I'd like to know if a CV joint exists that is;

100mm outside diameter,
86mm bolt circle,
and 28 spline (would fit 930 axle)



If that doesn't exist, how about this;
108mm outside diameter,
94mm bolt circle
and 33 spline

Actual Porsche (or other manufacturer) part numbers would be a god sent.

Sure... that's what I used in my conversion thread in the Classics.

Thanks Erik. I saw that string when you first wrote it and then couldn't find it again.


Other than just refering to the CV as from an "early 911", could you give a specific year. (as you know, I'm new to this Porsche stuff)

(oops, missed the pre-74 comment)

Were all of the early 911 CV's 4 bolt and 2 pins or were some of them 6 bolt? The flange (at the wheel) that I have is for 6 bolts.

The output flanges I just got are six bolt 100mm. They are off a 76-79 915 tranny.

76 on up went 6 I believe. I'm no ex-spurt though.

The ones I used looked to be 70/71ish.

This is the list Andy made for using the 944 CVs on 914 shafts with 911 hubs.

BFH
two new 914 rear wheel bearings
four new 944 100mm 6-bolt CV joints including mounting bolts, boots and grease
two 911 ('75 - '79) 100mm 6-bolt coarse spline transmission output shafts
two output shaft seals
two 911 ('75 - '79) 100mm 6-bolt stub axles
four 911 100mm CV gaskets
two 911 ('69 - '73?) hubs, must have same bearing surface width as the 914 hubs
access to a lathe

I think the 944 CV's are normally 33 spline. What's not noted in Andy's list is if the axles are 33 or 28 spline. It's possible that some of the turbo 944's are 28. I don't know!

In Erik's write-up, he is specific about the axle that he is using is a 28 spline.

I can get (from Pelican) a complete, new, axle assembly (from Empi) for $69, which would get me the two CV's I need, but they list it as for a 1965-68 911. That's "pre 74", but I don't feel comfortable that the CV's are 28 spline.

All of this is an issue due to the fact that I'm going to use an Audi 012 transmission. At the transmission, a 930 CV can be used (same bolt pattern and size). The 930 CV is 28 spline and that dictates wanting a 28 spline CV at the wheel hub. The 911 wheel axle stub I have wants a 100mm 6 bolt CV.

Wes I'm sorta new to the 911 stuff also. I think vw bus, and thing is also 100mm cv. Check out www.blindchickenracing.com, cv joints 101, I think I found this on samba a coupla years ago. It seems the jist of cv's is that 930 may have the most articulation but it's also 108mm and as you said 28 spline. You will need a 108 axle stub or a axle with both spline counts on each end it seems. There's a site on cv's and alxe measuring that might be of help. It also discusses keeping the rotation the same when installing and removing axles.http://www.rorty-design.com/content/axles.htm

I've got that "CV-101" page in my favorites. He gives pretty much all the dimensions for the common CV's out there, but never comments on spline count. I looked all over that web site looking.

Getting axles of the correct length isn't a problem (as Erik has pointed out). Sway-Away has them pretty much in 1" increments. The selection of 28 spline axles is greater than the 33 spline ones.

Empi also sells axles in various lengths.

(Sway-away is willing to build up axles that are 33 on one side, and 28 on the other, but the cost is high.)

I wonder if the swayaway cost is more than a 944 108 stub axle? I'm sure the 108 is a tight squeeze on your rear arms also.

Something I forgot about is I bought some parts on samba and when they came the axle stub is a stub cv combo, it's a 993 part and I didn't notice the stub didn't have the six holes in it when I bought it. It might be a way to stay with 100mm cv's and still use 28 splines axles. I didn't get the inner cv hub to see what splines it is. Also the boot must go over the outher OD of the stub cv so it might be just as big on OD as a 108mm cv.

And are 33 spline (which is what the 914/4 axle is.

Does anybody know the dimensions and spline count for the 84/86 911 carrera CV? (porsche number 923 332 032 00)

The PET (factory diagram and parts listing) shows that in 84 and 86 there were two different CV's. One is the 930 (turbo) version (930 332 034 00) and the other is the above noted "carrera" CV. The 930 CV is 108mm, 28 spline, 6 bolt.

Both call out for the usage of 6 bolts (and no dowel pin shown in the diagram)

From what I can tell, all 911's had 28 spline axles.

So ---- maybe that carrera CV is the magical 100mm, 28 spline, 6 bolt CV I want.

I don't know why the 76 to 79 911 wouldn't be what you are looking for. This is where the 6- bolt output flanges comes from. Should be 28 sline or I imagine Andy would have used these instead of the 944 CVs.

All the 911 stuff was 28 spline cause it's better (IMG:style_emoticons/default/hide.gif) (IMG:style_emoticons/default/biggrin.gif)

You boys be making this way more difficult than need be:

Find macthing 911 stub axles and flanges, get the CV's and some Empi or Sway-a-Way axles and bolt it up. Done.

You can use the 100 or 108mm CV's, it all depends on the flanges and stub axles you've got. I can't imagine why a 2000lb car would ever need anything more than the 100's but, nothing wrong with a bigger net.
