KG25H0XBK4 KitchenAid Mixer - Instructions

The worm gear was defective. Called the 888 number and received excellent service. Said I would receive a refund and a new one in the mail.

Dear Customer Service,

I just would like to express my gratitude for your wonderful service. I received my part for my Kitchen aide mixer on time as promised. The part fit perfectly. Thanks you PartSelect for being there.
What a Great Site!

A Happy Customer!

it just screw in.

Simply placed it in the slot and pounded until firmly in with a soft mallet. Thanks to your site I was able to find the piece easily and very inexpensively. Thank you so much. I would die if I couldn't fix this machine.

Remove screw at back of mixer,remove metal sleve and remove three more screws (front and sides. remove screws and plastic cap of gear box then remove holding ring in post and remove damaged ring installation is opposed of removal.

Took top apart and installed new housing and two gears. Reassembled

Removed plastic cover, removed grease and put in new mixer and put new cover back on.

I did not do the repair myself, however, I contacted a suggested service company which in turn was a company I had used before when I had problems with my JenAir microwave. Excellent service, prompt and very professional. Thank you JenAir for your assistance in providing promptly the parts needed to complete this job.

Took screw off band. This revealed 4 screws to upper housing. Removed 4 screws and lifted upper housing off . To my surprise I found no screws holding gear housing cover in place. You could tell they were there at one time. Should be 4. I removed cover disasembled what was left of gears. Cleaned old grease ordered parts. Thought since there was only 1 screw on diagram it would ship 4. No big deal. After recieving parts further inspection revealed no screws holding motor in place. This blows me away. Anyway off to local hardware store for more screws. Got home slapped it togethere in 10 minutes. Ordered this off TV about 6 years ago. They must have had it in for repair and forgot to put it back together. All that aside it runs better than ever. Thanks much Michael

disassembled unit gear head and replaced broken part, then reassembled

The repair is actually quite simple. The Snap Ring Pliers are essential. Make sure you clean out all the old grease in the machine and replace with new grease. The metal dust will act like sandpaper and destroy your new gear. There are several videos on YouTube which go through the process of repair and part replacement, I found these quite helpful. Good luck! DIY!!!!

Watched the video. Ordered the parts. Watched the video again. Replaced the worm follower gear and bearings on the worm gear. Added grease. Installed new gear housing. Put it all back together and tested. Works like new. Now I get cakes and goodies again and have a happy wife who thinks I'm super handyman. Thanks

Removed the cover. Removed the gear assembly cover.. Extracted the C clip with a tool. Removed the bevel gear. Pushed out the dowel pin. Used rubber mallet to push the shaft off the worm gear. Replaced the washer and the worm gear. Used a 1/2" diameter PVC, 3" long over the shaft and on the gear to push back the shaft through the gear with rubber mallet. Pushed back the dowel pin. Reinstalled the C clip. Replaced broken hub bevel gear. Added more grease. Placed the gear cover with 4 screws just tight enough to hold the cover but still allows movement. Turned the mixer to the lowest speed. Allow the cover to self adjust so that the gears have the smoothest sound. Tightened the screws while while maintaining the smooth sound. Turned off the power. Replaced the cover.

Used the meat grinder attachment, with the retaining ring too tight for the motor to turn the augur, so a gear stripped and the mixer would not run. I opened the mixer top, removed the transmission cover, removed enough grease to diagnose the problem (6 teeth stripped off the steel worm gear). I ordered a replacement steel worm gear and, while I was at it, a new retaining ring, bevel gear, retaining pin and the large planetary gear, as I could not tell the condition of these until I disassembled the whole gear train. I then removed the gear train components (needed a snap ring pliers to remove the retaining ring -- I don't recommend trying to remove it with an y other tool), washed them in acetone, cleaned out the transmission case and went over it with a magnet to get stray gear tooth remnants, replaced the worm and bevel gears and reassembled, using the original planetary gear, retaining pin and retaining ring. Filled the bottom of the transmission with planetary grease first, then, once the gear train had been replaced, slathered a big pile of grease over it, replaced the transmission cover. The machine then ran perfectly, so I replaced the mixer's top cover and decorative band and was back in business mixing with it about 30 minutes after cleaning the last of the grease off my hands. I should mention, I used a LOT of paper towels for this job. This was a fun job and I was sorry that it was so easy to do, as I enjoy working with gears and grease.

First of all, go to the web site and download the schematics of the model #. It will show all the parts and part #s. Secondly watch a u tube video of the actual strip down process of the professional 600 series stand mixer. With this knowledge, do one of two processes 1: strip down the machine, remove the gears and check for defects- order parts. Or 2: replace all the parts( little money) and have a totally refurbished , smooth running mixer. I kept the good used gears for spares. I replaced 90 % of the internals ( including motor) and have a smooth running machine. I initially burned out the mother 2 months after initial purchase, sent it back under warentee, and received it back . Wen I stripped it down 10 years later, there was very little grease in the gear housing. This is what probable ruined the gears. Use plenty of grease in the housing and gears. The grease is one of the most expensive items, but you can't find it anywhere, so order it, along with everything else, from Parts Select.
