Product review (5 stars): Perfect fit and functionality for older and newer machines
Perfect drop in replacement for my older Scotsman ice machine.  I was wondering what the different housings were for but apparently they send the blue one for the older ones and the green one for the newer ice machines.  The "newer" ones are from July '04 onward.  The blue one uses a bronze bushing as a top bearing (up until July '04) and the green one uses a ball bearing at the top of the rotor (use began July '04).  I used the blue one and it works perfect.  No surprise as it's the exact part made by Scotsman.
