ok, i got the 944 CV's off the shaft ...

i wanted to know if the wear was too bad so i took them apart.
looking good! almost no wear (came off a 944 turbo) ...

i cleaned them up thoroughly as i was told not to mix different kinds of CV grease and now the question is:

how do i pack them with new grease?
grease the parts first, then try to assemble or assemble dry and then pack the whole thing?

Well, I agree put them together dry and then pack the heck out of them.

By the way they are a real trick to get together. If you have never done it you will "invent" a couple dozen new curs words. Please let us know what they are.

I did a few, and then learned that my son could do it, must be like a rubic cube that I could never get either.

So I whine at Johnman and he does all of them now.

Yes, dont force anything when putting them back together.. when you get it right it falls in place like solving a rubics cube...

then get yourself a handful of grease and start working it into the joint... you kind of want to scrape the grease away from your hand while packing the joint.

Its FUN (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)

So Andy,

Why are you doing this? Were your old CV's cr@p or is there some kind of upgrade going on here?

Always curious,

Jon

no problem there, i'm still able to solve the cube, in my hayday (20 years ago) my times were between 30 and 40 sec. for the entire cube.

nowadays it's around a minute ...

both ...

i have had one bad axle ever since i got the car. lots-a-play. clonk clonk clonk ...
that, and my desire to have *real* 5 lug in the rear and not just redrilled hubs and the fact the bradhole lost my 914-6 stubaxles made me look for alternatives.

i used clay's shopping list and assembeled all parts needed (from tranny to wheel)

- late '70s 911 drive flange that will fit the 901 but have the larger 6-bolt 911 flange
- 944 turbo CV, will fit the flange
- 914 axle, will fit the CV
- 944 turbo CV, will fit the axle
- 944 turbo stub axle, will fit the CV
- early 911 hubs (pre ~'73) fit the 914 wheel bearing and will fit the stub axle

this will give you *real* 5-lug at the hub as well as bigger/stronger CVs and the assembly has the correct length (unlike early 911 axels) ...

NOTE: in my search for parts, i came across a set of 914 axles that had a different spline!
john at EASY wasn't sure if they were aftermarket or 914-6, but the standard 914-4 axle has 32 splines (so has the 944 turbo) and said pair had only 24 splines and thus didn't fit.
so watch out for the correct splines (count 'em)

Looks good Andy, good to see you got the seal boot off. Once you figure it out, it all makes sense and one of those oHHHH, that make sense moments come. How hard was it to find the part for the conversion and did you buy anything new?

In general, it's not a good idea to take these apart and then put them back together unless you kept track of what ball went in which hole. The balls and races wear together as a set. When you mix them up, it can cause accelerated wear problems. Very similar to gear sets in the transmission that you wouldn't want to mix and match once they have been 'run-in' together.

In many cases it will be fine, but just as a general rule it's better to keep the balls in their orginal races.

How do you clean them then? Just clean it with it together and repack? Pretty hard to label the balls. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

I've assembled the same parts. Paid $65 for the output flanges, $50 for two 951 axles with good CV's and boots. and $35 for the 951 stubs. That's a lot more than just drilling the 4 lug hubs, but I want those big CV's. That way I can break the transmission instead of just some lousy 914 CV's.

How does the strength compare to the 911 shaft/cv with spacers route? (that's what I have)

i don't have the prices yet as john at EASY let me take all the parts i had on the list and make sure it all fits before he charges me. i'll know the exact prices by next week ...


QUOTE
What did you use to clean them with.


screwdriver, rag and brake cleaner.
i used a screw driver to remove the big chuncks of grease. then used a shop rag to remove most of the rest, then sprayed it down with brake cleaner and wiped off the rest ...


QUOTE
How hard was it to find the part for the conversion and did you buy anything new?


no new parts, all used. the 944 turbo axles and stub axle are PLENTY and easy to get. so were the early 911 hubs.
the later 911 tranny output flange was a bit harder to find, EASY only had one set.
i also got two 914/4 axles to take the shafts from, but he's got 100s of those ...


QUOTE

agreed! but the 944 CVs i got have virtually no wear on them, so i'm hoping it'll be fine ...


QUOTE

should be about the same. from comparing the two, the CVs look very similar in size.


(IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) Andy

PS: actually, i lied about the "no new parts" ...
i'm going to use NEW gaskets on the 911 tranny output flanges where they meet the 944 CV!
the 944 CVs itself doesn't use a gasket, but when you mate it to the 911 flange, you'll need one. standard 911 output flange gasket.

You don't have to label the balls themselves, just put them in a numbered container (like an egg carton that you have numbered).
The housing is easy to label or just mark in one place and use a numbering scheme that you can remember.
