5KP2670-3 KitchenAid Mixer - Instructions

took it apart. more grease all over. Put in all but one gear on the top. The noise is still there going to try to but the old bearings in and try again. I went back to the old worm gear and allmost all the noise stopped. I did put the new bearings in and the other gears. It seems that the gear on the worm gear was cut wrong. The noise was tear able. I tried the different parts I ordered one at a time. To find out which one stopped the noise. Every time I took a part I had grease all over. It took so long every time I put in a new part to put the trans back together again. I had grease all over.

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!!!!

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.
