Oil for Simonet Motor

Hello,

I have a Simonet Overhead drive motor for my Schaublin 102. I cleaned out the motor and now it is running dry. I was wondering if anyone knew what type of motor I should use for it?

Here is a link where you can see a picture of the motor in the over head unit section.

Simonet DC 12 / DZ 45 Lathes - Anglo-Swiss Tools

Thanks!
