KSM180LELB5 KitchenAid Mixer - Instructions

After stalling the mixer while mixing dough I found that the motor still functioned but the blade didn't move. I basically took the mixer into my shop along with a digital camera to record any complicated disassembly procedure I might have to deal with for reassembly and proceeded to disassemble the mixer. Once apart, I cleaned the mixer parts, removed the broken worm gear and bracket, and got online for someone that carried the replacement piece. PartSelect sent the replacement within 3 days and now it works great again.

I removed the decorative band that covers the seam by removing 1 screw. I then removed the top portion of mixer by removing 4 square head screws. You will then see the gear housing in the front of the mixer. Remove the 4 screws holding that on. There are no spring that are going to pop out and you never know where they went, but be careful because there is a lot of grease and a gear that it just laying in there on the right side. You will see the stainless shaft with a couple on gear cogs on it. Remove the retaing spring from the shaft and pull the top gear off, it may be a little snug. You will then see the dowel pin, mine was sheared off but I could see where it was. Be sure to remove the broken pieces. Use the punch to knock out the remaining pin. Replace with new pin making sure it is evenly exposed on both side of the shaft. Replace the top gear, then the retaining spring, the the gear housing cover, then the mixer top cover and finally the decorative band. Be sure to unplug before you start. These mixers are expensive and expensive to have someone fix them. I ordered 2 pins because shipping is a little high and the pin is cheap. I fixed this for $17.00 total and have a spare pin.

When I took the back cover off I found two parts that "could" be the problem. The speed control plate was cracked which explained the spotty working. I ordered both parts and installed them very easily. The parts fit perfectly and resulted in the mixer working perfectly. I can't say enough about the excellent parts. They were perfect.

dissassembled mixer and replaced gear

To access the interior of the mixer, I first removed the single screw holding the cup-shaped part at the rear. Then I removed the 4 large screws on the under surface of the mixer head. Next I removed the bright metal ring around the planetary gear area by prying it off. I then pried the dish-shaped part off the shaft using a large-bladed screwdriver. This exposed 5 screws on the circumference of the planetary gear. By removing them, one can pull up the gears and see into the area below. I found the worm gear had fractured. By removing 3 screws at the base I extracted it for closer inspection, checking for any loose pieces. Beware of the jelly-like grease. The replacement part goes into position, and one then follows the steps in reverse.

I followed the video provided online. The model shown was not exactly the same as mine, but very close. The step-wise progression demonstrated on the video helped a lot. I had to double check the video a couple of times which added to the work time....I could probably do it again without the video in under 1 hour. As shown in the video, I laid out an old towel across two pieces of 2x4 which helped keep the mixer head in a position that was easy to work on and also prevented scratches.

Easy removal of old screw cap, but new one didn't just drop in. Had to scrape paint and a little aluminum to make it fit. Finally did, and it works fine now.

followed the instruction on you tube

I took out the worm gear and replaced it with the new one. It is important to have the correct punches that are just under the diameter of the pins.

Took the mixer down to the gear box. Found the plastic drive gear had a few stripped teeth. Did a search on the internet for the mixer gear. Found a couple of suppliers. Ordered the needed gear, pin and a bearing block just in case it was worn. The bearing block did not need to be replaced. Cleaned the broken off teeth from the gear grease and put the mixer back together. All worked fine when I plugged it in.

I found a video on how to repair mixer that would not turn. Watched video several times and replaced worn worm gear. Getting the old worm gear was the most difficult part of the job. I had to go purchase a pin punch ($5.50) with the correct tool is was easy.

Unscrew and dismounted the mixer, gather all pieces and screws, cleaned and washed every part, took away the old grease and replaced it with a new one, also looked carefully for the lost teeth and found them, Put grease in every part, put back and screwed all the pieces of the mixer, then tried the mixer which worked really well.

Followed up by your précised video, and print copy's which helped me a lot. That's easy!

Followed directions video on line. good directions.

I watched the video twice and made the repairs
