Does any one have a Part # and photo of 911R rear axles? And are they the same as a 906 axle? Did they take the reinforced Nadella axle?
Thanks,
John

Is that the reinforced Nadella flanged axel? There's a picture
on the board here somewhere.

Don't they use the hollow shaft Nadella axles? I'd like to know why 911 owners think they are unsafe to use but not 904-906 owners.
a. I don't know them as being unsafe but as unreliable.I'd like to know why 911 owners think they are unsafe to use but not 904-906 owners.
b. On a 904 the nadella shaft is shorter and thicker and also their use is different I would think. The most destructive force is probably w/ stop and go (like on the street) while on a track it stays in motion once the light has become green.
Just a thought.

Me and another member were having a discussion about the Nadella axles. Were the 901-911 axles sliding & the 904-906 solid?

I recently rebuilt a 911R trans and fitted it with both kinds of drive flanges, so they could go back and forth between the original nadella axles which were hollow and a set of lobro axles. One R owner I know had an nadella break and when they flail around, they can make a mess of things. Maybe not dangerous but can cause lots of damage. The sliding spline axles if I'm not mistaken were developed by Dick Elverud at the time at Monties Motors in Portland Oregon, as a replacement for the nadella. They re-used the stub axle end and the attachment plate for the drive flange and replaced the middle with the sliding unit. Gordon PS This trans had a 906 pinion shaft with castle nut instead of a streatch bolt. Only 2nd one I ever seen.
Here is the thread with the African T/R, where I posted the 2 types of Nadellas:

Besides the weight and axle diamenter they are identical.
Concerning breakage of the Nadellas Porsche recommended complete exchange every 10.000km. Nadellas are not designed for rebuild, but in my personal experience changing the bearings is possible as long as the bearing seat is fine.
Hope it helps.

The Lobro is a CV and will be much more kind on the transmission than a Hooke Coupling.
A Hooke Coupling is clearly not a CV joint and will cause axial loads as it shortens with twist.
The idea of a sliding spline seems good but it will not slide until the axial force is greater than the locked in torque.
What can break...the axle or the bearings?

I asked Dick about the nadella axles again and he said they didn't break very often. The outer U joint dried up, probably because of extra moisture and started making noise. His first repairs was to machine and put a spicer U joint with retaining clips and zerk fittings in place. When the inner scissors joints had problems, he finally made the sliding axles. Gordon
