KP2671 KitchenAid Mixer - Instructions

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!

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.

You must have new bevel gear and can of food grade grease, ordered together. 1. Remove screw from back of mixer, holding the trim band; remove band. 2. Remove four screws holding the top cover. 3. Remover cover 4. Remove two screws holding the pc board and motor speed control; lift board out of the way. 5. Remove four screws holding gear cover; remove cover. 6. Remove as much gear grease as is accessible; discard. 7. Remove snap ring from vertical shaft holding bevel gear. 8. Remove horizontal shaft/gear by lifting straight up. 9. Remove bevel gear by sliding up shaft. 10. Remove cross pin holding lower gear. 11. Remove lower gear by sliding up shaft. 12. Remove vertical shaft and rotating head by tapping on top of shaft. 13. Clean all grease from gear case and on all gears (ground metal from bevel gear will be in this grease). 14. Clean all grease from inside gear cover. 15. Making certain gear case is now clean of all old grease, use putty knife to place grease in bottom of gear case. 16. Rub light coat of grease on vertical shaft and slide shaft back up into bottom housing. 17. Slide lower bearing back down vertical shaft. 18. Reinstall cross pin holding lower gear. 19. Place grease on lower gear. 20. Slide bevel gear down vertical shaft, making certain recess in underside of bevel gear lines up and sits completely over top of lower gear; when the bevel gear is fuly seated the snap ring groove will just be showing on the vertical shaft. 21. Reinstall snap ring. 22. Lightly grease shaft of both ends og horizontal shaft/gear; make certain ball bearing on front of shaft is also greased. 23. Slide ball bearing, spacer and bronze bushing on front of horizontal shaft. 24. Silde bronze bushing on opposite end of horizontal shaft (flange on bronze bushing is placed facing the gear). 25. Place assembled horizontal shaft/gear into lower gear housing. 26. Liberally grease all gears, 27. Replace gear cover, replace screws. 28. Replace pc board and motor speed control. 29. Plug mixer in and run on lowest speed for at least 10 minutes;increase speed until satisfied gears ar running smoothly. 30. Replace top cover and trim band. Bake something

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

First and foremost, I am not mechanical at all. I typically refer to parts as thing-a-ma-jigs, and whatca-ma-call-its. When it froze up and started to make a loud grinding noise, I guessed it was a gear problem. I decided to try to take it apart, What did I have to lose? If I couldn't figure it out, I would be down a mixer. I was already down one as it was. It was very easy to take apart and I could immediately see what gears needed to be replaced. Parts Select made it very easy to see what parts I needed. And delivery was lightning fast; the next day after it shipped! I found a PDF on line on how to dis-assemble and re-assemble the mixer. I got it together and it mixed for a few minutes and froze again. I took it apart and realized that I didn't have the whatcha-ma-call-it (worm gear) seated properly. Fixed it and put it back together and put it to the test. Working just fine now! Thank you Parts Select for making this very easy!

just attached it

the plastic covering the thumb screw cracked almost half way and lost the piece....so the new one is being used to replace this old one...very easy to install

removed cover. Removed cover over gears. Used lock washer pliers to remove lock washer. Took out gears. Cleaned metal shavings from old gear and grease. Reassembled using new gear. Took about 15 minutes and saved $$ over sending mixer out for the repair.

I unplugged the mixer, then I removed the Phillips screw holding the beauty ring, then removed the 4 screws that hold the motor housing together. I removed the housing top, and unscrewed the speed control switch. I marked each one of the connectors of the switch (there are 4) 1-4 then disconnected the speed sensor from the switch and the motor. Replaced the new sensor and connected that to the new speed control switch. reconnected the connectors to the terminals I took them from ( 1 - 4 ) screwed it into place. replaced the top motor housing, I screwed that back with the four screws. replaced the beauty ring and screw. plugged it in and tested it and it was like new

The KitchenAid is "old school" in that it is held together with simple (but very stout) bolts and screws. I removed about 10 such fasteners, slipped off the gear retainer, and pulled it out. On Sunday, a very nice customer service rep helped me order the right part, but I did the rest on line in a matter of seconds. It shipped on Monday and arrived on Wednesday. Took about 10 minutes to put everything back. I REALLY WISH everything was this easy in 2012!!!

I looked on line found the product sent in information and 3 days later was in my mailbox,great service and ease of ordering. thanks marjorie
