KP2671KATRW KitchenAid Mixer - Instructions

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.

replaced planetary assembly. Was not difficult to do.

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.

After trying to make a batch of heavy frosting, my KitchenAid mixer final stopped turning. After watching a video of how to change the grease in a similar model on PartsSelect and seeing it wasn't that hard to take apart, I decided to give it a try myself. Removing the cover exposed a completely worn gear drive. Luckily, it was easy to determine which parts needed replacing and PartSelect sent them in no time. Once I put everything back together, it sounded terrible which was pretty tough to take. As it turned out, the problem was flecks of metal from the gear were still in the grease and were getting caught in the mechanism. Once I thoroughly cleaned all the grease out and gave it some fresh grease the machine worked great. Much better than before. I only wish I had swapped the grease out at the same time. Thank you PartsSelect for saving me hundreds of dollars on a new machine!

Worm gear strips usually after the lower gear housing breaks. Tore down cleaned grease and shrapnel out, replace stripped worm gear and lower housing. It's convenient that the lower housing plate comes assembled with new bushing and gear. This is now the third one of these expensive mixers I have repaired, word got out that I fix them, and this is a very common problem. Repairs have been for friends and Church, so I don't charge any labor, it's kind of fun, messy, but fun. Note to Kitchen Aid: Please strengthen lower gear case.

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

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!!!!

After removing the single philips screw from the back of the unit, the metal band will come off. Under the band you will find 4 phillips screws. Remove them to get the cover off of the unit. Once open, access the gear box in front by removing the four philips screws holding the gear box cover down. Remove any old grease from the unit as there may be pieces of broken gear in the grease that will damage the new gears. I used a small plastic scraper, some paper towel, rubber gloves and q-tips to get all of the grease out. Try to make a note of how much grease you removed and from where, so that you can replace about that amount later and in the correct spots. To remove the bevel gear remove the split ring holding the bevel gear down on the vertical drive shaft. Once the ring is removed it will be easier to move the bevel gear, but I found that it was somewhat press fitted on the shaft and I needed to use some channel locks to gently rock it back and forth to get it moving up the shaft. I then, also, (since I was in there) replaced the worm gear underneath the bevel gear by tapping the retaining pin out of the hole above the worm gear and then tapping down on the vertical drive shaft with a hammer to push the planetary gear down and out of the unit. Once free, I then regreased the planetary and reinserted it in the holder taking care to align the gears on the shaft and the panetary housing. Then I tapped the worm gear all the way down to the base taking care to keep the recessed notch on the top of the worm gear parallel to the pin hole above it. Then I replace then pin and tapped the bevel gear down onto the top of the worm gear and replaced the split ring. Realigned all of the horizontal and vertical gears and then repacked the grease. Closed up the gear box and test ran the unit on low. THen closed up the rest of the unit in reverse of opening.

Noticed worm gear was worn out, ordered the parts, it came very next day. On YouTube instructions were very easy to follow. Important point to remember,I washed the parts in water with chlorine in it. Retaking ring was tough to take out, as I did not have parrot beak plier, could not find it at Home Depot or Lows. Putting the retaining ring I used circular nut driver, to press it on the shaft to slide down by hammering it. While assembling follow the instruction step by step from the you tube. Machine works smoothly. Performing well. Thanks to part select, excellent web page, efficient delivery. I would recommend them to all.

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.

Open the case, removed gear cover, removed planetary drive shaft and gear, replaced with new planetary and reassemble.
