I've imported this machine from the US into Europe. Not aware of the 110/220v issue, I plugged it in and caused a short-circuit. The governor screw of the device came apart during the incident. I ordered a new governor as well as a power converter (220 to 110v). After assembling the new governor the device now makes a loud sound and produces a burning smell. The sound seems to be caused by the governor pushing against the brass part of the speed-control plate. The governor did the same after I reassembled to old one (whilst using the purchased power converter). However, when I put the machine on full speed, the sound dies away and the locomotion becomes regular. I've tried tuning the speed by adjusting the top two, and bottom one, screws, but to no avail. As soon as I turn on the kitchenaid, the governor pushes against the speedcontrol plate which produces a loud sound, as well as green sparks. To get a better image of the issue at hand, please take a quick look at below video: https://www.youtube.com/watch?v=TbgW13ZQN-w&list=UUHkfUtredxlGLEIXZLBGmz What can I do to fix this device? Will it even work in Europe with a power converter, or should I give up and buy a European model? Many thanks in advance!
That green sparking looks to be in the area of the off/on contacts, look for something causing them to not be touching properly. The speed control lever has a ramp on the plastic end that goes through that speed control plate to move that copper arm, that is the off/on switch. I'm wondering if maybe the voltage from your converter is not fully as it should be, just a thought. If you wanted to properly convert to Euro voltage you need an armature, a set of fields and that small PCB with the 6 wires off it just above the black speed control plate. You set your slowest speed (#1) with the 2 screws and locknuts on the top of the speed control plate. 13 to 15 rpm in 15 seconds, I do it by running mixer with palm of my hand in position to be bumped by the silver shaft on the planetary each revolution, count them and watch your second hand. Once that is done you set that bottom screw to just increase the speed as you click the lever into speed 2. Had a look at your video, the governor does not sound happy, it could be the back plate adjustment out of whack to cause it. You can email me with more questions if you like [email protected]

Hi, It could be the variable speed switch. (bad) Replace it for a new one. Good luck.
Did it start clattering before or after it was re-greased? The K5ss by Hobart is an excellent mixer and there is no reason why it can't go on for a bunch more years. First you can get clattering if the brushes are less than 5/16th inch long, But that is not usual.
I would think that the rear bearing which is in the center at the rear may be more your problem, That bearing is behind the speed control switch and behind the governor (don't discount the governor being the problem) and is attached by two 3/8th nuts and slides onto the two guide slides that hold the motor parts in place. What i have found over the years is that 1.) the studs can bend (happens but not often) 2.) the bearing which is in the center of the big aluminum housing, (Called rear bearing assembly) moves over the years and causes humming and clattering.
So what to do about it? Loosen the two nuts a turn or two (do not remove) look at the top of the the bearing assembly and you will see a metal tab (used to attach the rear cover) (make sure the bowl and beaters are not attached to the machine) now plug it in and turn it to stir speed or number 2 position, put your finger on top of the tab and press down while the mixer is running, you should hear a change in pitch, and it should effect the clattering noise, (It will go up or down, or you may hear a new noise a light humming) (The humming is caused by the armature no longer in the center of the motor field and getting to close to the stator of the motor while it is operating, when it is out of center the developed magnetic field that causes the armature to turn gives off the humming noise because it is out of center or balance) if you notice that the clattering gets louder or softer by pushing down or pulling up you have to play with it to find the sweet spot, when you find it tighten the two nuts down just enough to hold it in place and no more. It takes a while and you wont hurt the machine but never go above speed two while doing this. If that fixes the problem you may have to do it more than once as the machine continues to age or if you move the machine around a lot. the real problem is the armature needs replacing (if this is the problem). Next you may have the machine timed wrong and that has to do with the speed control switch entirely, let us know what you find if these are not the problems we have a ways to go but they are the usual culprits with your symtom.
