4KPD1620T2 KitchenAid Mixer - Instructions

i disassembled the mixer until i could remove the worm gear; is in a housing that that includes another gear and shaft. make sure you have a magnetic tray to put parts in as you work or you will spend more time looking for parts than reassembling the mixer. once you have the gear housing out you will need a small diameter punch to drive out the pin that holds the gears in the housing(i used a 5/32 transfer punch.) make sure you punch the pin out where it will be caught or you will need to order that part because you will not find it. after knocking the pin out it is just a matter of removing the old gear, putting the new one in, and reversing the steps and getting everything reassembled.

I screwed the two screws into the place of original holes and Voila! it was repaired.

Skewer the screw in with my fingers,

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

First of all I found the part in no time flat and ordered it early afternoon and it was at my door within 24 hours! My son was off work one day and I asked him if he needed a job to do and he said "sure". So I showed him the new part and where it goes and in less then 10 min it was working. awesome!

Removed the two screws that hold the bowl spring in place. Removed broken spring. Replaced broken spring with replacement spring. Tightened two screws that hold it in place.

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

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

I rip everything apart and put new and grease it. works like a new one.

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

just as the you tube instructions said.

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

Easily took apart and replaced gears. 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.

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.
