KV25MEXER5 KitchenAid Mixer - Instructions

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

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,

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.

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---------

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

Easily took apart and replaced gears. thanks

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.

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.

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

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.

Remove covers, open gear box, remove lock ring and gears to deterime which gears were bad. Remove old grease, install new gears and pack with new grease.
