[R-390] R-390A gear train cleaning

Should have thought of Google.

Those are also known as Snap Rings (the ones with the small hole on each
side) and C clips.

McMaster Carr for sure. Probably local fastener shops as well

I've never heard the term but I think a circlip is those little tiny thin
circular clips that hold the gears onto the shaft, they are really hard to
snap back in place. Actually I just googled it and there are images of them
all over the place.
