VERY informative video-you know what you are doing- I had a bearing on the worm gear in wrong and worked it out with your video--WELL DONE nand the camera work was very good too
I like your very German attention to mechanical detail. Tell me, would a balanced washer of 3/4 inch outer diameter, affixed to the motor arbor just behind the contact point between the arbor and the large gear on the worm gear assembly it drives, prevent the grease from accumulating on the back of the arbor more efficiently than would packing additional grease above the gear contact point in the gear case? I understand this simple machine isn't as complex as an F-1 motor but it's fun to make this basic, gear-reduction design as durable as possible.
Could be tried. Usually, an extra washer will wear away either inside or outside due to friction against something. By design, tight tolerances and a rubber O-ring keep the grease inside housings.
Hello. My mixers gears are all in perfect condition and the teeth are all there.... but I hear a grinding now that I put it back together? It wasn't doing that before I opened it up. It was fine and working fine... what may have went wrong? Thanks also: I have the K5SS bowl-lift model,
If it aint` broken, don`t start fixin`. Gear teeth are always worn on one side, evident after a few hours of run-in. Any component, shaft, motor winding, wire, screw, spacer or washer could be put back wrong, backward, placed wrong, sequenced wrong, rotated wrong, aligned wrong, not tightened, overtightened, contaminated. It`s a simple mechanical fit issue, let us know where it was when you`ve found it.
Im thinking of getting a Bosch instead. Not sure yet....just bought my kitchenaid 600 from Costco. Its very loud on stir, high pitched. Then I see all sorts of bad reviews. And the bowl doest come completely clean...grey comes off, and Ive used barkeepers friend. Did anyone have grey stuff come off their bowls, and did it get completely clean?
Oh dear. Nothing should come off bowls, beaters, anything in contact with food. See ua-cam.com/video/irUwnzaXs2Y/v-deo.html Surfaces should be stainless steel and pristine.
When you "dry fitted" the worm gear, why were you not concerned with bushing movement. Clearly they were moving. Are the bushing machined flats intended to be installed vertically or horizontally? If the worm moves away from the "pink" gear, and, the worm gear moves away from the motor drive gear, you got a problem? Right? Thanks for the video. 💖
theoverengineer Thanks for responding so promptly! Maybe I wasn't clear with my question, so I will try again. Since you installed the bushings vertically, allowing the movement, shouldn't you have rotated the bushing 90°? It's not a clearence issue but but an engineering and installation issue. Thanks again!
theoverengineer I just found the parts list from Kitchenaid, which clearly shows the flats positioned horizontal, which eliminates any play in the gears relationship. I think I've figuered it out. Thx again.
Regarding my model 600:The planetary movement on my mixer binds up at one particular point in the cycle. I have removed and inspected both the planetary and the gear that drives it, both appear fine, yet when I interact the drive gear with the planetary and turn it by hand it continues to get bound up at one particular location. Any idea why this is happening? Thank you..
The axes of rotation are not parallel any more, they tilt towards each other at one point and seize up. Caused by top and bottom axle pivots and axle wear.
Thank you very much Good job. Can you please show us by video how to replace the carbon brushes for the kitchenaid heavy duty (7quart) Model no 5KSM7591XBER Thank you again
The external snap ring. There is not much vertical load on it, just the weight of the gears+shaft assy., should be in place, intact. Bushing does wear heavily every time the shaft turns, making shaft fit poorly.
Friction fit, yes at lower end. Drill through the aluminium casting and the shaft end to put a pin (nail) in to hold it if it comes out easily. It does not have to look pretty, any pin will hold.
Thank you for the reply. That is what I was considering. Perhaps drilling a hole in the end of the shaft and tapping it and adding a screw. Thanks for the wonderful video.
Yes this was a great video I wish you to go into the motor and cleaning I have smoke or burn marks on my paint and the motor stinks everything appears to be running normal but it does stink and there are brown burn marks on the Finish thank you wrenchman55 at gmail.com
Thanks for your video. My mixer stopped rotating and revolving. I began taking it apart in order to access the worm gear follower. When I took this gear off the shaft the PLANETARY fell down. Inside the planetary was what looked like a birds nest of aluminum shavings. It appears that some part of the planetary was coming into contact with bottom of the lower gear case every time I used it in the last 17 years. Have you ever encountered this? do you have any idea what caused it? I have images if you're interested. Thanks.
There has to be a washer or circlip keeping the gears away from the housing. It the soft washer wears away, the housing will be destroyed in no time. If some of the shavings are magnetic, that's the steel washer. If no steel is found, there may have never been a washer or circlip installed.
I put in Yamalube Marine grease. From boat repair. A high-temperature corrosive service environment grease. I figured kitchen = salt, soaps, cleaners and turning a propeller shaft or a heavy boat is like churning dough or grinding meat, a high torque situation.

Glad it helped
exelente maestro no entiendo el ingles pero las imagenes valen mas ke mil palabras saludos desde venezuela y ke tipo de grasa usan esas maquinas
Thanks
I see where you get your name! interesting - thanks!

Nice video, Do you know of any good place online to buy parts from?
Thanks
Not really, any and all you find wil be made in China, get the cheapest

Of course, excessive clearances are not good. Each to their budget, parts involved are shown.

What`s the video`s time frame on that detail?

I have another motor brush replacement, essentially the same idea: ua-cam.com/video/9EHQJDhxZc0/v-deo.html
What hold the main shaft in the bushing? Is it just friction? Mine seems to want to fall out.

Here is the inside of a similar motor. Pull it apart, clean the commutator gaps, ...ua-cam.com/users/edit?o=U&video_id=9EHQJDhxZc0
