I actually didn't do the repair. I asked a friend who was a carpenter about what he thought was wrong with my mixer since it only had high speed which made mixing flour a snow storm. He said when his tools do that, it's the brushes. He ordered new ones and presto - my mixer works marvelously. He saved me from dumping a good mixer and $$$$$$$.

Once I looked at the schematic I was prtty sure what the problem was and what I needed to repair the problem. It was reltively easy to disassemble the mixer and immediately saw that I was correct in what was needed. I ordered the parts. They came through with no delay. It took almost as long to find all of the parts as it was to do the repair. In all it took about a half hour to repair, put it together and clean everything up. It works just like new.

Looked up part replacement, ordered on line. Found part easily and waited anxiously for new part. I wanted to make cookies for the holiday season. Received part quickly, opened up packaging, put on mixer and I was back in business. Thanks so much for an easy fix. I also was pleasantly surprised at how cheap the replacement part was. Thank you, thank you for allowing me to get a new part with ease and continue to use my Kitchen Aid mixer.

Very messy as there is lots of heavy grease inside the mixer and you have to fish out the blown gear parts. I vary glad I took shop class in High school as it preped me for the job. The machanical drawing you provide were very useful but you should mention the grease.

Mixer works just like new. and I got the parts in two days with standard shipping. Pizza on Thursday and fixed by Saturday

My kitchenaid mixer is at least 37 years old. Everything has worked fine after all these years except the screw cap was flimsy, still stainless steel, but not sturdy. So I tried to replace it , but was told it was too old and couldn't get the part. I contacted Part Select and found a screw cap from newer models fit perfectly and should outlast me and the mixer, it is a lot sturdier than original one. It also arrived in 2 days, which was fantastic. Thanks guys
