Replacement upper burr carrier for the Turin DF64 coffee grinder, which is also known as the Solo or Giotto DF64 single dose grinder. The upper burr carrier holds the top burr in place. It is also the burr that moves up and down when the grind size is adjusted. It does not turn like the bottom burr does. If burr alignment is done, there are three positions for the burr to be in, each position can vary in terms of alignment. it is best to check the alignment of all three positions using the marker method prior to shimming the burrs.
