Hi Regis,
I think you mean to disassembly the headstock/spindle.
Looking at the pictures, your lathe is a South Bend 9" model "C" brazilian clone, made by Sanches Blanes Company.
There are few videos... https://www.youtube.com/watch?v=dUujw7JLIFQ e https://www.youtube.com/watch?v=U1agcVkQ63U
I strongly recomend you to buy a restoration manual (like this:https://www.ebay.com/itm/152597311432). It should help.
Good luck in the restoration!!
