911 mj 67: Lobro or Nadella axles?

[softwindow]

Is it correct that the change from Nadella to Lobro axles took place in July 66 and 67 models only had Lobro axles.


Kind regards.

If you ordered an LSD you would get Nadellas in 1967.

Hallo Andy, what does "LSD" mean? In german it is a drug that causes hallucinations.

Sorry, but my English is not the best, my mother language is German.

what does "LSD" mean?

Bernd, LSD = Sperrdifferential (Limited Slip Differential).

Thank you Jon,
is it possible to get this information from the Kardex?

The first Kardex from the Targa 500248 delivered in march 67 shows the gear number 131.161/902/1 5Gang.
the second Kardex from Targa 500441S delivered in april 67 shows the gear number 104.847/901/02.

Which axles were original: Lobro or Nadella?

Kind regards

Bernd,

For 911 mj 67, the standard axle for all models was Löbro. As Andy said, Nadella axles were used with a ZF LSD (Sperrdifferential).
The Kardex should note "Sperrdifferential" if one was ordered and installed.

At the 50th Parade, I talked to Chuck Stoddard about his 67S with LSD. He said Porsche sent him Lobro axles, trans drive flanges and stub axles as an update for his S. Jon? Was there a service bulletin or warranty or recall regarding the Nedella axles? Or was it just for Chuck? G

Gordon, there were several factory references to using only Nadella axles with the early ZF LSD.

It sounds like Chuck's 67S was built with Nadellas, and the factory sent him replacement parts for it sometime later.
It's possible that by 68 there may have been a Löbro option for the ZF diff, but I don't think I have any factory reference about it.

The factory spare parts catalog through model year 68 only shows a Nadella flange for the limited slip differential, and says "Use only together with articulated shaft NADELLA".
The factory workshop manual also states "The ZF multiple disc self locking differential can be installed only in connection with the NADELLA half shafts."

I agree that if sperrdifferential is listed on the Kardex, then the LSD was factory installed. I know of several coupes with LSD but no Targas. My understanding is that the aluminum trans case took the 904 LSD, but that the magnesium case took a different version, and that was delayed into the 1969 calendar year. Some cars ordered with LSD did not receive them since the parts were not available on time.

My '67 911S Targa, 500 010 had LSD and Nadellas. Of course, it was specially built for Ferry Porsche.
