Yes thank you but that will be my last option, only if I fail to repair it myself and can't find eu service.
Try asking the owner of Nagravox - perhaps he knows what are the parts you need. The most critical parameter after bearing quality in these motors is bearing pre-loading and as he sells these parts, including beleville washers for Studer motors, perhaps he can help you. https://nagravox.com

Although you didn't help me much, I thank everyone for their traying and good intentions.
Studer never produced exploded views of the A80 Capstan motor. If yours is defective, your best bet is to find a spare from a deck that someone is parting out. Once you have that, feel free to open up the original and look at it.

A schematic wont help you unless you can resurface the shaft and mic it properly afterward. Most motor winding places, and tape deck repair facilities cant do that. There is no point in changing ball bearings and leaving everything else worn out of tolerance. W&F will be all over the place. There are few areas that I do not recommend folks get into with their A80. This is one of them.

I'm afraid you are right and i will not succeed without the precise instructions to assemble this motor myself. I am even convinced that this was not originally a housing and shaft for 2 ball bearings, but rather something improvised but not good enough.

You might give Zeltec R&D in NYC a call...Dan might able to help. Never send anything to Athan...George is bad news.

from what I´ve heard Audiohouse in Switzerland is THE ONLY WAY to go
Surely the best way, if it was not for the need of temporary export custom papers I would already have sent one for refurbishment to Audiohouse. But IMHO, some common sense, a decent wow and flutter meter and an audio spectrometer can be a good alternative for skilled amateurs.

In fact, perhaps sometime in Winter, when nights are longer, I will take the challenge and will open one of my spare A80 capstan motors ...

Mine is on its way to Audiohouse as well as the two spooling motors.
