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? |

Here's some information for you Mike (and anybody else that cares)
1972-1975 Porsche 911/930 CV Axles: Splines for cage are 28 teeth. Bar is 1.037" diameter and 19 7/16" long. CVs are 4.250" diameter and 1.220" thick. CVs are bolt on 4 holes and 2 locating pins. 1969 - 1971 911/930 CV axles ... Splines are 28 teeth. Bar is 1.037" diameter and 19 1/8" long. CVs are 4.250" diameter and 1.535 thick. CVs are bolt on 4 holes and 2 locating pins. 1966 - 1968 Porsche 912 CVs are 0.950" in diameter and 16 1/8" long. Splines are 33 teeth for cage. CVs are 3.669 diameter. CVs are bolt on 6 holes. (Also used on '66-'79 Beetle). 1969 - 1976 Porsche 914 .... Splines are 33 teeth for cage. Bar is 1.020" diameter and 20 1/4" long. CVs are 3.669" diameter and 1.220" thick CVs are bolt on 4 holes and 2 locating pins. Now, what would a 914/6 CV axle assembly be? And according to my research the stub axle 901 332 232 00 was used from 1969 - 1977 (28 spline). Further ... The '69 - '75 had two bumps on each end of the bar. The Beetle/912/914 has one bump. |

Now, what would a 914/6 CV axle assembly be? I "think" the difference between a 914/6 axle and CV combo and a 914/4 axle and CV combo is... Length is the same. 914/6 axle is slightly larger in diameter (1mm or so). 914/6 axle and CVs have 28 spline. 914/4 axle and CV have 33 spline. Bolt pattern and CV diameter is the same on both. If my understanding is correct, you can direclty swap one for the other. If I am wrong, someone correct me, so I can update my wiki article with correct info. PS: thanks for the other dimension info in your post! |
