Last night I started the reassembly of my Rio/Mazzer SJ and started with the lower burr carrier. For those who have removed and replaced it know there is a pin that runs through the spindle and that the placement of the lower burr carrier has to be just right. The lower burr carrier is a tight fit on the spindle as well.
Once I felt I had the lower burr carrier on, I added the upper burr carrier and as mentioned above it can be tricky. I ultimately won that battle and got it screwed on.
When adjusting the grind to a finer setting, I'm not entirely sure if it screws down as far as it did when I received it. I'm kinda wondering if the lower burr carrier isn't on all the way. I really torqued down the lower burr retaining bolt and looking through the grind chute it appears that there isn't much space between the bottom of the lower burr carrier and the top of the grinder well. Anyone know what the clearance should be?
Is there any trick to make sure that the burr carrier is properly seated? The grind seemed powdery at the setting a touch above where the burrs touch. I'm also afraid that if its not properly seated my grind quality will be seriously compromised.
