I thought gears all needed grease, but on the upper gear on the Singer 201, the one you get to behind the round plate on the back, all I can find is the information to OIL it. Does it not need greased? (It doesn't look like there has ever been grease on it.) Is it not a gear, though it looks to me like what I think of as a gear?

The gear I am talking about is the arrow to the right of the "B" in the photo below.
