    Rocky service Sydney?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Anyone know anywhere in the Inner West that will clean and service Racilio grinders?
    It probably needs new Burrs as well, how much does that cost?

    Its pretty much a simple DIY project Redrich, about all you need is a a screwdriver with a decent blade, this video is helpful https://www.youtube.com/watch?v=PmxC1mhiwqQ if you need burrs they are available here Rancilio Coffee Grinder Parts make sure you buy genuine parts.

    Yep...

    Genuine OEM Burr-sets are definitely the right way to go. Although the Generic Burr-sets are a little cheaper to buy at the outset, they don't last anywhere near as long as the real deal.

    Found this out the hard way with a set of new (generic) burrs for a La San Marco commercial grinder I bought. After only six months or so they were noticeably falling off in performance coupled with poorer quality in the cup. Decided I should inspect them and discovered that the cutting edges were already 'rounding off'. Pretty unbelievable after such a short time and with only about 40-45 Kg of freshly roasted beans later.

    In the mean time, my son was after a replacement grinder for his setup and since the LSM was surplus to my needs, he bought it off me and replaced the burrs with a new set of OEM burrs. That was about 2 years ago and they are still performing as good as new. Pays to stick with the good stuff...

    I just opened up it because I wanted to check the calibration. The burr housing is very difficult to turn, I cannot get it tight enough to stop the nut in the centre from turning.
    I'm doing something wrong or is there another problem?

    As you said in your original post, probably needs a good clean.

    Pay particular attention to the threads, whatever you do don't cross thread the burr carrier when putting it back together, then you will need a tech to rescue you.

    Just so's we're all talking about the same thing, have attached a parts breakdown drawing and legend. Perhaps you can refer to this so that we know exactly what you're referring to...

    It's the upper burr carrier I'm referring to. The calibration tutorials tell you to tighten it until the Burrs are touching, then dial it back. I can't get it to the point where they are touching. Seems I need to try to get it off and check/clean the threads.

    Yep, that's exactly what you need to do.

    Success. I got off tonight and cleaned the threads out and also a bit of the gunk in the area. I also put a little olive oil on the threads and it screwed right down and is now properly zeroed.
    I think I will still replace the burrs but I wanted to make sure there was nothing else wrong. I was initially going to use WD40 but decided it smelt too much. Will the olive oil be okay? I have some beard trimmer oil as well, would that be a better option?

    This all started because I got a second hand EM6910 at the weekend. My first few shots out of it have been fast and thin with barely any crema. I suspected there was a problem with the grinder because the grounds were not as fine as I'm used to. So we'll see how it goes now.

    WD40 - bad! (basically kerosene I think!) Beard Oil?!? Guess it's not toxic… buuuuuutttt…

    Olive Oil will be fine - just a very light smear though on a cotton bud is what I've used before, or you'll end up gunking it all up again. Shouldn't need much to get it running smoothly.

    Glad to here it is zero'ing again well though

    Cheers Matt

    The best stuff to use actually, is Graphite Powder, as anything wet will eventually (or quickly) attract coffee particles and gunk up the works again. Easy to obtain and quite cheap from somewhere like Bunnings or a Locksmith. You only need to apply a smear around the thread using a small artist's brush and then run the Upper Burr Carrier in and out all the way a couple of times to ensure it is coating the thread all the way through.

    It's not grinding fine enough, so i'll be moving on to burr replacement at the weekend. I'll grab some graphite power as well and give that a go.

    Burr replacement success. The grinder now easily chokes the em6910 and needs to be dialled well back from zero. Now to master the coffee machine.
