1. I split this tractor 3 years ago, replaced the clutch, pressure plate, and bearing. This problem just showed up today. What am I missing?
 
Sounds like a dry throw out bearing has seized and worn through the clutch fingers. There is no magic wand for that problem. Tractor needs to be split at the clutch housing. Figure on a complete clutch set and usually the flywheel will need faced.
This something happened regularly on a neighbor's D14 loader tractor because he never took his foot of the clutch. Given a good place to do it and the right jacks and blocking its a 1 day job.
 
If the throwout brg isn't turning hard (it was new, right ??) there is a bolt/nut that pinches the two fork levers together, and it may be loose, which allows the throwout brg sleeve/shifter to rotate. Those two fork levers could also be spread apart/bent which would also allow the shifter to rotate. The pinch bolt can be tightened up with come creative tooling if that's what the problem is.
 
Clutch fingers aren?t worn off, they are shiny, but not in bad shape. I?ve done a dozen clutches over the years, once the forks are back where they belong, I still have the 1/4? clearance required per the manual. The tractor has sat since November until yesterday. Is it possible that the bearing is dry? I haven?t attempted to spin it by hand yet, I will try that today.
 
Would a greaseable throwout bearing help my situation? Could the throwout bearing be drilled and a zerk fitting added?

Look: a good quality throw out bearing will last as long as a clutch does, PROVIDED the pedal freeplay is maintained AND you don't have your foot on the clutch pedal all the time. I've been doing this for 47 years and that is the way it is. Most Operators let the freeplay go to zero and then the throw brg fails OR the clutch starts to slip. Proper adjustment of the freeplay would have prevented the problem. Set freeplay at a max figure of 4 or 5 inches and as long as the clutch releases when depressed fully, leave it that way. As the clutch naturally wears, the freeplay becomes less and less until there is none.
