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.
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!
I watched a YouTube video all the way through, then watched each segment and followed along with the video. It was messier than the professional repair guy, but it worked out fine. This is not a difficult repair when you can watch a video and follow along. It saved me about $130.
Decorative plug at top of mixer fell into the bowl and jammed the mixer stripping gears
Watch U Tube video. Take care to keep track of disassembly. Hard part was to have 4 types of screw drivers to fit the different screw heads. Be sure to clean broken gear clogs out of the grease. Parts select lady was a great help. Download Parts select diagram for extra help. Time and patience!
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!
The brushes are located on each side of the tilt head of the mixer. I used a screwdriver to remove the screws, removed the brushes & replaced with the new ones. Runs great again!!
First i went to the Kitchen Aid web site and found a video on how to take a part the mixer. Followed the instructions from the video and it was very easy. The grease in the machine was black so i cleaned it out of the transmission and repack it with hi-heat wheel bearing grease that i got from a auto parts store it took about a 1/2 lb. then put the gasket in and back together and put the o-ring on. Have run for awhile and it is ok. Want to say that these are very well built machine.
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.
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!
