4KP26M1XNP5 KitchenAid Mixer - Instructions

Removed the top housing.
Visual inspection revealed a cracked gear housing.
Removed the 4 screws to remove the housing.
Removed the gear retaining clip and inspected the gears and pin.
The housing was the only problem.
Noticed the plastic housing locating pins were missing and were stuck in the bottom aluminum housing pin receptacles. Carefully drilled out and cleaned debris.
Installed the new gear housing with gasket.
Tested the machine then replaced the top housing.

Self explanatory lol

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.

Removed screws holding top, then removed the switch retaining screws. Removed and replaced switch wires and re assembled cover.

Removed cover, removed retaining clip from shaft. Removed gear, removed shaft pin. Removed shaft. Installed new planetary and installed pin, gear, retaining clip. Installed covers. Tested Sat.

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!

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.

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.

Skewer the screw in with my fingers,

Opened the gear housing and removed all gears. Cleaned out all grease. Biggest issue was getting the retaining ring; very tight. Gears were difficult to pull easily. In replacing gears they did not sit easily and took a little rubber hammer to re position worm and upper gear. Be sure to have the right grease for food devices and don’t under grease. And have patience of which I have a short supply.

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.

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---------

Dismantled gear box pulled all gears out and replaced worm gears

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

Easy ; remove belt ( 1 screw ) remove cover , and there is the complete drive . I still need the top plastic cover which is cracked and broken where the bolts go through . Please quote this part .Conradt

Easily took apart and replaced gears. thanks
