Hi,

I should know the ZF number punched on the housing of the early 8-disk LSD
This number is not a porsche spare part number , it's the internal number of the manufacturer Zahnradfabrik Friedrichshafen.
The number reads like this : 4061 XXX XXX or 4061 XXX

See attached picture ...unfortunately it doesn't show all digits.
I've found this picture here on rennlist .

TIA,

Thommy

Moin,

My later style LSD has the number 4061006320 33389 S40.

Earlier style LSD numbers found on Rennlist: 4061006205, 4061006250, 4061006293.

Why do you need the number?

Hi Aryan,

many thanks for the numbers. A specialist (www.limitedslip.de) needs these numbers to order parts from ZF previously to an overhaul of my LSD . It seems that not only the friction disks are worn out but maybe also the bevel pinions etc inside.
At Porsche some LSD parts are already sold out.

Thanks for the link, I need to overhaul my LSD before I put it in.

Does the ZF number 4061006320 always mean '87-'89 LSD? What is the significance of the second part of the number, for example 121782S40?

Tuomo, I think you should make contact with the ZF company in Germany and ask your questions about the numbers.

Could do that, or just try it to see if it fits into the '87-'98 rear end.
