I believe the spicer number for the slip yoke is basically for a C-6 part number SP 2-3-6041X. Yoke specs = Seal surface (OD) 1.688 +/- .010, and (ID) low point of spline, not sure what the dims should be I think 1.370?

What are dims of output shaft on the trans? ID (low point of spline) and OD.

31 spline slip yoke will slide on about a 1/2-inch that’s it. I did remove the splined rubber doughnut, which I gave to Homer. I’m miffed course I don’t have all the dimensions needed to make a conclusion unless there is a burr on the output shaft.

Did not notice any whiteness marks on the yokes seal surface after removing. Did try clocking it differently. Double-checked the spline count on the shaft and yoke. I’m miffed again, that's no yoke.

All I had to do, it was such a simple task. :banghead: < and they call him a smiley

I should be the C6 yoke. Did you try contacting your Tremec dealer?

After learning about it tonight I thought I would see if there might have been someone else having had this issue. Funny thing is I contacted the company I purchased the driveshaft assembly from. I asked them if they dimensionally check the yokes before ship, they do not. The only thing this would have told me is that the ID is ok knowing that the OD was properly finished to size from the dims I have.

Really, what does Spicer do, go no go gage. 100% dimensional check every 10, 50 or 100 parts. What is the inspection process even at Tremec? If the tolerance is running high (output shaft) and low (slip yoke) ooooh, I think there’s trouble Lassie.

That’s why I asked. Your right Andrew, could be as simple as contacting my Tremec distributor. I’ll find out tomorrow. Thanks

Seems there is sometimes an issue with some aftermarket yokes running small on the ID major diameter vs. the Spicer or Ford spec yokes.

Fit a Ford C-6 replacement yoke this morning and it fit fine.

I ran into a simular issue with my flywheel. The flange on the crank (ZZ4) was on the large size of the specs and the hole in the flywheel was on the small side of specs. Between the two, it was not going to fit, period. I contacted Centerforce with my demension and they replaced it with one they checked specs on before they shipped it, just to make sure it was going to fit. No problems with the replacement one. Sometimes these ranges in specs just catch up with you. Glad you got yours figured out.

The Spicer part # that I am using is 3-3-2491X. I noticed that in the begining of your post you used a different #. Mine has only been mocked up - not actually used yet, but it did slide right in without any grief.

Because the tech sheet that came with the trans identifies part number 2-3-6041X and no other. Do your splines run all the way out to the end or is there a recess of about a half-inch?

The part# difference is my 1330 series u joint vs your 1350 series u-joint.

So why not go with a 2-3-6041X?

Andrew, that's what I initially asked for when I speced out the driveshaft thinking...that's what I would get and did. They acknowledged that part number as a good Spicer part number. The issue turned out to be the height of the slpine (the ID minor diameter). it was under by .022 yet I had nothing to gage it to since specs call out the ID's major diameter. here in lays the problem with suppliers needing to provide dimensions. The ID major diameter was right but again that's the number they use. The drive shaft company and the trans distributor could not give me the ID minor diameter. I called Spicer's driveline division and now I have a drawing.

The situation has been remedied as the driveshaft peeps had Spicer overnight a yoke to me and, walla...like a glove. 2-3-6041X is what I wanted to stay with and not go to the bigger 1350 series due to clearance to the exhaust pipes (rotating u-joint diameter).

Anything that is tough hopefully nets you learning experience, this will help you to help others.

Glad you got it all worked out. So can you give us a quick summary of what worked?
What is the proper Spicer 1330 yoke part number?
What is the proper Spicer 1350 yoke part number?
What part number did you have and it did not work?

Just info will be great for anyone doing a search later on.

Thanks!

What is the proper Spicer 1330 yoke part number? (2-3-6041X)
What is the proper Spicer 1350 yoke part number? (3-3-2491X)
What part number did you have and it did not work? Was to have been same 1330 yoke part number. Dimensionally it was identical to the Spicer yoke except for the improperly machined minor diameter which was at 1.250 and should have been 1.750. Spicer stamps their name in all their yokes.
