    Gino Rossi MC conical burrs removal

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have just bought a neglected Gino Rossi MC grinder; it smelled rank so I have decided to strip it and give it a good clean.

    I have removed the left hand tread nut which holds the rotating burr but this does not seem to want to come out, have I missed something or it is just seized? How can I loosen it from the shaft without damaging the motor?

    Also, what kind of grease should I use to lubricate the dosing mechanism when I re-assemble the doser, I guess some sort of food-grade grease?

    ...... also the burrs look pretty worn to me (but I’m no expert but if someone tells me how to post photos I’ll be happy to listen to someone disagreeing with me in regard), I cannot find any online parts store selling them. I remember reading a while ago a post where someone posted a table listing all the compatible conical burrs across all makes but I cannot find it anymore, anyone can help with that?
    Thanks in advance

    Why don't you contact site sponsor Coffee Parts and ask them? If they don't have the burrs, they may be able to source them for you.

    A Conical Burr sits on a tapered drive shaft.
    So given the grinders current description of course it'll be stuck on.
    Use heatgun. Or spray with CRC, leave sit, then use some very gentle persuasion.

    Actually most conical burrs ( including Rossi ones) are keyed to a straight shaft, not wedged onto a tapered shaft. But if the burrs haven't been removed for a long time they will likely be stuck on. In a few extreme cases I have required a small gear puller to remove these.

    MGT well spotted & picked up on. I dips my lid to you. Yes a woodruff key or similar.
    My apols to the OP for forgetting this 'key' piece of info. !! giggled like a schoolgirl....
    Exactly right.

    And Gt's reference to 'getting stuck' I'm sure refers to how the trapped grinds,
    the longer a grinder IS NOT regularly cleaned, then over time releases moisture and literally turns into a
    grinding paste that eventually becomes a thick sticky paste that basically binds up everything it's in contact with.
