Think there is supposed to be oil in it for lubrication.
The issue is "Clean oil". The pump lubricates on a splash
in splash out mode which allows it to be a collector of
grime and sludge. That rod does not need to stick very much
to make a most impressive racket. First time I heard it I
thought my rod bearings were going. Keeping everything
clean works fine for me.
