Hot Rods I need a slip yoke...and some advice.

Yeah, that wouldn't cost much, would it?

 

They are right down the road from me, and they ****. They are terrible, lots of complaints and they can not keep employees there to save their lives.

 

I wouldn’t even know how to tell anyone what I need. Three different pros have already told me that the first one I tried with the 1.113” spline OD should have worked. I don’t know if it’s a spline distance or shape issue.
Would I use modeling clay to do an impression of my output shaft???

And even them, do I have them make 2 in case I ever need another one?

or do I try to get this output shaft out to replace it with one that’s common, like someone mentioned above that Moser can do?

 

That’s too bad. I’ve ordered a couple things from them and I personally haven’t had any complaints…yet.

Mustangs unlimited used to be local and they were helpful but they’re not here anywhere. Not too many speed shops here.

 

I remember them from when I lived in CT, and they were tiny.

 

I'll look, but I probably recycled all of them.

 

Maybe more information is needed to help.
What exactly about this last yoke is that doesn't fit? Or the other yokes for that matter.
Is the yoke too big to p*** thru the seal?
If the yoke is 1.5 inches, is the bushing in the tail shaft housing 1.5 inches or 1.375 (1 3/8) inches.
If the tail shaft housing and bushing were out of the way would the yoke fit on the splined output shaft?
The spline, the bushing and the seal all have to fit. At this point knowing exactly which part(s) of the puzzle don't fit will go a long way toward solving this. Some dis***embly may be required to find these answers.

 

I was being cynical. Having someone make a slip yoke would be prohibitively expensive.

 

This has been going for awhile, so I can't remember all that has been done.
If it were me, the first thing I would do is take the transmision to my local drive shaft repair shop. They know EVERYTHING about driveline components.

 

Except for the OD of the yoke being 1.5, does it fit the splines a little before it hits the seal? If so, worse case you could machine the yoke down to 1.375 OD?

 

I have a yoke with 25 spline and 1.375 OD. Small u joint, alla 65 Comet stock 3spd [Really small], or Dagenham 4spd. Not usable as od is worn but you can have for test fit. PM me a phone # and I can send you a pic.

 

The splines do not match up on the first two...this latest one (with the 1.5" shaft) won't clear the seal that they installed when they refurbished the transmission. I am tempted to pull it out and see if these splines work, but I want to wait until I KNOW that I have another seal that's this size. For all the BS I've been going through, this MAY be the last seal in the world that fits.

I've been working with mine and they do not. 10 months ago there was a different guy there who moved to a different office on the other side of the state...maybe I'll call him up. ALL of the places I've spoken with sigh when I say 25 spline. I asked my local guy if I could bring it in and he said that he didn't have any 25 spline units to try. I have another thread going about CT Transmission Shops to try so maybe on Tuesday I'll trek this ****** around and see if I can find it.

I figure it would be...but I'd be interested to know. I want to get all the parts together so I can make this swap over the winter. I just want the damn thing, at this point.

 

Someone on the AMC forum posted this...these numbers didn't come up on Google but figured someone here (or in the future) might be able to make sense of them...

"The parts book shows 3 different part #'s for the yoke used with the OD transmission. All are group 9.104-1.

3225388
3225420
8127039"

 

Record the part number on the seal and post it.

See if the yoke fits without it. If it does, put the calipers on the seal surface of the yoke and post that.

The power of the HAMB will find you the part number of a seal that will fit.

 

Any chance there's one thick or missing spline making the two only fit in one orientation?

 

Quite possible.

 

I ran a triangular needle file along each spline just in case but that didn't help much. I thought about that, though.

The seal that is installed in MY trans has no visible part number on it. The only "part number" is what Anthony posted above that is installed in HIS trans, but that number is meaningless according to NAPA, O'Reilly's, and that sealfinder site I posted earlier here. It comes back as being 2.25" diameter...the outside diameter of the seal we need is in the 1.95" neighborhood.

 

I’ve got the same OD. Here is the seal # on mine.
Nothing I googled matched it

The British sites listed seals for the OD but I haven’t seen a measurement for one yet

 

I have a dial caliper and, with the seal in place, got somewhere around 1.94"...
I purchased 2 today- one is supposed to be 1.938 OD, the other (picking up tomorrow) is supposed to be 1.955. Both have an ID of 1.375".

I also had to order one from Amazon that's 1.938" OD with an ID of 1.5"... Might take a week and a half to get here, though.

Thanks for all the help EVERYONE. I do appreciate it.

 

OEM seal.

That's all that is in the cross reference.

 

https://www.timken.com/wp-content/uploads/2020/02/National-Indust-Seals-Catalog_7707.pdf

Start on page 12 for 1.375" yoke size.

Start on page 16 for a 1.50" yoke size.

 

Thanks Gimpy...
That's what's so strange about Anthony's part number...all of the cross-references show what you posted, but our measurements are 1.375" for the shaft and 1.9**" on the bore....22430 is 2.25" and 3.25", respectively.
Crazy...I know. That's what's making this search so frustrating.

 

I found this to be a good site...this is what I used to get the ones I just ordered.

Well...I'm still defeated. I worked on finding this damn thing for 7 hours today and I am only MARGINALLY further along in that a couple of AMC Parts suppliers think they may have one deep in the back of a warehouse or in a field somewhere.
It's crazy to me that I've talked to about 20 people on this EVERYONE sees the measurements on the first yoke that I purchased and says, "this should be it." Just in case the wrong yoke was in the box that I was sent, I ordered another one today from a different supplier. I'm not hopeful.

There is a local speed merchant who's business has been around since the 50s and he had a stash of used yokes and was kind enough to bring them down to my car (transmission in trunk) and try out what might fit. The only one that REMOTELY fit was 25/26 (a 26 spline yoke with one tooth missing making 25 little points)...only thing is that my output shaft is 25 splines. I even counted 3 more times to be sure. He sent me to a driveshaft place about 30 mins away that I was hopeful would have some that I could try, but they did not....they told me...to try that same part number that I tried at first...

I tried a small engine shop whose owner I know has one of these set up for a Triumph- so it has the flange style output shaft and he had me unbolt his flange to see if the splines looked similar...I was so excited that it didn't even occur to me that my output shaft isn't threaded, so it wouldn't have worked for me anyway.

I tried three transmission places today and one sent me to a driveline place who also recommended... the same part I tried already...then told me about 2 other transmission shops. I called them and one guy said he'd look and the other said that he didn't have any slip yokes on site.

I've called so damn many people that I can't even remember who told me what. I'm pretty much burnt out on this search...

If these AMC guys don't pan out, I'm half thinking of calling up Gear Vendors and seeing if the tailshafts and housings they use would bolt up to this and if I could just buy one of those. Supposed to be a common TH400 spline, from what I hear. Also thought about going back to the guy that rebuilt this (he had it for 8 months last time and was DIFFICULT to get in touch with...I lost touch with him for 6 months) to see if he could put in a British flange style output shaft and then use a slip-shaft...apparently all of these driveshaft places can make it.
Other option was the one here who recommended getting in touch with Moser and sending them the most likely yoke and the output shaft and have them cut the shaft to fit...

It's just crazy to me that the consensus is that this is a mid60s Falcon or Mustang and nothing is working.
One guy from the AMC Forum said he thought he used one off a T5 but those don't seem to be 25 splines.

Thanks for all of your suggestions thus far.

 

The T10 in a 63 Ranchero had a 25 spline count shaft. They were considered weak and frequently swapped for the more popular and stronger 28 spline shaft.

 

snoc653...I THINK I have that one now...it's 1.5" seal/shaft diameter. My thought was to pull out the seal and see if the splines fit...the one I have is the type that the splines are deep inside the hole. I just want to be sure I have the right seal to replace the one I have to yank out, first!
Thanks.

 

did you try Todd at Fleet Pride in waterbury? He has been really good with the stuff I needed for driveshafts

 

I tried FleetPride last year and was told that they're out of the driveshaft business, sadly.

I may have had some headway today. One of the AMC Parts Houses (Blaser's) did a deep dive into their stash and found one that they guaranteed would fit- NOS in box. It was considerably more money than the others but, as they say, I'd rather be looking AT it than FOR it.

There's also a place called AMC Acres that was very helpful and is still looking. with this being such a pain to find, it wouldn't kill me to have a second one hanging around. A guy from Dayton Clutch and Joint is also trying to locate something. He was so interested in solving the search that when I called him to tell him that I MAY have it on the way already and not to waste his time, he asked me to send him measurements when I get it so he can see if he has a solution on his end that wouldn't require posterity needing an NOS part.

I will post back with results.

Thanks to all.

 

Man, I appreciate the drive you have looking for this yoke!
I would have went with a different transmission already!
My luck would be I would have found the only yoke in the world that would fit, then on the 1st burnout it would self destruct.
I much prefer to build my stuff with lots of replacement parts when ever possible.

 

Yeah- I have the same luck. The problem is that this seemed like the easy option from the get go- fits exactly where my current ****** is and uses the same shifter. No cutting new holes or running linkages to a more rearward mounted shifter…
Then I added up how much money I have into it…. I just want it to work.
