I recently got hold of a La Cimbali MD6 grinder from a closed cafe. Although it is working, it has not been serviced in at least 10 years. In short, it needs a good clean (and probable burr replacement). The grind selector was stuck which indicated a lot of bound muck. After a bit of elbow grease I managed to remove the top brass burr holder. OMG - there was so much caked on grinds (even starting to oxidize the brass). I managed to get the top fixed burr off (after removing a stack of caked on grinds) and discovered a colony of mites or insects living under the burr. I suspect there may have been a few insects parts served with the coffee! I also finally managed to get the lower moving burr off however i need to get the brass holder off as I suspect there is a lot of crud under it. Trouble is, not quite sure how to do it. There is a central black plastic knob. I suspect I need to detach the burr holder from the motor axle but have no idea how. With brass being a brittle metal I don't want to force anything so am hoping some experts can help out. I also want to remove the grinds hopper and give a good wash in soapy water as it is filthy. But how does one do this in minimal steps?
Also, stupid question, but what is the black projection that sticks out above where the portafilter used for?
Oh, and when I take the top off the grinds hopper, there looks like a screw hole but no screw. Should there be one for some reason?
Thanks
