This repair kit, despite being made in China, has excellent quality. Since the great majority of the Kitchenaid mixer problem was cause by the wear and tear of the gears so this kit is likely to solve your problem. The greatest challenge is perhaps to find a good instruction video on Youtube. Removing all the gunks/grease is not much fun but that is the extent of the difficulty. The steps afterward is quite straight forward. There are a total of four replacement gears. Use the plier to remove the snap-on ring and remove the top gear on the main shaft. Once done, push out the pin on the shaft to remove the bottom gear. This gear has a super tight fit and can be difficult to remove. I used a large screw driver to leverage against the gear housing to lift it. Once you remove all gears, clean up thoroughly before install the gear back since there may be shredded metal pieces inside the gunk. Overall, this kit is one of my best investment since a new Professional 600 cost nearly $800. I spent about an hour fixing it and the majority of this time is spent removing the grease. Those who gave it less than 3 stars may not fully get the hang of it or simply had bad luck.Considering its price, the deal is unbeatable.

I purchased this kit to update some of the parts in my mixer. I didn't use the whole kit but rather found myself using parts from 2 different ones. I used the drive gear (for attachements because I noticed my old one was worn. I also used some of the grease but here again I also used grease from another kit. It really made a difference quieting down the mixer since it was about 40 years old and I had never cleaned out the old grease.

This kit had almost everything I needed. It was actually fairly easy to install and now my mixer should be good for another 10 years.Only a couple small things kept it from being a five-star review.First, the snap ring pliers that it came with had studs on them that were too thick to actually use to remove the snap ring from my machine. This resulted in me having to pry it off with a screwdriver and ruining the existing ring. Luckily I was able to find one for 50 cents at my local hardware store.Second, this kit really should come with the snap ring as well.

I bought this for routine maintenance on a professional 600. After installing all included parts, the mixer had a loud rattle which increased in frequency when the motor was sped up. I spent A LOT of time rechecking the parts install including runner the motor with the gears installed just to check that the motor wasn’t faulty. I ultimately re-installed all of the original gears and the mixer immediately ran with no abnormal noise. I did notice the gear provided that sits below the bevel gear has way too much play on the shaft that it attaches to ( original gear needed a small mallet to remove and eventually reinstall). Cheap machined gears caused a lot headache and I should have just bought Kitchen Aid branded parts. Wish I could get my money and time back.

I bought a KitchenAid mixer online that needed fixed, so I figured out what I needed and this worked great. With a mixer that is used regularly it has held up well. Easy to install.

Great tool set

Worked for a few weeks then started making horrible noise. Looking for a better alternative.

This was just what the doctor ordered. My husband had the gears replaced in no time and my kitchen aide mixer is working great. Saved a few hundred by not sending it in to the service center.
