That's not the serial number. That is the IH part number. Do you have the service manual for your model year of Scout? The line setting ticket doesn't have a any numbers pertaining to the transmission? Are you embarking on a concours-style restoration where every single bolt must be original equipment?

I will have to dig up my line setting ticket. I have one but can't find it right now. I thought I read that it was the serial number. I am not doing an original restoration, I just thought it was the original transmission. Thank you for your quick response.

Hello fellow IH'ers, I have been gone awhile my 74 sii has been running so well I have not had to work on it for a while. Well as with all IH's the time has come; I have a tranny leak, 99% sure it is coming from the shifter shaft. I know no big deal but I replaced it and I still have a leak. I still think it is from the shifter shaft but the shaft must be worn or has a nick in it.
So my thoughts are to replace the shaft with one out of my spare 727. But having never had the vb out my question is what bolts do I have to take out? I thinking the hex head bolts are the one holding the vb in. What do I need to worry about? Springs, balls or anything else. Plus can I remove the shifter shaft from the vb or should I swap the whole vb? Condition of my spare tranny is unknown, it should be in good shape but it has been sitting for a few years.
Any advice would be appreciated!
Thanks

Yes just the hex head bolts, about 10 of them.
Now a few other things have to be removed first.
I suspect you have a manual. At least all the balls are inside the vb.

Don't forget to snap a few pics before and during

Thanks Craig, I have an IH manual, just have never removed a vb before and heard horror stories of springs flying everywhere.
I have read this post cover to cover and recall mm saying he wire (nylon) tied something together but now I cant find what he was referring to. I have a little time because I have to order a few parts before I start.
Thanks
ron

It could be just the shift seal. Don't forget to remove the kick down lever and shift lever before trying to remove the vb. (it won't come out unless you do)

Hey ron! Ain't heard from ya in coon's age. Don't forget, there are two seals responsible for holding back fluid in that region. The metal clad shaft seal is the obvious one, but many folks forget about the smaller, o-ring type seal that actually rides inside the upper portion of the shaft. A failure at either point could cause red juice to spew out. The most difficult thing I've encountered with vb r & r is dealing with the park pawl rod. Do you pull the circlip to separate it from the vb (tedious as hell and easy to lose) or do you tug it out with the vb? I prefer option b, but care must be taken when jerking on that rod that you don't damage the rooster comb insulator or twist it in such away that the comb detent ball and spring can fly out of there at near sonic speed. Getting that pawl rod back in place can be an exercise in patience too. I've found that it helps to rock the driveline back and forth a little to help free up the ratchet action.
Once you get it all out, take a real close look at your shift shaft seal surface in good lighting. Run your fingernail across it to see if you detect any ridges. That surface should be perfectly smooth. Its just like any critical surface where a rubber seal rides. If there is a groove present, the new seal will get eaten up in short order and the leak that you thought you just fixed will come back again. If there is a ridge, you can take some fine emery cloth and machine the ridge out without removing too much material. That will somewhat renew your seal surface and keep the new seal happy longer.
As far as mixing and matching vb's goes, I'd approach that with caution. For one your donor vb May look like a famblee uh chupeekabruz has been breedin' up in there, meaning it should be torn apart and thoroughly cleaned before placed into service. Secondly, there were changes to the vb over the course of sii production run that don't always lend themselves well to mixing and matching, unless you also mix and match the other associated parts. I'm primarily referring to part throttle versus full throttle kickdown. If your donor is from and earlier sii like your dd is, than it probably wouldn't be an issue. Just something to be aware of. Bottom line, the thing is shifting fine. You're better off sticking with the one that brung ya to the dance for as long as you can. Don't throw the baby out with the bathwater. How many more corny ass sayings shall I toss your way, or did that pretty much cover it?

Hey scoutboy74, your right long time! In this process I actually found an earlier post when I got this tranny that I am thinking of pulling the vb from. According to what I was told when I bought it only has 2000 miles on a "fresh" overhaul. So now I am thinking about a complete tranny swap, although as we all get older I am not looking forward to pulling and reinstalling a tranny. That's work at my age lol.
I am a little confused when you mentioned the smaller seal, is that in the top of the shifter shaft and seals around the kickdown shaft?
Any way I have some options to consider, I don't really want to part out a good tranny, plus I do have a brand new tranny jack that I have never used. Decisions, decisions!
Thank scoutboy74

She ran when I parked it (fifteen years ago). Hopefully its as you were told. You'd be in tall cotton then. You're right on that seal. It is roughly the diameter of a dime and it is the throttle valve shaft seal. All rubber. No metal. They're a little more difficult to source than the shift shaft seal.

Well I just thought I would complete this tranny leak with an update, I replaced the shifter seal and throttle shaft seal and still leaked after I let it sit a day or two. So I swapped out the tranny with the one I had on the shelf took about 12 hours by myself but I am glad to say the "new" tranny works great and the hf tranny jack was a god's send.
Anyway my 74 is back on the road!!
Thanks
ron

12 hours pretty good time. I know it took 4 hours to get mine out and a few more than that to put it back in. Decided to change the rear main seal, while I was right there. Andy helped me rebuild the tranny, well ok I helped andy
