    Mazzer Kony E disassembly and respray

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I thought I would put this in a new thread, original posting was from here.

    As you can see I wasn’t happy with the colour of my new grinder so decided to re spray it. *I have detailed the disassembly process in posts below.

    I ended up picking my paint colour from a Lamborghini website Arancio Ishtar as I thought I would stick with the Italians for colour choice. *The paint shop then mixed it up for me.

    Firstly, a few pictures of the new grinder, brand new out of the box. *It actually came with that tamper and the little stand. *Not sure if it is only those grinders that do not come with a tamp on the side of the doser that get these?? *But I cannot see myself using them. *Although the stand looks ok. * Could do with some rubber contact glued to it though. *I have a Bumper one so will not be using it. *I sold my pullman tamper with my machine, so will be up for a new Pullman or reg barber.

    Excuse the photos, most of them were taken with my Iphone or my wifes camera

    First step, was to remove the burr collar. *These are a bit different to the flat blades and you can get your fingers in there. *So there is a safety switch. *There is a little plastic extension on the hopper that slots into this little slot to depress a micro switch. *A trap for young players that don’t like to read manuals. *I was trying to run it without a hopper to test it as I didn’t want to take the hopper out of the plastic. *Took me a while to resort to the manual to see what the problem was.

    Also grinder must have been tested and reset. As it was reading 0000 but there was coffee residue in the burrs so obviously tested.

    close up of the slot for the safety switch.

    cooling fan,

    annoying screw that really serves no purpose, other than perhaps stopping you marking the paint with your PF. But they could have come up with something better for that. I am debating what to do with it. I might get machinist at work to make me something a bit prettier out of stainless.

    Strip Down continues

    I then removed the safety cover and the front doser chamber, tines and switches.


    The burrs comes out easily enough, socket and a wooden dowel on the ali bit below the burrs to stop the burr from turning. It is a reverse thread for those playing at home.

    Getting the top reduction gear section of the grinder was easy, just the four hex screws on top and it slides off. Then another hex bolt to remove the middle cog attached to the shaft (sorry forgot to take a photo of that). This whole chamber was full of grease. I didn’t get any photos as my hands were all greasy [ch9786]


    No photos I am afraid.

    the next bits got a bit tricky

    Removal of this section and the shaft had me confused for a while as I couldn’t find a parts diagram. *It wasn’t until I completely removed the grease that I saw what I needed to do. *
    1) The circular rail/teeth section actually slides into the housing. *You can pry it up. *
    2) This then covers 4 PH screws which need to be removed.
    3) Refer to the section below on removal of baseplate and electrics.
    4) Remove the 4 screws at the bottom of the plate from the bottom of the motor. *There is a bearing pressed into this plate. *The shaft is then pressed into that bearing. *There is another bearing at the top of the shaft, just under the plate you pull the screws out of at step 2.
    5) Turn the grinder upright and take a brass drift or block of wood and give the shaft a couple of short hard taps. *This will remove the top bearing from the cover. *Remove that cover.
    6) Now you should see the offending bearing and a black plastic plate. *You will need to get a micro bearing puller (I had a 4 inch but it was too big) *so I convinced machinist at work he needed a micro puller for his toolbox.
    7) Once the bearing is removed you have one last obstacle, the black pastic plate. *The shaft has grooves machined into it. The plate is a little undersized for the plate, which is then pressed onto the shaft. *You use your drift again to know the shaft through the plate. *The shaft will then drop out.
    8) I read somewhere you could get the stator out, if you heated it all up in an oven. *But I thought that was a bit of overkill [ch9786]

    picture of the top bearing pressed back into its housing.

    I used an appropriately sized socket to drive it in. Note this was the only difference in the reassembly process.
    1) I drove this bearing in first
    2) inserted the shaft and screwed in the bottom plate;
    3) pushed on the black plastic cover
    4) tapped on the top bearing cover until I could get the 4 screws in partially;
    5) then used the 4 screws to pull down the top plate, rotating them 1/4 a turn each to pull it down evenly

    Couple of pics of the stator and the plastic plate

    I shall prefix this with following statement "I am not an electrician this is just supplied for information, you should get a qualified electrician to do this part of the process"

    Removal of Electrical Components

    1) Unplug it the grinder
    2) Check the grinder is unplugged
    3) remove the 4 rubber feet
    4) remove the security torx bolt
    5) the plate will drop off.
    6) Check the grinder is still unplugged :)
    7) I found it easiest to remove some of the cables from the connectors on the base, rather than remove everything from the base. You can work out what to remove depending on how much of a pull down you are doing.
    8) I ended up cutting the 4 wires in the control box. The cable for this runs down the inside of the grinder to the base. It was all getting a bit complicated and I thought this was the easiest. I just re-soldered and heat shrinked them when I put it back together.
    9) The switch simply unscrews.

    Painting

    I used a 2 pack as it is supposed to be harder wearing. It did give me a better finish than I had achieved with acrylics in the past. However, it is pretty nasty stuff. I have a good respirator and it was only a small piece. But I wouldn’t be doing anything big with 2 pack without a booth and breathing apparatus.

    I sprayed with a touchup gun I have. It was only a small piece and I only bought 250ml of paint, so I didn’t want it to go everywhere.

    1) As it was brand new, I was fairly happy with the paint condition. I just rough sanded it with 400 grit to get a key.
    2) Primed it – next time get a tinted primer, dark grey is hard to cover with orange.
    3) Applied base coat;
    4) Applied clear coat;
    5) Wet and dry sand to make up for my lack of spray painting skills;
    6) Compounded it.

    Assembly

    was pretty much the reverse, apart from the way the bearings and shaft were put back.

    All up it took me about 4 hours of mucking around to get it all apart. 2 hours of that was trying to work out how to get the shaft out, and not having the correct puller.

    Once I got the correct puller, it took me 5 minutes to get the shaft out.

    It took me 2 hours to get it all back together.

    Painting took the longest. I am a bit of a perfectionist in these things and my spray painting experience has taught me patience and preparation and more preparation. Same with wet and dry sanding. Dont be too quick to rush upping the grades. I used a 1500 grit to smooth it all out and then went to a 2000 grit. I then used a cutting buff and finished with a polishing buff.

    All up the painting probably took me 1/2 a day.

    Sanding and buffing maybe about the same.

    the paint was a little expensive. I needed different thinners too and the clear coat requires a separate hardener. I think that totaled $150. But if you were to buy acrylic and clear coat and thinners, I would say it would still cost you $100.

    Everything else I already had.

    Pictures of the finished product

    awaiting the GS3 to arrive shortly and soon to have a matching orange paddle cover.

    Just clears the top cupboards. *I never measured it so I was a little nervous when I brought it home. *But plenty of room.

    Nice work on the Kony and helful post! Thanks for the disassembly pictures. I second the comments that you are a brave man. ;)

    I just got myself a second-hand Major E. No user manual came with. I could figure out the basic use and programming of the doses but they are a few things I cant do like reset the counter. Do you know how to do it? Is it in the manual?

    This isnt covered in the manual but theres probably a secret sequence of buttons that need to be pressed.

    If you want to reset it to ZERO - then the only way to do it is to sit there and press the double button until the clock winds back to 0000.

    Just place a post it note of the current reading as a reference for yourself.

    I think replies 4 and 5 might be of assistance.
    I don't have practical knowledge, just seems like the step you are up to.
