The threads on the plate that holds the bowl had stripped and the bowl flew off when mixing
Removed old plate, screwed in new plate and works like new! Was so happy I wouldn’t have to replace my 30 year old mixer.

The original screw cap would not hold the mixer bowl in place anymore.
The new part was too large for the replacement job, but we used the self tapping screws that came with the mixer and screwed them in from the bottom to open the holes a little more since the original screws were to short to hold the new plate. Then we replaced the screws with longer screws and that seemed to do the trick!

Stuck agitator shaft and dough hook
I had a sourdough batch get into the space where dough hook attaches and it got so stuck that nothing - not hot water baths, not pliers and screwdrivers got the dough hook released. I had to open up the mixer following partselect you tube instructions and replacing the parts. What was confusing to me at first is that my 45 year old mixer had an extra screw on top of the shaft that no longer is there for newer models. It took me longer than I am willing to admit to figure that the extra screw is not the result of me skimming the instructions - the original shaft and dough hook went to a friend who broke it attempting to disengage the two parts (the dough turned out to be a very strong form of glue!). The piece is working like new. I preferred the agitator shaft with a spring to hold the end piece tighter, but the new set up without a spring works just fine.

Worm gear was stripped and needed to be replaced
I am not handy, but was able to follow this YouTube video and do this repair easily and successfully: https://www.youtube.com/watch?v=1QsgPIL9FpA

I did take the mixer apart first to verify that the worm gear was the issue, then ordered the part from you site. I received it quickly and was able to do the repair and get back to mixing in a few days!

The mixer broke the worm gear(the only plastic gear inside the mixer) and needed replaced.
I took apart the mixer housing and removed all the screws. The most difficult part was the two pins that needed to be removed with a metal punch. They were in fairly tight. The mixer came apart pretty easily and it was obvious which part needed to be replaced as it was broken and missing teeth. After replacing the gear and applying new grease for smooth operation, I simply put it back together and it has worked like new ever since.

No rotation on mixer
You tube has great instructions! I would suggest when you buy a part to let customer know that they need a food grade gear grease ordered to complete the reinstall of all gears and body parts!

The mixer would not operate so I took out the brushes. Work afterwards but was a little noisy so, considering the advanced age of the machine and after doing research, I decided to replace the worm gear and bracket.
I followed the instructional video linked to my email order confirmation. Partselect provided one of the best how-to videos I've ever seen. With the right tools, a little patience and the video, I had an outstanding repair experience.

The mixer was given to my wife. Sometimes it would work or not.
When I took the back cover off I found two parts that "could" be the problem. The speed control plate was cracked which explained the spotty working. I ordered both parts and installed them very easily. The parts fit perfectly and resulted in the mixer working perfectly. I can't say enough about the excellent parts. They were perfect.

Attachment hub stopped spinning
Used youtube movies to disassemble the mixer and found that the gear was stripped. I kept the screws in labeled ziploc baggies so I wouldn't forget which screws went where. Once the part arrived, it was very simple to replace the gear. I regreased the mixer and then reassembled. The trickiest part was how greasy everything was! It was also hard to get the pin through the beater hub - I found a video that suggested using a very slim screwdriver to thread the hole before inserting the pin. This was the most involved part replacement I've done on my own, and it was very satisfying to get my mixer back in working order!

stripped worm gear
i disassembled the mixer until i could remove the worm gear; is in a housing that that includes another gear and shaft. make sure you have a magnetic tray to put parts in as you work or you will spend more time looking for parts than reassembling the mixer. once you have the gear housing out you will need a small diameter punch to drive out the pin that holds the gears in the housing(i used a 5/32 transfer punch.) make sure you punch the pin out where it will be caught or you will need to order that part because you will not find it. after knocking the pin out it is just a matter of removing the old gear, putting the new one in, and reversing the steps and getting everything reassembled.
