Guess I'd rather use/follow a manual than go by some video posted by a potential goofball who babbles endlessly and wobbles the camera around 'til it makes you seasick.

Shouldn't be too tough, or "rocket surgery" unless some "hard parts" that are no longer available are needed, IMHO.
 
That would be great if there is something like that available. Please post back if you find one. Would be beneficial to many who have them and if done correctly. Good idea......
 
There is an SOS section in the service manual. Parts are a challenge as many are NLA from Ford/NH. You can make most gaskets. Salvage yards can
provide some hard parts. Plan on spending longer finding parts than working on the transmission.
 
I completely went through my SOS last winter. It took all winter. I had to make some special tooling in the lathe to assist disassembly of some of the clutches.
I found the high pressure hydraulic tube bent and dislodged from the back wall of the case. Had to make a new one of those. I think it would be a long movie. The service manual is mandatory. Dozens of O-rings.
 

I have a manual for it but reading words and watching it are two different things, I have an idea itll take me a while, mainly after replacing the bands themselves so I was looking to see how it came apart first to see if I could change those out without much other disassembly first.
 
I understand how you feel, but my suggestion would be to get started and have the manual right alongside you
as you tear it down. I'm not aware of any good tear down videos out there, and if there are, they're likely
done by backyard hacks anyway who don't know much more than you do.

That said, I'm curious as to why you think it needs new bands? I've worked on my share of those
transmissions, and have never had to replace a band. They are pretty tough.

Virtually everything in that transmission comes out the back, so if you do have a legitimate issue inside,
start with a rear split and rear end disassembly.

Sorry! Bands are some of last components to come out.
 
I have an early one sitting in the iron pile for junk man. Over running clutch and #1 band are shot. It is from an 871. Churchville NY. Free for takin if we have time for a conversation.

My understanding of how these work is limited compared to the usual standards. The tractor slips in the lower gears when it gets used for any period of time, it works fine initially but as it gets warmed up the lowers just dont have any guts and only the higher gears provide any real movement. The repair shops around here tell me that band one is worn out, or not adjusted tight enough, and the adjustment on this one is already tightened all the way in when I first bought the tractor. I bought a spare transmission that was supposed to be good but it's adjustments are the same for the first band, tightened all the way in. I found another one that apparently none of the adjustments are tightened in but I hate to spend more money and would rather use the second one as an experiment first. I really need to spend a day reading over the shop manual and it's procedures for troubleshooting and adjusting and try to wrap my head around it better, it just works differently than im used to on my Jubilee and the other fords ive had.
 
I'd suggest reading the manual as well, because if you had, you would already know that a band 1 failure would make it slip in R2, 3, 4, 7, 8, & 10th gears.

Your symptoms point to more of a band 3 issue if the problem is limited to 4th gear and below.
 
You never mention what model tractor it is for. There were two different S-O-S transmissions for the pre-1965 4 cylinder tractors, (ORC and DDC) plus the S-O-S for the 6000, and then there was the S-O-S for the 3 cylinder 2000/3000/4000 series and a different one for the 5000.

I have a 1959 871.

Actually, Sean, there are 3.
:lol:

The C0NN and C3NN are essentially the same. However, the C3NN has an upgraded input shaft and I'm not sure what else.

No idea would it say it on the transmission case?

Not in so many words. Typically, however, an ORC has the raised numbers 312259 on the left side about where your heel would be were you sitting in the seat.

And normally a C0NN-7006-B or a C3NN-7006-B in the same location is a DDC transmission.
 

It does have 312259 AD CWC #### right beside the clutch pedal. I believe it's a gold demonstrator since the whole tractor is gold underneath red paint, but ive never checked the serial numbers.
 
If it's a "gold demonstrator" it's an early ORC version unless it's been updated.

Any free-wheeling gears?

That's very likely the original then, and is the ORC version. It's not a video, but here's a link to the original Ford OEM shop manual that covers that transmission: 1955 -1960 Ford Tractor Shop Manual This also covers most of the Ford tractors through 1964. If you had happened to have the DDC transmission, you would have also needed the SOS supplement manual: SOS Supplement
