914/6 axles questions Options

[Project 6]

OK, so I'm ready to install the engine and found a surprise. The PO was going to install a later model trans. As such, they installed 915 style stub axles. The oem stubs are lost in space.

The existing stubs don't bolt up to the 914/4 axles and CVs I was going to use. The 2.0/6 "S" spec motor puts out about 140hp. So I wasn't worried about twisting them with high torque since I used this set up with a 3.0 in the past.

My questions is....are 914/6 AXLES which I might have access to, compatible with 915 sized CVs? FYI 914/6 CVs have been NLA for 20+ years....

Since I have the sub axles, can easily find drive flanges for the trans, I was thinking this would be an easy alternative. Does the 914/6 axle have the same spline count? 28 is what I've been told.

Simply using a 911 axle won't work, too long. Buying 914/6 stub axles is an expensive deal, $5-600. Mittelmotor and Otto....

Some good news, I HAVE been able to locate one stub axle...it will need a little machining as it's a bit corroded. But I'm looking for alternatives.

Anyone BTDT? Or even better....an orphan 914/6 stubbie?

Switch to regular /4 stubs and output flanges and use stock axles with CVs (IMG:style_emoticons/default/smile.gif)

Ok Mike,

I have our axle supervisor looking to see if any of the early 911 CVs we have have the stub axles still attached. Most of the time they are removed.

Will let you know ...........

914-6 axles are splined differently from the 4's, I have both. There are some good threads on this forum about the possible conversions. Look in the Lapuwali Classics section.

I was going to use 930 flanges inboard (930 CV's are easy to find and not terribly expensive) and 911 cv's outboard on the 914-6 axles, but I haven't yet been able to find early 911 flanges either. I thought they would make a good addition to my 3.6L conversion. I have stock 914-6 stub axles already installed.

Although, I've used stock 914-4 axles and cv's with this motor for years without a problem.

After reading the original post a few times trying to understand the issue, it sounds to me like he's already got the 911 stub axles and tranny flanges. The issue is the 911 stubs won't mate to the stock 4-cylinder CVs (true), and the question is, will a 914-6 axle mate to 915 CVs? Right?

I don't know the answer to that question. What I do know is that Sway-a-Way makes the axle you need if the 914-6 axle doesn't pan out. Of course if you can find another 914-6 stub, that's the easiest way to go.

I think this issue gets confusing because different people call the same part by different names. In my mind it's:

tranny <---> flange <---> cv <---> axle <---> cv <---> stub axle <---> hub

no?

For a stock(ish) 2.0L /6, just go back to a /4 setup and sell off your current parts ...

To use a 914/4 stub axle. You need a 914/4 hub. The /4 and /6 hubs are splined different.

Uing a 914/4 hub you'll need to machine and press in studs, you will most likely destroy the bearing.

I'm missing something here guys, how you going to do 5-lug using /4 hubs? I'm assuming that's all part of the equation. Yes it can be done, but that's probably the least ideal approach.

Again..maybe I'm just missing it.

[Project 6]

What I have now.


tranny <---> flange <---> cv <---> axle <---> cv <---> stub axle <---> hub
914/6 <---> /4-/6 <---> /4s <--->/4s <---> /4s <---> late 915 <---> /6
Same thing uses big CVs

/4 CVs and /6 CVs are the same diameter, the axles from the factory have different splines. /6 CVs are NLA. IF the splines on the /6 axle and the 911 axle are the same, I can use them.

The best scenario is finding another /6 stub axle....after going thru Krusty's pile of discards. We found one just hanging about on a file cabinet with three other 914/4 stub axles.

[SirAndy]

how you going to do 5-lug using /4 hubs?

With a tool called a "drill" ... (IMG:style_emoticons/default/shades.gif)

That's your answer to "are 914/6 AXLES which I might have access to, compatible with 915 sized CVs?"...? Switch to 4-lug and drill for 5? Hmm.

Yes. That's my answer. Do you have a better one???

914/6 stuff is mighty expensive. Good luck finding a 914/6 stub axle.

And if i read his post correctly, he has /4 CVs and /4 axle shafts that he's trying to mate to mixed/matched 911 parts.

So yes, my answer still is to go to a /4 setup and sell off the 911 and /6 parts he already has.

At least i'm trying to come up with a solution instead of just talking down people who are trying to help.

"are 914/6 AXLES which I might have access to, compatible with 915 sized CVs?"

That's a question that's still hanging out there. I'm sure there are more than a few original six owners that have old axles with worn out NLA /6 CVs.

What have THEY done? The easy answer is swap in /4 axles and CVs. They bolt right up to the existing /6 flanges and /6 stub axles.

For those with original 6 transmission and rear swing arm assemblies that want a larger CV, the answer would be nice if the could use 915 CVs, which are larger and built to handle more HP. IF the spline count on the /6 axles arre the same as the 911 axles. Again, 911 axles can't be used, too long.

Not MY problem but an interesting question. What's the spline count on a 914/6 original axle???????

[markb]

You're welcome to come up & dig thru our cv's.

[Dr Evil]

Eric Shea sells drilled 5 lug hubs for like $100

[Project 6]

Again, all I'm missing at this point is ONE /6 stub axle.

Swapping the /6 hubs out, destroys the bearings. More money and my labor.

Cheap, easy, no brains, time is my goal here.

The /6 axle issue and bigger CVs is a seperate and distinct issue.

[SirAndy]

Again, all I'm missing at this point is ONE /6 stub axle.

If that's the case, then all you need is $$$ (IMG:style_emoticons/default/biggrin.gif)

[Lavanaut]

Yes. That's my answer. Do you have a better one???

Yes, try to find another 914-6 stub axle if possible, and if that doesn't pan out look into Sway-a-Way axles as an alternative to 914-6. That was in my first post in this thread, maybe you glossed over it. I feel it's a better approach because he can use the beefier parts and doesn't have to use a tool called a "drill" to fundamentally reduce the integrity of his parts.

And hey, sounds like he found a single 914-6 stub axle! If that's the case it's a non-issue in the end. (IMG:style_emoticons/default/cheer.gif)

[SirAndy]

and doesn't have to use a tool called a "drill" to fundamentally reduce the integrity of his parts.

You got any real world data to back up that claim? If so, i'd like to see it ...
