Any other Hobart grinder owners here?

I have an old Hobart 4212 1/3 hp grinder that I was given about 15 years ago by a friend who was moving out of state. It has always worked fine but the last time I used it, it got pretty warm. I'm guessing the gearbox is dry but haven't taken it apart yet. The machine is approx 60 years old based on the research I've done.

Anyone else have an old Hobart and found a similar issue? What do you use for gear lube?

I'd hit the Hobart website and see if they have info for that model. Great grinders.
