Those CV's are still smaller than the early 911 CV's


Ok. I dont remember how much the splined center of 911/T2 CV was wider than 914 CV, but the difference is not big compared to 944 CVs (4 mm). So, this same concepts works with 911/T2 CVs too, right ??

with a V8 teener, you *WILL* break the 901 anyways, just a matter of time ...


If we could have and drive legally V8 teeners here, I am sure I would build one. Then I would consider very carefully using Renault UN1 transmission. They sell conversion bellhousings for SBCs, SBFs and Buick/Rover V8s. The tranny can handle 400 bhp. LINK

on race-cars.com there was on of these Renault gear boxes for sale, 1500(US)....bad part was it's in Europe...

No, they have the same diameter and number of splines. Like I told before I have done this same conversion with 911/type2 CVs.

Early 911 ('69 axles are the ones I just counted) have 28 splines.

What are the relative lengths of 914/911/944 axles? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
I am trying to identify the ones I bought as a 911 CV & axle set with trailing arms that were mounted on a 914...

The 914-6 axle shafts (or at least that is what they sold them as) are the proper length for 914's and do have 28 splines, and will (with similar machining) will accept 911 CV Joints. I just tried this myself and they will fit if the shoulder on the 914-6 axle shaft is turned down just as is done to a 914-4 axle to accept the 944 CV.

But the problem with using 914/6 axle shafts is that they are fairly rare. With the 914/6 stub axles there are repros being made. The six axle shafts are not being made in repro.

The whole reason for this elaborate setup is to be able to use stock 4 cylinder shafts and relatively low cost 944 parts to get a CV setup that is stronger than stock and doesn't use a redrilled hub.

I didn't know the 914-6 axle shafts were that rare. I know 914-4 axle shafts are more plentiful, but as far as I know you can still buy complete 914-6 axle shafts complete (with CV Joints).

So........

911 (pre 1985) fit the 914-6 axle shafts (same splines) axle shafts must be machined for wider CV joints
944 (pre 1986.5) fit the 914-4 axle shafts (same splines) axle shafts must be machined for wider CV joints

Both of these solutions utilize 100mm CV joints with (6) M8x1.25 bolts.

With each of these solutions, one could use 911 rear hubs with either 944 (pre 1986.5) or 911 (pre 1985) stub axles with (6) M8x1.25 bolts.

TimO,

I may be asking you about how you will adapt CV's if I get one. Prices are reasonable but shipping to US is high. What clutch and flywheel will you use?

They sell adapters in UK for normal CVs. They are not cheap and I will check if I can machine them cheaper here.

Clutch and flywheel ?? I don´t know. First I have to find a way to bolt it behind my engine. The bellhousing is problem number one first. I have SC clutch and flywheel and I have my conversion flywheel and old 911 clutch. I hope I can use one of them. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

Sorry to hear that the shipping is so expencive...... (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

Hey guys, what is it that Pelican is using here...

(IMG:http://www.pelicanparts.com/catalog/images/Racing/914_Axel_Upgrade.jpg)

http://www.pelicanparts.com/catalog/shopca..._SUSaxl_pg1.htm

Are they having the axles reproduced, hence the high cost? I can't tell what parts they are using based on the pic, but it doesn't look like the stock /4 axle to me. I could easily do this conversion cheaper than what the cost of those axles are.

Those are either bus axles or 911 axles with adapters.

Well I let the Renault slip away at $745 I just couldn't justify paying another $600 to have it shipped here. The good thing is it had the cable shifter included. I will regret it if it had the Derek Bell conversion but the owner was unsure...

Had to resurrect SirAndy's classic thread on 944 turbo CV joints.

Just a heads up.

I'm not sure that it was mentioned anywhere, but here is one thing to check before you get back out there with your car.

Be sure to measure the distance between the new 944 (much wider) CV joint and the back of the out put shaft. The output shaft is the one that bolts to the transmission.

You want the 8mm (1.25) bolts to go all the way through the output flange and come out on the other side. Probably 8-10mm.

I wasn't thinking when I put mine back in and used the 45mm bolts that were previously holding on the 914 CV. Well they are short and you will end up stripping the flange when you torque them in, i.e., they are not engaging all the thread.

So make sure you have about 8-10mm showing out the back of the flange when the bolts are installed through the 944 CV's.

Also make sure you are using the 12 (whatever) grade bolts.

These flanges aren't cheap, so best to do it right the first time. (IMG:style_emoticons/default/dry.gif)

Another trick is to buy nylocks and put them on the backs. I was told racers do this all the time. I did it to one side that was having issues with backing out and it worked perfectly (IMG:style_emoticons/default/beerchug.gif)

And they're really hard to find. A few years only before the spline count changed.
