5KSM185PSBFT4 Whirlpool Mixer - Instructions

Replacing the base retaining bracket(what KitchenAid calls the screw cap) solved the problem immediately. The entire replacement effort took no more than a minute requiring removing 3 screws, discarding the old base, putting in the new one, and putting the screws back in. PartSelect was very easy to do business with. They shipped the part the day I ordered it and it arrived as scheduled. Can't be easier than that.

and I thought replacing the hinge pin would fix it, I used an awl to push out the old pin then used the new pin to push the old one all the way out. That did not fix the problem. Went to a store to look over a new one and saw that the screw under the head at the hinge point on the new machines was not screwed in tight. Turns out that screw is the "bumper" for the head against the neck, so the head is held back by the screw. FIXED

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

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.

Order part through parts select. it only took 3 days to receive part. The mixer was very easy to take apart and to replace the gear. it was back together in about 20 min. The video from kitchen aid to repair the unit is awsome. Thanks

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.

Replaced gears and cleaned and re-greased gears

1. Removed the mixer from the base by removeing the pivot pin at the mixer base support. 2. removed the retainer ring from the housing. 3. removed the pin from the shaft. 4. removed 5 philips machine screws from the round base. 5. removed the round base from the mixer housing. 6. removed the o-ring from the shaft. 7. removed the shaft and large worm/pinion gear from the shaft. 8. pressed out the pinion drive gear from the mixer. The reverse operation repaired the mixer to new condition.

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.

removed one screw from back cover, loosened two screws holding speed control plate, removed one wire at a time from old unit to new, screwed two top screws back on mixer,plug mixer back in, adjust speed control screws until I reached correct speed, put back cover back on

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

Neither motor brush popped out with the spring as shown on videos. Both appear to have disintegrated in part and had to be chiseled out delicately using and ice pick and tapping gently with a hammer. This left a carbon powder and pieces of the old brushes on the counter. Inserting the new brushes was as easy as shown on the video.

Initially removed carbon brushes then inserted the new carbon brushes. The motor still did not turn on. Then I removed the brushes again, used a flashlight to look in the hole where the carbon brushes are installed. I noticed that there was a square notch on one side of the hole. I then reinstalled the carbon brushes, ensuring that the beveled side of the carbon brush was installed so it lines up with the square notch. This allows the carbon brushes to touch the motor. I turned the unit on and it worked.

This is the easiest repair ever! I removed the 3 screws, cleaned around the area with a sponge and kitchen cleaner and put on the new cap. The screws went back in easily and voila ! Done!
