4K45SS7WH0 KitchenAid Mixer - Instructions

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

Unscrewed old Screw Cap, tapped it out with hammer. Replaced with new screw cap that was slightly different and tight. Tapped it in with piece of wood over it and hammered it on. No problems.

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!

I followed the instructional video linked to my email order confirmation. Partselect provided one of the best how-to videos I've ever seen. With the right tools, a little patience and the video, I had an outstanding repair experience.

disassembled replaced part reassembled now works well

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

I did some research and evaluated a modern day Kitchen Aid Mixer. Looked a the wire diagram and found out what items I needed. Ordered them from Partselect. Overall Mixer is updated and running. I made up some cookie dough with it. The Project took a few evenings due to rewiring the coils on the motor/armature and modifying the rear bearing bracket to hold the Phase control board (not OEM on 70's mixers). Then put it back together and adjusted the speed control.

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

Easy

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

just as the you tube instructions said.

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

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.
