4KG25G7XER4 KitchenAid Mixer - Instructions

Replaced the worm gears. Original were ground down as if they were not seated correctly. Ordered the parts and swapped them out. I do not own a retaining clip removal tool. This was the most difficult, trying to open the clip using 2 needle nose pliers. It made the repair time longer.

The insertion part of the foot was tapered to fit in the hole in the mixer. Simple pressure was not the answer. So I used a small key, placed it on the bottom of the foot, after applying a little vegetable oil on the foot, and tapped it into place. Worked well.Joe

Took the mixer apart many times. Grease all over the place. put new gears in still noisy. The worm gear must have been cut wrong. The noise still there. The part select sent out a new worm gear. I did not put it in yet. I put the old worm gear in and the noise stopped even though it shows wear. Have not decided whether I will put it in yet.I would also like to add that the people that I talked to at the this site were very very helpful and great just great---------

Researched the internet for a diagram of the mixer and used that to take it apart, clean everything, then install the new gear and new grease. Works great so far.

My husband removed screws and took top off mixer. Then he took out the gears and cleaned them from all the grease. After he did that he could see the gears that were all worn. We went on line ordered the new gears and in a couple of days the parts were here and he put them back in and greased it all again and put the top and screws back in place. Mixer sounds much quieter. Thank you.

Easily took apart and replaced gears. thanks

Disassambled the gear-train.Removed all broken pieces and grease from gear case. Cleaned gear case and all parts. Reassembled gear-train with new parts and packed all with suitable quantity of new grease. Test run with variable speeds assuming working smoothly.

followed directions given, removed all the old grease .did a short test run , then replaced with new grease. the reason the gear was striped was my fault mixing too much bread at one time. we have a coffee house and use the mixer every day.

Removed top cover of mixer which was very easy. Then marked the 4 wires so they could be plugged back to new switch correctly. Removed 2 attaching screws to remove switch and one squeeze connector. Installed new switch after plugging on 4 wires. Snapped squeeze connector in place. Reinstalled top cover.

Remove and replace gear case. Apply food grade grease secure with screws.

1. Removed the decorative band then the upper motor cover.
2. Removed the upper gear case cover. Found one of the two alignment pins broken.
3. Inspected gears.
4. Cleaned out old grease.
5. Repacked with new food grade grease.
6. Reassembled.

I followed the instructional video closely. My old circuit board was labeled and laid out slightly differently than the new one, so in addition to labeling the wires with "color" or "motor" label from the old board, I also made sure to label with more identifiers that were included on both boards such as "P1" or "P2". Once I labeled the wires with all the information, removal of the old board and installation of the new board was straightforward. This isn't the first repair I've made on my KitchenAid but it was by far the simplest.

Removed 2 screws holding the switch unplugged the one at a time.
opened the gear box cover 4 Philip screws, cleaned out the grease
removed the pinion gear, removed pin, removed the planet gear assembly replaced gears in reversed order greased it up put gear cover back on and tested worked great.

Watched utube
video how to repair and ordered part, easy

3d time in 20 years, but the mixer itself is built like they did 20 yrs ago PartSelect had the part in my mail box in *20 hours* from online order!
See https://www.ereplacementparts.com/kitchenaid-4kp26m1xmc4-professional-stand-mixer-parts-c-114958_114959_115101.html for instructions.
BUT - they changed the design so a power switch previously separate from (to the left of) the circuit board is now a microswitch integrated on the board, leaving you with ONE LESS WIRE.
Attached is the fix diagram & directions for the new design.
