Noisy 401
My everyday piecing machine is a 401. It's one that was partially frozen up when I purchased it. It's really noisy in the bobbin area. I kept thinking it was only when my bobbin was about empty, but I was wrong. (I recently bought a 503 that is really quiet, so this is more noticeable than before.)
I've just now greased the gears, oiled the part that moves when the feed dogs go up and down and and that oil spot under the bobbin. Did I miss something?
