I posted awhile ago about this and finally
got the tractor split. I found a wore out
pilot bushing letting the input shaft
wobble around. The clutch disc and pressure
plate are new. My question is on the
throwout carrier. It has the newer style
with the replaceable bearing. Where does
the throwout carrier sleeve go that the
carrier rides on? Is it pressed into the TO
bearing carrier and if so how does it get
lube? If I buy a new carrier does it come
with the sleeve?
 
The sleeve that the carrier rides on is pressed into the clutch housing. The stationary sleeve will not come with a new carrier. From your description, it sounds like the sleeve separated from clutch housing.
 
Yes the sleeve is loose and spinning inside the housing. It looks like someone tried tack welding it in place before. So I need to buy the TO housing and the sleeve. How does the sleeve get grease so it's not dry on the input shaft?
 
The input shaft does not actually touch the inside of the sleeve. The shaft is held concentrically aligned by the pilot bearing on the engine end, and by the flex joint at the transmission end. The grease fitting lubricates the sliding of the TO housing on the sleeve, which is supposed to be stationary. I don't think that a new sleeve is going to help you because the hole in the clutch housing is probably wallowed out. Without seeing it, I would say have a machinist come out and take a measurement of the hole, and make a new sleeve a couple thousandths larger O.D. on one end, for the length that it presses into the clutch housing. Or, to be really, really right, take the clutch housing to the machine shop and have it rebored, bushed, and the original size sleeve installed.
 
... or if it's reasonably close, have him knurl the end of your old sleeve, so it fits tight, and glue it in with red lock-tite.
 
Ok I see where it goes. The previous owners tack welded it in front of the bore that it should be pressed into. Their welds failed so everything was loose. I tried inserting it into it's place and it didn't go by hand so hopefully it's not wallowed out. I will get the new one and hopefully it fits tight. How far should it be pressed into the clutch housing? Does it bottom out or how do I know when to stop? I tried attaching a photo of the wore out pilot bushing just in case anyone wanted to see.

Look down the hole and see if there's a step. If there is, just push it in till it stops. No step? Measure the distance (on the old sleeve) between the end of the sleeve and the tack welds. Scribe this distance on the new sleeve and push it in only this far. The fact that you can't push it in by hand is encouraging. Degrease the parts (ether works good for this) and apply loctite both in the bore and on the end of the sleeve,this will evenly spread the loctite on the I.D. and O.D. surfaces as it is driven in for maximum gripping force. If the old one fits as tight as you say, you won't be able to dynamite the new one out of there.
While you're at it, make sure the throw-out bearing and the clutch are compatible. I used to have trouble with Ford F250s, '83-'86, they had a diaphragm spring in the clutch cover. The throw-out bearing was barely large enough to catch the ends of the fingers, and sometimes the T.O. bearing would wear a step in the fingers and get caught. The bearing was then forced to orbit with the spring, and this action would break the sleeve off the front of the trans.
