Inner CV Joint Bearings

[Number1_dog]

I know there has to be a trick to this, but how do I get the bearings and the bearing case back into the bearing housing on a 1979 911SC inner CV Joint?

Let's assume I have all the balls in the same exact place as they were when it was together.




Thanks, dog

It's like a Chinese puzzle and hard to explain but I'll try anyway.

First this take everything apart. Then put the inner and ring inside the CV.
Cock the inner with the ring inside the CV until you can get one ball in...
Then cock the next position and put the next ball in but don't let any fall out as you do.
Keep going until all 6 are back in. It only goes back together one way.
They just snap in...There is no need to use a lot of force so don't be tempted.

You can do it. Play with it until you learn how the inner and ring moves around inside the CV. Just takes a bit of practice.

Well done for having a go.

Thanks, I was thinking that may be the way.

When I took the engine out I put plastic bags around the cv boot and joint to keep them clean, but I never looked in the boot. CV joints were always something of a mystery to me, you just replace them.

2 weeks ago I asked an experienced Acura Mechanic, who is also restoring a 79SC, what is it on the CV joint that I grease? He laughed and said it was just like packing bearings. When I went under the car to look at what it was I had to grease I found the bearing housing cocked with one ball in the bag, so off came the joint

So as it has been for the last year or so, I am learning a lot about my car that you can only lean by doing. Thank god for you guys who have helped the inept newbies like me!!!

Sounds like you're having a lot of fun learning.

Just stay motivated and don't start too many projects at once.
There's nothing like fixing something yourself. Guys who outsource everything don't know what they're missing.

And girls like guys who are handy

Think of all of the money you're saving.

It is not just money I'm saving, but I'd be driving a VW and not a Porsche 911.

It has been a fun experience so far I did a top end rebuild with Max Moritz 98mm (compression up grade from 8.5 to 9.3 to 1) P&C, 964 Cam profile re-grind, lightened flywheel, a set of cast off SSI's with a M&K 2 in 2 out exhaust. My last Christmas present was a set of 46mm PMO's that should be going in this summer.

I have started some repairs on my front fuel tank support, future project is a front suspension pan replacement.

So I've saved some money but have also spent some too, but I am slowly getting together the car of my dreams.

I'm more comfortable around the guys who do stuff than the guys who pay others to do the stuff.

thanks again, dog

I think your trying to put it together wrong. The wide spaced outer matches with the close spaced inner it that helps.

Outer wide surface to narrow inner surface. There is a picture of this in Randy's Reconstructing CV Joints found several pages into this thread.....

Balls can fall out of the cage into the boot if you let the axle hang down

I suggest that you service both CV's (inner and outer) on both axles.
If you find any galling in the races, you can either flip them of get new ones.
Flipping will give each CV a new running surface. Flipping can only be done on SC-axles, not Carrera ones.

Packing the CV's is done with Moly grease and you'll need gaskets to prevent the grease from being thrown out when running. Install Zip ties on the smaller diameter of the boot. Use the correct torque for the M8 Allen bolts.

There was a recent post that shows how to put these CV's back together. And it has pictures too. The above statement by Tim L is the magic trick to get them back together like a puzzle. If you could not visualize what Tim L is saying, I would suggest that you search for the CV installation thread posted not too long ago.

No I see exactly what Tim is saying, and thanks for the picture Tim.
Just looking at my picture I see I have wide and wide and narrow and narrow matched up, or should I say mis-matched up.

Thanks again all, I would have just a jumble of pieces without you!
