After I dropped a part of the shield into my mixer the motor screamed and I unplugged the mixer. I found out I had a broken worm gear. I then order the part and per the helpful video I did the repair and I also changed the brushes my mixer is up and running waiting for the holiday baking season thanks to Part select.com Very easy Instructions to follow I am very happy with the results. Thanks Barbara
The worm gear driven by the motor stripped due to excessive load.
Remove the mixer head from the base by removing the 4 Phillips head screws. Pry off the ring around the rotating part with a flat head screwdriver. Punch out the pin holding the rotating part and remove. Remove the trim strip by removing the two Phillips screws at the rear of the unit. Remove the 4 screws at the bottom of the mixer head. Carefully separate the bottom of the head from the top using a flat screw driver. There will be the power wires connecting the top to the bottom of the unit. It is best to disconnect these wires to avoid breaking them during rest of the procedure. There will be a lot of grease in the gear box of the mixer. The assembly holding the damaged worm gear can now be removed by removing the three screws holding it to the bottom of the mixer head. At this point I removed the grease from the worm gear assembly to allow better inspection. Punch out the pin holding the worm gear to its shaft and remove the shaft. The worm gear is now free and can be replaced. Add some extra grease to the new gear and reassemble the mixer in the reverse order.
I discovered the brushes were worn, and one side had broken off and lodged against the armature.I got lucky as I removed the brush caps and the sleeves the brushes fit into (simple job) and was able to hand turn the armature so the pieces fell down into the bottom of the mixer housing.After removing them, I replaced the brushes and the mixer runs like new. Thanks for the fast delivery AND more importantly, the right part. Steve
the plastic covering the thumb screw cracked almost half way and lost the piece....so the new one is being used to replace this old one...very easy to install
The brushes on the inside of the motor were destroyed. We thought that it would be easier to just replace the brush holder and the brushes, however, the brushes were easy! and QUICK! The brush holders...not so much. We had lots of problems getting the brush holders into place because of a metal piece that had to fit perfectly on top of the brush holder. It made it easier when I held the mixer upside down (we dissembled it) and my husband did his magic on fixing the brush holders. Pray that you won't need to replace the brush holders because it was NO FUN...but the brushes were QUICK AND EASY :)
I was very happy with the customer services department and the support I received in identifying the part I needed for the repair. I received an email confirming my order with all details. I do wish you had a more cost effective shipping alternative, like Priority mail. The repair went well and the mixer is back in business, for making those Chocolate Chip Cookie and brownies if you know what I mean.
I how the video for replacing the worm gear on your website. It help me a lot. I followed step by step instruction display on video. It was great help.
