4KG25H3XER5 KitchenAid Mixer - Instructions

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

watched the youtube video on how to repair a Kitchenaid Pro 600.

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!!!!

Removed top cover, remove snap-ring on shaft, slide top gear and worm gear off. Clean all the grease out and clean parts. Installed new worm gear and parts. Repacked with new grease, careful not to much, leaving room for expansion.

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.

Remove Beaty band, one screw. Remove four screws holding top. Remove worm gear, by simply lifting it out. Removed all grease. Repacked with fresh grease. Take out gear case/ transmission bearing, clear all old grease, repack with new grease. Install into new gear case housing. Assemble, and Repack new worm gear and front and rear worm gear bearings, utilize old washers (2), and one small ball bearing washer. Rotate worn gear and bushing to spread the new grease throughout the gears. Replace top cover, four screws . Replace beauty ring, one screw. Run unit for 20 to 30 seconds, under no load to distribute the new grease. Works like a charm. 45 minutes to one hour. To complete.

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.

took mixer apart down to removal of gear case cover.upon removal of this cover found the bevel gear and hub bevel gear chewed up .removed them both then replaced them both.and also had to solve a clearence problem between the 2 gears they were too loosely meshing. so had to push the hub retainer closer to take up the meshing slack.not sure my repair will hold but i have another set of gears and another solution that will surely fix it.

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.

I replaced the switch component twice and I still have the same problem. I will purchase a new motor now see if that works? I'll post what happens thanks

took off the strap band around mixer, took off the cover (4 screws, took off gear cover (4 screws) took off the retaining ring(used pliers and screwdriver) took off upper gear, took out retaining pin, took off lower gear (becareful to grab the planetary assembly as it will fall out after you take out the retaining pin) cleaned out all of the gear grease (the teeth that were missing were in it. replaced the planetary assembly, lower gear and retaining pin. replaced the upper gear, replaced the retaining ring (used screwdriver and hammer. you have to spread the ring with end of screw driver so it will fit on the shaft then tap lightly with screwdriver and hammer to get it down to the keyway for the ring.) replaced the gear grease with NEW grease, reaplaced the gear cover, replaced the mixer cover, replaced the strap band and plugged it in to test it. IT was quieter than before and works great. i spent less than $30 to repair my 10 year old, out of warranty, Kitchen Aid Mixer. much better than the $32.00 to ship it to factory repair shop and get an estimate to repair. I needed it to make a cake for my nephews wedding. I had my parts in 2 DAYS!!! it was a great experience over all.

Ordered new worm gear and received in a few days. I cleaned out old grease from the gear housing, replaced the worm gear and packed with new grease. Machine runs well now. Easy repair.

removed the cover as stated in the e-mail and followed their recommendations on how to do the repair, the hardest part was removing the retainer clip, job went smoothly. thanks
