3KSM150PSTGA0 KitchenAid Mixer - Instructions

After stalling the mixer while mixing dough I found that the motor still functioned but the blade didn't move. I basically took the mixer into my shop along with a digital camera to record any complicated disassembly procedure I might have to deal with for reassembly and proceeded to disassemble the mixer. Once apart, I cleaned the mixer parts, removed the broken worm gear and bracket, and got online for someone that carried the replacement piece. PartSelect sent the replacement within 3 days and now it works great again.

To access the interior of the mixer, I first removed the single screw holding the cup-shaped part at the rear. Then I removed the 4 large screws on the under surface of the mixer head. Next I removed the bright metal ring around the planetary gear area by prying it off. I then pried the dish-shaped part off the shaft using a large-bladed screwdriver. This exposed 5 screws on the circumference of the planetary gear. By removing them, one can pull up the gears and see into the area below. I found the worm gear had fractured. By removing 3 screws at the base I extracted it for closer inspection, checking for any loose pieces. Beware of the jelly-like grease. The replacement part goes into position, and one then follows the steps in reverse.

dissassembled mixer and replaced gear

Dear Customer Service,

I just would like to express my gratitude for your wonderful service. I received my part for my Kitchen aide mixer on time as promised. The part fit perfectly. Thanks you PartSelect for being there.
What a Great Site!

A Happy Customer!

I followed the video provided online. The model shown was not exactly the same as mine, but very close. The step-wise progression demonstrated on the video helped a lot. I had to double check the video a couple of times which added to the work time....I could probably do it again without the video in under 1 hour. As shown in the video, I laid out an old towel across two pieces of 2x4 which helped keep the mixer head in a position that was easy to work on and also prevented scratches.

No nstallation required, simply attach.
Your website was the only one that made sense. I am blind and follow the instructions with a screen reader. I had no difficulty. It was much easier than this questionaire.

it just screw in.

I did not do the repair myself, however, I contacted a suggested service company which in turn was a company I had used before when I had problems with my JenAir microwave. Excellent service, prompt and very professional. Thank you JenAir for your assistance in providing promptly the parts needed to complete this job.

simply put it together, .

watched instruction video (from Part Select), the demonstration was close enough to enable me to repair the mixer. Newer mixers are disassembled differently.

Change brush's

Just change the motor brush. That's it! It work well now. Thank you, Partselect!

I replaced the brushes. I didn't realize that I've put one of them wrong. Reminder for next time the brushes have to touch the rotor of the motor. It took me a little bit to understand but the brushes can go in and not touch the rotor. It works very quietly now. Thank you PartSelect for your infos and knowledge.

Knob fell out of the front of the mixer into the bowl and jammed the beater. This caused the motor to strip the plastic worm gear. Open unit to investigate and found about 4 teeth missing out of the worm gear. Ordered a replacement. Installed the new gear once received in about 30 minutes. Wife is now happy again. Just need to make sure you pack enough gease into the new gear before reassembling the unit.

Opened beater , removed grease , took bearing off , removed alignment pins ,pulled shaft and pinion out , replaced parts , lubricated with new grease , assembled the whole drive . do not like the plastic gear or the clearance once assembled has a lot of slop for this type of drive .
