I followed these video instructions. Note: you will need the roll punch as a substitute will not work. Also, use the punch before removing the stand base as this will make it easier to keep it stable.

I disassembled the mixer as shown in the online video & replaced the part which was attached with 3 screws. The noise is gone & my wife is happy! And, I am happy that we did not need to spend hundreds for a new mixer. I would recommend that if you think that this part will fix your problem, that you replace the entire worm gear & brack ...

Remove the pin joining the planetary (the rotating piece) to the shaft using a punch and hammer. Then pull the planetary off of the shaft by rotating back and forth while exerting downward pressure. Remove all screws (9) holding the halves together. Loosen the power cord from the rear slot and carefully lift and remove the upper half turn ... Read more ing it upside down. Remove and replace the gear assembly and remove and replace all grease with food-based lubricant. Replace gasket if necessary. Oil motor and linkages. Adjust planetary speed, using the lowest middle screw on the rear panel, to 60 rpm at the number one position. Reassemble. Clean, polish and touch-up.

I watched a 3 part U-tube video. Part 1 take it apart. Part 2 grease it and replace the worm gear. Part 3 put it back together

Found plastic worm gear stripped. Ordered part from excellent parts breakdown sheet provided by this site . Looked up above model mixer on U Tube and watched video on "How to repair KitchenAid Mixers. Thanks to this site for prompt shipping.

My mixer was a heavy-duty, so the stand is stationary (doesn't flip up like the video's all show). After trying for about 30 minutes to figure out how to get the top off to expose the gear (about step 5), I finally took out the large screws that connected the base to the top (just under the top section, and found that underneath that pla ...

After putting the two halves back together, BE SURE TO TURN THE GEAR UNTIL THE HALVES SETTLE ALL THE WAY BACK INTO PLACE. Mine nested in, but was off about 1/16 - 1/8" so I couldn't get the pin back in. I finally put the hole punch in the hole and jiggled it a little bit and it settled in the last 1/8" so that I could put the pin back in. Easy, peasy from there! :)

This is a relatively easy repair. There are a number of steps to getting access to the gear and bracket but easy to figure out. Once the assembly is opened up the gear bracket is exposed and three screws removes it and reinstalls the new piece. Once it is exposed I recommend cleaning the inside of all the old grease and putting fresh i ... Read more n. I also recommend replacing the Transmission Case Gasket. Both can be purchased from this site. Then reassemble. Prior to putting the back housing piece on, which is the one of the last pieces take a few minutes to look on uTube for instructions on how adjust the speeds of the mixer. This is also very simple and frankly shouldn't be overlooked. Many mixers seem to loose "speeds" over time. A tune up repairs all the presets so the mixer is running at the appropriate speeds and all the speeds. Mine seemed to not have two of the speeds, and initially I thought I had lost some gears. But a tune up restored them.

followed the instructions and video on web site and it went very well. Repaired two in the last 10 days and both went as planned with no issues. Great site, service, and instructions. Will use them again.
