I live in North Central Nebraska and I'm having problems with my SOS. Is there anybody still around in this area who works on these?

Dunno about up there. Transport it down to me, and I'll work on it.
If you say more about what tractor it's in and what your symptoms are, perhaps we can help you help yourself.

It's in an 871 diesel. I just got through having to switch out the rear end because the guy I got it from had cracked it in two places. I bought this a year
ago as a project and boy has it been one. So the other day as I was test driving it and went to switch gears it wouldn't. The shifter works but won't go
into any gear. The PTO was already not shutting off. Where are you located BTW?

Let me answer this backwards. If you were on modern view of this forum , you'd see my location in the moniker. Anyway, it's Washington, Kansas.
Your PTO is acting normally for one of these. They have no PTO brake. Are you saying the PTO still spins after the tractor won't propel itself? If so check the traction disconnect coupler. It may have become disengaged.
If your PTO is not running, it may have shucked the torque limiting clutch or the input shaft splines.
Did the tractor make any particular noise when it quit moving?
Do you hear transmission shift noises when you change gear ratios?
Is your transmission oil clean, full and of proper spec?
What is the raised casting number on the left side of your transmission? Is it 312259? Or is it C3NN 7006 B?

I had the same thought about the fluid level and will begin by checking that. I'm a newbie at this and have seen a lot of discussion on what fluid these trannys use, what's your opinion? The PTO free spins and doesn't stop even with a load. I'll also check the disconnect though it was in the correct position.

Okay here goes. The casting number on the transmission is C3NN-7006-B, BCWCT, FT35(not sure about the T&3). The fluid is low so let me know what
I need to add. The rear end that I got from the salvage place and put on has casting number 1A24, CONN4024F is there anything you can tell me about
this rear end?

I wish you were closer, Larry.
I've just about given up on my 64, 4000 SOS retirement project and do not think I'll tackle overhauling the SOS, which I would want to do before installing the converted NG (high compression) 192 that should be good for about 65 PTO HP. Just getting too old.
I know of no one in my area that I would trust to overhaul it for me.

Someone who follows those date numbers closer than I can peg that rear end for you. I'll take a wild stab at it, and say it was built on the day shift of January 2, 1964. Did I come close, guys? In other words it's out of a later tractor than an 871. I'm going guess a 4 cylinder 4000.
Oil: Where did you check the oil? It's not the hydraulic dipstick in case you didn't know. It's a pipe plug under the front of the right footrest in the side of the transmission case.
Mine all get Archer Uni-Fluid XP. You may have a distributor within reasonable distance. Click here: [b:d4ccd07a00]Archer Dealer Locator[/b:d4ccd07a00]
At any rate, make sure that it "meets or exceeds" the old Ford M2C-41A spec or the current NH M2C-134-D spec.
PTO may be as simple as a cable adjustment.
On the plus side, you do have the "[b:d4ccd07a00][color=blue:d4ccd07a00]Blue[/color:d4ccd07a00][/b:d4ccd07a00]" or DDC transmission, which is a great upgrade from the original.[/quote]/url]

What's wrong with yours, Dean? Or did you just want to go through it and make sure it's all up to snuff?

I did check in the right place. It has the 90degree pipe many people say was added. Nonetheless I'll get the oil added and see what happens. I've got my
fingers crossed that that is all it is. I figured that rear end was off a later model because the casting has some horizontal ridges across it that I hadn't
seen on any 01 models.

The engine casting tells me that it was a 58 or 59 engine. Since the SOS came out in 59, I deducted that this was a 59 non-demonstrator. I've been told that since I've not messed with the SOS before, not
to mess with trying to adjust the PTO; is that good advice? I'm heading
out to the farm to add the oil to the tranny and will let you know what the outcome is.

It works fine, Larry, but the tractor has lots of hours on it and I'm certain that the transmission has never been overhauled.
I would not want to put it behind the HC 192 without overhauling it first. Moreover, I have no idea what the input shaft looks like.
The 4000 was intended as a retirement project, not as a user. The engine should produce about 65 PTO HP and I have a complete set of duals and a complete set of F & R weights that I was going to install for looks.
The tractor also has PS and dual remotes.
It's basically a toy.

I'd certainly not worry about PTO until I find out what, if anything else, is wrong with the transmission. And only then if I knew the procedure.

Sounds sweet. You can do whatever you wish. However, were it me, the only thing I'd do to the SOS is change oil and filter and adjust the bands. If . . . and I think that's a big if . . . it ever causes trouble, it's not that much to split that tractor or pull it out for a tear down.

Well, it was low on fluid and so I added it up to full. Even then it tried to engage in reverse, 4th, 8th and 10th but still wouldn't move. I think I'm at the
point where I need to visit with you on the phone about possibly bringing it to you. If you'd like to call me my # is 979.540.7260
