The appliances belong to my neighbor who had no papers/manuals so I was on my own to figure out how to even get the machine apart and to find the correct nomenclature for the parts I needed. The PartSelect diagrams on the web site told me everything I needed to know. The key to the dis-assembly was the band around the center of the machine. After I discovered that, the band came off easily followed by splitting of the casing. One the first machine it appeared that the circuit board/switch assembly was in bad shape looking like it had been over heated at one time. As a test, I took the electric component out of the machine that would run and put it on the dead mixer. Beauty, it worked. OK so much for the easy one. On the machine that would only turn part way, I split the transmission housing by removing four small bolts and found that the worm gear was partially stripped. So, I ordered a new gear, switch assembly and transmission gasket since the old one was torn during my dis-assembly process. I don't have any snap ring pliers, so the snap ring(retaining ring) was taken off using a large screw driver and a a pair of slip joint pliers. Worked well, but I was afraid that the old retaining ring may have been damaged, so I ordered a new one. Good idea, since I broke the old one trying to put it back on. When all of the parts were installed, I filled the voids with heavy grease and put it all back together. Both mixers now work perfectly which saved the owners several hundred dollars. They had planned on replacing them both for use at their restaurant. I am now a fan of PartSelect because of the ease at which I, a novice had been able to find and get the correct parts, and the speed at which they arrived. I am also very impressed with the Kitchen Aid mixers because it appears the they are very well made, and are easily repaired if they do break. I was surprised to find a small appliance that is repairable. Many are now just throw away quality. I am a hero to my neighbors (they don't know how easy this was) and will keep the refrigerator magnet that was included with my parts order, for future repairs.
