3KSM150PSTDR5 KitchenAid Mixer - Instructions

I watched the video twice and made the repairs

it was a kitchen aid dough mixer, had to take the top portion off and replace the assembly with a new one that holds the teflon gear. You can purchace the gear only and it becomes less expensive, but at the time I didn't take the chance cause the greese was there and didn't want to take a chance. Its a simple repair by removing some cotter pins and phillips head screws.

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.

Per a video on this site, I removed the stand part, then removed the rear electrical cover and aluminum band which wraps around the mixer. Next, remove the drip ring and planetary gear (use a punch). Then remove the 4 screws securing the bottom housing and the 5 screws around the planetary gear housing. You should be able to pull the upper and bottom housings apart now. This exposes the control lever. Just unscrew it and replace it. Re-install all parts in reverse order.

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.

The knob was attached to the new lever. I began to disassemble the mixer case so that I could replace the lever. However, it soon became apparent that this would be a major project involving many components and potential problems in getting the unit back together. Since all I wanted was to replace the knob, I simply knocked it off the new lever and forced it onto the old one. It is hard for me to understand why Kitchenaid would not make just the knob available.

Repair was easy. Remove the seal ring with a flat blade screwdriver and drive out retaining pin. Pry out lower unit using two screwdrivers, one on each side. Once apart, use spring clip pliers to remove snap ring. Pull out shaft and replace. Clean and lubricate as you reassemble in reverse. Google the model number to get detailed instructions.

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.

Thank you

Knob fell out of the front of the mixer into the bowl and jammed the beater. This caused the motor to strip the plastic worm gear. Open unit to investigate and found about 4 teeth missing out of the worm gear. Ordered a replacement. Installed the new gear once received in about 30 minutes. Wife is now happy again. Just need to make sure you pack enough gease into the new gear before reassembling the unit.

I dismantled the machine to find the problem and to see what part I needed. Than when I ordered the part I saw the video of how to do it. If I had seen the video before I dismantled, I would have save a few steps. The video was very complete and accurate even it being an older model

removed one screw from back cover, loosened two screws holding speed control plate, removed one wire at a time from old unit to new, screwed two top screws back on mixer,plug mixer back in, adjust speed control screws until I reached correct speed, put back cover back on

Replaced gears and cleaned and re-greased gears

Unscrewed 3 Philips screws. Pried out the old screw cap. It had been there for 25 years and had flour, egg, etc. build up over the years. Did use a needle nose plier to lift it out. Put in the new one. Needed a rubber mallet to snug it down. Design has changed slightly over the years. Put the 3 screws back in and as they say in England, "you have an uncle named Bob."
