Original Elite Rock Turntable w/Excalibur Arm

There are a few of you who have this turntable and use it regularly. Here are my questions:

1. Where can I obtain a flat turntable belt?
2. Where can I obtain trough and bearing fluid?
3. Is it possible to use very lite sythetic motor oil?

Thank you very much for your response.
try LPgear.com they had a belt for my Sonograph-SG3 that's been discontinued for 10+ years,a C-J product. They have a wide variety of gear for LP playing.
Uru975 thank you much for this information. I will try them to see what's happening.
