5KSM150PSBLT4 KitchenAid Mixer - Instructions

Replaced it with a new part. No installation or repair to maching was necessary

I was very happy with the customer services department and the support I received in identifying the part I needed for the repair. I received an email confirming my order with all details. I do wish you had a more cost effective shipping alternative, like Priority mail.
The repair went well and the mixer is back in business, for making those Chocolate Chip Cookie and brownies if you know what I mean.

Thank you

Placed pin in the hole...some wiggling had to be done for a tight fit. Installation complete!

I how the video for replacing the worm gear on your website. It help me a lot. I followed step by step instruction display on video. It was great help.

Followed directions video on line. good directions.

The plastic worm gear was stripped,I took it apart first then cleaned out all the old grease so when the new part came it together like a charm.

Initially I thought this was due to worn motor brushes. I replaced the brushes but it did not fix the problem. Stator tested OK with an ohmmeter so I figured it was the armature part #PS3651001. Ordered that next and that fixed the problem. Spent 25 dollars which beats buying a new one. Next time I'm buying a used one from the 60s or 70s when they made them better! One tip - I had a hard time removing the pin that you need to remove the helical gear. Heating it with a heat gun helped a lot, also helped with replacing it after.

Followed up by your précised video, and print copy's which helped me a lot. That's easy!

Unscrewed 3 Philips screws. Pried out the old screw cap. It had been there for 25 years and had flour, egg, etc. build up over the years. Did use a needle nose plier to lift it out. Put in the new one. Needed a rubber mallet to snug it down. Design has changed slightly over the years. Put the 3 screws back in and as they say in England, "you have an uncle named Bob."

Just screwed it in

I removed the screws on the back and base of the mixer. Took off the retaining ring and screws holding the mixer beater bar. Tapped out the retaining pin using an allen wrench and hammer. Carefully as not to scratch the unit. Removed the old grease, the screws holding in the worn worm gear. Replaced the gear, re-greased and reassembled the unit. To line up the retaining pin I used a very small allen wrench to get through the hole as it needed to set down all the way. Then when I wiggled it down it lined up the hole for the retaining pin. I tapped the pin back in place with the hammer and a larger allen wrench. Replaced the screws, lightly greased the gears. I had taken the "brushes" out earlier and learned that they go in a certain way. I also learned that the screw at the back by the wires, by adjusting it tighter or looser controls the speed lever. If your mixer won't work on low speed the screw has to be adjusted!

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

Put on a new base plate using fresh screws, all ordered on Parts Select in under a minute. Now my grandmas old Kitchen Aid Stand-up mixer is as good as new! This was way easier than I thought it would be and really a great experience!

remove 3 screws ,remove old sanding disc replace with new installl screws

Open the package with the new screw and it looked like the screw was wider. I tried it to see if it goes in and as long as you screw it straight in, there was no problem.
