Default Dimensions NEEDED......Front Driveshaft Splines (Torque Tube)

Hey folks......If anyone has a torque tube-type DRIVESHAFT laying around with it's FRONT splines easily accessible, I would sure appreciate a couple of fairly accurate measurements with a caliper. I need the MAJOR diameter across two of the raised splines on shaft, and I need the MINOR diameter......as measured across two opposite, LOW areas BETWEEN the raised splines. As U-joints from '28 thru '48 will all fit, any year V8-type shaft with CLEAN splines will suffice, but the dimensions need to be accurate. I have a U-joint which I've measured, but I need to see what kind of clearances exist between U-joint and the six splines on shaft.

Now, for the interesting part of all this, I'm really trying to figure-out the exact size and nomenclature of the Spicer-type U-joint (pictured below). This is one of CRAZYDADDIO's (from the HAMB) torque tube adapter kits from the past. He no longer makes these kits!

Anyone familiar-enough with Spicer stuff that can head me in the right direction? I just need to know about the REAR half (rear yoke) on the pictured U-joint that'll fit an old Ford 6-spline driveshaft. Thanks for ANY help. DD

V8coopman- I just measured a NOS driveline with a Browne and Sharpe caliper and best I can tell it is 1.090 across the high and .910 in the low. At least there isn't any wear on this but there is always measurement error!
P.S. not much left of that cross member!

Hey deuce......I can't thank you enough. Your method is exactly what I was looking for with the measurements, but we MAY have a slight problem here. The U-joint we measured is 1.085" inside the major. That looks like about a 0.005" interference fit with your 1.090" spline. It's possible though, that this USED joint was not as clean inside as as it should have been. I'll re-measure!

Your second MINOR dimension of 0.910" sound about perfect for our U-joint which is 0.926".........about 0.007" clearance. Thanks again!

Anyone real knowledgeable about those Spicer-type joints?

By the way, that's not my frame. It belongs to an awol F'Barner by the name of BLOODYJACK.

Yeah, that shouldn't be a press fit! I will go measure it again...
checked 3 place on each spline, all of them are right at 1.090 or 1.091
I don't have another one to measure.

deuce.......I'm sure your dimensions are accurate, and that there is a problem with this joint. More-importantly, you've given me the important dimension that I needed, and off of a pristine, new piece to boot. Very much appreciated! DD

Hey V8Coopman: I think the part numbers that Pete1 references in his T5 with a torque tube post are worth checking out. These part numbers are for a U-joint that has support for a 6-spline Ford driveshaft (he uses a Turbo 400 front slip yoke and some combination of these u-joint numbers to mate to a 6-spline ford drive shaft).

U-joint kit is, Neapco 1-0153
or TRW 20049
or Spicer 5-153X.

DD, Deuce is as you know one sharp cookie. If you desire for any reason, I have drive shafts I can measure as well. I could I suppose pull out a NOS u-joint too.
Let me know and I'll do whatever is needed.

Kube, I should have used a micrometer. I usually use the calipers to COMPARE things and a mic to MEAUSRE things. I know with your background you can get another decimal point accuracy!!

I have a '34 driveline on the shelf it it would help and live in south Houston if you want an actual drive line to check.

At one time I was looking at this stuff for an idea I had.

If I remember right; CRAZYDADDIO said in one of his posts that the rear yoke splines were machined special for him.

I looked up the part numbers listed in Pete's post and while the U-joint numbers are regular 1310 joints; neither of the other numbers correspond to a regular yoke. One is a weld on 32 spline stub shaft and the other the matching slip yoke. I kinda questioned this in the other thread; but had no response.

I'll ping Pete for more info . . .

You're funny! I am certain your numbers are spot on. I know V8Coopman can get a bit obsessive at times. Perhaps more so than me. Yep, another "crazy" out there in Ford Land!
