    How to replace Isomac Gran Macinino grinders

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Help please. *Have decided to replace my grinders on my Gran Macinino and have come unstuck when trying to replace the concial grinder. *Unable to work out how to remove as it rotates around a centre shaft and held on by a nut.
    Anybody have one of these and can provide some guidance.

    The nuts on conical grinders are usuallu a left hand thread which means you turn it the opposite way to undo it.

    So it will probably undo by turning it clockwise which on a normal screw/bolt would tighten it.

    Re: How to replace Isomac Gran Macinino grinders

    When I first read the topic, the immediate answer that came to mind is:

    1) Sell it.
    2) Buy yourself a large conical like Kony-e or K10WBC.
    ....without a doubt the best way to replace your Isomac grinder! :P

    all tongue in cheek - glad you solved your problem, Coopers. ;)

    I am also trying to replace the burr of my isomac professionale.

    I can successfully remove the bottom part of the burr, but stuck in removing top one.

    I wonder if there is any suggestion?

    G'day Colin...

    I think it will need to be pressed out, if memory serves; but I can't remember whether the Isomac fixed burr is locked into place with grub screws...

    Thanks, Dimal,

    I have looked around the top part, there is a hole, and I was also thinking maybe its for grub screw.

    End up I can not see anything hold the burr.

    The attached photo is the part I want to replace.

    I will give it try again (with press out), see how it goes.

    Something that might make it a bit easier to press out, would be to hit the inside of the burr with some freeze spray to get it really cold so that it shrinks a little bit. Then try to press or gently tap it out. Looking at your photo, it appears as though there is a 'flat' on one side of the burr to lock it into place and prevent it spinning. A bit simpler than separate grub screws...

    Thanks a lot, Mal,

    I will give it a try once I find something can sit the plastic thingy.

    Really appreciate for your advice.
