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? |

Why not do it the simple way as the Dr says.? Get a set of repro stub axle from Otto's. They bolt to the 4 axle and mate to the -6 hub.
-6 axles and 4 axles are the same diameter and length. I cannot remember if the spline count for the axle shaft is different. -6 CVs have 6 bolts and no pins. -4 have 4 bolts and 2 pins. Both CV joints for the 6 and 4 are NLA. -6 rear hubs and 69-73 911 rear hubs are the same part number. Stub axles for the 69-73 911 will fit in the hub. These hubs are 100mm. I do not know if the 100mm CV joint will fit onto the 914-4 shaft. Attached image(s) |

I do not know if the 100mm CV joint will fit onto the 914-4 shaft. /6 CVs have pins, IIRC (and I think I do!) 100mm CV joints that fit 911s WILL NOT fit /4 axles, and that's what this whole discussion is about. (I use the term discussion loosely.) As has been repeated seemingly endlessly, the spline counts are different ......... They'll fit 914/6 axles, though, I'm pretty sure, and that would solve the problem, IF we had some /6 axles. But we don't. What we DO have are the inner 100mm flanges, 100 mm outer stubs, and a number of (probably) useable 100 mm CV joints. Boots are not an issue. We also have a number of /4 axles, complete with CVs, and 914 drive flanges. What we DO NOT have are (1) 914/6 stub axle or (2) 914/6 axle shafts. We need one or the other. The least complicated (and potentially the least expensive) option is gonna be the single 914/6 stub axle. The Cap'n |
