KSM450BK0 KitchenAid Mixer - Instructions

Replaced the speed control plate and phase control board and works well. Pay attention to speed control board spring and adjustment lever when reassembling.

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!

Was able to use the diagrams to figure out how to put everything back together. Would have been a nightmare without that as I took the thing apart without really paying attention to what went where. The hardest part was inserting a set pin that holds the Bowl lift arm, which fits inside the stand. in place. So new parts - $20, less than an hour of my time disassembling/reassembling, probably saved me $125 in repair plus a couple hours driving it to service place and picking it up. No brainer.

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.

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!

I removed the spring loaded brush screw on the side of my mixer and lost it the next day. I found a schematic of this part on your website and ordered the four pieces that make up the brush screw(?). They arrived in just a few days and I referred back to the schematic to put it together. I then popped it in my mixer, screwed it down, plugged her in and away we go! Easiest repair I’ve ever done! I’m a 70 year old retired lady and not very handy, but this was an easy fix! Thank you, PartSelect!

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

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

Skewer the screw in with my fingers,

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.

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

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.
