4KSM50POB0 KitchenAid Mixer - Instructions

removed old screws and latch, replaced it with the new. took just a few seconds. This is the first time i ever fixed anything. customer service was amazing

I removed one screw on back, once inside mixer I removed the ground screw then pulled off the black and white push on caps, then I reversed everything to get it installed, very easy

While kneading dough, my 27-yo stand mixer walked off the counter, and shortly thereafter the plastic bowl lift arm piece broke. After a quick internet search I ordered the part. Installation was extremely easy. 1) Using a rachet with a #3 Phillips head bit, remove the four screws holding the motor to the base. 2) Using the Roll Pin Punch pop out the roll pin. 3) Loosen and remove the cotter pin with the screwdriver and pliers. 4) Remove the broken piece. 5) Attach the replacement piece to the handle and insert the roll pin, tapping into place with the Roll Pin Punch. 5) Attach the lift arm to the piece and fix with the cotter pin. 6) Reattach the motor to the base. Ready for 27 more years of stand mixing duty!

Used the diagram on the website and a video
Totally worked!

disasembled found stripped gesr assembly ordered and replaced went very smoothly. It would have been good to have info and acsess to the correct gear grease to use in a mixer / food grade but it worked out well anyway.shipping was very fast thanks

just as the you tube instructions said.

Disassembled gear housing and replaced worm gear/bracket assembly. The hardest part was cleaning and working around what looked like 2 pound of grease. I will contact you again if I need parts for anything. Thanks.

Followed the repair instructions from the manual. ...

I did notice that the replacement part had an extension on it that allowed for the gear grease to be "pulled up" onto the drive gear ( the one that broke), while the unit is running. This feature was not on the original part, but was obviously an upgrade design which was added after my particular mixer was made. I think that the extension on the bracket will help prevent the new nylon gear from binding and stripping as we use the mixer from now on.

I'm glad that PartSelect had the more modern part on hand, and not just an "overstock" from the original, inferior design.

Easily took apart and replaced gears. thanks

The insertion part of the foot was tapered to fit in the hole in the mixer. Simple pressure was not the answer. So I used a small key, placed it on the bottom of the foot, after applying a little vegetable oil on the foot, and tapped it into place. Worked well.Joe

dis-assemble, replace part, re-lube, reassemble, test good.

replaced worm gear and wonderd why they used plastic instead of a stronger metal gear, unit works fine

We simply replaced the gear with the new one. It was very easy to install.

I did exactly what the PartSelect video demonstrated after watching other DIY videos on the Internet, thus I did not remove the stand which seemed like a little too much for a simple straight forward repair. This is the second time I have replaced this gear. The first time was about 10 years ago when the bakelite gear broke on a 30 year old KitchenAid K
-45. That mixer made hundreds of loaves of bread after grinding many pounds of wheat berries. The only reason we had to replace it was that it walked off the flour dusted counter and landed on its head when my wife had her back turned. Otherwise we would still be using it. :-)
Thanks for the excellent service and instructions.

Dismantled the mixer, took photos, and re-assembled unit.
