will rear 914 6 hubs work w/ 914 4 axle shafts? Options

[pnewman]

Sorry for the newbie question. I am looking at putting a pair of 914 6 rear swing arms on my 914 4 lugger to do the 5 lug conversion thing and was concerned about the 4 bolt axle shafts fitting through the hubs.

I am sure this is a no brainer for you guys.

thanks, Pete

[Mueller]

nope....different spline count, one has 27 and the other 28(???)

[Aaron Cox]

agree with der mueller meister.....

id be interested in your rear hubs, should you sell them...

[SirAndy]

aehem .... (cough, cough) ...

if he got the 914-6 stub axles, those will fit the 914-4 CVs, so, yes, he can keep the /4 axles and CVs and use the 914-6 trailing arms and hubs ...

he didnt mention his stub axle choice..

assuming he meant /4


ahndy - whats the diff tween a /4 and /6 cv....???

the spline for the axle shaft ...

[Aaron Cox]

cv's have same bolt pattern... but the internal splines are differnt....


sees pretty sillty to make 2 sets of identical functioning parts....


thanks ahhhndy

good question ....

btw. EASY has a set of 914-6 axles with CVs. and yes, the spline is different for sure (i tried) ...

Hmmmmmmmmmmmm are you guys sure?? (oh, that's right, he said he's sure)

I was 'always' under the impression that -6 and -4 CV's and axles are the same. The stub axle for sure is different but the CV's and Axles???

Next, there's no such thing as 914-6 swing arms. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

So Pete, if you're getting 'loaded' 914 control arms off a -6 you'll simply need the stub axles. They'll bolt up to a 914 CV (I know that for sure).

Talk amongst yourselves...

well, as i said, EASY has a set that i was looking at a while ago when i was looking for stuff for my 944 conversion ...

we took a CV off the 914-6 axle shaft and the spline was different then any of the 914-4 shafts ...

so, there you go ...

i remember...
/6 CV joints were NLA... so you could convert to a 4 cylinder asseembly.....
then....
/4 CV's became NLA........

pretty stupid to make 2 identical funtioning parts.... but not make them interchangeable.....

like 411/914 vs 911 front suspension. a arms etc are physically the same, just different splining.......

914/6 drive shafts are bigger diameter than the /4, but you need to measure carefully. CV's are not interchangeable.
So why does the left 914/6 arm have a different part #?

[Brian Mifsud]

"Stupid??" Try "Heroic"....

Check out the two chapters in Ludvigsens "Excellence Was Expected" on the 914 development.

With VW playing fickle on the "handshake" agreement, as well as the creation of the VW-Audi distribution network.. I can easily imagine the redtape and bureacracy the product developers and engineers faced at Porsche when they were trying to come up with a list of parts that made economical sense. Porsche was trying to save costs by using as many 911 "bin" parts as they could, while VW was doing the same... they just had different "Bins"....

Aaron, I understand you are still a student of ME...not to dash your dreams, but once you get out of school and rack up some hours in whatever bureacracy employs you, you might begin to develop some sympathy for the grunts (since you will be one) who had to make the product happen.. no offense intended... I'm just tired out and jaded after doing this crap for 15 years... (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) Most likely, Porsche engineers HAD to do their own parts, just to cut thru the junk foisted upon them by the VW/Porsche/Audi relationships (or lack thereof)

TIME TO MARKET is NUMBER ONE. Anything that gets in the way of that goal quickly gets reprioritized.. even if that means saving "cost" later...

Beats me (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) They're 'identical'.

How about the right one?

[davep]

The right is the same, but I think the 914/6 left had a bracket for an oil line or something.

The 914 has what amounts to a unique rear suspension, so why the /4 and /6 had such different parts is a mystery. Okay, so the /4 had to use VW wheels for some reason. Same with the front suspension as only the brakes are VW. The A-arms have different spline counts for no apparent good reason. As a bean-counter I would have used the same parts as a 911 to get a volume discount on the 911 parts.

The difference? 914/6 CV joints have been NLA for 15-20 years, and 914/4 CV joints have been NLA for only a few months. Oh, and the spline count is different. The Cap'n

411 front suspension is coil over struts, like a super beetle. The only parts that May be the same are the early rotors, and possibly the calipers. The Cap'n

i stand corrected.... it was my understanding that the 914 borrowed its front suspension from a 411/412...

so they made a new setup identical to a 911.... just the splines are different.... (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

Wow!!!!

I went out flying tonight and thought that I would check my posting before going to bed and..........................

I had no idea what a response I would get. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)


What a history lesson!!!

my understanding from our discussion...
So w/ this pair of swing arms (from a 914 / 6) I would have to use my 914 / 4 axle shafts (they are 4 bolt) and find a pair of 914 /6 axle stubs ( which I am of the understanding that it has a matching 4 bolt pattern) and will be able to connect the axle to the swing arms for a happy 5 lug conversion / marriage!


Is this correct?

if so where does one find such an item and how much are we talking about $?

thanks all
Pete
