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?
Andy
I assemble them dry and then pack them
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
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

What's your $ for this conversion? If you're willing to share.
use protcorial gloves!!
What did you use to clean them with. I tried blasting my cv's with brake cleaner and the grease just don't budge.
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.

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) |
QUOTE (bondo @ Jul 21 2005, 09:28 AM) |
How do you clean them then? Just clean it with it together and repack? Pretty hard to label the balls. |
im told 915 coarse spline outputshafts are a PITA to find....
everything else is gravy.....
BTW - anyway to drive the 914 stub out and replace it with the 951 part WITHOUT buying new rear bearings???

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. |

Does this mean success will cost a little more? |
Andy, I'll try my best to explain how to re-assemble. put your inner race inside the cage, put two of the bearings in 180 deg. apart. Slide the race/cage and 2 bearing setup inside the outer race holding the two at a 90 deg angle to each other (cage horizontal and the race and bearings vertical) this way the two bearinbgs will easily slide into the two opposite tracks. Once this has been done, add the remaing bearings and rotate the whole assembly 90 deg's. You may have to push a little to get everytjhing to seat but shouldn't have to BEAT it in. Now check for movement. it will be a little akward feeling but should move in all directions. If it binds up really bad look at the inner and outer races, you will notice that the "tooth" pattern is : wide / space for bearing / narrow : the wide and narrow spaces should NOT line up. You need a wide tooth on the inner to match up to a narrow tooth on the outer.. Once packed and boots attached you will notice the assembly is not as loose and should move freely without binding. Hope you could follow my ramblings. It's a PITA no matter how many times you do it. I just did a set on an Audi quattro yesterday, drivers went smooth, passengers

the later 911 tranny output flange was a bit harder to find, EASY only had one set. |

WARNING: LOTS OF PICTURES AHEAD ...
this is fun, just like the rubiks cube!
start by lining up the inner and outer race, just so you remember how to put them together.
see where the grooves on the outer race are closer together in pairs? the larger "nose" on the inner race has to point towards those ...
now slide the inner race into the cage and turn in to line up with the holes in the cage.
add two balls 180 deg. from each other
and slide that into the outer race (lying flat on the bench)
lift up the inner race and cage just enough to add another ball
just do one ball at a time going around
until you got all 6
voila!
moves just the way it's supposed to! but careful, it'll fall apart really easy as well ...
one thing, the 944 CV has a groove on one side which points to the outer side of the CV, away from the axle.
also, the inner race has a flat side and a raised side, the flat side goes towards the outside. not sure if this is important, just something i noticed ...
inner (raised) side of the inner race
now all i need to do is pack it with grease!
Andy
oh, and here is what i started with. took me less than 5 minutes ...

damn, andy -- you could be a hand-model. really. nice hands
Show off. If you hadn't taken so many Andy pictures I would suggest using them for a new Tutorial page.
Nominate this one for clasic thread or how to status
Andy did you paint or Powder coat (yellow ) the shafts?
so does that mean that with these parts,
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
you could frankenstein up real 5 lug hubs on the rear, without messing with the stock trans.????? and without drilling? thats very interesting.
I realize that thoroughness and a quest for quality workmanship would demand changing the trans parts.

Andy,
You don't need the 914 axle shaft. The 944 shaft is the same length.
For those of you who AREN'T cheap, you can buy complete rebuilt axle assemblies for 300.00 a side.
944 turbo CVs are 100 bucks a piece new.
Oh, and the 914 /6 uses a different number of splines on the axle shaft. If you found an axle with one, buy it! It's worth money to any 914 CW who just has to have the absolute right parts.
BTW. .I got all the parts to do my car for under 200.00, including the drive flanges for the transmission.
And Andy, Thanks for the pictures of the CV joint cleaning and reassembly. That is my project for this evening.
Andy:
WOW!, Andy, That is the slickest picture story of a how to on cv joint assembly I have ever seen. Flat on a bench!!, so the balls do not fall out in your lap. I'm going to print out your set of pictures, and then I'm going to try this over the weekend with an old cv joint. I bet even I can do this.
I have always tried it setting down in a chair and at a table, but with the cv joint in my hands and a little clean grease to make the balls sticky, but then there is a solution for every puzzel, we just go through life without the solutions. Too soon old and too late smart as they say.
Is there a similar "solution" to the rubics cube?
Thanks for sharing the solution, and with such a neat set of pictures.

They must have changed the length somewhere in the production run. The axles I have are the same length as a 914 axle.
Good info to know though......

all 944 Cv's are the same though right?
You need the 944 CVs for the aluminum trailing arms. The other ones won't work.

ahndy, what did you use to clean off the grease from the CVs?
Britt:
When i did my CVs, I wiped most grease off with a paper towel, then used brake cleaner, which dries and leaves no residue.
I picked up a set of 915 course spline drive flanges for $80 with shipping.
Post an add on Pelican that's how I got mine. Several people replied so I know some are still out there. I also picked up some 944 axles 6 bolt 100mm cv's
( enroute to me now ) , a set of 911 6 bolt 100mm stubs, and early 911 hubs.
So far spent $365 on parts. When I get the axles in I plan on laying out the 914 parts next to the 911/944 parts to see if theyre the same length. I'll post some pics when I get all the parts on hand.
Neo looks like you are using the 4 bolt flanges?
I picked up some used mid to late 70's 915 drive flanges that have 6 bolts to mount the 100mm cv's ( which is the same as the 944 cv's ), and yes they fit the 901/914 trany. I'll post some pics later when I get the axles in.
OK received the 944 axles today. Looks like the 944 axles are .5'' too long.
I put the 911 6 bolt stubs/drive flanges on the 944 axle and they fit with no problem. I'm not sure if the longer 944 axle is going to be a big problem if I ran them. The alternative is to have my 914 axles modified to fit the 944 cv joints.
My car is in 1000 pieces and have no way to check the fitment of the axles.
I did take some pics of 914 and 911 flanges side by side, 914 & 911 axles, 911 6 bolt stubs and drive flanges.
