is wear on the worm gear obvious ? KitchenAid Artisan Mixer
For model number 4ksm150pswh
Fix.com logo
Hi Norm, thank you for the question! Sadly, any component within the machine is going to wear down from constant use. Worm gears are used constantly at high speed so they are more likely to wear. We hope this information helps!

Should wear be visible on an expected faulty worm gear ? Mine looks normal but an unsure if that is deceptive !
For model number 4ksm150pswh
Fix.com logo
Hi Norm, thank you for reaching out. According to our research, you may be able to see the wear on the worm gear as the teeth may become rough and no longer uniform in shape for a worn-out worm gear. We hope this information helps!

stripped the worm gear, fixed bushings
I opened the mixer and determined that the worm gear had failed, as designed, to save the other gears. There was also oil separated from the grease and it needed replaced. The Transmission case gasket was damaged and must have been from the time it was built. I removed the grease with putty knife and kept I on a plastic plate until the pa rts came in (to determine the amount needed when I replaced it.) I used the punch to remove the two pins needed with light tap from hammer. I left the mixer in pieces on the counter until the parts arrived. I replaced the gear and all other parts and placed fresh grease in the mixer. I had to adjust the beater, too. I had removed one of the bushings by mistake. When mixer was back together it would not start. IT TOOK SOME TIME BUT I FOUND ANOTHER WEB SITE THAT EXPLAINED HOW TO REPLACE THE BUSHING. TAKE A FLASHLIGHT AND LOOK INTO THE SQUARE BRUSH HOLDER. THERE IS A DETANT IN THE HOLDER. THE SHAVED SIDE OF THE BRUSH NEEDS TO SLIP PAST THE DETENT TO BE ABLE TO TOUCH THE AMATURE. Once that was done, it worked great. Very smooth with new gear and grease.

Internal Worm Gear to Electric Motor Stripped
After looking at your sites great exploded views I was able to disassemble the motor assembly. Replaced the brushes and damaged gear assembly . Reassembled Worked great.Wife's china made mixer had diecast internal parts that shattered after her attempt to mix cookie dough. Now with this USA made Kitchen Aid Mixer she can mix concrete wit h coke bottles and never work hard. Thank You for you great site and delivery ethic. Only wish my Hitachi ex50urg excavator had a parts exploded views as you do. Also Worm gear and bracket had improvements to redirect lube grease to keep improved gear material well lubricated.

Powers on monentarily at lowest speed. No other speeds work.
Primary problem was a bad speed control plate (SCP). I removed the rear cap exposing the speed control plate and pressed the adjustment screw while I changed speeds. It started working but saw sparking on the SCP contacts. Decided to first change out the worm gear & grease. 3 oz container of grease is avialable from Amazon. Don't buy the 1# pkg. You'll end up tossing most of it out. Contrary to other posts you must use food-safe grease, in case a leak develops, which was the case here. New control plate arrived damaged but the site replaced it promptly. Plate is labeled with wire colors but hard to read in dim light. Suggest drawing a diagram of the wire colors & placement before disconnecting. Also spent extra time adjusting the 3 screws on the plate so the mixer operated smoothly at all speeds. Rubber foot was much smaller & taller than the others and caused the mixer to rock slightly. Trimmed off the top and it worked fine.

KitchenAid stand mixer won't spin - broken worm gear
During our seasonal baking our stand mixer quit spinning putting a quick halt to the process. The mixer was only about 9 years old and i figured that it was a goner. I did an internet search and was planning to go to Walmart the next morning and spend $280 on a new model but after looking at the unit and doing a YOUTUBE search I followed some easy directions to take the unit apart and replace the worm gear. The hardest part of fixing the unit is getting to the gear which is caked with grease. Moving the gear grease out of the way is somewhat of a challenge since it is very thick similar to wheel bearing grease on your car. Once i got to the gear and removed it i could see that there were some missing teeth. The gear is made of plastic and designed to give if too much pressure is put on the motor and other gears. It saves the motor from burning out. Again, doing an online search i found that this site had it for under $5 so I ordered it. I had to wait a few days to receive it but once it came in the repair was simple. A failing worm gear is a common problem so I decided to get two gears so next time i will have one on hand for an even quicker fix. Upon reassembly I had to clear some more grease out of the way to tap out the retainer key that held the gear in place. Once done the repair was quick! Do this...it is easy if you have a few tools and a little bit of common sense!

worm gear had worn the teeth down where the mixer would not turn anymore
Removed the band around the end near where the beaters go, then remove the 4 screws holding the case together, then removed the screw holding the end cap over the motor area, then removed 6 screws from near the beaters area. Next, pulled the case apart to get to the worm gear. Remove 3 screws from the worm gear case, then took a hammer a n punch and punched the pin holding the worm gear assembly together out, removed the worm gear and replaced and then did all the first steps in reverse order.

seems fine so far
fit just fine, seems good so far, but it has only been used a couple of times. Visually it is different than displayed, the "plastic" gear part is black so it doesn't look like the original that it replaced. Time will tell if my review is accurate.
