601 selector speed

I traded a john deere 950 for a 74 model ford 4000 3 cyl about
four years ago. I like it, good tractor. I traded for a 80 model
3600 a very good tractor. I was a fool and sold my 3600, I still
have my 4000. I got me a 64 model 2000 loader tractor with a
shuttle shift, I like it. I want a ford sos, it does not have to do any
work, but I want the sos to be good. If the sos go out down the
road I can sit and look at it.My question is on a 601 selector
speed, it is a early one. Did all of the early one get the up grade
or fix, or some of them still the bad one ones from the factory? I
grew up on IH, but since I have been playing with these fords, I
like them,easy for a old man to get on and off.Sorry about the
long post, just wanted to talk fords.
 
Hard to follow your sentences:

I traded a john deere 950 for a 74 model ford 4000 3 cyl about
four years ago. I like it, good tractor. I traded for a 80 model
3600 a very good tractor.

The first couple of sentences above led me to believe that you traded the 4000 for the 3600, but then you say:

I was a fool and sold my 3600, I still
have my 4000.


So I conclude that you didn't trade the 4000 for the 3600. Then you say:

I got me a 64 model 2000 loader tractor with a
shuttle shift, I like it. I want a ford sos, it does not have to do any work, but I want the sos to be good. If the sos go out down the road I can sit and look at it.

So what do you mean by "a 64 model 2000 loader tractor with a
shuttle shift"? Is it a Select-O-Speed? Or is it a 4 speed manual with Sherman reverser?

Then you say:

My question is on a 601 selector speed, it is a early one. Did all of the early one get the up grade or fix, or some of them still the bad one ones from the factory?

I assume that you meant Select-O-Speed when you said "selector speed". Ford offered the upgrade from the earlier Over Running Clutch (ORC) Select-O-Speed (S-O-S) transmission to the later Direct Drive Clutch (DDC) S-O-S, but not all of them got the upgrade. The Ford replacement program was because the earlier ORC design allowed the tractor to "freewheel" going down hills, which was a safety concern, not because all of the earlier ORC transmissions were "bad".

The "bad ones from the factory" were not all of the earlier ORC transmissions. The "bad ones" all had problems within the first few years of their lives and have either been rebuilt, replaced or scrapped. Any ORC S-O-S transmissions out there that are still running are not "bad ones", but they still have the potential safety issue with freewheeling down hills.
 
(quoted from post at 17:30:46 07/13/14) Thanks, you answer my question not all of them received the up
grade.

Yes it is possible that here are still some of the early ones out there. If you post the numbers cast in the side someone can tell you which it is. There are also some very distinctive external differences.
 
The earliest SOS transmissions were recalled and updated with some modifications. These modifications did NOT include switching to the DDC. The early SOS housing will have the number 312259 cast into its left side. If it was overhauled/updated by the factory there will be a warranty number hand stamped into the right side of the housing just aft of the engine.
The SOS with the DDC will have a casting number beginning with C0NN or C3NN on the left side of the housing.

Hold your horses there, Texas! Ford had a program in the mid 60s where they replaced some failed ORC transmissions with DDC transmissions. My granddad's 1960 871 got such an upgrade in 1966 for about $600.00 IIRC! Some red tractors had blue transmissions between the red sections. Grandpa was particular enough that he made them repaint his to match the tractor. . . and I believe I would have too.
 
I believe there were two different programs. The earliest ones had a true recall where they had certain things replaced, but they were still ORC models, as the DDC models hadn't come out yet. Then later, after the DDC transmissions were out, they had a program to replace the ORC transmissions with the DDC transmissions.
 
Maybe I should have been more specific. The first recall occured in September 1959, a mere 8 months after the introduction of the SOS. And that recall did NOT include a DDC.
 
Hello Alan , There was also a Ford Bulletin where 312259 Transmissions were drilled out to accept DDC during one of the update programs , no Idea of how many were done but I have seen a few . I also know of guy who still can do it out in Indiana . Thanks Tony
