KSM150-1 KitchenAid Mixer - Instructions

Rather than duplicate previous repair works, I recommend going to this user site and follow their instructions: http://www.neilcrockett.com/mixer1.htm. Once you have done this repair, taking the unit apart is easier to perform this tasks. Order replacement Grease "Benalene 930-2" in the 3.3 oz container and be sure to use the full container to lather all around all the gear components so grease will be available to units for years to come due to heat build up under load. Too, the 3.5 oz container is made for one unit repair job and is available through Amazon. This grease is available on larger quantities if needed / desired. I did order both, a Worm Gear and the Worm Gear and Bracket as I wasn't sure of my mechanical ability to make this repair until I got inside the unit but the worm gear is easily replaced once you clean out all the old grease. The worm gear is a neoprene type gear with all other gears being metal. I assume neoprene is used as sacrificial to save other gears from breaking under loads and years of use.

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.

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

watched an internet video to see what to do. Unfortunately even after replacing the chip the mixer it still didn't work.

Follow a YouTube video step by step

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.

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.

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

Watched a YouTube video to disassemble,from there went smoothly. One small piece of advice,take pictures with your smart phone during the process. Makes remembering easier.

Fairly easy if you have done it once before.

Skewer the screw in with my fingers,

disassembled replaced part reassembled now works well

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!
