KSM90PSBU KitchenAid Mixer - Instructions

After removing one screw at the top of the rear housing, and the housing you have clear access to the wire attachment points. I useg a very small screw drive to unlock the female disconnects from the male connectors.I disconnected and connected the wires one at a time to be certain I did not misconnect the wires. The ground wire is attached with a screw. The moulded strain releif is pushed onto the main housing cutout and the rear housing tabs slip into pockets at the bottom of the main housing. The screw at the top holds it is place.

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!

I looked on line found the product sent in information and 3 days later was in my mailbox,great service and ease of ordering. thanks marjorie

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.

It only involves reinserting the beater . And the thumb-screw was falling out so I cleaned the area and replaced the thumb screw. Very simple and easily done.

unscrewed old part, put in new part.New part much better design than old one. Works great. Your service is great. Had the part in a 2-3 days. Awesome.

Took it to repair shop

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

Replaced electrical board and speed control plate. cleaned and added new grease. Removed agitator cover and replaced agitator with new. Problem agitator did not match existing. Old agitator was drilled and tapped for a plate to hold gear in place. Tried one without does not work.

I watched the video twice and made the repairs

followed the instruction on you tube

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 .

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
