3KSM150PSTPA5 KitchenAid Mixer - Instructions

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

I dismantled the machine to find the problem and to see what part I needed. Than when I ordered the part I saw the video of how to do it. If I had seen the video before I dismantled, I would have save a few steps. The video was very complete and accurate even it being an older model

Remove the mixer head from the base by removing the 4 Phillips head screws. Pry off the ring around the rotating part with a flat head screwdriver. Punch out the pin holding the rotating part and remove. Remove the trim strip by removing the two Phillips screws at the rear of the unit. Remove the 4 screws at the bottom of the mixer head. Carefully separate the bottom of the head from the top using a flat screw driver. There will be the power wires connecting the top to the bottom of the unit. It is best to disconnect these wires to avoid breaking them during rest of the procedure. There will be a lot of grease in the gear box of the mixer. The assembly holding the damaged worm gear can now be removed by removing the three screws holding it to the bottom of the mixer head. At this point I removed the grease from the worm gear assembly to allow better inspection. Punch out the pin holding the worm gear to its shaft and remove the shaft. The worm gear is now free and can be replaced. Add some extra grease to the new gear and reassemble the mixer in the reverse order.

replaced

the plastic covering the thumb screw cracked almost half way and lost the piece....so the new one is being used to replace this old one...very easy to install

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

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

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.

Just screwed it in

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.

i followed the instructions in video. Thank you joe

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.

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

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

it was a kitchen aid dough mixer, had to take the top portion off and replace the assembly with a new one that holds the teflon gear. You can purchace the gear only and it becomes less expensive, but at the time I didn't take the chance cause the greese was there and didn't want to take a chance. Its a simple repair by removing some cotter pins and phillips head screws.
