Update: SOS trans over full

So I made a new tube, which is very easy if you have a lathe.
I installed the tube, put manifold back on and filled the hydraulic reservoir first. Oil almost immediately start running out of the trans drain. I sure wish I would have tried that before I took the tube out. So, I split the tractor today to find the seal completely out of its bore, just sitting on the shaft. The pto shaft has quite a bit of end play and the trans output shaft is also over spec on the end play.

I've been studying my parts manual, but a lot of the part numbers in the illustrations don have a description so I don't know if there are shims on the pto shaft to adjust play or not. Any of you know?

And for the trans output shaft, it looks like there's a shim for the "C" sun gear that might take up the play I have. Any input on this as well?

I am hoping this doesn't snowball much more. But I know this is a 58 year old tractor that might need more TLC.

I think it is worth it. Under the red and then blue paint is the original gold on every part that I've checked so far. I kind of wish it wasn't a gold tractor because my heart says I need to repaint it to the original gold, but the red and gray is so darn pretty. Maybe I just need another tractor.
 
I have a Ford 981 demonstrator that has me thinking the same thing as paint color. I think the gold tractors are UGLY!!!! but they are more rare. The one I have is known to be an actual gold demo since it was never retail sold. The dealer kept it as a yard tractor until the gas engine died and they replaced it with a newer diesel tractor.
 

There are thrust washers on each shaft, but not shims. If you're way off on end play you'll need to do further diagnostics to determine the cause.
 
Larry,

There is one thrust washer in each compartment (forward and rear) that is selective in size in order to adjust component end play. As I recall, they were the rearmost shim in each compartment.
 

Yes. I guess one could call that a shim, because it is selective. But I don't think it's going to cure a problem like I think I'm hearing here.
 
After doing some measuring, I think if I use a .122 thrust washer on the output shaft, I can cure the end play there.

It doesn't look like there is a selective thrust washer, just a thrust washer, on the pto shaft, so I need to dig in a little further to see if the one that it shows in the parts book is actually on my shafted worn enough to warrant replacement.

The pto seal is no longer serviced but I think I've found one that'll work in metric sizing. 72 x 35 x 12. The shaft is 1.377. The bore is 2.833. And the original seal is .400 thick including the flange. The bearing in ther is a number 1207 and the simensions match up.

What's weird is there's a wear mark on the pto shaft where the seal would ride but the i.d. of the seal, that was in there, is bigger than the shaft itself, by .080". The parts diagram shows a sleeve of some sort that appears to go on the shaft which would take up the difference, but I have no dimensions to verify this and I'm not sure how that sleeve would be retained unless it is/was a press fit. The seal that was in there has a Ford insignia on it, but no part numbers.
