Andre,

Contact the Sony parts distributor(s) in your country, they might still
have some belts available, and hopefully will have a copy of the service
manual. There is not much to adjust in these mechanisms, unless someone
has forced or bent something. The biggest issue is lubrication. Many
of the old oils and greases will have dried out and turned to putty.
The old lubes need to be cleaned out before applying fresh lubes. I
would not take apart the entire mechanism, but threat the symptoms on a
piece by piece basis.

Unless you have alignment tapes and proper test equipment, I would not
try to align the heads. Also, if the heads have a lot of ware, the worn
groves in them can cause edge damage to tapes if you try to re-align
them.

Hello everybody,

I own an audio tape recorder Sony TC-366, 30 years old...
How to find spare belts ?
Where to find the service manual to adjust the mechanism ?

Yes it's an old timer but I own so much tapes with family souvenirs...
And it was a very fine recorder.
Sure, DVD recorders are better but....
