So I need to get some 100mm output flanges to go with my 944 axles I want to use on my 914. I am thinking they come out of a 915. What do I really need to look for with my 901 box and is the 100mm measured from the bolt spacing or the distance across or?
I also was asked if I need coarse or fine spline. Ummmm.... 901 guys help me out here. Dr. Evil? Slits? anyone?
Coarse spline from a late '70ies 915 tranny ...
I forgot the exact years, but somewhere around '76 - '78 i think.
Andy
Thanks Andy
100mm cv output flanges on the 923/02 tranny (912e) and 915/44 tranny (911) both 1976. 1972-73 911's trannys have 108mm cv output flanges, those might be the ones which interchange with 901's (914) diffs. I'd like to do tranny swaps (914 to915) without impacting axle swaps.
The output flanges on the 1976 912e have a raised lip which go around the 100mm cv. The 1976 911 tranny (915/44) does not have a lip, but does feature a raised deck to allow for grease I'm guessing.
I machined the 914 axles to accept the 944t cv's because the 944 axles are long. They look iffy to me, might spring for custom instead or go the PMS way. Gotta loosen the expansion bolts and see if they slide into the 901/914 diffs. The 72-73 911 output flanges I have fit a 108mm cv, the 1976 911 5-spd and the 1976 912e 5-spd fit the 100mm cv's but the 912e flanges have an outer lip to surround the cv OD.
I have everything I need other than the output flanges. The guy I bought this from had a 3.2 with a 915 and this axle setup. I have the early 911 hubs and all so I figure it would be good to do. I have a spacer that adjusts for the problem in length. Now I just need Andy to see if Easy has some for as little as possible or if GPR has some.
If you can't find any factory stub axles, Todd at Precision Alloy can make you a set out of your 914 set. He does very nice work and reasonable $$.

You can call EASY too. I've gotten a few things from them (that they've shipped to me) and been very happy with the price.
I got two sets from Parts Heaven in Hayward. Try them too.
I have some 901's and 914/901's for some bug applications. I am getting the idea from this thread that the 914 axle is easier to break than the 901 tranny. That surprises me. As light as buggies are I was hoping the 901 would hold up to a suby but I hadn't considered the axles as being a problem.
I run a stock 901 behind my 3.6L /6 ...
So far, so good. I think they can hold up pretty well if you're older than 25 and got through your "must burn rubber on every light" phase with a different car.
I don't use 1st gear anymore as i have been told it is the weakest spot in the 901. I got plenty of torque and taking off in 2nd is no problem at all ...
As for the axles, i went with the modified 914 axles shaft and 100mm 944 CVs. No problems there either so far.
HOW TO: Convert to real 5-lug in the rear using 944 CVs
http://www.914world.com/bbs2/index.php?showtopic=80641
By using the modified 914 axles shaft, you eliminate any length problems and there's no need for spacers.
The 915 coarse spline output flanges are the same "depth" as the 901 output flanges.
Andy
Does anyone know if vw bus cvs are as good as 944 cvs?
Jon,
I have a spare pair of 915 sporto output flanges. They're about 3/8" longer than the manual transmission flanges and make up half the difference in length between the shorter 911 axle and the longer 914 axle. I've been using a pair on mine with the 911 axle, stub, and hub for a couple years no problem. I'm not sure the length of the 944 axle, but these are available if you want to try....
I have an early 915 at Steve Wiley's that we are using for parts. Ask him what the flanges are......
PM him, screen name is sww914
Oh. Well, the guy I bought these from had been using them on his 914 so I am guessing they are fine.
I almost bought a set from OTTO a few years back, i think he wanted 200 a pair tho....
He had them matted to a hot 3.2 and all was fine. I really don't believe they are any longer than the 914 axles I have. Maybe they were already alterd or something. I will have to look into it as it looks like he did everything you said to do in your thread. I'll check but need to get the output flanges before it even matters.
Turns out they are longer than the original axles. So anyone here know what will happen if I run them like this without altering them?
Andy, any luck with Easy?
Okay, so after reading Andy's writeup again I think it would be easy enough to use the 914 shaft.
915 trans output flange # 923.332.209.02 coarse spline , checked in diff of 914 / 901 same height as the 914 output flanges . I have a set I checked the part number on to use for the 944 cv setup on 5 lug conversion.

So are you going to do this as well or sell me the output flanges?
If you are going to do this I can make you the half shafts you will need with the 914 shaft and 944 CVs. I am planning on making four. I have two 944 alxes I was going to use the CVs on to make spares and I am buying new CVs to make the ones that will go on my car. I also have plenty of 914 shafts to do this with.

Just buy the proper length 28 spline axle from Sway-a-Way and be done with it. $3??.00 clams. No adapters. No machining. All the 911 stuff bolts right up. Done.
Why would I do that when all I need now are the output flanges and I am done?
You're right... you should have done it a long time ago.
I know. I just never bothered until now and my car was running fine. I just figured now would be the perfect time since I am doing everything else.
Why are people telling me the six bolt 100mm flange doesn't exist when I have a picture of it right here? They keep telling me the 100mm flange only came in four bolt with two studs
Attached image(s)
Cause that's a 108 or someone drilled the nubs.
Really? So all I would need to do is drill the nubs and tap it to work right?
Andy?
1/2 joking with you. I do believe you can drill the nubs though.
I got the entire drive line out of a 1970 911 and simply swapped the axles. Seems a bit over-simplfied when compared to all this stuff.
I know, I know... you just need flanges.
Thanks for checking for me Andy.
So anyone have what I need?
Is that a "Bro"?
Jon, check the PP classifieds.
As to what species he is ,doesn't concern me ,but what the heck is he drilling the shift flange for -drainage ???
Jaxdream
Species? Well Sir Andy is German if that is what you are reffering to
I believe he is drilling to use the JWest linkage. Don't quote me on that but since he isn't speaking up that is my guess. Drainage would be out of the bottom
Is the flange you are looking for is this:
915.332.209.01
Then here is an site for $100.00/flange: http://dcauto.gotdns.com/illustration/index/44894393
Jon call monty.
As for DC Auto , I have been waitng for 2 parts I paid for since april 08.
Just got a PM on the PP board from a guy just North of my. He has these at a very affordable price
These look right don't they? They look correct to me but what do I know
Attached thumbnail(s)
I will let you know. I sent him and email a few seconds ago asking.
Ayupp, those look right ... 100mm?
Andy
I found another set of these as well if someone is looking to do this. The guy would like $90 for them shipped.
At any rate... looks like I will have my CVs done by the time the engine is ready to go back in .
