-hint... WHERE IS THE CAR!?-
Posted by: SirAndy Aug 7 2005, 08:55 PM
you know how it is ...
since i powdercoated the suspension yellow, i can't keep up with the car anymore ...
it's simply too fast ...
this was just a test run, making sure all the parts fit together OK. which they do.
look out for my next "how to" on installing the rear mueller roller bearings and the 911 e-brake setup.
once those are done, the new axles will be installed. i promise ...

Yo dog,
aren't you missing the keeper thing that fits in the groove at the end of the CV and presses against the CV in pic #1? What holds the tranny side CV fast to the axle?
Posted by: 914MF Aug 7 2005, 09:11 PM
Is there a reason you did not use the 944 axles? Were they too long? Nice pictures 
Posted by: SirAndy Aug 7 2005, 09:13 PM
wassup bro ...
as i said in the post above, this is just a test fitting. no need to put all those little clips on there just yet.
also, you might notice that the CVs are still missing the grease ...
Andy
Posted by: SirAndy Aug 7 2005, 09:14 PM
yes, 944 axle is ~1" too long ...
see this thread for more details:

Nice Sir Andy! WTG! 
Posted by: rick 918-S Aug 7 2005, 09:29 PM
Anyone have a part cost breakdown? What do the early flanges go for used? Can you use non-turbo 944 stuff? ie, axle flange, CV's, etc.....?
Posted by: Dr Evil Aug 7 2005, 09:46 PM
He he, word player. I noticed Mikey's lathing to fix the prob too. Thanks for putting all of this stuff up for everyone. Someday I wanna do this conversion. I wish that I would not have sold my early 911 hubs 
Posted by: Engman Aug 7 2005, 10:16 PM
At least now we have a solution to the NLA cv joints on the 914.
Nice work guys!
Now pics in the car!

what bearing will you use?
Posted by: SirAndy Aug 7 2005, 11:26 PM
i've got the stock (FAG) 914/4 wheel bearings ...
the early 911 hubs have the same dia. as the 914/4 hubs and will slide right into a stock 914/4 bearing ...

sweet!!!
Posted by: SirAndy Aug 7 2005, 11:33 PM
not yet as i haven't paid for any of the stuff yet ...
Mr. EASY let me borrow all the parts to make sure it would all work together before he was going to charge me ...
hmmm, i think i'll drop by there tomorrow with a sixpack of beer for the guys,
now that i think about it, that was awfully nice of them!

hey,
whats wrong with your camera?
Those pic´s are so ...hmmm...clear! 
Posted by: John Jentz Aug 8 2005, 03:36 PM
Andy, what is the diameter of the C/V's? 100mm or 108mm?
Answered my own question. 100mm from Part II!

Good job Andy!
Two questions come to mind;
1st- Is the 944 stub & 914 stub axle the same overal lenght?
2nd- Does the 944 Cv have the same articulation as the 914 CV.
Cheers
Stephane

these 944 axles are too long...see this thread for more info...
http://www.914world.com/bbs2/index.php?act=ST&f=2&t=36170
the 914 axle must be machined a little to work with the 944 CV
Posted by: SirAndy Aug 8 2005, 05:54 PM
yes, but he asked about the "stub" axle ...
the 944 Stub Axle is the same width as the 914 stub axle on the CV side of the wheel-bearing, the only difference is that the actual thread that sticks out on the wheel side (outside) seems to be a bit longer ...
AndyPS: i don't have a 914 stubby handy, but i can take exact measurements once i get back to EASY ...

if by that you mean the degree of rotation, yes, the two CVs are completely identical, except the 944 CV is bigger ...

That's great, this sounds like a more affordable way to convert to 5 lug & I bet these parts are easier to find to.
Keep us posted please!
Stephane
Posted by: cha914 Aug 8 2005, 06:27 PM
actually I think the 944 CV's will give you more articulation, if I remember correctly from my dune buggy research, the bug CV's are the worst (probably pretty close to the 914's), then the 944 and TIV bus CVs are next, and then the 930 CV's give the best articulation and will handle the most power...
here is a good site with the different sizes:

hi Andy,
thats a really nice work !!!
I've had the same idea to convert the rear to five lug using 944 parts . But i'm still looking for the right cvs.
http://www.914world.com/bbs2/index.php?act=ST&f=2&t=10653&hl=sechszylinder
Whats the partnumber of the 944 stub axles your using ? Mine came of a 944 turbo and have the part # 951.332.235.01.
They fit right into the ealy 911 hubs, but they are a little bit longer than the original 911 stubs ( approx. 1/2 ") .
greetings from Berlin

Posted by: SirAndy Aug 12 2005, 02:02 PM
ok, just got back from EASY with some more info ...
1 - yes, same part number on the 944 stubbies. they fit just fine.
2 - the CVs don't have to be from a 944 turbo, ALL 944s with aluminum trailing arms have the same halfshaft and CVs, however there are 3 different types of stub axles and hubs on those (later) 944s.
3 - the donor 944 needs to be post-mid-85
4 - Price: used 944 turbo axle (including the stub axle) ~$100 per axle (*)
5 - Price: used coarse spline 915 output flange ~$75 per flange (*)
Andy* prices may very depending on your haggling skills.
you can increase your haggling skills using manna from slashed goblins.

will 944 AUTOMATIC CV's and Stubs work?
Posted by: ClayPerrine Aug 12 2005, 02:32 PM
IIRC.. the stubs are the same. But I think that the axles are different for an Auto.
But I have been known to be wrong.
BTW... I beat everyone here to it. I have this setup on my car right now. I have driven it and it works fine.
Posted by: SirAndy Aug 12 2005, 02:45 PM
Posted by: Aaron Cox Aug 12 2005, 02:49 PM
clay -
the AUTOMATIC axles look to have the same CV's and STubs....BUT the axle length is different....
not happy about the price and rareness of the 915 flanges though 
Posted by: SirAndy Aug 12 2005, 02:54 PM
they're actually not *that* rare ...
there were a few years somewhere between '75 and '80 when the 915 used the coarse splined input shafts ...
and the price may very well vary from different vendors, what i listed is what *i* payed ...

Benno, check out the mittelmotor website
they have a special offer on the 944 cv's during their "Sommerfest"
Posted by: sechszylinder Aug 13 2005, 12:51 AM
hey jeroen,
thanx for the hint. A friend of mine will pick up some stuff for me at MM sommerfest ...
Benno
Posted by: sechszylinder Aug 13 2005, 01:12 AM
hi folks,
now i'm comletely confused. 
I've had a look at the parts catalog of mittelmotor (www.mittelmotor.de).
They list only two different cv's for the 944.
1. 82 -89 all 944
2. S2 and Turbo
According to PET there must be at least three different CV's, which means that 82-85 are
different from those used on the later cars.
Could someone bring a little bit light into the darkness ? 
Benno
Posted by: SirAndy Aug 13 2005, 04:17 PM
there's 3 different types of axles for the 944, but only 2 different types of CVs ...
same CV for:
944 '83-'91 and pre '87 944 turbo
different CV for:
944 turbo '87-'91
here's the number off the CVs i have:
C 153120198027 LOBRO 17 91 W-GERMANY

o.k. Andy, now i think i've got it
that means, that you can use any 944 (as well 924S) CV from 83 thru 91 in combination with modified 914 axles and the early turbo stubs.
Later CVs from S2 and Turbos will not work, due to a different splining on the axle side.
o.k. thats it
now i will go out and hunt for parts ;-)

Andy,
Where's part I of this triology?
Nice job, BTW...
Posted by: SirAndy Aug 14 2005, 10:26 PM
somewhere in here, but it has a different title ...
i'll merge all previous threads into a "HOW TO" article once i get the axles installed ...
Andy
Posted by: Gary Aug 16 2005, 10:14 PM
If anyone's looking to do this, there's a pair of 994 stubs on ebay, item 7992744129. Part numbers from the picture match. One more day to the auction. No association with the seller, thought someone might be interested...
