KSM88PSQ2CB0 KitchenAid Mixer - Instructions

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

Skewer the screw in with my fingers,

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 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.

I just thought there had to be a way to replace a component to correct the speed problem. I've never worked on a mixer before, so I thought it would be a challenge. Actually the repair was fairly easy. Make sure the unit is unplugged from AC. I removed the back motor cover with one screw and removed the end seal. I compared the parts on the mixer with the diagram provided at the Part Select website. I then ordered the parts. When the parts arrived 3 days later, I removed the Speed Control Plate ( 3 screws) and Phase Control Bd (1 screw) as one Assy. Removed the old Governor and slipped on the new one. Assy the new Speed Control Plate and Phase Control Bd comparing wiring and screwed them back to the unit. Removed the two motor bushes by unscrewing the side black motor brush holders and inserting the new brushes. I tried powering motor and nothing happened. I thought, great, now what did I do? I found out that you must make sure the brushes actually touch the armature otherwise the motor doesn't run. The gears are worn from grinding to much deer meat and my wife says no more. I've ordered new gears and looks like that job, too, will be easy to repair. Adding these parts is alot cheaper than buying a new unit and it will run like new. Not bad for over 10 years of usage.

Order the worm gear part number PS11748374.

I would recommend two people if possible.

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.

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.

The repair was easy only requiring a phillips head screw driver to remove the old screw cap. The new screw cap fit snuggly and required a little downward pressure from my hand to seat it. Then I simply tightened the screws. Good as new for this 30+ year old mixer. My wife loves this mixer that was given to her by her Aunt. Glad we could keep it going.

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

Just put on the new whip...exactly like old one.

I removed three screws, pulled off the old base plate.
Put new base plate in place and replaced the screws

Easy

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

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.
